Since Voice Authentication Takes Approx 10 secs for Successful Authentication, is it not a Slow Process?

The usual customer authentication by a live help desk agent needs nearly 90 seconds. The first 40 secs are spent choosing the IVRS options or problem description, later 40-50 secs on quoting the relevant PIN/date of birth/answers to secret questions.

This is when a customer calls into a contact center and seeks help through the contact center executive. Instead, if we deploy the Voice Authentication, the authentication is completed in 10 secs and allows for faster resolution. This increases customer satisfaction rates and reduces AHT (Average Handling Time)/contact center billing costs
