A method of measuring the rate of change of fundamental frequency has been developed in an effort to find acoustic voice parameters that could be useful in psychiatric research. A minicomputer program was used to extract seven parameters from the fundamental frequency contour of tape-recorded speech samples: (1) the average rate of change of the fundamental frequency and (2) its standard deviation, (3) the absolute rate of fundamental frequency change, (4) the total reading time, (5) the percent pause time of the total reading time, (6) the mean, and (7) the standard deviation of the fundamental frequency distribution. The method is demonstrated on (a) a material consisting of synthetic speech and (b) voice recordings of depressed patients who were examined during depression and after improvement.
为了找到可用于精神病学研究的声学语音参数，已开发出一种测量基频变化率的方法。使用一个小型计算机程序从录音语音样本的基频轮廓中提取七个参数：(1) 基频的平均变化率及其 (2) 标准差，(3) 基频变化的绝对速率，(4) 总朗读时间，(5) 总朗读时间中的停顿时间百分比，(6) 基频分布的均值，以及 (7) 标准差。该方法在以下两方面得到了验证：(a) 由合成语音组成的材料，以及 (b) 抑郁症患者在抑郁期和病情改善后的语音记录。
