DIVA(Direction Into Velocities of Articulators)模型作为一种数学模型,能够较为准确地描述人脑中涉及语音生成和语音理解脑区所发挥的作用,并对其过程进行模拟.但是DIVA模型所采用的语音感兴趣区域是基于英语语音研究而制定的.在汉语语音研究过程中,原有的感兴趣区域在反映汉语任务的脑区激活状态方面存在诸多不足.文章对汉语语音加工过程进行功能磁共振成像实验研究,并基于DIVA模型对实验结果进行分析后发现:与英语语音研究结果相比,右侧颞叶后部及相邻的缘上回,双侧枕叶腹侧区域出现了不同的激活状态.该实验结果为以后对DIVA模型进行汉语语音相关修改提供了良好的基础.
As a mathematical model, DIVA (DIVA) model can describe the function of human brain involved in speech generation and speech understanding more accurately and simulate its process.But the speech of DIVA model The region of interest is based on the study of English phonetics.In the process of Chinese phonetics research, there are many deficiencies in the original region of interest in reflecting the activation of brain regions in Chinese tasks.First, the functional speech of Chinese phonetics processing Based on the DIVA model, the experimental results were analyzed and it was found that compared with the results of the English phonetics, different states of activation were found in the posterior part of the right temporal lobe and the ventral region of the bilateral occipital lobe, The experimental results provide a good foundation for the subsequent modification of Chinese speech in DIVA model.
