Real-valued Gabor Transforms for Speech Analysis
Zhenquan Zhuang · Modern Computer · 2000
In this paper, we present fast real-valued discrete Gabor transforms (RDGTs) for speech signal representation and develop a new method to compute the speech spectrogram and the form of the speech spectrogram from the RDGT coefficients. The reconstruction of speech signal is also discussed and some experimental examples are given at the end of this paper.
