Transcriptions resource

(warning)

Warning

The Recording Transcriptions API is deprecated. For new transcription workflows, use the Batch Transcription API.

On this reference page, you'll learn the properties, methods, and parameters for the Transcriptions resource. See Related how-to documentation to learn the steps to use the info on this page.

A Transcription resource 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)

PCI compliance

Call recordings aren't Payment Card Industry (PCI) compliant by default. To use Voice Recordings in a PCI workflow, enable PCI Mode in the Twilio Console(link takes you to an external page).

To transcribe voice recordings, use the <Transcription> TwiML noun. Native and Marketplace 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(link takes you to an external 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:

1
curl -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:

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

    2
      -u $TWILIO_ACCOUNT_SID:$TWILIO_AUTH_TOKEN
