Abstract

As a mathematical tool, DIVA(Directions Into Velocities of Articulators) model can accurately describe and simulate the functions of human brain areas responsible for speech production and understanding. However, the speech regions of interest used in DIVA model was developed based on English. For Chinese speech studies, the original regions of interest fail to reflect the brain activation state for Chinese tasks. In this paper, a functional magnetic renonance imaging study is carried out for Chinese speech processing. Based on DIVA model, it is found from the results that, compared to results concluded for English, there are different activation state in the right posterior temporal lobe and adjacent supramarginal gyrus and the bilateral ventral occipital areas. The experimental results provide a good foundation to the future Chinese speech related modification of DIVA model.
