This page documents updates to Real-Time SaaS including details of new and updated features, bug fixes, known issues, and deprecated functionality.

2023-03-02

The following changes have been released to on-demand users and are coming soon to enterprise customers:

• Major accuracy gains for English transcription (Standard and Enhanced operating points)
• Major improvement to Speaker Diarization accuracy for English (Standard and Enhanced operating points)
• Improved numeral formatting in English
• Improved formatting for common telephone numbers, measurements, websites, email addresses and credit cards
• Alphanumerics now have upper-case letters

2023-02-13

• Improved error handling for the WebSocket handshake when starting a session:
  • Previously, errors such as failed authentication or exceeded quota were communicated through a HTTP error response to the client. Now, only malformed handshake GET requests will result in a HTTP error response (400 Bad Request or 405 Method Not Allowed). Otherwise, the client will receive a 101 Switching Protocols HTTP response and any errors will be communicated by an in-band WebSocket error message followed by a WebSocket close handshake message. This enables browser clients to understand the cause of handshake errors which was previously not possible from a HTTP response. Please see the Real-Time API reference for full details of the WebSocket call flow and possible errors.
• New error message types: quota_exceeded and timelimit_exceeded
• Improved RT SaaS server timeout behaviour:
  • The server will keep a session alive for at least 60 seconds if no messages are received from the client. Previously, sessions were closed after 20 seconds of inactivity. We recommend that clients use a ping interval of 20 to 60 seconds.
