We propose methods to track natural variations in the characteristics of the vocal-tract system from speech signals. We are especially interested in the cases where these characteristics vary over time, as happens in dynamic sounds such as co

基于Hilbert-Huang变换的语音信号共振峰频率估计，一种对语音信号的分析方法-Based on the Hilbert Huang transform of speech signal formant frequency estimation, a method on the analysis of the speech signal

his MATLAB exercises illustrates an algorithm for estimating the locations of the formants of voiced speech intervals based on the locations of the speech polynomial roots as obtained a frame-based analysis of a speech signal using the method of Line
