Authenticate callers with their voice

Authenticating callers with security questions is not only unsafe, it is costly, time-consuming, frustrating for your customers AND for your agents. There is a much better way.

You can authenticate your callers seamlessly and transparently with their voice while they are talking with your agents on the phone. Here’s how it works:​

  • The first time customers call, the voice biometrics system creates a voiceprint based on the caller’s voice pattern while they’re talking with the agent. This all happens in the background.
  • Once the voiceprint is created, the agent asks the caller if they agree to be identified with their voice the next time they call.
  • The next time they call, customers are transparently authenticated within the first few seconds of their conversation with the agent.

“Before voice biometrics, fraudsters repeatedly broke into customer’s accounts, every day. The contact center was the weakest link and fraudsters took advantage of it.”
