The above and other aspects, features, and advantages of certain embodiments of the present disclosure will be more apparent from the following description taken in conjunction with the accompanying drawings, in which:
It should be noted that these figures are intended to illustrate the general characteristics of methods and/or structure utilized in certain example embodiments and to supplement the written description provided below. These drawings are not, however, to scale and may not precisely reflect the precise structural or performance characteristics of any given embodiment, and should not be translated as defining or limiting the range of values or properties encompassed by example embodiments.
Example embodiments are described in greater detail below with reference to the accompanying drawings.
In the following description, like drawing reference numerals are used for like elements, even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the example embodiments. However, it is apparent that the example embodiments can be practiced without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the description with unnecessary detail.
One or more example embodiments will be described in detail with reference to the accompanying drawings. Example embodiments, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments. Rather, the illustrated embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art. Accordingly, known processes, elements, and techniques, may not be described with respect to some example embodiments. Unless otherwise noted, like reference characters denote like elements throughout the attached drawings and written description, and thus descriptions will not be repeated.
Although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections, should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section, from another region, layer, or section. Thus, a first element, component, region, layer, or section, discussed below may be termed a second element, component, region, layer, or section, without departing from the scope of this disclosure.
Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below,” “beneath,” or “under,” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein translated accordingly. In addition, when an element is referred to as being “between” two elements, the element may be the only element between the two elements, or one or more other intervening elements may be present.
As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups, thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed products. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. For example, the expression, “at least one of a, b, and c,” should be understood as including only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or any variations of the aforementioned examples. Also, the term “exemplary” is intended to refer to an example or illustration.
When an element is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to,” another element, the element may be directly on, connected to, coupled to, or adjacent to, the other element, or one or more other intervening elements may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to,” another element there are no intervening elements present.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. Terms, such as those defined in commonly used dictionaries, should be translated as having a meaning that is consistent with their meaning in the context of the relevant art and/or this disclosure, and should not be translated in an idealized or overly formal sense unless expressly so defined herein.
Example embodiments may be described with reference to acts and symbolic representations of operations (e.g., in the form of flow charts, flow diagrams, data flow diagrams, structure diagrams, block diagrams, etc.) that may be implemented in conjunction with units and/or devices discussed in more detail below. Although discussed in a particular manner, a function or operation specified in a specific block may be performed differently from the flow specified in a flowchart, flow diagram, etc. For example, functions or operations illustrated as being performed serially in two consecutive blocks may actually be performed concurrently, or in some cases be performed in reverse order.

Hereinafter, example embodiments of a method and apparatus for translating audio of a video into sign language through an avatar are described.
Herein, a video call may inclusively represent a video phone through which video and audio are exchanged between a user and a counterpart, for example, a voice over Internet protocol (VoIP) of technology for converting video and audio into a digital packet through a network using an IP address.
The example embodiments may provide a sign language translation as one of translation options on a VoIP.
The computing device 200 according to the example embodiment may provide a client with a sign language translation service through connection to a dedicated application installed on the client or a website/mobile site related to the computing device 200. A sign language translation system may be configured in the computing device 200 according to the example embodiment. For example, the sign language translation system may be implemented in an independently operating program form or may be configured in an in-app form of a specific application to be operable on the specific application.
The processor 220 of the computing device 200 may be implemented as a component for performing the following sign language translation method. Depending on example embodiments, the components of the processor 220 may be selectively included in or excluded from the processor 220. Also, depending on example embodiments, the components of the processor 220 may be separated or merged for functional representations of the processor 220.

Referring to
In operation S320, the processor 220 may set an avatar for sign language expression for each video call participant in the video call in which the sign language translation is set. The avatar may refer to a character that represents a user in a virtual environment and may include a plurality of avatar components. For example, the avatar components may include a component that defines an appearance of the avatar (e.g., an eye shape, a nose shape, a lip shape, a face shape, a body type, a hair style, etc.), a component that defines a gesture of the avatar, and a component that defines an item worn by the avatar (e.g., clothes, shoes, glasses, accessories, etc.). For example, the processor 220 may set an avatar directly selected by a corresponding participant for each video call participant. As another example, the processor 220 may automatically set a non-overlapping avatar through arbitrary settings for each video call participant. When setting an avatar for each video call participant, the processor 220 may recognize a face of each participant in a call video based on a face recognition and artificial intelligence (AI) technology and may generate and use an avatar of a character that resembles a corresponding participant.
