AI_TRANSCRIBE¶

Syntax¶

AI_TRANSCRIBE( <audio_file> [ , <options> ] )

Arguments¶

Required:

audio_file

A FILE type object representing an audio file. Use TO_FILE function to create a reference to your staged file.

Optional:

options

An OBJECT value containing zero or more of the following fields.

• timestamp_granularity: A string specifying the desired timestamp granularity. Possible values are:

  • "word": The file is transcribed as a series of words, each with its own timestamp.

  • "speaker": The file is transcribed as a series of conversational “turns”, each with its own timestamp and speaker label.

  If this field is not specified, the entire file is transcribed as a single segment without timestamps by default.

Returns¶

An string containing a JSON representation of the transcription result. The JSON object contains the following fields:

• "audio_duration": The total duration of the audio file in seconds.

• "text": The transcription of the complete audio file, provided when the timestamp_granularity field is not specified.

• "segments": An array of segments, provided when the timestamp_granularity field is set to "word" or "speaker". Each segment is a JSON object containing the following fields:

  • "start": The start time of the segment in seconds.

  • "end": The end time of the segment in seconds.

  • "text": The transcription text for the segment.

  • "speaker_label": The label of the speaker for the segment, provided when the timestamp_granularity field is set to speaker. Labels are of the form “SPEAKER_00”, “SPEAKER_01”, etc. and are assigned in the order speakers are detected in the audio file.
