LARGE VOCABULARY QUICK LEARNING SPEECH RECOGNITION SYSTEM
First Claim
1. A speech recognition system capable of recognizing speech independent of a speaker prior to training, said system comprising:
- a context preprocessor;
operatively associated withan acoustic word classifier;
operatively associated withan acoustic model generator;
wherein said context preprocessor operating in conjunction with said acoustic word classifier are configured to classify different words of identical sound by analyzing said words in the context of several leading and trailing neighboring words;
and wherein said acoustic model generator is configured to create an initial acoustic model derived from a statistical analysis of said acoustic word.

Abstract
A speech recognition system comprising: an analog to digital converter, a time to frequency transformer, a noise filter; a context preprocessor, an acoustic word classifier, an initial acoustic model generator, a textual search module, and a trainer. The system recognizes speech initially prior to training, due to the context preprocessor classifying words of identical sound by the context of a leading and trailing neighboring group of words and by the acoustic model generator creating an initial acoustic model derived from an acoustic word statistical analysis ‘average’. Applications of the system include voice activated computer games, command and control systems and text dictation.
