Computer-based analysis systems are increasingly available for the clinical assessment of speech and voice functions. These systems have the potential to provide immediate quantitative information to assist clinical assessment and treatment. The Multi-Dimensional Voice Program (MDVP) is a computer program that can calculate as many as 33 acoustic parameters from a voice sample. The MDVP appears to have potential for rapid quantitative assessments of voice in both research and clinical applications. This report evaluates the robustness and reliability of MDVP for vocal analyses of 32 individuals with dysarthria of various etiologies. It is concluded that the reliability is generally very good and that MDVP has potential as a tool for the semi-automatic analysis of voice samples in dysarthria. Some parameters appear to hold particular value in the description of voice qualities in these speech disorders.
