Description
This test can check your voice quality by variations of frequency (Jitter).
Jitter and shimmer are measures of the cycle-to-cycle variations of frequency and amplitude, respectively, which have been largely used for the description of pathological voice quality.
Higher jitter levels suggest that something is interfering with normal vocal fold vibration and the mucosal wave.
Whereas jitter is a measure of the percentage irregularity in the pitch of the vocal note, shimmer is a measure of the percentage irregularity in the amplitude of the vocal note.

Ratings and Reviews
Great!
This app is easy to use and figure out. It tells you what to do for easy instruction. Also gives the results immediately
Potentially good, but it's a work in progress
When it asks to say a vowel, should it be long or short? Why are you asking for name and age? What does "jitter" mean? show me a picture of jitter vs. no jitter. I can't analyze the spectral result so why display it? The help just labels the controls. There is no explanation of what this app is or does.
