- Add EnableInterruptionsFrame custom frame for pipeline-based control
- Subclass VADUserTurnStartStrategy as DynamicVADUserTurnStartStrategy
- Use task.queue_frame() to toggle interruptions idiomatically
- Follows same pattern as MixerEnableFrame in 23-bot-background-sound.py
This example shows how to disable interruptions while still transcribing
user speech using the enable_interruptions parameter on user turn start
strategies (introduced in 0.0.99).
Key features demonstrated:
- VADUserTurnStartStrategy and TranscriptionUserTurnStartStrategy with
enable_interruptions=False to prevent bot interruption
- Dynamic toggling via user_turn_controller.update_strategies() at runtime
- Transcription continues in both modes, only interruption behavior changes
