20210201696
The present disclosure relates to technologies for providing audio, video, and physiological feedback to a speaker.
Public speaking is a key talent. From teaching to selling, from high politics to small group meetings, being able to effectively convey ideas and convincingly present arguments is fundamental to achieving one's goals. Career advancement may be slowed or accelerated based, at least in part, on public speaking skills. Individuals engaged in many professions realize the importance of public speaking skills and often attempt to improve their skills to improve their promotability. However, improving public speaking ability is difficult because a large gap often exists between theoretical knowledge and practical proficiency. Just as with any other physical activity, training requires a human being paying attention at your performance and providing feedback and guidance. Individual coaching can be expensive and few have the time or financial resources to obtain such coaching. Furthermore, a single speaking coach may be insufficient to provide feedback on discourse processing, intonation, body movement, facial expression, and similar.
Features and advantages of various embodiments of the claimed subject matter will become apparent as the following Detailed Description proceeds, and upon reference to the Drawings, wherein like numerals designate like parts, and in which:
Although the following Detailed Description will proceed with reference being made to illustrative embodiments, many alternatives, modifications and variations thereof will be apparent to those skilled in the art.
The systems, methods, and apparatuses disclosed herein provide automated speech coaching to individuals by analyzing the performance of the speaker and providing feedback on detected issues with speech, movement, gestures, and physiology. The systems, methods, and apparatuses disclosed herein provide general directions, guidance, and specific advice to improve their public speaking skills. The coaching system may include video and audio acquisition equipment that is used to autonomously identify unwanted, undesirable, or culturally inappropriate communication patterns, gestures, or traits of the speaker. Such patterns, gestures, and traits may arise from verbal disfluencies, inappropriate expressions, suboptimal body languages, distracting gestures, improper presentation styles, and similar.
The systems, methods, and apparatuses disclosed herein also include a dialogue management system trained to play the role of a public speaking expert. The systems and methods disclosed herein will collect audio, video, and/or biometric information of the system user, analyze the information to autonomously identify unwanted or undesired visual and/or audio patterns, and provide an output to the system user that not only identifies the unwanted or undesirable elements, but also provides corrective action to address the unwanted or undesirable elements. In at least some implementations, the systems, methods, and apparatuses disclosed herein may also make use of an anthropomorphic three-dimensional figure that impersonates the system user and provides visual feedback to the system user. Such an output is useful for not only making the communication speaker-coach more natural, but also provide examples, feedback, and recommendations regarding body language, gestures, facial expressions, etc.
A public speaking coaching system is provided. The system may include: processor circuitry; and at least one storage device that includes processor-readable instructions that, when executed by the processor circuitry, cause the processor circuitry to provide: data gathering circuitry to collect, during a presentation by a speaker, at least one of: audio data; video data; or biometric data; presentation analysis circuitry to detect an occurrence during the presentation by the speaker of at least one of: a defined audio event; a defined video event; or a defined biometric event; and presenter feedback circuitry to selectively provide feedback to the speaker, the feedback selected based upon at least one of: the defined audio event; the defined video event; or the defined biometric event.
A public speaking coaching method is provided. The method may include: collecting, by data gathering circuitry during a presentation by a speaker, at least one of: audio data; video data; or biometric data; detecting, by presentation analysis circuitry, an occurrence during the presentation by the speaker of at least one of: a defined audio event; a defined video event; or a defined biometric event; and selectively providing, by presenter feedback circuitry, feedback to the speaker, the feedback selected based upon at least one of: the defined audio event; the defined video event; or the defined biometric event.
A non-transitory computer readable medium is provided. The non-transitory computer readable medium may include instructions that when executed by processor circuitry, cause the processor circuitry to provide data gathering circuitry, presentation analysis circuitry, and presenter feedback circuitry. The processor circuitry to: collect, by the data gathering circuitry during a presentation by a speaker, at least one of: audio data; video data; or biometric data; detect, by the presentation analysis circuitry, an occurrence during the presentation by the speaker of at least one of: a defined audio event; a defined video event; or a defined biometric event; and selectively provide, by the presenter feedback circuitry, feedback to the speaker, the feedback selected based upon at least one of: the defined audio event; the defined video event; or the defined biometric event.
A public speaking coaching system is provided. The system may include: means for collecting at least one of: audio data; video data; or biometric data; means for detecting an occurrence during the presentation by the speaker of at least one of: a defined audio event; a defined video event; or a defined biometric event; and means for selectively providing feedback to the speaker, the feedback selected based upon at least one of: the defined audio event; the defined video event; or the defined biometric event.
