• Early Diagnosis of Autism through Analysis of Pre-Speech Vocalizations

  Keshi Dai · 2007 · SIGACCESS Accessibility and Computing

  This paper proposes an approach for early diagnosis of autism spectrum disorder (ASD) by computationally analyzing the pre-speech vocalizations of infants aged 6 to 18 months. The author notes that while autism can be reliably diagnosed by age 3, and potentially as early as 12…
