Research of Chinese Diphthongs Pronunciation Based on DIVA Model

doi:10.16182/j.issn1004731x.joss.201702004

Abstract

Abstract: DIVA (Directions Into Velocities of Articulators) is a kind of adaptive neural network model which is used to simulate and describe some associative functions in brain regions involved speech production and understanding. DIVA takes 29 essential English phonemes as its language background. Since the number of Chinese pronunciation phonemes is much larger than English and the pronunciation brain mechanisms of both also make a big difference, the adaptability of DIVA model for Chinese background has to be studied specially, in order that the model can “read out” the thinking processes in Chinese brain. Based on DIVA, the Chinese pronunciation of diphthongs was explored and related issues on Chinese brain regions involved speech production and acquisition were discussed. The new modified model can distinguish Chinese vowels from English vowels clearly by adjusting formant and the parameters of the corresponding pronunciation organs in DIVA's simulative vocal tract. This research lays a solid foundation for further comprehensive Chinese speech production and acquisition on DIVA model.

Key words: DIVA model, speech sound, Chinese compound vowel, LPMCC
