The Dysarthria Analyzer represents more than a decade of rigorous scientific research and international collaboration in speech analysis and neurological assessment. Built upon peer-reviewed research and validated across multiple languages and disorders, this cutting-edge software has become a cornerstone tool for researchers, clinicians, and institutions worldwide studying speech disorders in conditions ranging from Parkinson's disease and multiple sclerosis to progressive supranuclear palsy and beyond.
Today, DYSAN serves a vibrant global community of researchers, clinicians, and institutions advancing speech pathology research through innovative acoustic analysis. Whether you're a seasoned researcher, clinical practitioner, or newcomer to speech pathology, DYSAN provides validated research tools supported by an active international community advancing neurological health through speech analysis.
