Abstract: Embodiments relate to generation of timed text in web video. In an embodiment, a computer-implemented method generates timed text for online video. In the method, a request to play a timed text track of a video incorporated into a web video service is received from a client computing device. Prior to receipt of the request, audio of the video is processed to determine intermediate timed text data. The intermediate timed text data lacks a complete text transcription of the audio, but includes data to enable the complete text transcription to be generated when playing the video. In response to receipt of the request, a text transcription of the audio is determined using the intermediate data with an automated speech-to-text algorithm. Finally, the text transcription of the audio is sent to the client computing device for display along with the video.
