### Answer There isn't a single "best" setting—it depends on your use case. Here's what each setting does: Responsiveness (

responsiveness

) : Value ranging from [0,1]. Lower value means less responsive agent (wait more, respond slower) , while higher value means faster exchanges (respond when it can) . If unset, default value 1 will apply. [(1) ]() Interruption Sensitivity (

interruption_sensitivity

) : Value ranging from [0,1]. Lower value means it will take longer / more words for user to interrupt agent, while higher value means it's easier for user to interrupt agent. If unset, default value 1 will apply. When this is set to 0, agent would never be interrupted. Recommendations based on your scenario: - **Reducing responsiveness by 0.1 adds 0.5 seconds of agent wait time**—useful when talking to folks like elderly. [(2) ]() - Lower interruption sensitivity makes the agent more resilient to background speech or user interruptions. - For noisy environments, community members suggest lowering interruption sensitivity and adding prompt instructions to handle interruptions gracefully. [(3) ]() Your current settings (responsiveness: 1, interruption sensitivity: 0.9) are close to defaults and work well for fast, natural conversations. If you're experiencing issues with background noise triggering interruptions, try lowering

interruption_sensitivity

(e.g., 0.5–0.7) .

### Answer The default values for those settings are: - **Responsiveness**:

1

(if unset, default value 1 will apply) [(1) ]() - **Interruption Sensitivity**:

1

(if unset, default value 1 will apply) So both default to

1

, which means fast exchanges and easy interruption by the user.
