Multi-Dimensional Voice Program, Model 5105
Introduction
The Multi-Dimensional Voice Program (MDVP) is the gold standard software tool for quantitative acousticassessment of voice quality, calculating more than 22 parameters on a single vocalization. Based on extensive field testing with normal and disordered voices, MDVP™ is unique in its ability to workaccurately over a wide range of pathological voices. Its normative references are based on an extensive database of normal and disordered voices; and results are graphically and numerically compared tothese normative threshold values. MDVP quickly and easily provides a revealing snapshot of voice quality.

The Need for MDVP
As revealed in the professional literature on voice analysis, one or twovoicing parameters alone (e.g., MDVP provides graphs and numerical results to summarize voice parameters. Patient results are only jitter and shimmer) are not plotted against a normative database.sufficient to accurately describe an aberration in a patient’s voice. Jitter analysis and perceptual attributes of a voice can be fully values may be within normal limits in a patient who explored with theDisordered Voice Database, Model 4337, demonstrates a breathy voice quality, and periodic modulation which contains MDVP results and audio samples from 700 over many glottal periods (tremor) should bedifferentiated patients. from cycle-to-cycle modulation. Similarly, turbulence caused Easy to Use by incomplete glottal closure can contribute a different type of MDVP is designed to be quick andeasy to use.
