用于语音分析的实值离散GABOR变换

Real-valued Gabor Transforms for Speech Analysis

本文提出了语音信号的快速实值离散Ｇａｂｏｒ变换（ＲＤＧＴ）方法，讨论了由ＲＤＧＴ系数计算语音复谱图值、语谱图生成和语音信号的快速重建问题，并在文末给出了实例。

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.