As used herein the terms “top,” “bottom,” “lowermost,” and “uppermost” when used in relationship to one or more elements are intended to convey a relative rather than absolute physical configuration. Thus, an element described as an “uppermost element” or a “top element” in a device may instead form the “lowermost element” or “bottom element” in the device when the device is inverted. Similarly, an element described as the “lowermost element” or “bottom element” in the device may instead form the “uppermost element” or “top element” in the device when the device is inverted.
As used herein, the term “logically associated” when used in reference to a number of objects, systems, or elements, is intended to convey the existence of a relationship between the objects, systems, or elements such that access to one object, system, or element exposes the remaining objects, systems, or elements having a “logical association” with or to the accessed object, system, or element. An example “logical association” exists between relational databases where access to an element in a first database may provide information and/or data from one or more elements in a number of additional databases, each having an identified relationship to the accessed element. In another example, if “A” is logically associated with “B,” accessing “A” will expose or otherwise draw information and/or data from “B,” and vice-versa.
The processor circuitry 110 may include any number and/or combination of electronic components, semiconductor devices, and/or logic elements capable of providing at least the data gathering circuitry 112, the presentation analysis circuitry 114 and the presenter feedback circuitry 116. In some implementations, the processor circuitry 110 may include one or more single- or multi-core processors or microprocessors. In some implementations, the processor circuitry 110 may include an application specific integrated circuit (ASIC); a system-on-a-chip (SoC), or similar device.
In embodiments, the data gathering circuitry 112 may be communicably coupled to one or more data acquisition devices 102. In some implementations, the data gathering circuitry 112 may be communicably coupled to one or more wearable data gathering devices 104 worn by the speaker 130. The wearable data gathering devices 104 may communicably couple to the data gathering circuitry 112 via one or more tethered connections (e.g., via a Universal Serial Bus or “USB” connection) or via one or more wireless connections (e.g., via a BLUETOOTH®, near field communication (“NFC”), Ethernet, or cellular connection. Example data gathering devices 102 may include, but are not limited to: one or more audio microphones and/or microphone arrays; one or more video cameras and/or camera arrays; one or more still image cameras or camera arrays; or combinations thereof. Example wearable data gathering devices 104 may include, but are not limited to: one or more biometric sensors, one or more physiological monitors, one or more wearable processor based devices; one or more microphones and/or microphone arrays; one or more video cameras and/or video camera arrays; or, combinations thereof. In some implementations, all or a portion of the wearable data gathering devices 104 may be disposed partially or completely in, on, or about a wearable device such as a smartwatch, or eyewear.
The data gathering devices 102 and the wearable data gathering devices 104 provide information and/or data 132 to the data gathering circuitry 112. In embodiments, some or all of the data gathering devices 102 and/or the wearable data gathering devices 104 may provide information and/or data 132 to the data gathering circuitry 112 on a continuous, intermittent, periodic, or aperiodic basis. In some implementations, the data gathering circuitry 112 may autonomously poll or otherwise call for data from one or more data gathering devices 102 and/or wearable data gathering devices 104 at increasing or decreasing data transfer rates and/or frequencies. For example, if information and/or data 132 collected by the data gathering circuitry 112 indicates a potential increasing stress level for the speaker 130, the data collection rate and/or frequency may be increased to provide enhanced information and/or data to the presentation analysis circuitry 114. In another example, if information and/or data 132 collected by the data gathering circuitry 112 indicates a potential increasing stress level during public questioning, the data gathering circuitry 112 may increase the data gathering rate and/or frequency during periods when public questions are presented to the speaker 132.
In some implementations, all or a portion of the information and/or data gathered by the data gathering circuitry 112 may be forwarded to the presentation analysis circuitry 114. In some implementations, all or a portion of the information and/or data gathered by the data gathering circuitry 112 may be stored or otherwise retained in one or more data structures, data stores, or databases disposed in, on, or about the storage device 122.
In embodiments, the presentation analysis circuitry 114 may analyze at least a portion of the information and/or data provided by the data gathering circuitry 112 on a continuous, intermittent, periodic, or aperiodic basis. For example, in one implementation the presentation analysis circuitry 114 may analyze the information and/or data provided by the data gathering circuitry 112 on a real-time or near real-time basis such that feedback is provided to the speaker 130 in a timely manner Such an arrangement beneficially permits the use of the speech coaching system 100 to provide near instant feedback, coaching, and guidance to a speaker 130.
