AI Voice Agent Advanced Settings
Advanced settings control how your AI Voice Agent handles timing, interruptions, background noise, and call limits. These settings fine-tune the caller experience beyond what behavior and call flow cover.
Available on: All AI Voice Agent plans.
Responsiveness
Controls how quickly the agent responds after the caller finishes speaking.
| Level | Effect |
|---|---|
| Low | Deliberate pauses between responses — feels thoughtful and measured |
| Medium | Balanced response timing — the default |
| High | Fast, conversational tempo — feels like talking to a live person |
Start with Medium and adjust based on transcript review. High responsiveness works well for quick-answer scenarios (appointment confirmations, hours of operation). Low responsiveness works better for complex conversations where callers need time to process.
Interruption Sensitivity
Controls how the agent reacts when a caller talks over it.
- Low sensitivity — the agent finishes its sentence before yielding. Use when the agent frequently gets cut off by background noise or filler words ("uh huh," "yeah").
- High sensitivity — the agent stops immediately when it detects speech. Use for fast-paced conversations where callers expect to interrupt naturally.
Tip: If callers complain the agent talks over them, increase sensitivity. If the agent stops mid-sentence too often, decrease it.
Background Sound
Add ambient audio to make the call feel more natural:
| Sound | Effect |
|---|---|
| Coffee shop | Soft background chatter and ambient noise |
| Call center | Light office sounds — typing, distant conversation |
| Outdoor | Wind and environmental sounds |
| None | Clean, silent background (default) |
Background sound is subtle — it sits behind the agent's voice. It can reduce the "talking to a computer" feeling, especially for customers unfamiliar with AI agents.
Voicemail Detection
When enabled, the agent detects answering machines and voicemail on outbound calls.
Options:
- Hang up — end the call immediately when voicemail is detected
- Leave a message — deliver a configurable voicemail message
Use this setting to avoid wasting AI minutes on voicemail systems during outbound campaigns.
End Call on Silence
Automatically ends the call after a period of sustained silence.
Set the silence threshold (e.g., 15 seconds, 30 seconds). If neither the agent nor the caller speaks for the configured duration, the call ends with a polite closing message.
This prevents abandoned calls from consuming AI minutes and keeps the agent available for the next caller.
Maximum Call Duration
Set a hard time limit for calls. When the limit is reached, the agent delivers a closing message and ends the call.
Use cases:
- Free consultations capped at 15 minutes
- Initial qualification calls limited to 5 minutes before transfer
- General safety limit to prevent runaway conversations
The agent warns the caller before the limit is reached and offers to transfer or schedule a follow-up.
