Abstract:
A Mandarin speech input method for directly translating arbitrary sentences of a Mandarin speech input into corresponding Chinese characters, comprising:acoustic processing of the arbitrary sentences of the Mandarin speech, the acoustic processing step comprising:employing ""Base Syllable Models"", formed from ""sub-syllable units"" of the Mandarin speech, based on ""Hidden Markov Models"" developed for characteristics of Mandarin mono-syllables in the Mandarin speech, and based on ""Tone Models"" developed for characteristics of tone of the Mandarin speech, to calculate probabilities of each of the mono-syllables in the Mandarin speech input for recognition; andlinguistic decoding an output of the acoustic processing step, the linguistic decoding comprising:employing ""Chinese Language Models"" to locate the corresponding Chinese characters for a sequence of the recognized mono-syllables, wherein: the Mandarin speech input comprises continuous speech, andThe ""Chinese Language Modesl"" are generated by combining statistical information, resulting from an analysis of probabilities of associativity among ""characters"", ""words"" and ""word classes"" of a Chinese language, with a linguistic knowledge or rules obtained from an analysis of parts-of-speech, syntax and semantics of the Chinese language.
