A Case Study on Vocal Loudness With a Young Adult With Autism Spectrum Disorder and Developmental Delay.

Purpose: This clinical focus article describes an exploratory case study addressing reduction of vocal loudness in a young adult with a history of autism spectrum disorder and developmental delay. The need for a short-term pullout individual intervention arose from his participation in the Advancing Language and Literacy group, a program that provides support for enhancement of speech, language, and literacy skills for young adults with developmental disabilities.

Method: The participant attended individual treatment sessions weekly for 9 sessions, all of which were digitally audio-recorded.
