VAD, feature extraction and modeling techniques for speaker recognition - a review by B.G. Nagaraja Abstract: This article reviews an automatic speaker recognition technology, with an emphasis on state-of-the-art voice activity detection (VAD), feature extraction and speaker modeling techniques that have emerged during the last few years. Researchers in the field of speaker recognition have made a few attempts to recognize the speaker in the language mismatch environment and limited data condition. To address robustness issues, we also elaborate language mismatch and limited data speaker recognition. Further, this paperrnidentified some issues with the existing speaker recognition systems and also investigated areas of possible improvements in speaker recognition field. We conclude the paper with a discussion on the possible future directions. Keywords: VAD; speaker identification; speaker verification; language mismatch; limitedrndata; multilingual; features; modeling techniques.
