    摘要： A speech enhancement method, including the steps of: (a) segmenting an input speech signal into a plurality of frames and transforming each frame signal into a signal of the frequency domain; (b) computing the signal-to-noise ratio of a current frame, and computing signal-to-noise ratio of a frame immediately preceding the current frame; (c) computing the predicted signal-to-noise ratio of the current frame which is predicted based on the preceding frame and computing the speech absence probability using the signal-to-noise ratio and predicted signal-to-noise ratio of the current frame; (d) correcting the two signal-to-noise ratios obtained in the step (b) based on the speech absence probability computed in the step (c); (e) computing the gain of the current frame with the two corrected signal-to-noise ratios obtained in the step (d), and multiplying the speech spectrum of the current frame by the computed gain; (f) estimating the noise and speech power for the next frame to calculate the predicted signal-to-noise ratio for the next frame, and providing the predicted signal-to-noise ratio for the next frame as the predicted signal-to-noise ratio of the current frame for the step (c); and (g) transforming the result spectrum of the step (e) into a signal of the time domain. The noise spectrum is estimated in speech presence intervals based on the speech absence probability, as well as in speech absence intervals, and the predicted SNR and gain are updated on a per-channel basis of each frame according to the noise spectrum estimate, which in turn improves the speech spectrum in various noise environments.

    摘要： A speech signal encoding/decoding method is provided. The method of encoding LPC coefficients includes dividing the nth-order line spectral frequencies into lower, middle and upper code vectors, quantizing the middle code vectors using a middle code book to generate a first index, selecting one of a plurality of lower code books according to the lowermost line spectral frequency of the middle code vector and the line spectral frequencies of the lower code vectors, and quantizing the lower code vectors using the selected lower code book to generate a second index, selecting one of a plurality of upper code books according to the uppermost line spectral frequency of the middle code vector and the line spectral frequencies of the upper code vectors, quantizing the upper code vectors using the selected upper code book to generate a third index, and transmitting the first, second and third indexes. In the above quantization, the line spectral frequencies are quantized using a linked split vector quantization (LSVQ), and the search of the code book is efficiently performed, so that the spectral distortion and outlier percentages are lower at 23 bits/frame than those of the split vector quantization (SVQ) at 24 bits/frame.
