is a clinical multimedia software tool developed by IBM to provide real-time visual and auditory feedback for speech and language therapy. By transforming spoken words into imaginative graphics and animations, it helps individuals with speech, language, or hearing impairments "see" how to speak, making the abstract concepts of phonetics and vocal control more concrete and engaging. Core Features and Functionality
In the evolving landscape of speech-language pathology, phonetics research, and vocal coaching, the ability to "see" sound has long been a holy grail. represents the third major iteration of this groundbreaking software platform, transforming complex acoustic signals into intuitive, real-time visual feedback. Designed for professionals and advanced students, Speech Viewer III bridges the gap between auditory perception and empirical data, offering unprecedented clarity, precision, and usability.
(2019): This thesis provides an overview of the exercises available in IBM Speech Viewer III (such as pitch and loudness feedback) and uses it as a benchmark for modern visual speech therapy apps. You can view it on ResearchGate speech viewer iii
