This study investigated the effect of speech dialect on listeners' speech naturalness ratings by systematically replicating Martin, Haroldson, and Triden's (1984) study using three groups of speaker samples. Two groups consisted of speakers with General American dialect--one with persons who stutter and the other with persons who do not stutter. The third group also consisted of speakers who do not stutter but who spoke non-General American dialect. The results showed that speech naturalness ratings distinguished among the three speaker groups. The variables that appeared to influence speech naturalness ratings were type of dialect, speech fluency, and speaking rate, though they differed across speaker groups. The findings also suggested that strength of speech dialect may be a scaleable dimension that judges can rate with acceptable levels of reliability. Dialect may also be an important factor that needs to be incorporated or controlled within systems designed to train speech naturalness ratings. It may also be an important factor in determining the extent to which stuttering treatment produces natural sounding speech.
本研究通过使用三组说话者样本系统地重复马丁、哈罗德森和特里登（1984年）的研究，调查了语音方言对听众语音自然度评分的影响。两组由具有通用美国方言的说话者组成——一组是口吃者，另一组是非口吃者。第三组也由非口吃但说非通用美国方言的说话者组成。结果表明，语音自然度评分在三组说话者之间存在差异。似乎影响语音自然度评分的变量是方言类型、言语流畅性和说话速度，尽管它们在不同的说话者组中有所不同。研究结果还表明，语音方言的强度可能是一个可量化的维度，评判者可以以可接受的可靠性水平进行评分。方言也可能是一个重要因素，需要在旨在训练语音自然度评分的系统中加以纳入或控制。它也可能是决定口吃治疗在多大程度上产生自然语音的一个重要因素。
