摘要：A speech signal compression and/or decompression method, medium, and

apparatus in which the speech signal is transformed into the frequency domain forquantizing and dequantizing information of frequency coefficients. The speech signalcompression apparatus includes a transform unit to transform a speech signal into thefrequency domain and obtain frequency coefficients, a magnitude quantization unit totransform magnitudes of the frequency coefficients, quantize the transformedmagnitudes and obtain magnitude quantization indices, a sign quantization unit toquantize signs of the frequency coefficients and obtain sign quantization indices, and apacketizing unit to generate the magnitude and sign quantization indices as a speechpacket.
