Changelog

Forced Aligment

• Forced alignment improvements: Fixed a rare failure case in forced alignment processing to improve reliability.

Voices

• Live moderated voices filter: Added include_live_moderated query parameter to the shared voices endpoint, allowing you to include or exclude voices that are live moderated.

Conversational AI

• Secret dynamic variables: Added support for specifying dynamic variables as secrets with the secret__ prefix. Secret dynamic variables can only be used in webhook tool headers and are never sent to an LLM, enhancing security for sensitive data. Learn more.
• Skip turn system tool: Introduced a new system tool called skip_turn. When enabled, the agent will skip its turn if the user explicitly indicates they need a moment to think or perform an action (e.g., “just a sec”, “give me a minute”). This prevents turn timeout from being triggered during intentional user pauses. See the skip turn tool docs for more information.
• Text input support: Added text input support in websocket connections via “user_message” event with text field. Also added “user_activity” event support to indicate typing or other UI activity, improving agent turn-taking when there’s interleaved text and audio input.
• RAG chunk limit: Added ability to configure the maximum number of chunks collected during RAG retrieval, giving users more control over context window usage and costs.
• Enhanced widget configuration: Expanded widget customization options to include text input and text only mode.
• LLM usage calculator: Introduced tools to calculate expected LLM token usage and costs for agents, helping with cost estimation and planning.

Audio Native

• Accessibility improvements: Enhanced accessibility for the AudioNative player with multiple improvements:
  • Added aria-labels for all buttons
  • Enabled keyboard navigation for all interactive elements
  • Made progress bar handle focusable and keyboard-accessible
  • Improved focus indicator visibility for better screen reader compatibility
