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 …

Recent Advancements and Comprehensive Review on Hyphenated Techniques
Abstract: Hyphenated techniques represent a powerful class of analytical methods that combine two or more established techniques – typically a separation method with a spectroscopic detection technique – to achieve enhanced analytical performance. First introduced by Hirschfeld in 1980, the term “hyphenation” refers to the online coupling of such methods, enabling more precise, sensitive, and comprehensive analysis of complex samples. These techniques exploit the strengths of individual methods while overcoming their …
