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

Improvements

  • You can now configure a “Go to Node” action inside the Press Button Node
  • Adds isRetry: true support in post call webhooks to determine if the call was retried
  • Improved JSON validation when uploading conversational pathways to an organization
  • Fixes test case issues affecting test coverage stability
  • Fixes bug where if proxy agent presses button, primary call would go into end state (leave voicemail, or go to a node)
  • Fixes a bug in pathway duplication logic
  • Adds version tracking to pathway editor, so when a customer updates an old system of a pathway, it will error:

This pathway was updated elsewhere. Please refresh the page to get the latest changes.

  • Fixes a crash that could occur when referencing undefined variables in execution
