The Acoustic Research of Stops CV Structure Coarticulation in Amdo Tibetan Xiahe Dialect

This paper studies on the Stops CV Structure in Amdo Tibetan's Xiahe Dialect. This study uses the research methods of speech acoustics, extraction of speech formant parameters. To research the CV structure Intra-Syllable Coarticulation. The main results of the research were as follows: In Xiahe Dialect CV structure exist coarticulation effects between consonants and vowels. The consonant made a great impact on vowel, relating mainly to the place of articulation of consonants. Consonant initials also influenced by the vowel. Through the locus slope of consonant, we found that place of articulation at back of consonants were affected most, unaspirated sound is greater than the aspirated sound.
