    • Configurable Voice Activity Detection (VAD): Choose sensitivity levels or disable automatic VAD entirely and use new client events (activityStart, activityEnd) for manual turn control.

    • Configurable Interruption Handling: Decide whether user input should interrupt the model's response.

    • Configurable Turn Coverage: Choose whether the API processes all audio and video input continuously or only captures it when the end-user is detected speaking.

    • Configurable Media Resolution: Optimize for quality or token usage by selecting the resolution for input media.

    • Richer Output and Features

    • Expanded Voice & Language Options: Choose from two new voices and 30 new languages for audio output. The output language is now configurable within speechConfig.

    • Text Streaming: Receive text responses incrementally as they are generated, enabling faster display to the user.
