Abstract
A continuous speech recognition and voice response system provides a natural sounding and effective interactive, speech-driven dialogue from a data processing system. A concatenation of words into phrases and sentences improves recognition and mimic natural language processing. The system uses speaker-independent, continuous-speech to initiate the playback of audio files. The system employs high-speed context switching to modify the active vocabulary and applies high-speed context switching to modify or activate Audio WAV voice response files. The system uses dialogue history to activate selected context, Baukus-Naur Form (BNF) grammars and WAV files and provides phrase or sentence long dialogue prompts to improve accuracy. The system also provides audio prompts to improve accuracy and provides speech-activated buttons to navigate between menus.
