Example Embodiment

[0013] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0014] figure 1 It is a schematic diagram of the structure of the present invention. As shown in the figure, the method of the present invention is mainly completed by the speech recognition module 1, the subtitle processing module 2 and the image synthesis module 3.

[0015] Preferably, the following two methods can be used to display subtitles:

[0016] Method 1: If the storage area on the subtitle processing module is updated, the image synthesis module is notified to perform image superposition, and then the superimposed image data is coded, transmitted, and displayed. When the number of words in the subtitle display area meets the subtitle setting requirements, the display area is cleared and the storage area is updated. If the storage area is not updated after the update time is reached, the subtitle display area will also be cleared, waiting for ...

Abstract

The invention relates to a method for displaying captions synchronously in a video call process. The method is mainly realized by a voice recognition module, a caption processing module and an image synthesis module. In the video call process, the captions are generated by applying the voice recognition technology, and then the captions are superposed on a local terminal image according to caption display rules preset by a user and transmitted to a remote terminal user after processing. The increase of the caption display in the video call process is important compensation to the video call, and can improve the video call quality and enhance the communication effect. In addition, the captions generated by utilizing the method can be displayed on mobile phones supporting the video telephone function without increasing software procedures or hardware devices, thus being convenient and practical.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular, the invention relates to a method for synchronously displaying subtitles in a video phone. The user using the invention can convert the sound information into subtitle data without affecting the normal conversation, superimpose it with the image at the local end, and then send it to the remote user. Background technique [0002] With the development of mobile communication technology, the video phone service has been rapidly promoted by virtue of its vivid and intuitive user experience. The current video telephony function mainly achieves the purpose of information exchange by collecting the video and audio data of both parties in the call and transmitting them according to the agreed protocol. However, during the current video call, the communication method mainly relies on verbal expression. When the voice transmission is not clear, it will inevitably affect the call quality ...
