Outbound calls are now visible in the Call History page. - **Automatic language detection**: Added new system tool for automatic language detection that enables agents to switch languages based on both explicit user requests ("Let's talk in Spanish") and implicit language in user audio. - **Pronunciation dictionary improvements**: Fixed phoneme tags in pronunciation dictionaries to work correctly with Agents Platform. - **Large RAG document viewing**: Added ability to view the entire content of large RAG documents in the knowledge base. - **Customizable widget controls**: Updated UI to include an optional mute microphone button and made widget icons customizable via slots. ### Sound Effects - **Fractional duration support**: Fixed an issue where users couldn't enter fractional values (like 0.5 seconds) for sound effect generation duration. ### Speech to Text - **Repetition handling**: Improved detection and handling of repetitions in speech-to-text processing. ### ElevenCreative Studio - **Reader publishing fixes**: Added support for mp3_44100_192 output format (high quality) so users below Publisher tier can export audio to Reader. ### Mobile - **Core app signup**: Added signup endpoints for the new Core mobile app. ### API ## New Endpoints - Added 5 new endpoints: - [List voices (v2)](/docs/api-reference/voices/search) - Enhanced voice search capabilities with additional filtering options -
