In this paper, we present a novel approach to vector quantization in which a feature vector is represented by a binary vector. It is called binary quantization (BQ). The performance criterion of vector quantization, distortion (distance) measure, was employed for investigating the effectiveness of BQ. At 12 b/analysis frame, the average distortion caused by(More)
A new method of spectral subtraction is proposed in this paper. Through selective application of common spectral magnitude subtraction, distortion in the processed speech can be reduced significantly without compromising on the amount of residual noise. The decision for the selection can be obtained from the noisy speech itself. A scheme for reducing the(More)
