(information)

Info

Public Beta

Voice Intelligence is currently available as a public beta release. Some features are not yet implemented and others may be changed before the product is declared as Generally Available. Beta products are not covered by a Twilio SLA.

General Limitations and Caveats

general-limitations-and-caveats page anchor
  • As a Public Beta product, Voice Intelligence is currently not included within Twilio's helper libraries. You will need to make requests directly against the API while the product is in Public Beta.
  • Voice Intelligence is not PCI or HIPAA compliant.
  • Encrypted recordings are not supported.

Transcripts App

transcripts-app page anchor
  • In past pre-release documentation, the Transcripts App was called Discovery. The old name is still used in some places, such as app retrieval URLs.
  • Transcripts are indexed and available for search for 90 days.
  • Search terms are linked with the OR operator. For example, macaroni salad will match transcripts that have macaroni OR salad ).

Transcription

  • PII redaction is only available in en-US .

  • The following limitations apply when fetching media stored in a third-party location (specified by a MediaUrl).

    • Currently, Voice Intelligence does not send an X-Twilio-Signature header for media fetch requests. As a result, media stored in Twilio Assets needs to be made public.
    • If you use external recordings, Basic authentication on MediaUrl s is not supported. If you store the recordings on S3, use a presigned URL(link takes you to an external page) . And when storing them on Azure Blob Storage, use a Shared Access Signature (SAS)(link takes you to an external page) .
    • MediaUrl s that respond with a HTTP status code that is not a 200 will result in a transcription request that does not complete.
    • Requests to fetch third-party media are performed exactly once. There is currently no retry behavior.
  • Voice Intelligence does not perform speaker diarization on recordings. The use of mono recordings will result in lower transcription accuracy.
  • Recordings that are under two seconds in length are not transcribed.
  • Only up to two Participants can be overridden in the Channel object of the Transcript resource.
  • Voice Intelligence will only process recordings or 3rd party media that are under 1GB.
