System and method for Mandarin Chinese speech recognition using an optimized phone set
First Claim
1. A system for performing a Mandarin Chinese speech recognition procedure with an electronic device, comprising:
- a recognizer configured to compare input speech data to phone strings from a vocabulary dictionary to thereby generate and output one or more recognized words from said vocabulary dictionary, said vocabulary dictionary being implemented according to an optimized phone set, said optimized phone set being implemented with a phonetic technique to separately provide consonantal phones and vocalic phones, one or more of said phone strings including more than two phones from said consonantal phones and said vocalic phones, said optimized phone set being implemented in a compact manner to include only a minimum required number of said consonantal phones and said vocalic phones, said optimized phone set representing sounds of a Mandarin Chinese language without utilizing corresponding tonal information as part of different phones in said optimized phone set, said recognizer thus performing said Mandarin Chinese speech recognition procedure without utilizing any type of tone data to thereby output said one or more recognized words as a final speech recognition result; and
a processor configured to control said recognizer to thereby perform said Mandarin Chinese speech recognition procedure.

Abstract
The present invention comprises a system and method for implementing a Mandarin Chinese speech recognizer with an optimized phone set, and may include a recognizer configured to compare input speech data to phone strings from a vocabulary dictionary that is implemented according to an optimized Mandarin Chinese phone set. The optimized Mandarin Chinese phone set may be implemented with a phonetic technique to separately include consonantal phones and vocalic phones. For reasons of system efficiency, the optimized Mandarin Chinese phone set may preferably be implemented in a compact manner to include only a minimum required number of consonantal phones and vocalic phones to accurately represent Mandarin Chinese speech during the speech recognition procedure.
