Hi xjlv1113,

Main purpose is to prevent listening itself, when it's giving the audio output.

How is it being used in different scenarios:

• When the system is listening and processing user input, should_listen is set to True.
• When the system detects the end of user speech (in VADHandler), it sets should_listen to False, preventing further input processing.
• While the system is generating and outputting its response (in TTS Handler files), should_listen remains False.
• After the system finishes speaking, it sets should_listen back to True, allowing it to process the next user input.

Exactly! Without the 'should_listen', the model would listen to itself and begin talking to itself (unless you're wearing headphones). I guess there's a way to improve that but both I and @eustlb looked into it individually and weren't happy with the solutions we found.
