Recording Transcription

A Transcription represents the transcribed text and metadata from a transcribed recording of a voice call.

The transcription text itself is the result of converting an audio recording to readable text. To generate transcriptions from call recordings, use the TwiML <Record> verb and set transcribe="true". Note that

(information)

Payment Card Industry Compliance

Call recordings are not PCI compliant by default. To make them compliant, you need to enable PCI Mode in your Twilio Voice Settings.

Note that transcriptions aren't available when PCI mode is enabled.

Warning

Your account will be charged if you request transcription for a recording, as this is a paid feature. Additionally, transcription is currently limited to recordings initiated with the TwiML <Record> verb and are at most two minutes in length.

You can also access a full list of Transcriptions directly from a given Recording by passing the RecordingSid to the Recording resource:

1/2010-04-01/Accounts/{YourAccountSid}/Recordings/{RecordingSid}/Transcriptions.json
2

The cURL command to fetch Transcriptions from a Recording looks like this:

1curl -G https://api.twilio.com/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Recordings/REXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Transcriptions.json \
2-u 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:your_auth_token'

If you prefer that Twilio responds with XML, change .json to .xml.
