Study of Neural Mechanism of Mandarin Vbwel Perception and Diphthong Produetion with Neural Network Model

With the increase in the aging population, along with a need for early intervention, the number of people with various degrees of speech and hearing disorders has also increased. Communicative disorders, including the inability o express needs and feelings, greatly affect the quality ofdaily life. An understanding of the mechanisms of norrnal and disordered speech will improve the diagnosis and treatment of speech probtems, Much investigation has been done on both normal and disordered speech production, based on analysis of speech sound recordings, articulatory movement tracings, and neuroimaging (e,g. Peterson and Barney 1952, Guenther and ([ljaja 1996, Heiss et al. 2003, Bartle-Meyer et al, 2009, Kim and Max 2014). Speech production is a complex process where the shapes of articulatory organs are changed continuously to create acoustic wavefbrms, perceived by listeners as speech sounds. Numerous physiological models of human
