Embodiment Construction
[0016] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as figure 1 As shown, the overall structure diagram of the voice processing system in the video call. The video call terminals are interconnected through the basic communication network (Internet, etc.). Video calls include external online servers that enhance call functions, such as online voice recognition servers and online call atmosphere servers. The division of server functions is a logical division of functions, not a physical division, that is, the online voice and video server and the online call atmosphere server may exist on the same server host.
[0018] The video call terminal is connected to the online voice and video server and the online call atmosphere server through the basic communication network, and their previous data communication is two-way. Data communication process may include necessary user authenticat...

The invention provides a speech processing system and method during a video call. Video call terminals are interconnected and intercommunicated via a basic communication network; a video call comprises an online server with an external enhancement call function; the online server with the external enhancement call function comprises an online speech-to-text conversion module and an online call atmosphere module; the online speech-to-text conversion module comprises a speech recognition unit; users communicate via the video call terminals; a local speech-to-text conversion module of a terminal or the speech recognition unit of the online speech-to-text conversion module processes opposite-party audio data, performs speech recognition, converts speech into a text, stories the text in a text-to-subtitle conversion and storage module, laminates the recognized text content into a video image of the terminal, and displays the text content; a local call atmosphere module of the terminal or the online call atmosphere module of the online server with the external enhancement call function is invoked; and according to the recognized text content, the whole call atmosphere is rendered into image and text effects, and the image and text effects are synthesized with the video image and then are displayed at the terminal in a rendering mode.
Description
technical field [0001] The invention relates to a voice processing system and method in a video call. Background technique [0002] With the advancement of technology, the way of remote communication between people has developed from letters, telegrams, and voice calls to video calls. Video telephony needs to transmit video data and audio data at the same time. Although audio and video data are compressed, the amount of data is still 1-2 orders of magnitude larger than that of pure voice communication. The requirements for video calls on the basic network and the hardware configuration of the terminal have been greatly improved. [0003] Video calls are audio and video transmissions at the same time, but technological advancements allow video calls to carry more content, improve the user experience of video calls, and increase user stickiness. Contents of the invention [0004] The purpose of the present invention is to provide a method and system for voice processing in...
