| Summary: | 碩士 === 國立中央大學 === 電機工程研究所 === 97 === In linguistics, Chinese tone is related to the Chinese word and sentence recognition rates. Neuropsychologically, issues of neural correlates on Chinese tone are still inconclusive. The purpose of this study is to investigate neural correlates on Chinese tone using a Neural Network Model – DIVA model ( Directions Into Velocities Articulator) . This study modified the original DIVA model to include additional tone production to simulate Chinese tone production and the resulted brain activation. Simulated results (different vowels with the same tone ( /a/ - /u/ ) and training process of different vowels with the same tone (/a/ - /i/)) verified new functions of the modified DIVA model. Further simulation on the same vowel with four different Chinese tones production(ㄚ、ㄚˊ、ㄚˇ、ㄚˋ)were implemented and compared to the results of published clinical studies. Similar brain activation areas were found on the larynx area in the motor cortex, pre-motor, and somatosensory cortices set by the DIVA model. These simulated results show that the improved DIVA model could be used to study the neural correlates on Chinese tone production.
