Abstract

Recognition by adults of the psychoneurological state of children with autism spectrum disorders (ASD), n = 35, and typically developing (TD) children, n = 47, aged 5–14 years, was studied. A perceptual analysis was carried out, in which adult native Russian speakers (auditors) took part, n = 206. For perceptual analysis, test sequences (audio tests) were created containing words and phrases of children with ASD and TD children, selected from spontaneous speech recordings. The auditors were faced with the problem of determining the psychoneurological state of a child based on auditory perception: typical–atypical development. A spectrographic analysis of the speech material of children with ASD and TD children was carried out. The phrases of children with ASD are characterized by a lower speech rate compared to the phrases of TD children, as well as fewer words, longer duration of stressed and unstressed vowels in words, higher values of the frequency of the fundamental tone in the phrase, word, and stressed and unstressed vowels.

根据语音信号识别自闭症谱系障碍儿童的精神神经状态：声音和感知特征

研究了成人对 5-14 岁自闭症谱系障碍（ASD）儿童（35 人）和发育正常（TD）儿童（47 人）精神神经状态的识别。进行了感知分析，以俄语为母语的成人（听者）参加了分析，人数为 206 人。为了进行知觉分析，我们制作了测试序列（音频测试），其中包含从自发言语录音中选取的 ASD 儿童和 TD 儿童的单词和短语。听力测试者面临的问题是根据听觉感知判断儿童的心理神经状态：典型-非典型发展。我们对患有自闭症的儿童和患有精神发育障碍的儿童的言语材料进行了光谱分析。与 TD 儿童的短语相比，ASD 儿童短语的特点是语速较低，单词数量较少，单词中的重读和非重读元音持续时间较长，短语、单词、重读和非重读元音中的基音频率值较高。
