ACURES: Acoustic and Respiratory Parameters for Dysarthria Assessment

The goal of this observational study is to describe speech and breathing patterns in adults after acquired brain injury (ABI) and understand how these patterns relate to the presence, severity, and type of dysarthria. The main questions it aims to answer are: * What changes in voice and breathing are observed in adults with dysarthria after ABI? * Can combining acoustic, respiratory, and clinical assessments help identify dysarthria severity and subtype? Participants will: * Have their speech recorded to measure voice and articulation features, such as pitch, clarity, and the ability to sustain sounds. * Perform breathing tests using a spirometer to assess lung function. * Complete the Frenchay Dysarthria Assessment-2 (FDA-2), adapted to Spanish, to classify dysarthria type and severity. About 97 to 101 participants will take part. The results will help speech therapists better detect, evaluate, and treat dysarthria in adults after brain injury.
