 This is useful when you want to capture what the user says during bot speech

-The key mechanism is `user_turn_controller.update_strategies()` which allows

-on start strategies controls whether InterruptionFrame is emitted.
+The key mechanism is a custom frame (`EnableInterruptionsFrame`) that is queued
