Abstract
Children with autism spectrum disorder and children with cochlear implants can experience phonological deficits. This study examines the acoustic profiles of the speech of ten Bangla-speaking children with either cochlear implant or autism spectrum disorder. A Bengali phonological picture test set as well as a narrative picture test were used as stimuli to elicit responses. Both groups exhibited significant articulation and/or phonological deficits in syllable, word, and sentence utterances. More specifically, to pronounce the different words, phrases, and sentences they frequently encountered phonological problems like stress, pitch, tone, intonation, and loudness. In the current study, PRAAT software was used by the researchers to analyze acoustic data. The analysis resulted in ten individual profiles of the speech of children with speech sound disorder. The children with a cochlear implant exhibited more phonological deficits than autistic children.
