  • 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.
