DETAILED DESCRIPTION

FIG. 1 illustrates a system 2 for providing mood based annotations for audio media, in accordance with embodiments of the present invention. System 2 synchronizes mood based video annotations (e.g., still or animated video images) with audio segments (of an audio file) based on a mood of a speaker of the audio file. The synchronized result (i.e., the video annotations and audio segments) is presented to a listener to capture the attention of the listener. System 2 provides the following functionality:

• 1. Determining a mood of a speaker (in an audio file) based on an analysis of speech presented by the speaker (e.g. by detecting inflection points in the speaker's voice or the speaker's gestures).
• 2. Tagging an audio file with video mood annotations (manually or automatically) based on a determination of a mood of a speaker (in an audio file).
• 3. Providing visualization of speech within an audio file based on mood description objects (e.g., mood annotations such as, inter alia, animated video images, still images, etc.) associated with the speech.

System 2 of FIG. 1 comprises input audio files 5, a mood tag library 10, and output audio files synchronized with mood description objects 6 connected through a network 7 to a computing system 14. Alternatively, input audio files 5, mood tag library 10, and output audio files synchronized with mood description objects 6 may be directly connected to computing system 14 (i.e., without network 7). Network 7 may comprise any type of network including, inter alia, a telephone network, a local area network, (LAN), a wide area network (WAN), the Internet, a wireless network, etc. Computing system 14 may comprise any type of computing system(s) including, inter alia, a computer (PC), an audio recording device, etc. Computing system 14 comprises a memory system 8. Memory system 8 may comprise a single memory system. Alternatively, memory system 8 may comprise a plurality of memory systems. Memory system 8 comprises a software application 17 for providing visualization of moods associated with speech within an audio file.

System 2 enables a process for automatically or manually generating mood based annotations for audio media that is utilized to automatically generate and present (to a listener) visual media (synchronized with the audio media) representing a speaker's mood in order to keep the attention of the listener. An author of the audio media may control placement of the mood based annotations to be coupled with the audio media. Alternatively, a listener (of the audio media) may control placement of the mood based annotations to be coupled with the audio media. Computing system 14 receives input audio (i.e., speech data) from input audio files 5 and associates mood descriptions (i.e., tags describing various human emotions/moods) with portions of the input audio. The mood descriptions are associated with the mood based annotations (e.g., mood description objects) retrieved from a mood tag library 10. Software application 17 generates and presents (to a listener) a synchronized file 6 comprising the audio (i.e., the input audio) synchronized with the associated mood based annotations. The following examples describe various scenarios for generating audio files synchronized with mood based annotations:

EXAMPLE 1

System 2 provides the ability for an audio content author to manually inject moods (to be presented to a listener) in real time while he/she is recording the audio. For example, the input audio may be received from an author (of the input audio) via a recording device and the mood descriptions may be associated (by the author) with the input audio in real time as the input audio is being recorded (as the author speaks). In this scenario, software application 17 assigns the different mood descriptions (i.e., different mood descriptor tags) to the associated portions of the input audio (automatically based on a software analysis or manually based on commands from the author) at specified time frames (in the audio file) resulting in the generation of a mood descriptor file. The mood descriptions are associated with the mood based annotations (e.g., mood description objects such as still or animated video images) retrieved from a mood tag library 10. Software application generates and presents (to a listener) a synchronized file 6 comprising the audio (i.e., the input audio) synchronized with the associated mood based annotations.

EXAMPLE 2

System 2 provides the ability to annotate audio after an audio recording has been completed. An annotation process produces a set of tags that act as descriptors associated with the mood of an author of the audio. Annotations may span intervals in the audio recording or be placed at specified points along the audio recording. For example, the input audio may be fully received from an author (of the input audio) via a recording device and the mood descriptions may be associated (by the author) with the input audio after the input audio has been recorded. In this scenario, the author manually assigns the different mood descriptions (i.e., different mood descriptor tags) to the associated portions of the input audio at specified time frames (in the audio file) resulting in the generation of a mood descriptor file. The mood descriptions are associated with the mood based annotations (e.g., mood description objects such as still or animated video images) retrieved from a mood tag library 10. Software application generates and presents (to a listener) a synchronized file 6 comprising the audio (i.e., the input audio) synchronized with the associated mood based annotations.

EXAMPLE 3

System 2 provides the ability to produce a descriptor of moods (of the author of the audio) based on an automated examination of the audio (e.g., analysis of audio inflection points). For example, software application may sense (by sensing voice inflections) that the author is very excited thereby generating an emotion descriptor that describes rapid hand movement or extreme engagement of hand gestures. In this scenario, input audio may be received from an author (of the input audio) via a recording device and voice inflection points (of the author's voice) are detected and analyzed (by software application 17). The voice inflections may be analyzed by, inter alia, comparing the voice inflections to a predefined table or file describing different voice inflections for individuals including the author of the audio. Based on the analysis, the mood descriptions are automatically associated (by software application 17) with associated portions of the input audio at specified time frames resulting in the generation of a mood descriptor file. The mood descriptions are associated with the mood based annotations (e.g., mood description objects such as, inter alia, still or animated video images of rapid hand movement, extreme engagement of hand gestures, an animated video image of an excited person, an image of a person smiling or laughing, etc) retrieved from a mood tag library 10. Software application generates and presents (to a listener) a synchronized file 6 comprising the audio (i.e., the input audio) synchronized with the associated mood based annotations.

