AllThingsD got a demo of the [Dragon Naturally Speaking] technology last week. It basically brings together what Nuance does well: Speech recognition, text-to-speech, natural-language understanding and voice-ID biometric technology. It has rolled all of these into a hosted, cloud-based service that can be used by banks, insurance companies and other business who make customer service and account-access applications, which can now add all these features into their applications.
Voice Recognition is a behavioral biometric modality that is used to distinguish among individuals for identity management purposes.
Speech Recognition is a software set designed to allow users to interact with IT hardware and systems by speaking.
An app that can do both well at a reasonable price should do quite well in the market. USAA is an early adopter
