这项研究考察了患有自闭症谱系障碍(ASD)的成年人对情感韵律的产生和感知。以前的研究已经报道，在语法说话任务(例如，比较疑问句和陈述句)中，与典型发展(TD)控制相比，患有ASD的说话者的音调变异性更大，但尚不清楚这种模式是否延伸到情绪性言语中。本研究从15名患有自闭症的成年男性和15名对照组中获得了五种情绪(愤怒、高兴、感兴趣、悲伤和中性)下的语音录音(实验1)，并将其呈现给52名听者(22名自闭症患者)，要求他们识别表达的情绪并对每个录音中情绪的自然度进行评级(实验2)。与TD组相比，患有ASD的说话者产生的短语强度更高，持续时间更长，除中性情绪外，所有情绪的音调范围都更大，这表明他们更大的音调变异性是特定于情绪环境的。当被要求从言语中辨别情绪时，两组听者都比TD使用者更准确地从ASD使用者的言语中识别情感语境，但认为ASD情绪言语听起来不那么自然。总而言之，这些结果揭示了患有自闭症的说话者在情感言语产生方面的差异，这为报告的患有自闭症的成年人在言语表达上的奇怪感觉提供了声学基础。这项研究考察了患有自闭症谱系障碍(ASD)和典型发育障碍(TD)对照的成年人产生和感知的情感言语交流。与TD组相比，患有自闭症的人产生的情感短语更响亮、更长，音调也更多变。与TD说话者相比，ASD和TD听众在识别ASD说话者产生的言语中的情绪方面都更准确，但他们认为ASD情绪演讲听起来不那么自然。
This study examined production and perception of affective prosody by adults with autism spectrum disorder (ASD). Previous research has reported increased pitch variability in talkers with ASD compared to typically-developing (TD) controls in grammatical speaking tasks (e.g., comparing interrogative vs. declarative sentences), but it is unclear whether this pattern extends to emotional speech. In this study, speech recordings in five emotion contexts (angry, happy, interested, sad, and neutral) were obtained from 15 adult males with ASD and 15 controls (Experiment 1), and were later presented to 52 listeners (22 with ASD) who were asked to identify the emotion expressed and rate the level of naturalness of the emotion in each recording (Experiment 2). Compared to the TD group, talkers with ASD produced phrases with greater intensity, longer durations, and increased pitch range for all emotions except neutral, suggesting that their greater pitch variability was specific to emotional contexts. When asked to identify emotion from speech, both groups of listeners were more accurate at identifying the emotion context from speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural. Collectively, these results reveal differences in emotional speech production in talkers with ASD that provide an acoustic basis for reported perceptions of oddness in the speech presentation of adults with ASD. This study examined emotional speech communication produced and perceived by adults with autism spectrum disorder (ASD) and typically-developing (TD) controls. Compared to the TD group, talkers with ASD produced emotional phrases that were louder, longer, and more variable in pitch. Both ASD and TD listeners were more accurate at identifying emotion in speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural.
