Method and system for recognizing a boundary between contiguous sounds for use with a speech recognition system
First Claim
Patent Images
1. In a speech recognition system, a method for recognizing a boundary between two contiguous spoken sounds, the method comprising the steps of:
- defining a delimitative spoken sound which represents the boundary;
receiving continuously spoken speech that includes the delimitative spoken sound;
extracting at least one feature from the continuously spoken speech corresponding to the delimitative spoken sound; and
recognizing the boundary by classifying the at least one feature according to a polynomial discriminant function.

Abstract
Boundaries of spoken sounds in continuous speech are identified by classifying delimitative sounds to provide improved performance in a speech-recognition system. Delimitative sounds, those portions of continuous speech that occur between two spoken sounds, are recognized by the same method used to recognize spoken sounds. Recognition of delimitative sounds is accomplished by training a learning machine to act as a classifier which implements a discriminant function based on a polynomial expansion.
