Recording Transcription

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

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

(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)

Warning

If you request recording transcription, your account incurs additional charges. Transcription is a paid feature. Twilio only transcribes recordings initiated with the TwiML <Record> verb and that have a duration no longer than two minutes in length.
To learn about pricing, see the transcriptions pricing page.

To access a full list of transcriptions from a given Recording, pass the RecordingSid to the Recording resource:

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

To fetch Transcriptions from a Recording, write a cURL command that resembles the following:

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

To return an XML-formatted response, change the end of this URI from .json to .xml.
The Recording Transcription resource doesn't support CSV and HTML formatted responses.
Requests made for CSV and HTML files return an HTTP 404 status code.

To return only the transcription text, append ".txt" to the Transcription resource's URI:

1curl -G https://api.twilio.com/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Recordings/REXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Transcriptions.txt \
2  -u $TWILIO_ACCOUNT_SID:$TWILIO_AUTH_TOKEN
