摘要
本文首先简要介绍了基音频率的检测过程,然后对不同年龄层次、不同性别说话人和不同辅音作用下的语音数据,按照不同的帧长进行基音检测。实验证明:在不同情况下,选择不同帧长对基音检测的精确度和鲁棒性都是有一定影响的。
In the paper, the process of the pitch frequency detection is firstly introduced, then the speech data of speakem of different ages , sexes as well as the speech data with variable consonant actions are estimated with different length of frame. Experimental results show that different length of frame will influence the precision and the robustness in pitch detection.
