Current Collaborations



On speech technologies research, we are not alone. We have established three associate labs with the most famous institutes that deal with speech technologies in China.



University of Science and Technology of China (USTC)


The University of Science and Technology of China is one of the top universities in China for its academic research in science and technology. USTC iFLYTEK Speech Lab was co-founded by USTC and iFLYTEK and is dedicated to the research and development of computer intelligent interfaces and multi-media information technologies. The lab has carried out more than 10 national projects. Their research areas include:

Chinese/multi-language continuous speech synthesis
Chinese text analysis and language model
Multi-language mixed text analysis and processing methods
Key word speech recognition
Speech encoding/conversion
Embedded speech synthesis/recognition
Human-machine dialog systems