In operation S330, the processor 220 may translate audio of a speaker into sign language during the video call. The processor 220 may convert a call audio to a text (e.g., into text data) through a speech-to-text (STT) technique in a VoIP-based video call environment. The processor 220 may convert the converted text into the sign language through an artificial intelligent (AI)-based sign language translation model.
In operation S340, the processor 220 may reproduce a motion corresponding to the sign language translated in operation S330 through an avatar of the corresponding speaker. The processor 220 may express the motion of the avatar that represents the speaker through the motion of the translated sign language. That is, the processor 220 may express a sign language sentence through conversion to preset hand gestures and gestures of other body elements.
The processor 220 may apply an avatar model capable of more naturally expressing the sign language through a lip movement, a facial expression, a complexion, an eye movement, a body movement, and the like in addition to a hand gesture that includes a hand shape, a hand direction, and a hand movement. For example, the processor 220 may apply a facial expression of a speaker extracted in a call video to an avatar model based on face detection technology.
The processor 220 may analyze an emotional state of the corresponding speaker from a spoken sentence or intonation included in the call audio and may apply information on the analyzed emotional state to a facial expression or a gesture of the avatar. In addition to the call audio, the processor 220 may analyze the call video of the speaker based on the face detection technology and may extract an emotional state revealed on a face of the speaker. When providing a sign language translation, the processor 220 may change and express other body gestures, facial expressions, gazes, and postures that may be expressed with the visual language according to an emotion of the speaker in addition to hand gestures of the sign language, through change to various actions of the avatar.
The processor 220 may receive a counterpart video for a video call from a terminal of a counterpart and may display a video call screen that includes a user video and the counterpart video. The processor 220 may configure a video call screen by receiving the counterpart video of the counterpart that participates in the video call as an individual video and then render the received counterpart video with the user video on a single screen.
Also, instead of generating a single video that includes a plurality of participant videos and providing the generated video to a client on the side of the server 150 that provides the video call service, the server 150 may transmit each participant video as an individual video, and the client may receive each of the plurality of participant videos as the individual video and may configure the received individual videos as the video call screen on the single screen.
The server 150 may mix an avatar video that expresses the sign language on one side of the call video and then transmit the same as a participant video or may transmit the call video and the avatar video as individual videos. In a former case, the client may configure the video call screen with the participant video mixed with the avatar video on one side. In a latter case, the client may configure the video call screen by combining the call video and the avatar video according to a defined layout. For example, the client may configure the call video as the video call screen on one screen and may overlay the avatar video translating the sign language on one side (e.g., at a right lower end) of the video call screen.
As an avatar of a different character is set for each video call participant, the processor 220 may provide a sign language translation through a different avatar for each speaker (that is, the avatar set for each speaker).
The processor 220 may apply a separate display element to the video call screen to easily identify the avatar and the participant providing the sign language translation among video call participants, so as to easily identify a speaker of audio that is currently being translated into the sign language.
When at least two participants concurrently speak among the video call participants, the processor 220 may allow avatars of the respective speakers to appear together and may provide a sign language translation for each speaker.
The sign language translation service according to the example embodiment may include a function of translating audio of a speaker into sign language during a video call, as well as a function of recognizing a body gesture of a participant that appears in a call video and providing the recognized body gesture using text or audio. That is, the sign language translation service may translate the sign language (e.g., of a video using captions) by converting the sign language into text based on AI and video recognition technology, or may translate the sign language using audio through a TTS technique.
Referring to
A user may set the sign language translation for call audio of the user using the “sign language translation” menu 401 prior to participating in the video call.
Referring to
The processor 220 may configure the video call screen 500 by receiving the counterpart video 520 of each participant that participates in the video call as an individual video and by rendering the received counterpart videos 520 with the user video 510 on a single screen.
Referring to
The server 150 may transmit a call video of each participant as an individual video and may also provide a video of the avatar 650 providing the sign language translation. The processor 220 may display the video of the avatar 650 to be overlaid on the video call screen 500 on which the user video 510 and the counterpart video 520 are rendered on a single screen.
