Upgraded Babel Model + Language Locking

We’ve rolled out an upgrade to Babel, our in-house transcription engine—along with new language-locked variants for improved accuracy.

  • Babel becomes more accurate over the course of the call using contextual speech refinement
  • New API options support locked languages like English, Spanish, French, and more (e.g. babel-en, babel-es, babel-fr)
  • Language locking improves recognition accuracy by removing the need for auto-detection
  • Low-confidence audio is now marked with [inaudible], allowing your agent to respond or prompt naturally

If your callers consistently speak the same language, we recommend trying a locked-language model for higher transcription quality.

OIDC SSO Support (Enterprise)

We now support OIDC-based Single Sign-On for enterprise organizations.

  • A new SSO tab is available in org settings for configuring OIDC providers
  • The login flow has been updated to handle OIDC callback
  • Works with identity platforms like Okta, Azure AD, and Google Workspace

​
Voice Chat in Web Widget

You can now enable voice input directly in the web chat widget—bringing the full conversational AI experience to the browser.

  • Users can now talk with your agents, using the same speech pipeline as our phone calls.
  • Perfect for embedded flows that need a faster, more natural interface
  • Voice configuration available as an option in widget configuration
  • Track all voice interactions through the Call Logs dashboard within Bland
