The DIVA (Directions Into Velocities Articulator) model provides a computational and neuroanatomical account of speech acquisition and production; however, its prediction of speech perception and production for Mandarin is limited. The aim of this study is to modify the original DIVA model to simulate both normal and speech disordered productions in Mandarin. The proposed version of the model provides additional functions of speech perception, tonal acquisition and diphthong production. Computer simulation of our modified DIVA model verifies its ability to simulate Mandarin tonal production in diphthong and speech perception across vowels.