In other embodiments, the presentation analysis circuitry 114 may retrieve from the storage device 122 at least a portion of the information and/or data stored or otherwise retained thereon by the data gathering circuitry 112. Such an arrangement permits a speaker 130 to “record” an entire presentation, review the presentation later, and receive feedback in a post-presentation setting more conducive to critical analysis of the feedback provided to the speaker.
The presentation analysis circuitry 114 may include any number and/or combination of systems and/or devices capable of receiving information and/or data from either or both the data gathering circuitry 112 and/or the storage device 122, analyzing the received information and/or data to identify speaker characteristics, mannerisms, verbal disfluencies, actions, physical activities and similar verbal and non-verbal elements that either positively or negatively impact the ability of the speaker 130 to deliver a message to an audience.
In embodiments, the presentation analysis circuitry 114 may analyze audio information and/or data to identify verbal disfluencies that are repeated during at least a portion of the presentation. In some implementations, the presentation analysis circuitry 114 may employ other voice and/or pattern recognition technology to identify strengths or weaknesses in the speaker's diction, volume, voice, or style. In some implementations, the presentation analysis circuitry 114 may analyze the content of the presentation and compare the content against cultural standards for a proposed target audience to identify words, symbols, and/or mannerisms that may be culturally inappropriate or offensive to the target audience. In some implementations, the presentation analysis circuitry 114 may compare the pronunciation of the content in at least a portion of the presentation against stored pronunciation information and/or data. In some implementations, the presentation analysis circuitry 114 may determine an appropriate mode or tone based on the content of the audio information and/or data provided by the speaker 130. Such information and/or data may be used by the presentation analysis circuitry 114 to provide the speaker with an indication of whether the tone or mode of the presentation is appropriate or consistent with the content of the presentation.
The presentation analysis circuitry 114 may analyze video information and/or data to identify posture, movement, and physical mannerisms that occur during at least a portion of the presentation. In some implementations, the presentation analysis circuitry 114 may employ pattern recognition technology to identify strengths or weaknesses in the speaker's physical posture, movement, and/or mannerisms. In some implementations, the presentation analysis circuitry 114 may convert at least a portion of the speaker 130 into a wireframe and compare the positioning and/or movement of the wireframe with acceptable or preferred positions or movement. For example, the presentation analysis circuitry 114 may compare the positioning of wireframe derived from the speaker 130 against one or more historical and/or culturally acceptable assertive positions that improve the effectiveness of the speaker's message on an audience. In some implementations, the presentation analysis circuitry 114 may acquire one or more images of the speaker's face and/or body—such images may then be used to facilitate the generation of one or more speaker avatar outputs by the presenter feedback circuitry 116. Movements identified by the presentation analysis circuitry 114 may include, but are not limited to, hand gestures, use of on-stage items such as podiums and lecterns for support, slumping, slouching, leaning, and other physiological elements that enhance or decrease the effectiveness of a presentation by the speaker 130. For example, the presentation analysis circuitry 114 may identify a slumping posture or leaning on a lectern or podium as inappropriate during an upbeat portion of the speaker's presentation as assessed by the audio portion of the presentation.
The presentation analysis circuitry 114 may include facial analysis circuitry capable of detecting a facial expressions indicative of a variety of emotions such as happiness, sadness, grief, sorrow, earnestness, and similar. In some implementations, the presentation analysis circuitry 114 may determine an appropriate facial expression, posture, and/or pose based on the content of the audio information and/or data provided by the speaker 130. Such information and/or data may be used by the presentation analysis circuitry 114 to provide the speaker with an indication of whether the facial expressions and/or physical pose or posture is appropriate and/or consistent with the content of the speaker's presentation. For example, the presentation analysis circuitry 114 may identify a facial expression such as a smile or laugh as inappropriate during a solemn portion of the speaker's presentation as assessed by the audio portion of the presentation.
The presentation analysis circuitry 114 may analyze biometric information and/or data to identify stressors or other elements of a presentation having either a positive or negative impact on the speaker 130. In some implementations, such biometric information and/or data may include, but is not limited to: pulse rate; skin conductivity; blood pressure; skin temperature; blood oxygen concentration; respiration rate; step counter (i.e., pedometer) or combinations thereof. Such information and/or data may assist the presentation analysis circuitry 114 in identifying portions of a presentation that are more stressful on the speaker 130. Such information may beneficially enable the presenter feedback circuitry 116 to provide feedback to the speaker 130 that is tailored to a particularly stressful portion of the presentation. Such information may also enable the presentation analysis circuitry 114 to analyze a speaker's breathing patterns and rate during the presentation to ensure the speaker is breathing at an acceptable rate and volume to maintain a desirable level of vocal and physical output over the course or duration of the presentation.
