System and method for cantonese speech recognition using an optimized phone set

A system for performing a Cantonese 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 Cantonese language without utilizing corresponding tonal information as part of different phones in said optimized phone set, said input speech data including a syllable-final/midphrase context in which a stop is located at an end of a word in a middle of a phrase, said optimized phone set responsively utilizing an appropriate consonant phone “P”, “t”, or “k” in said syllable-final/midphrase context to represent a corresponding consonant and a preceding closure;
• and
• a processor configured to control said recognizer to thereby perform said Cantonese speech recognition procedure.

• and
• a processor configured to control said recognizer to thereby perform said Cantonese speech recognition procedure.
