Isolated Word Speech Recognition Techniques and Algorithms

Speech technology and systems in human computer interaction have witnessed a stable and remarkable advancement over the last two decades. Speech recognition system recognizes the speech samples. There are many speech recognition systems implemented based on well known algorithms. Generally speech recognition systems have two parts the first part is feature extraction and second part is classification. There are so many algorithms for feature extraction and classification. The Mel-Frequency Cepstral Coefficients (MFCC) algorithm as the main algorithm used for the features extraction of all the set of distinct words. implemented the Vector Quantization (VQ) algorithm for the features classification/matching and pattern recognition.
