基音

To realize the analysis of short time of speech signal by Matlab, including the judgement of surd and sonant, the estimate of the pitch and experiment report.

用matlab实现对语音信号的短时分析，包括清音和浊音的判决，基音周期的估计，实验报告。

Firstly,surd or sonant judgment with each voice frame is done,then the multi-scale wavelet analysis is done only on the sonant frames to get pitches.In order to get accurate pitches,the intervals of local modulus maxima of dyadic wavelet coefficients are corrected according to amplitude information and appearance probability information.

针对这一问题，提出一种基于小波变换的基音周期提取改进算法，将TEO算子与二进小波变换结合起来，首先进行清浊判定，然后只对浊音帧采取多尺度小波分析提取周期，提出用幅度信息和出现概率信息校正二进小波模极大值间距，从而得到准确的周期。

The normalized cross-correlation coefficients, short time normalized energy and adaptive threshold to classify surd/sonant and to select pitch candidates with the high-resolution and efficient implementation are used in NCCFPDA.

In the former stage, Based on the concept that both glottal excitation and vocal tract parameters are time varying in amplitude and frequency, we detect pitch with frequency domain transform

在波形合成阶段，以基音频率轨迹为依据，将混叠语音信号分割为独立的短时周期信号，利用数字多谐振荡器的选频特性，获取相应的各次谐波的频率、幅度以及相位信息，利用这些参数在频域叠加来合成

Some information such as pitch and harmonic of each speech stream, interaural time difference and interaural intensity difference and etc could be obtained from overlapping speech by the analyzing and modeling of overlapping speech and noisy speech, based on which the interested speech can be reconstructed and overlapping speech can be separated.

通过对混叠语音和含噪语音进行分析建模，对混叠语音分别提取其各自语音流的基音及谐波、双耳时间差ITD和强度差IID等信息，并以此重构目标语音分量，达到分离混叠语音的目的。

The experimental analysis show that the new method has better than that of conventional approach, it may provides a higher accuracy and resolution in speech detection, and improve the reliability of voiced/unvoiced decisions.

通过实验分析表明，该方法与传统方法相比，提高了基音周期提取的准确性和分辨率，增强了清浊音判决的可靠性。

Two-channel frequency-domain analysis is used to find the fundamental frequency of unvoiced speech signals, and then to control the stimulation rate of current pulses.

基于传统的汉语语音声调提取方法，采用双通道的频域分析法进行基音分析，提取汉语语音声调的变化轨迹，控制刺激模式的产生。
