VideoTranscribe[video]

recognizes speech in an audio track and adds it to video as a subtitle track.

Details and Options

  • VideoTranscribe performs speech-to-text on audio tracks and adds it to video as a subtitle track. It is typically used to generate closed captions for videos.
  • The following options can be given:
  • AudioTrackSelection Automaticthe audio track to transcribe
    MaskingAllinterval of interest
    MethodAutomaticthe method to use
    PerformanceGoal$PerformanceGoalaspects of performance to try to optimize
    ProgressReporting$ProgressReportingwhether to report the progress of the computation
    TargetDevice"CPU"the device on which to perform recognition
  • By default, speech in the whole signal is recognized. Use Masking->{int1,int2,…} to limit the recognition to intervals inti.
  • By default, if a method returns non-speech tokens (e.g. [applause]), they are returned in the result. Use Method{"NonSpeechReplacement"replacements} to specify different replacements. Use "NonSpeechReplacement""" to remove them.
  • VideoTranscribe uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
