Pitch determiner for a speech analyzer
First Claim
1. A pitch determiner for use with a speech analyzer for determining a pitch within one or more sequential segments of speech, each segment of speech being represented by a predetermined number of digitized speech samples, said pitch determiner comprising:
- a pitch function generator for generating from the predetermined number of digitized speech samples, a plurality of pitch components representing a pitch function, wherein said pitch function defines an amplitude of each of the plurality of pitch components;
a pitch enhancer, for enhancing the pitch function of a current segment of speech utilizing the pitch function of one or more sequential segments of speech, by generating a plurality of enhanced pitch components; and
a pitch detector for detecting the pitch of the current segment of speech by determining the pitch of an enhanced pitch component having a largest amplitude of the plurality of enhanced pitch components.

Abstract
A pitch determiner (414) for use with a speech analyzer includes a pitch function generator (414) which generates a plurality of pitch components representing a pitch function for one or more sequential segments of speech. which are represented by a predetermined number of digitized speech samples. A pitch enhancer (1116) enhances the pitch function of a current segment of speech utilizing the pitch function of one or more sequential segments of speech to generate a plurality of enhanced pitch components. A pitch detector (1118) detects the pitch of the current segment of speech by determining the pitch of an enhanced pitch component having a largest amplitude of the plurality of enhanced pitch components.
