Abstract

The embodiment of the invention provides a method and a device for displaying live broadcast subtitles, a server and a medium, and relates to the technical field of information processing. The methodaccording to the embodiment comprises the steps of receiving a live broadcast task instruction sent by a live broadcast management system, receiving and caching audio data and video frame data sent bythe live broadcast management system based on the live broadcast task instruction, performing voice recognition on the audio data; text data corresponding to the audio data is obtained; and accordingto the timestamp of the text data and the timestamp of the video frame data, superposing the text data to the video frame data with the same timestamp as the text data to obtain the video frame datacarrying the subtitle information, and outputting a media stream composed of the video frame data carrying the subtitle information and the audio data. By adopting the method, subtitles can be displayed for the live video.
