Speakers in informal conversations tend to alternate regularly between lower and higher amounts of talking; the periods of these low/high activity cycles are on the order of 3, 6, and 15 minutes. Statistically significant periodicities occurred in 55% of the conversations studied. The periodograms that describe the partition of variance among periodic components show consistent individual differences in the cyclic patterning of vocal activity. Discriminant analysis used the amount of variance accounted for by each of the 12 lowest-frequency periodic components as discriminating variables to see whether speakers could be identified on the basis of the cyclic patterns in vocal activity. Speakers were discriminated and classified at levels well above chance. This suggests that there are consistent individual differences among speakers in the length of cycles in amount of talk.
在非正式对话中，说话者往往会在较少和较多的说话量之间有规律地交替；这些低/高活动周期的时长约为3分钟、6分钟和15分钟。在所研究的55%的对话中出现了具有统计学意义的周期性。描述周期性成分之间方差划分的周期图显示，在语音活动的循环模式上存在一致的个体差异。判别分析将12个最低频率周期性成分各自所解释的方差量用作判别变量，以查看是否可以根据语音活动的循环模式识别说话者。说话者能够以远高于随机水平的准确率被区分和分类。这表明，说话者在说话量的周期长度方面存在一致的个体差异。
