Besides,they also visited the aptitude lab of Professor Chen Xiaoping in Computer department,the Xunfei sound lab of professor Wang Hua in electron and information department,and professor Wei Guo and Wang Weidong's wireless net lab.

此外，沈院长一行还分别参观了我校计算机系陈小平教授的多智能体系统实验室、电子工程与信息科学系王仁华教授的讯飞语音实验室，以及卫国、王卫东教授的无线网络通信实验室。

Emphasis is laid on the research progress in the field of new generation speech synthesis technology contributed by USTC iFlytek speech laboratory, which includes integration articulatory and acoustic features for improving the flexibility of acoustic parameter generation; a minimum generation error criterion proposed to replace maximum likelihood for improving synthesized speech quality; use of unit selection and waveform concatenation to replace parametric synthesizer, thus effectively avoiding the limitation of speech quality in HMM based parametric synthesis.

重点介绍中国科学技术大学讯飞语音实验室在发展新一代语音合成技术中的贡献，包括：融合发音器官参数与声学参数，提高声学参数生成的灵活性；以最小生成误差准则取代最大似然准则，提高合成语音的音质；使用单元挑选与波形拼接方法取代参数合成器重构，从根本上改善HMM参数语音合成器在合成语音音质上的不足。
