我们设计并实现了一种用于实时检测语音基频（pitch）、提取音乐旋律（melody）的软件。

语音或者音乐的基频是一种很重要的特征，可以用在很多研究与应用中。比如：用于普通话语音声调的识别和确认；语音流利度的分析；音乐旋律的提取用于哼唱检索等。读者可以参考我们之前的博文：http://blog.sciencenet.cn/home.php?mod=space&uid=907554&do=blog&id=723808-We design and implement software for real-time detection of voice fundamental frequency (pitch), extract music melody (melody) of.

The fundamental frequency of the voice or music is a very important feature, can be used in many studies and applications. For example: for Mandarin speech recognition and confirmation tone　analysis of speech fluency　extract melodies for humming retrieval.