The presenter feedback circuitry 116 may include any number and/or combination of systems and/or devices capable of receiving information from the presentation analysis circuitry 114 and generating feedback for the speaker 130. In some implementations, one or more storage devices 124 may store or otherwise retain information and/or data associated with appropriate and/or effective presentation skills, video presentations of appropriate and/or effective presentation skills. In some implementations, the presenter feedback circuitry 116 may include an “expert” or similar system that includes information and/or data collected from a variety of sources. In embodiments, the presenter feedback circuitry 116 may generate a wireframe avatar of the speaker 130. Such a wireframe may be used to provide the speaker with a visual representation, avatar, or similar device that demonstrates a desirable or appropriate facial expression, physical pose or posture, etc. In some implementations, the presenter feedback circuitry 116 may provide feedback that is culturally appropriate or preferable. The presenter feedback circuitry 116 may provide audio feedback, video feedback or any combination thereof.
One or more output devices 108 may be communicably coupled to the presenter feedback circuitry 116 and may be used to provide either a real-time or delayed feedback output 118 to the speaker 130. The one or more output devices 108 may include, but are not limited to: one or more video output devices, one or more audio output devices, one or more haptic output devices, or combinations thereof. In some implementations, at least some of the output devices may be disposed in, on, or about one or more wearable devices 109, such as a smart watch or similar processor based wearable device.
In some implementations, some or all of the processor circuitry 110, the data gathering circuitry 112, the presentation analysis circuitry 114, the presenter feedback circuitry 116, and/or the storage devices 122, 124 may be disposed remote from the data gathering devices 102 and/or the one or more output devices 108. For example, in some embodiments, some or all of the processor circuitry 110, the data gathering circuitry 112, the presentation analysis circuitry 114, the presenter feedback circuitry 116, and/or the storage device 122, 124 may be provided as a remote cloud-based service and the data gathering devices 102 and/or the one or more output devices 108 may be disposed in a local device such as a laptop computer, a desktop computer, or a smartphone.
The audio processing circuitry 210 includes speech recognition circuitry 212, natural language understanding circuitry 214, sentiment analysis circuitry 216, and prosody modeling circuitry 218. The audio processing circuitry 210 receives audio information and/or data from the data gathering circuitry 112 (e.g., audio capture devices and/or audio capture device arrays not shown in
The artificial vision circuitry 220 includes gesture recognition circuitry 222, facial expression recognition circuitry 224, eye tracking circuitry 226, and body movement circuitry 228. The artificial vision circuitry 220 receives video information and/or data from the data gathering circuitry 112 (e.g., video and/or still cameras and/or camera arrays—not shown in
In some implementations, the audio processing circuitry 210 may permit the speaker 130 to ask questions regarding the presentation. For example, the speaker 130 may ask the speech coaching system 200 for advice on a specific topic or solicit the speech coaching system 200 for general or specific feedback on one or more aspects of the presentation. In such an instance, the audio processing circuitry 210 may use the speech recognition circuitry 212 and the natural language understanding circuitry 214 to receive and interpret the request by the speaker 130. In some implementations, the speech coaching system 200 may also use at least one of the sentiment analysis circuitry 216, gesture recognition circuitry 222, and/or facial expression recognition circuitry 224 in receiving and interpreting the request by the speaker 130.
The presenter feedback circuitry 116 includes audio output circuitry 230, visual output circuitry 240, and tactile output circuitry 250. In implementations, the audio output circuitry 230 may include text-to-speech circuitry 232 that may be used to synthesize audio feedback 118A provided to the speaker 130. In implementations, the visual output circuitry 240 may include avatar generation circuitry 242 that may be used to generate an avatar representing the speaker 130. The avatar may then be used by the speech coaching system 200 to provide graphical feedback output 118B to the speaker 130. The tactile output circuitry 250 may include haptic feedback circuitry 252 capable of providing a tap or vibration sensible by the user 130. In some implementations, such haptic feedback circuitry 252 may be disposed, at least in part, in one or more wearable devices, such as a smartwatch capable of delivering one or more forms of haptic feedback to the user 130.
In embodiments, the data gathering circuitry 112 may output all or a portion of the received audio data and/or information 310A and/or all or a portion of the received video data and/or information 320A to the one or more data storage devices 122. In other embodiments, the data gathering circuitry 112 may output all or a portion of the received audio data and/or information 310B and/or all or a portion of the received video data and/or information 320B to the presentation analysis circuitry 114.
