Feasibility Study Using Chinese Speech as a Command/Control Tool for Computer Systems

摘要

This thesis examined whether American English speech recognition technology can be used by Chinese speakers, in their native tongue, to achieve a reasonable degree of recognition accuracy. Three experiments were completed. The first showed that 88.25% of 4305 trials of Chinese phoneme recognition was correctly recognized. The second showed that 74.67% of 900 trials of simulated speaker independent model Chinese phoneme recognition was correctly recognized. The third showed that 12.44% of 900 trials of speaker dependent mode Chinese utterance recognition was incorrectly recognized on the first attempt. Only 16 utterances required a retraining to eventually obtain a correct recognition. Keywords: Chinese language speech recognition; Voice recognition; Chinese phonetic system. (Theses)
