Here is an explanation of the functions you mentioned: • _cancel_user_away_timer: Cancels a timer that would set the user's state to "away" after inactivity. It ensures the user state remains accurate when activity resumes, such as when the user starts speaking again. • _user_speaking_span: Tracks the duration of the user's speaking activity using telemetry. It provides detailed timing information for monitoring and debugging voice interactions. • _update_agent_state(self, state: AgentState) -> None: Updates the agent's state, manages transitions, resets error counters, handles tracing spans, and emits events for state changes. It also interacts with the user state to manage "away" timers. These functions are primarily designed for managing user and agent states, as well as tracking activity. If you are looking to implement an idle speech function, these could be relevant depending on your specific requirements. Could you clarify what you mean by "idle speech function" and how you intend to use these?
