一个语音基频提取新算法

为了准确提取语音基频,设计了一种新的基频提取算法,并对此算法的抗噪性能进行了评估,同一段语音进行加噪和未加噪两类处理,通过实验提取两类语音的基频,以未加噪基频作为准标值,对不同信噪比的语音基频与准标值的偏离情况进行了分析,从而了解算法提取基频的抗噪性。以便全面掌握此算法的性能,达到优化算法,减小估计带来的误差,提高语音基频提取的目的。

A New Algorithm for Speech Fundamental Frequency Extraction

In order to accurately extract the voice fundamental frequency,the design of a new fundamental frequency extraction algorithm,and the antinoise performance of this algorithm was evaluated with a voice,the additional noise and without noise added two types of processing,extracting two experiments class voice fundamental frequency in order to not add noise fundamental frequency as the quasi-standard values for different signal to noise ratio of voice fundamental frequency and quasi-standard deviation values w...
