I developed and realized a very low MIPS and memory footprint ASR/command recognition system. More specifically, I completed following works - AM model training, quantizing- Decoding graph construction, which means user can define their own command set (or grammar).- Decoder implementation and porting. I've designed low MIPS/memory fixed-point decoder.

I joined the Lenovo AI Lab and developed trigger system combined with speaker verification using deep learning framework. I also realized acoustic echo cancellation and beamforming techniques to make trigger and cloud-based ASR more robust.

I developed and realized a very low MIPS and memory footprint voice wake up system from scratch. It has successfully applied on several MTK’s chips, including Helio X20 and X25 series. Moreover, it is adopted by Meizu high-end pro6 smartphone. In addition to wake up feature, I have involved in several ML-related projects, such as gesture recognition with.

I developed a low MIPS fixed-point feature extraction: LPC feature with Levinson–Durbin recursion. I also developed a fixed-point single channel noise reduction method.
