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.

First Claim:
Show all 40 claims
What is claimed is:     1. In a data processing system, a method to playback context related voice response signals and display prompts, comprising the steps of:
  • storing in a first partition of a memory, a first plurality of words having a first context, each of said first plurality of words including a second plurality of phonemes;
  • storing in said first partition a third plurality of voice response words having said first context;
  • storing in a second partition of said memory, a fifth plurality of words having a second context, each of said fifth plurality of words including a sixth plurality of phonemes;
  • storing in said second partition a seventh plurality of voice response words having said second context;
  • storing in a third partition of said memory, a ninth plurality of phoneme pattern matching data units for sharing by both contexts;
  • storing a first pointer map in said memory including a first plurality of pointers, each of which points to a respective one of said second plurality of phonemes and to a respective one of said ninth plurality of pattern matching data units;
  • storing a second pointer map in said memory including a second plurality of pointers, each of which points to a respective one of said sixth plurality of phonemes and to a respective one of said ninth plurality of pattern matching data units;
  • selecting said first context and said first pointer map in response to a first input;
  • recognizing a first spoken utterance containing one of said first plurality of words and in response thereto, outputting one of said third plurality of voice response words;
  • recognizing said first spoken utterance and in response thereto, outputting one of said fourth plurality of display prompts;
  • instantaneously selecting said second context and said second pointer map in response to a second input without loading new pattern matching data units in said memory;
  • recognizing a second spoken utterance containing one of said fifth plurality of words and in response thereto, outputting one of said seventh plurality of voice response words; and
  • recognizing said second spoken utterance and in response thereto, outputting one of said eighth plurality of display prompts.
