在这项初步研究中，我们试图确定通过电话传输收集语音和声音声学数据的可靠性和有效性，以备将来在大型临床试验中使用。同时记录每个参与者的发言和声音，在参与点，本地录音（LR），并通过电话线使用专用的在线计算机交互式语音记录系统，远程录音（RR）。所有语音记录均从位于康涅狄格州格罗顿的实验室电话至位于威斯康星州麦迪逊的RR系统进行。在LR和RR记录之间逐个测量比较所有数据点。结果表明，这两个措施的频率偏移和语音电机定时可靠地捕获通过电话。结果进行了讨论，在特定的声学措施，可能是有用的，并通过电话传输准确测量，检查疾病的严重程度和药物干预，用于大规模的临床试验。
In this pilot study we sought to determine the reliability and validity of collecting speech and voice acoustical data via telephone transmission for possible future use in large clinical trials. Simultaneous recordings of each participant's speech and voice were made at the point of participation, the local recording (LR), and over a telephone line using a dedicated in-line computerized interactive voice recording system, the remote recording (RR). All voice recordings were made from our laboratory telephone located in Groton, Connecticut to the RR system located in Madison, Wisconsin. All data points were compared on a measure-by-measure basis between the LR and RR recordings. The results suggest that both measures of frequency excursion and of speech motor timing are reliably captured over the telephone. Results are discussed in terms of specific acoustic measures that may be useful and accurately measured via telephone transmission, for examining disease severity and pharmacological intervention for use in a large-scale clinical trial.
