VoxMetria - Vocal Quality is designed for Speech-Language Pathologists to analyze voice through a phonatory deviation graph showing voice deviation. Phonatory Deviation Diagram is a simple and straightforward graph, which ranks the client’s production inside a normal or altered area by means of a little red circle, which indicates the average value and smaller green circles, which show the irregularity distribution, particularly concerning phonatory deviation; it enables brief and precise information on the quality of the client’s production. You can record a sound and edit the sound file easily! The statistics screen displays the acoustic analysis values of fundamental frequency, jitter, shimmer, irregularity, noise rate and GNE (Glottal to Noise Excitation). It´s possible to send the results by e-mail (sound file, Phonatory Deviation Diagram and Statistics) or export the sound file through iTunes. Note: To use the Vocal Quality Functions, record a sustained vowel for some seconds (preferencially the /e/ vowel) Coordination: Dr. Mara Behlau, pDH *Phonatory deviation Diagram is based on hoarseness diagram method developed by Dr. D. Michaelis (pHD thesis).