The processor 220 may display which avatar among the avatars of video call participants (or which call participant in embodiments were the counterpart videos 520 are not using avatars) corresponds to the avatar 650. That is, the processor 220 may identify, via a visual effect, a speaker of audio that is currently being translated into the sign language such that the speaker of the audio is distinguished from other participants through a separate display element 651 on the video call screen 500.
Although

That is, the processor 220 may provide the sign language translation through the respective different avatars 650 and 760 according to the respective corresponding speakers, such that the speakers may be easily distinguished from each other.
Referring to
Referring to
For example, when user A 950 and user B 951 concurrently speak, the processor 220 may apply a solid line outline to a call video and an avatar of user A 950 and may apply a dashed line outline to a call video and an avatar of user B 951. In other embodiments, the processor 220 may apply color effects, video effects or other effects such that a visual effect that is applied to a counterpart video being displayed corresponds to a visual effect that is applied to the avatar (and/or the avatar video being displayed). Therefore, a sign language translation for audio spoken by each of user A 950 and user B 951 may be easily identified and recognized.
When an avatar 1050 corresponding to a speaker appears on the video call screen 500 and, in response thereto, the processor 220 provides a sign language translation for audio of the corresponding speaker, the processor 220 may analyze a current emotional state of the speaker from a call video of the speaker, a sentence or intonation of the speaker, and the like, and may apply information on the analyzed emotional state to a facial expression or a gesture of the avatar 1050.
Referring to
The processor 220 may translate call audio into sign language and may also translate the sign language of a call video into text or audio during a video call.
Referring to
The processor 220 may provide a translation result for sign language of a video as the text caption 1100 and may also provide the translation result in a form of audio through TTS.
Although the example embodiments are described to provide a sign language translation service during a video call, it is provided as an example only and the sign language translation service may be applied to any video-based service capable of delivering visual information. For example, in a video platform that shares video content, audio of a character that appears in a video may be translated into sign language using an avatar during playback of the video. By setting an avatar of a different character for each character, audio of a corresponding character may be translated into sign language through an avatar of the corresponding character.
According to some example embodiments, to the system may translate audio of a video into sign language in real time using an avatar during a video call. According to some example embodiments, to the system or user may easily identify a speaking entity by providing sign language through an avatar of each speaker. According to some example embodiments, the system may analyze emotion of a speaker from a call video or a call audio and apply the analyzed emotion to a facial expression of an avatar that provides the sign language translation.
The apparatuses described above may be implemented using hardware components, software components, and/or a combination thereof. For example, the apparatuses and components described herein may be implemented using one or more general-purpose or special purpose computers, for example, a processor, a controller, an ALU, a digital signal processor, a microcomputer, a FPGA, a programmable logic unit (PLU), a microprocessor, or any other device capable of responding to and executing instructions in a defined manner. A processing device may run an OS and one or more software applications that run on the OS. The processing device also may access, store, manipulate, process, and create data in response to execution of the software. For simplicity, the description of a processing device is used as singular; however, one skilled in the art will be appreciated that the processing device may include multiple processing elements and/or multiple types of processing elements. For example, the processing device may include multiple processors or a processor and a controller. In addition, different processing configurations are possible, such as parallel processors.
The software may include a computer program, a piece of code, an instruction, or some combinations thereof, for independently or collectively instructing or configuring the processing device to operate as desired. Software and/or data may be embodied in any type of machine, component, physical equipment, a computer storage medium or device, or in a propagated signal wave capable of providing instructions or data to or being interpreted by the processing device. The software also may be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. The software and data may be stored by one or more computer readable storage mediums.
The methods according to some example embodiments may be configured in a form of program instructions performed through various computer methods and recorded in non-transitory computer-readable media. The media may include, alone or in combination with program instructions, data files, data structures, and the like. The media may continuously store computer-executable programs or may temporarily store the same for execution or download. Also, the media may be various types of recording devices or storage devices in a form in which one or a plurality of hardware components are combined. Without being limited to media directly connected to a computer system, the media may be distributed over the network. Examples of the media include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical media such as CD-ROM and DVDs; magneto-optical media such as floptical disks; and hardware devices that are specially configured to store and perform program instructions, such as ROM, RAM, flash memory, and the like. Examples of other media may include recording media and storage media managed by an app store that distributes applications or a site, a server, and the like that supplies and distributes other various types of software.
The foregoing embodiments are merely examples and are not to be construed as limiting. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
