Event Based System: A Probabilistic Acoustic-Phonetic Approach to Automatic Speech Recognition (ISR IP)

ISR intellectual property available to license

Inventors: Carol Espy-Wilson, Amit Juneja

Description
The state of the art voice recognition systems use very little knowledge of acoustic-phonetics and are largely dependent on statistical modeling.

This invention, deemed a substantial advancement in the art, brings together knowledge of acoustic-phonetics and statistical pattern recognition to build a system, called Event-Based System (EBS) for automatic speech recognition. The system is based on representation of speech sounds by bundles of binary valued phonetic features.

This system not only obtains better accuracy in identification but also, unlike other systems, does not require initial training to 'learn" to recognize.
