Research for a presentation turned into me finding SpeechEasy

Research for a presentation turned into me finding SpeechEasy For a presentation, I chose to inform my peers on what a stutter is. This is because on the last presentation we had, all of them minus three had negative comments about my stuttering. Some were mean about it too. Afterwards they all understood and some even apologized for their comments. While researching, I found SpeechEasy. It’s really expensive and everything that I have read about it is good. And I am just wondering if anyone has ever used these devices. And if you have, did it help?
