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.
