非典型韵律，经常在自闭症谱系障碍儿童中报道，是用一系列定性术语来描述的，这些术语反映了谱系中个体的怪癖和可变性。我们研究了自发语音的各种单词和语音水平特征，这些特征可以量化反映韵律的线索。此外，我们还介绍了在这种二元互动中共同建模心理学家发声行为的重要性。我们证明了两个参与者的声学韵律特征与儿童的自闭症严重程度有关。为了增加感知的非典型化，我们发现儿童的韵律特征表明“单调”的言语、可变的音量、非典型化的语音质量和较慢的语速。此外，我们发现心理学家的特征会影响他们对儿童非典型行为的感知——例如，心理学家的俯角斜率和抖动越来越多变，他们的语速通常会下降。
Atypical prosody, often reported in children with Autism Spectrum Disorders, is described by a range of qualitative terms that reflect the eccentricities and variability among persons in the spectrum. We investigate various wordand phonetic-level features from spontaneous speech that may quantify the cues reflecting prosody. Furthermore, we introduce the importance of jointly modeling the psychologist’s vocal behavior in this dyadic interaction. We demonstrate that acoustic-prosodic features of both participants correlate with the children’s rated autism severity. For increasing perceived atypicality, we find children’s prosodic features that suggest ‘monotonic’ speech, variable volume, atypical voice quality, and slower rate of speech. Additionally, we find the psychologist’s features inform their perception of a child’s atypical behavior– e.g., the psychologist’s pitch slope and jitter are increasingly variable and their speech rate generally decreases.
