Voice AI Adds Noise Cancellation and Backchanneling Settings

TL;DR

HighLevel added noise cancellation, customizable backchanneling, and interruption sensitivity to Voice AI agents. Review your Voice AI configurations if you run conversational agents on live calls.

Who this affects

HighLevel has not confirmed specific plan gating or sub-account restrictions for these features. Agencies building and deploying Voice AI agents should pay attention, while teams not using Voice AI can safely skip this update.

What changed

HighLevel introduced several conversational audio settings for Voice AI agents:

• Voice AI agents now support backchanneling to play spoken affirmations during live calls.
• Users can configure the specific backchanneling affirmation phrases and how frequently they trigger.
• Voice AI agents now support noise cancellation to filter out caller background noise and secondary voices.
• Users can adjust interruption sensitivity settings directly in the agent configuration.

HighLevel has not confirmed rollout status, plan limits, or whether any existing agent behavior is replaced or broken.

Where to find it

Navigate to AI Agents > Advanced Settings inside your HighLevel account.

How agencies will use this

An agency setting up an inbound Voice AI agent inside a client sub-account can open AI Agents > Advanced Settings to refine call handling.

By turning on noise cancellation, the agent can filter out ambient noise and secondary background voices when a caller reaches out from a noisy location.

To make interactions feel less rigid, the agency can set specific spoken affirmation phrases and adjust their frequency, along with calibrating interruption sensitivity so the agent does not inappropriately cut off the caller.

Our take

This is a standard update, but a practical one.

Voice AI often struggles with caller interruptions and background audio. Giving operators direct control over affirmation frequency, noise cancellation, and interruption thresholds fixes clear operational annoyances. If you already use Voice AI, test the new toggles in Advanced Settings. If you do not run Voice AI agents, this does not affect your operations.
