摘要：
强混响环境下的话者数量是语音处理应用中的关键信息.以不同话者语音之间的频域幅度平方相干（Magnitude Squared Coherence，MSC）为特征进行话者计数，首先提取语音中的短时频域MSC特征，再采用K?medoids算法对其进行聚类得到话者个数.该方法无需麦克风间距和话者到麦克风之间相对距离的先验信息.不同混响条件、不同信噪比和不同麦克风间距的实验结果表明，频域MSC特征与话者是相干的，与基于广义互相关相位变换（Generalized Cross?Correlation Phase Transform，GCC?PHAT）的到达时间差方法（Time Difference of Arrival，TDOA）相比，本方法的话者计数准确率更高，对麦克风间距的敏感度更低，鲁棒性更优.
