If a transcript is available for an audio recording, you can use the TranscriptAlign
task to place the time location for each word in the transcript. Use this task to align subtitles to audio or video files.
The transcript does not need to match the speech data exactly. The transcript aligner can tolerate small numbers of errors in the transcript, as well as mitigating factors related to audio, such as background noise and music.
The transcript aligner can also place metadata tags in the transcript to allow you to easily identify sections. These metadata tags do not affect the alignment process. For more information, see Metadata Tag Syntax.