In some implementations, the data gathering circuitry 112 may pass all or a portion of the received audio information and/or data 132A and all or a portion of the received video information and/or data 132B unaltered to either the one or more storage devices 122 and/or the presentation analysis circuitry 114. In other implementations, the data gathering circuitry 112 may filter, alter, enhance, or otherwise modify all or a portion of the received audio information and/or data 132A and all or a portion of the received video information and/or data 132B prior to storing the information and/or data on the one or more storage devices 122 and/or passing the information and/or data to the presentation analysis circuitry 114.
In some implementations, the presentation analysis circuitry 114 may compare various segments, sections, or portions of received audio data 410 and/or video data 420 to detect recurring or repeated patterns such as repetitive words or phrases (e.g., “um,” “uh,” “you know,” “I mean”) or repetitive physical actions (e.g., hand gestures, swaying, rocking). In some implementations, the presentation analysis circuitry 114 may compare at least a portion of the received audio data 410, video data 420, and/or biometric data 430 to audio, video, and biometric data libraries saved in one or more data stores, data structures, or databases stored or otherwise retained on the one or more storage devices 122. Such libraries may be populated with audio, video, and biometric data selected based upon defined presentation strengths or weaknesses. Such libraries may be populated with audio, video, and biometric data selected based upon cultural norms or mores of the expected audience of the presentation. Such libraries may be a part or portion of an “expert” or similar system that is periodically, intermittently, or continuously updated to reflect current trends and technological developments. Such libraries may be tailored (i.e., contain audio, video, and biometric data relevant) to a technical field, technology, audience education level, or similar. Such libraries may be populated with audio, video, and biometric data selected based upon the expected sophistication and/or knowledge of the proposed audience (e.g., high school, undergraduate, graduate educated). Such libraries may be populated with one or more languages that are not native to the speaker 130 and may assist the speaker in forming the proper grammar and diction to provide the presentation in a non-native foreign language.
In embodiments, the presentation analysis circuitry 114 may determine whether the received audio data 410 includes data indicative of an audio presentation event 450. Such audio presentation events 450 may include, but are not limited to, repeated phrases, idioms, mispronunciations, verbal disfluencies, colloquialisms, and similar. Once such an audio presentation event 450 is detected, the presentation analysis circuitry 114 forwards information indicative of the audio presentation event 450 to the presenter feedback circuitry 116. Such information may include, but is not limited to, the type of audio presentation event 450, the elapsed presentation time at the start of the audio presentation event 450, and the duration of the audio presentation event 450. The presentation analysis circuitry 114 may also forward data indicative of the repeated phrases, idioms, mispronunciations, verbal disfluencies, or colloquialisms to the presenter feedback circuitry 116.
In some implementations, the presentation analysis circuitry 114 may detect data in the received audio data 410 indicative of one or more undesirable or culturally inappropriate words, expressions, colloquialisms, idioms, phrases or similar. The presentation analysis circuitry 114 may forward data indicative of such a culturally inappropriate audio presentation event to the presenter feedback circuitry 116. The presentation analysis circuitry 114 may also forward data indicative of the culturally inappropriate audio content to the presenter feedback circuitry 116.
In embodiments, the presentation analysis circuitry 114 may determine whether the received video data 420 includes data indicative of a video presentation event 460. Such video presentation events 460 may include, but are not limited to, an undesirable or inappropriate posture, gesture, position, movement, facial expression, eye position, hand position, or similar that detract, distract, or divert audience attention and/or reduce the effectiveness of the message conveyed by the speaker 130. Once such a video presentation event 460 is detected, presentation analysis circuitry 114 forwards information indicative of the video presentation event 460 to the presenter feedback circuitry 116. Such information may include, but is not limited to, the type of video presentation event 460, the elapsed presentation time at the start of the video presentation event 460, and the duration of the video presentation event 460. The presentation analysis circuitry 114 may also forward data indicative of the undesirable or inappropriate posture, gesture, position, movement, facial expression, eye position, or hand position to the presenter feedback circuitry 116.
For example, the presentation analysis circuitry 114 may detect the speaker is leaning on a lectern or podium while delivering the presentation. Such a posture would be considered inappropriate and, in response, the presentation analysis circuitry 114 forwards data indicative of the video presentation event 460 to the presenter feedback circuitry 116. In another example, the speaker may inadvertently make one or more hand gestures considered culturally offensive to at least a portion of the audience. Such gestures would be considered inappropriate and, in response, the presentation analysis circuitry 114 forwards data indicative of a video presentation event 460 to the presenter feedback circuitry 116.
