Differentiating upper- and lower motor neuron diseases using automated acoustic analysis
Abstract
OBJECTIVE: Motor neuron diseases (MNDs) result in a spectrum of motor impairments, including considerable effects on speech function, which manifest as dysarthria-a motor speech disorder. Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in …
