一种整数基音检测新方法STA的实用改进

Improvement on STA——a new method in integer pitch determination

对新的基音检测算法STA作简要介绍,对于在基音检测的实际应用中,遇到的由于受到噪声、共振峰影响造成基音周期检测点的偏移问题,提出STA的改进方案ISTA,并对前后2种方案的实际效果进行了比较,ISTA在基音检测时可以得到比STA更理想的效果.

A new method named STA is explained in pitch determination. A series of problems are found in the application of STA, so some improvements on it are made. A better effect is gained in the latter method named ISTA.
