Phonetic Variation Model Building Apparatus and Method and Phonetic Recognition System and Method Thereof
First Claim
1. A phonetic variation model building apparatus, comprising:
- a phoneme database for recording at least a standard phonetic model of a language and a plurality of non-standardized phonemes of the language;
a phonetic variation identifier for identifying a plurality of phonetic variations between the non-standardized phonemes and the standard phonetic model;
a phonetic transformation calculator for calculating a plurality of coefficients of a phonetic transformation function based on the phonetic variations and the phonetic transformation function; and
a phonetic variation model generator for generating at least a phonetic variation model based on the at least a standard phonetic model, the phonetic transformation function and the coefficients thereof.

Abstract
A phonetic variation model building apparatus, having a phoneme database for recording at least a standard phonetic model of a language and a plurality of non-standardized phonemes of the language is provided. A phonetic variation identifier identifies a plurality of phonetic variations between the non-standardized phonemes and the standard phonetic model. A phonetic transformation calculator calculates a plurality of coefficients of a phonetic transformation function based on the phonetic variations and the phonetic transformation function. A phonetic variation model generator generates at least a phonetic variation model based on the standard phonetic model, the phonetic transformation function and the coefficients thereof.
