From WirelessWeek.com

The value of voice is rarely assessed and certainly, from a telephony perspective, voice is as commoditized as tapwater. However, the ability to use voice as a biometric signature may be coming of age, particularly as we are on the cusp of a whole host of mobile transaction services where authentication of the end user will be paramount.

To date, voice biometric deployments aren't very common. There are, however, many types of transactions in the health care and financial sectors where voice is the only biometric available.
