VoxMetria - Vocal Quality for iOS

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 clients 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 clients 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).Its 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).
