The Contextual Effect of Vowels on Correct Production of Retroflex in Kannada Speaking Children with Speech Sound Disorder: A Case Study
Abstract: Contextual based interaction of speech sounds, coarticulation, is the main component of intelligible continuous speech. This interaction between speech sounds within and across the words is affected in children with speech sound disorders (SSD). Literature reports on certain contexts facilitating the production of different speech sounds. Thus, these contextual considerations are vital for the selection of target stimuli during articulation therapy for faster learning. As phonotactics and coarticulation are language …
