Autism Spectrum Disorder

1.4K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

科学领域:

  • 神经科学是一个神经科学.
  • 语音科学 语言科学
  • 发展心理学 发展心理学

背景情况:

  • 早期发现自闭症谱系障碍 (ASD) 对干预至关重要,但目前使用脚本任务的基于语音的方法是有限的.
  • 由于任务限制和概括性问题,自动检测ASD儿童的语言异常面临着挑战.

研究的目的:

  • 开发和评估一个基于非脚本语音的语音框架,用于量化非典型的声学-音模式,用于自动识别ASD.
  • 为了使大规模的非临床查ASD使用自然的相互作用.

主要方法:

  • 在自然主义互动期间,从ASD儿童和典型发育 (TD) 儿童那里收集自发言语.
  • 从自由流动的对话中提取了多维的声学特征.
  • 利用线性差异分析来建模和分类与ASD相关的前性模式.

主要成果:

  • 在ASD儿童中确定了显著的非典型的前奏模式,包括语音连续性减少和音调变化增加.
  • 取得了强大的分类性能 (准确度 = 0.85 ± 0.07,F1 = 0.86 ± 0.07).
  • 发现非典型模式在开放式对话中更明显,与语言能力相关.

结论:

  • 无脚本语音分析对于捕捉ASD中非典型的前性模式至关重要.
  • 开发的框架显示出在临床环境之外进行大规模ASD查的前景.
  • 声学-prosodic模式可以作为评估ASD严重性的客观标记.
