Computer intelligent recognition and studied of the pronunciation of Xiahe dialect database system through speech aerodynamics

This paper takes Xiahe dialect of Tibetan Amdo as the research object, and there is a special linguistic phenomenon in Xiahe dialect-compound consonants. The paper sorted out the compound consonant system of Xiahe dialect and showed the air flow waveform of different compound consonants. According to the analysis of the air flow parameters of different pre consonant pronunciation, it is concluded that the clarity of pre consonant has a certain impact on the pronunciation duration and average air flow speed.
