Automatic speech recognition (ASR) technology enables a computer to identify spoken words, thereby receiving data input from a user. When applied to computer telephony, ASR enables a computer to recognize speaker-independent commands from a telephone for navigation through an automated Interactive Voice Response (IVR) system and to use the communication as data input.
When the audio input arrives, the speech recognition engine processes the input against a grammar (a collection of pre-defined words or phrases), translates it, and passes text to the application. Different grammars can be used during the call flow.
Within VBVoice, you enable ASR through a control that routes call-flow when a command is recognized. No-Match routing is also built-in. VBVoice can provide speech recognition on multiple lines simultaneously.
VBVoice supports speech recognition using sophisticated, third party technologies from Nuance.
