Fifteen speech-language pathologists with extensive experience judging speakers' intelligibility and 15 control subjects with no such previous experience provided magnitude-estimation responses for two sets of nine audiotaped speech samples. These samples were three utterances composed of a group of 17 words that contained all the consonant phonemes of English. These words were arranged to form a set of either meaningful or nonsense utterances. Nine separate versions of both the meaningful and nonsense utterances were created by systematically increasing the number of phonemes produced incorrectly on each of the nine recordings. The analysis indicated no significant difference between the magnitude-estimation scaling responses of experienced and inexperienced listeners. A significant over-all difference was found for listeners' responses to meaningful versus nonsense utterances. The advantages of magnitude-estimation scaling as a measure of speakers' intelligibility are discussed.
15名在判断说话者可懂度方面经验丰富的言语病理学家和15名此前无此类经验的对照受试者，针对两组共9个录音语音样本给出了量级估计反应。这些样本是由一组包含英语所有辅音音素的17个单词组成的三个话语。这些单词被安排组成一组有意义或无意义的话语。通过系统地增加九个录音中每个录音上错误发出的音素数量，创建了有意义和无意义话语的九个单独版本。分析表明，有经验和无经验听众的量级估计标度反应之间没有显著差异。发现听众对有意义话语和无意义话语的反应存在显著的总体差异。讨论了量级估计标度作为衡量说话者可懂度指标的优势。
