For AI agents: a documentation index is available at the root level at /llms.txt and /llms-full.txt. Append /llms.txt to any URL for a page-level index, or .md for the markdown version of any page.
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.
Agents Platform
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.
