Executive Summary (About Self)

He has strong research background based on speech recognition, noise robust acoustic feature extraction, audio-visual speech recognition. Has rich experience of working in a team actively and collaboratively, and also strong motivation to advancement of speech technology research.
The continuous research on speech technology has helped him acquire unique skills and in-depth understanding on HMMs, MFCC, and Wavelets etc. He has extracted both audio and visual features. For example, a paper on Hindi phoneme-viseme recognition from continuous speech was published at Int. J. Signal and Imaging Systems Engineering- Inderscience in 2013. Another paper on hybrid features for speaker independent Hindi digits recognition using HTK toolkit was published in 2013. His recent work of audio visual based feature fusion approach for speech recognition was published in 2015. To summarize, he has published 11 journal papers and 5 International conferences including reputed ones like ICDIP and FRSM on speech processing area.
The long years of experience on using HTK, Matlab, Praat’s helped him to develop his skill on speech recognition area, thus he can give a series of in-depth talks on recent trends of speech recognition. Within HTK framework, he can use other features extracted from MATLAB. His audio visual based features enhanced the performance of speech recognizer by a significant margin compared to the traditional features.
Besides investigation on HMM theory and speech recognition fundamentals and its implementation in HTK, he has frequently updated his knowledge on recent trends on speech technology.
He has directed interns or freshman on several speech recognition projects for Hindi speech recognition, and he is a consultant of speech recognition in his team. Communication skills are well demonstrated through our collaboration.
