In an effort to quantify communication efficiency, speaking rates and intelligibility scores were obtained from a normal speaking adult and 13 dysarthric speakers representing a wide range of severity. Speakers were audio recorded as they read words and sentences. A panel of judges transcribed all recordings and subjectively ranked a randomly selected sample from each speaker according to "communication efficiency." The following measures were obtained for each speaker: word and sentence intelligibility, speaking rate, rates of intelligible and unintelligible speech and a numerical ranking of communication efficiency. Results indicated that speaking rate and speech intelligibility are not closely correlated. By plotting measures that incorporate intelligibility and rate, one can rank speakers similarly to subjective rankings of communication efficiency, and distinguish mildly dysarthric from normal speakers. The addition of intelligibility and rate measures to supplement other assessment procedures in the evaluation of dysarthric speakers is discussed.
为了量化沟通效率，我们从一名正常成年说话者和13名代表不同严重程度的构音障碍者那里获取了说话速度和可懂度分数。当说话者朗读单词和句子时进行了音频录制。一组评委对所有录音进行了转录，并根据“沟通效率”对每个说话者随机抽取的样本进行主观排名。为每个说话者获取了以下指标：单词和句子可懂度、说话速度、可懂和不可懂言语的速度以及沟通效率的数字排名。结果表明，说话速度和言语可懂度并非密切相关。通过绘制结合了可懂度和速度的指标，可以像对沟通效率进行主观排名那样对说话者进行排名，并区分轻度构音障碍者和正常说话者。本文讨论了在评估构音障碍者时增加可懂度和速度指标以补充其他评估程序的问题。