In embodiments, the presentation analysis circuitry 114 may determine whether the received biometric data 430 includes data indicative of a biometric presentation event 470. Such biometric presentation events 470 may include, but are not limited to, an increase in the speaker's heart rate, an increase in the speaker's skin conductivity, an increase in the speaker's blood pressure, an increase/decrease in the speaker's body temperature, an increase/decrease in the speaker's respiration rate, an increase/decrease in the speaker's respiration volume, and similar. Such biometric changes may provide an early indication of those portions of the presentation that increase or decrease the stress level of the speaker 130. Responsive to detecting a biometric presentation event 470, the presentation analysis circuitry 114 forwards information indicative of the biometric presentation event 470 to the presenter feedback circuitry 116. Such information may include, but is not limited to, the type of biometric presentation event 470, the elapsed time at the start of the biometric presentation event 470, and the duration of the biometric presentation event 470. The presentation analysis circuitry 114 may also forward data indicative of the increase in the speaker's heart rate, increase in the speaker's skin conductivity, increase in the speaker's blood pressure, increase/decrease in the speaker's body temperature, increase/decrease in the speaker's respiration rate, and/or increase/decrease in the speaker's respiration volume to the presenter feedback circuitry 116.
In embodiments, an occurrence of at least one of an audio presentation event 450, a video presentation event 460, and a biometric presentation event 470 may cause the presentation analysis circuitry 114 to analyze the received audio data 410, video data 420, and biometric data 430. Analyzing the received audio, video, and biometric data in response to a presentation event permits the presentation analysis circuitry 114 to beneficially and advantageously detect relationships and/or correlations between the received audio, video, and biometric data and the event itself. For example, if a biometric presentation event 470 (e.g., increased heart rate, decreased skin conductivity) occurs contemporaneous with audio data 410 in which the speaker 130 asks the audience for questions, it may indicate the speaker is nervous or uncomfortable answering questions from the audience.
In another example, the presentation analysis circuitry 114 may determine the appropriateness of the speaker's facial expression using video data 420 upon detecting an occurrence of an audio presentation event 450, such as when the audio data 410 indicates a delivery of sad or solemn news to an audience. In such an instance, the presentation analysis circuitry 114 would detect a happy facial expression when conveying the sad or solemn audio information as a video presentation event 460. The presentation analysis circuitry 114 would forward the data indicative of the video presentation event 460 to the presenter feedback circuitry 116. The presentation analysis circuitry 114 would also forward data indicative of the detected audio data 410 and video data 420 used to detect the video presentation event 460. In another example, the presentation analysis circuitry 114 may use the received audio data 410 to determine the appropriateness of the speaker's words considering cultural mores or norms and/or the received video data 420 to determine the appropriateness of the speaker's physical actions considering cultural mores or norms.
In embodiments, the presenter feedback circuitry 116 may select audio, visual, and/or biometric feedback to strengthen or otherwise fortify existing presentation strengths and to correct or otherwise mitigate the effect of existing presentation weaknesses. In embodiments, the feedback provided by the presenter feedback circuitry 116 may be selected based upon cultural norms or mores of the expected audience of the presentation. Such feedback may be a part or portion of an “expert” or similar system that is periodically, intermittently, or continuously updated to reflect current trends and technological developments. Such feedback may be tailored (i.e., contain audio, video, and biometric data relevant) to a technical field, technology, audience education level, or similar. Such feedback may be populated with audio, video, and biometric data selected based upon the expected sophistication and/or knowledge of the proposed audience (e.g., high school, undergraduate, graduate educated). Such feedback may include a language that is not native to the speaker 130 and may assist the speaker in forming the proper grammar and diction to provide the presentation in a non-native foreign language.
In some implementations, the presenter feedback circuitry 116 may provide audio feedback via one or more audio output devices, such as one or more speakers one or more ear pieces, or similar. The presenter feedback circuitry 116 may provide video feedback to the speaker 130 via one or more display devices. In at least some implementations, the presenter feedback circuitry 116 may generate an avatar representing the speaker 130 to provide feedback posture, movement, gesture, and/or facial expression feedback information to the speaker 130. In some implementations, the presenter feedback circuitry 116 may provide haptic feedback to the speaker 130 via one or more devices worn by the speaker 130.
