【Abstract】 In this paper we present fast real－valued discrete Gabor transforms RDGT for speech signal representation and develop a new method to compute the speech complex spectrogram and the speech spectrogram generation from the RDGT coefficients． The fast reconstruction of speech signal is also discussed and some experimental examples are given．更多还原
