In this study, the calculations and results of acoustic voice analysis as calculated by two different analysis systems (Doctor Speech (DRS), Tiger Electronics, Neu-Anspach, Germany, and Computerized Speech Lab (CSL), Kay Elemetrics Corporation, Lincoln Park, NJ) are compared. A group of 120 normal voices was selected for analysis of the objective parameters: fundamental frequency (F(0)), variation of F(0) (F(0)SD), jitter, shimmer, and harmonics-to-noise ratio (HNR). The subject group was a random selection of normal voices of adults. The aim of this comparison was to find determined differences and similarities in data measurements between both systems to make data transfer possible. A significant correlation was found for F(0), HNR, and shimmer relative. The correlation for jitter (relative and absolute) and F(0)SD was weak. DRS and CSL are not comparable in absolute figures, but their judgment against normative data is identical. Further research is necessary to explore the affect on pathological voices or child voices.
在本研究中，对由两种不同分析系统（德国新安斯巴赫的虎牌电子公司的Doctor Speech（DRS）和新泽西州林肯公园的凯伊电子测量公司的计算机语音实验室（CSL））计算得出的声学语音分析的计算结果进行了比较。选取了120个正常嗓音样本组成一组，用于分析客观参数：基频（F(0)）、F(0)的变化（F(0)SD）、抖动、闪烁和信噪比（HNR）。研究对象组是从成年人的正常嗓音中随机选取的。此次比较的目的是找出两个系统在数据测量方面确定的差异和相似之处，以使数据传输成为可能。结果发现，F(0)、HNR和闪烁相对值之间存在显著相关性。抖动（相对和绝对）与F(0)SD的相关性较弱。DRS和CSL在绝对数值上不可比，但它们相对于标准数据的判断是相同的。有必要进行进一步研究，以探索其对病理性嗓音或儿童嗓音的影响。
