7th International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2011)
Autism Spectrum Disorders (ASD) show an increasing prevalence in children, and are often undiagnosed up to the third year of life. Analysis of cry patterns appears a promising approach for allowing an early ASD detection and diagnosis. In this work we compare the main acoustic parameters collected by recording infant crying in control subjects with the parameters obtained in high risk subjects, namely infant siblings of children with ASDs. Results confirm previous finding obtained using home video recordings, and indicate a weaker coupling between fundamental frequency and first resonance frequencies in high risk subjects.
Index Terms. Autism Spectrum Disorders, cry analysis, fundamental frequency, resonance frequencies.
