Our research focuses on designs and algorithms for real-time digital signal processing/speech processing-based systems.
In our lab, a huge microphone-array (HMA) system that supports real-time processing and data acquisition for 512 microphones has been in operation for more than seven years. It is still in use for algorithm research and data acquisition. A new microphone array (HMA2) of 128 microphones has just been built. We implemented a new locationing algorithm (SRP-PHAT using SRC) in real-time on this new array. In the future, we would like to design a teleconference environment between the two arrays.
Other research areas include speech recognition, reconfigurable computing, etc.
