Abstract：Pinyin-to-Character conversion is an important task in Chinese Information Processing with widely applications in such tasks as Chinese Speech Recognition, Chinese Pinyin input method et al. This paper investigates the Pinyin-to-Character conversion and the segmentation of pinyin stream and proposes a method using Language Model to improve pinyin stream segmentation model. This method achieves about 3% enhancement in precision of the first character compared to the traditional hierarchical model. Key wordsartifical intelligence; natural language processing; pinyin-to-character conversion; hidden markov model; Chinese information processing; segmentation ambiguity
