Investigating AI Applications in Communication Tools for Individuals with Speech Impairments: An In-depth Analysis

Speech is a fundamental means of expressing thoughts and emotions, but individuals with speech disorders face challenges that impact their self-esteem and overall quality of life. These disorders are categorized into speech impairments, which involve issues with speech sounds, fluency, and voice, and speech impediments, which result from physical difficulties in speech production, such as stuttering and articulation errors. A variety of causes, both medical and external, contribute to these disorders, affecting individuals of all ages. Traditionally, therapy for speech disorders involved in-person sessions, but technology has introduced Augmentative and Alternative Communication (AAC) solutions, including AI-powered mobile apps, offering accessible communication to a global audience. This research paper presents an overview of AAC tools, a systematic review of AI in AAC, an exploration of existing AAC applications, and a literature review on technology's impact. The paper highlights the transformative impact of AAC on individuals with speech disabilities and emphasizes the potential of AI-based solutions to enhance communication. It calls for the integration of speech recognition, reconstruction, and contextualization in AAC applications, promising improved support for those with speech disorders.
