Customer voice change detection alerts agents when an unexpected voice change is identified on the customer side during a Voice Translation call. While Voice Translation is active, the translated audio can mask the customer's original voice, which makes it harder for agents to notice when a different person takes over the line. This feature flags that change so agents can re-verify who they are speaking with before sharing any sensitive information.
Info
Customer voice change detection works only on calls that use Voice Translation.
Enable customer voice change detection
Customer voice change detection is turned on by an Admin and applies to your whole team.
- In the Admin Portal, go to Settings >>> Team settings >>> Products >>> Voice security
- Turn on Customer voice change detection.
- Optionally, select Whisper on speaker change to play a short audio notice in the agent's ear when a new customer voice is detected. Only the agent hears it, the customer is not affected.
What agents see during a call
When an unexpected voice change is detected on the customer side, a notification appears at the top of the Voice Translation panel. If Whisper on speaker change is enabled, agents also hear a short audio notice at the same time.
- New person detected: shown when the customer's voice changes and may belong to a different speaker.
- Back to person N: shown when an earlier speaker's voice returns (for example, Back to person 1).
Important
Treat a New person detected alert as a prompt to re-confirm who is on the line. Verify the speaker's identity before continuing to share account details or any other sensitive information.
