Previous research has demonstrated differences in the acoustic features of crying signals between deaf and typical hearing (TH) infants. This study aims at comparing the acoustic parameters of cries of infants with different degrees of deafness versus TH infants. About 110 infants aged 6-12 months (61 TH infants, 34 infants with bilateral deafness…

There is preliminary evidence that infant siblings of children with Autism Spectrum Disorder (ASD) have an atypical pattern of cry, characterized by higher fundamental frequency and increased dysphonation. This prospective study collected multiple cry samples of 12-month old siblings of children with ASD (n = 22, "high-risk" group) and…

Episodes of crying with higher fundamental frequency (f0) are perceived as more aversive and distressful than lower frequency cries. Besides, previous studies have speculated that in children with Autism Spectrum Disorder (ASD) higher f0 may account for evoking mental states of uneasiness in the caregiver. Moreover no evidence on developmental…

Conducted spectrum analysis of standard and vociferous cries from infants with Wessel's colic, non-Wessel's colic, and comparison infants. Vociferous cries had longer duration, higher fundamental frequency, and greater percentage of dysphonation than standard cries. After feedings, problematic criers had greater percentage of dysphonation in…

Examined differences in acoustic characteristics of cries, both early and late, within a prolonged crying bout. Results indicated that late cries appeared to result from a smaller number of factors than did early cries. Results support notions that crying bouts settle into a regular cry with acoustic features matching a theoretical model of cry…