FIG. 2 illustrates a flowchart describing an algorithm used by system 5 of FIG. 1 for providing mood based annotations for audio media in real time during an audio recording process, in accordance with embodiments of the present invention. In step 202, a computer processor of a computing apparatus (e.g., computing system 14 of FIG. 1) receives/records audio (i.e., speech content) from an author (or speaker) of the speech content. In step 204 (i.e., simultaneously while performing step 202), the author labels his/her moods (i.e., adds mood description labels, tags, or data to the audio) at different points during the recording process. The author may label his/her moods via an interface device such as, a hardware interface (e.g., a keyboard, switchboard, a remote computer/device, etc), a software interface (e.g., graphical user interface, a touch screen interface, etc), etc. In step 208, a software application (e.g., software 17 in FIG. 1) executed by a computer processor monitors track time based location markers (in the audio) as the author labels his/her moods. In step 212, the software application associates time frames (associated with the track time based location markers) with associated mood description labels, tags, or data. In step 218, a mood descriptor file is generated. The mood descriptor file comprises a map between portions of the audio (and/or the time frames) and specified descriptions of the mood description labels, tags, or data. In step 224, the mood descriptor file and the audio file is stored. In step 228, the mood descriptor file is mapped to associated mood based annotations from a mood tag library as described, infra with respect to FIG. 5.

FIG. 3 illustrates a flowchart describing an algorithm used by system 5 of FIG. 1 for providing mood based annotations for audio media after an audio recording process, in accordance with embodiments of the present invention. In step 302, a computer processor of a computing apparatus (e.g., computing system 14 of FIG. 1) receives/records an entire audio file (i.e., speech content) from an author (or speaker) of the speech content. In step 304, the author enables playback of the audio file (e.g., via computing system 14 of FIG. 1). In step 306 (i.e., simultaneously during playback of the audio file), the author labels his/her moods (i.e., adds mood description labels, tags, or data to the audio) at different points in the audio file. The author may label his/her moods via an interface device such as, a hardware interface (e.g., a keyboard, switchboard, a remote computer, a remote control, etc), a software interface (e.g., graphical user interface, a touch screen interface, etc), etc. In step 308, a software application (e.g., software 17 in FIG. 1) executed by a computer processor monitors track time based location markers (in the audio) as the author labels his/her moods. Additionally, the software application associates time frames (associated with the track time based location markers) with associated mood description labels, tags, or data. A mood descriptor file is generated. The mood descriptor file comprises a map between portions of the audio (and/or the time frames) and specified descriptions of the mood description labels, tags, or data. In step 310, the mood descriptor file and the audio file is stored. In step 312, the mood descriptor file is mapped to associated mood based annotations from a mood tag library as described, infra with respect to FIG. 5.

FIG. 4 illustrates a flowchart describing an algorithm used by system 5 of FIG. 1 for providing mood based annotations for audio media based on voice analysis, in accordance with embodiments of the present invention. In step 402, a computer processor of a computing apparatus (e.g., computing system 14 of FIG. 1) receives and enables playback of audio file (e.g., via computing system 14 of FIG. 1) comprising speech content from an author (or speaker) of the speech content. In step 404 (i.e., simultaneously during playback of the audio file) voice inflection points or thresholds (in the speech content of the audio file) are determined and labeled. The voice inflection points are associated with predetermined mood description labels, tags, or data describing various moods. The voice inflection points may be associated with the predetermined mood description labels, tags, or data based on a user profile (i.e., comprising sample audio of voice inflections from the author) for the author. The user profile may include sample recordings of the author's voice. If more than one author (or speaker) is detected in the speech content, multiple user profiles (i.e., one for each author) may be used to associate voice inflection points with the predetermined mood description labels, tags, or data. In step 408, a software application (e.g., software 17 in FIG. 1) executed by a computer processor monitors track time based location markers (in the audio) as the voice inflection points or thresholds are labeled. Additionally, the software application associates time frames (associated with the track time based location markers) with associated mood description labels, tags, or data. In step 412, a mood descriptor file is generated. The mood descriptor file comprises a map between portions of the audio (and/or the time frames) and specified descriptions of the mood description labels, tags, or data. In step 418, the mood descriptor file and the audio file is stored. In step 424, the mood descriptor file is mapped to associated mood based annotations from a mood tag library as described, infra with respect to FIG. 5.

FIG. 5 illustrates a flowchart detailing steps 228, 312, and 424 of FIGS. 2-5, in accordance with embodiments of the present invention. In step 502, the computer processor retrieves a mood tag library comprising animated and/or still video objects representing various emotions/moods. The mood tag library may be provided by the author of the audio file or may be provided by a third party. In step 504, a mood tag or label is retrieved from the mood descriptor file. In step 508, a track time based location marker (i.e., associated with the mood tag or label) is extracted from the mood descriptor file. In step 512, the extracted track time based location marker (associated with the mood tag or label) is associated to an applicable animated and/or still video object from the mood tag library. In step 518, it is determined if there are any more mood tags or labels in the mood descriptor file. If it is determined that there are more mood tags or labels in the mood descriptor file then steps 504-518 are repeated until all track time based location markers (associated with mood tags or labels) are associated to an applicable animated and/or still video object from the mood tag library. If it is determined that there are no more mood tags or labels in the mood descriptor file then in step 520, the animated or still objects are synchronized with associated portions of (i.e., specified speech in) the audio file. In step 522, the synchronized files are presented to a listener. Additionally, specified video and/or audio messages may be presented to the listener (at various intervals during presenting the synchronized files). Subsequently, (after the synchronized files are presented) questions associated with the specified video and/or audio messages (or the audio data) are presented to the user. Responses (from the listener) are used to determine if the user has listened to all of the audio data.
