A Survey on Chinese Speech Recognition

This paper gives a comprehensive survey of the recognition techniques that have been applied to Chinese Speech. Speech Recognition systems for multi-syllable languages such as English have been successfully constructed in the last two decades. In recent years, Chinese speech recognition has become a fast developing area of research. This paper attempts to review and summarize techniques and results and highlight the following areas: the characteristics of Chinese spoken language (especially Mandarin and Cantonese), such characteristics have significant bearing on the approaches taken for recognition; the speech recognition framework based on the bisyllabic and tonal nature of Chinese spoken language; the recognition techniques based on bi-syllabic nature; the recognition of Chinese tones; and techniques based on language processing of words and sentence hypothesis. The results of various techniques are reported, compared and commented upon. Keywords: Chinese Speech Recognition, Surveys..
