与发育正常的说话者相比，高功能自闭症（HFA）说话者的非典型韵律是否有一致的标记？我们检查了：（1）对话中的音高范围、平均音高和语速的声学测量，（2）这些特征和整体韵律的对话的感知评级，以及（3）来自结构化任务的语音的声学测量。在谈话和结构化交流中，发现HFA扬声器的音高范围增加。在全球评分中，听众将具有HFA的演讲者评为具有非典型韵律。虽然HFA组表现出增加的声学音高范围，听众没有率扬声器与HFA作为具有增加的音高变化。我们认为，与HFA扬声器所使用的音高变化的质量是非常规的，因此不登记为这样的听众。
Are there consistent markers of atypical prosody in speakers with high functioning autism (HFA) compared to typically-developing speakers? We examined: (1) acoustic measurements of pitch range, mean pitch and speech rate in conversation, (2) perceptual ratings of conversation for these features and overall prosody, and (3) acoustic measurements of speech from a structured task. Increased pitch range was found in speakers with HFA during both conversation and structured communication. In global ratings listeners rated speakers with HFA as having atypical prosody. Although the HFA group demonstrated increased acoustic pitch range, listeners did not rate speakers with HFA as having increased pitch variation. We suggest that the quality of pitch variation used by speakers with HFA was non-conventional and thus not registered as such by listeners.
