Speech recognition is a challenging yet important speech technology. First, an introduction proposes components of typical automatic speaker recognition system. Two modes like enrollment mode and recognition is discussed. Then the authors discuss about feature extraction. It is used to reduce the dimensionality of the input vector while maintaining the discriminating power of signal. After this Gaussian mixture modeling is discussed, which the speaker is modeling technique used in most systems. Vector quantization process is also discussed and then paper highlights on super-vectors.
