of the least studied languages on speech recognition area. In this work, we present the research process of Uyghur Large Vocabulary Continuous Speech Recognition based on HMM (Hidden Markov Model). This paper introduce the process of data collection (text corpus and speech corpus), the unit selection for speech recognition, the creation of acoustic and language model for Uyghur language. Also presents the experimental results of Uyghur continuous speech recognition in different recognition units. KeywordsUyghur; speech recognition; acoustic model; language model; recognition unit
