The speech model, noise sources, perceptual aspects of speech, and performance evaluation are reviewed. The intelligibility enhancement system based on spectral subtraction technique is investigated. Spectral density estimation device based on the algorithm of smoothed periodograms is analysed. Determination of the silence intervals, efficiency of the silence intervals determination, and signal to noise ratio evaluation are discussed. Speech intelligibility enhancement device is described.
