| 摘 要： | 该文针对多人说话改变点检测问题，提出一种新的改进型BIC话者改变检测算法.该算法基于BIC准则确定初选改变点，再对其端点的变化趋势做进一步分析，得出说话人改变的分割点.该算法准确率达到90.2%，召回率达到95.8%.与传统BIC检测算法相比，计算更简便，准确率与召回率分别提高了62.5%和16%.

| Abstract: | To detect the voice change of speakers, an improved BIC algorithm is proposed in this paper. The algorithm chooses the segmentation point, and then analyzes the trend to locate the voice changing point of speakers. Precision of the algorithm is 90.2 % and the recall rate is 95.8 %. Compared with the traditional BIC algorithm, this new algorithm has lower computational complexity, with precision and recall rate improved by 62.5% and 16% respectively. |

| Keywords: | BIC detection segmentation changing point precision recall rate |
