It’s very frustrating if you’re afflicted with a stutter, as people don’t appreciate how hard it is to make yourself understood. Speech therapy can work, but it does take a long time, so being able to train on the go is a very helpful idea. Hollins Communications Research Institute have developed an iPhone application which lets stutterers measure their fluency. You can record audio files and then check how understandable different phrases are, as well as practise words till you achieve the desired fluency level.
You can also email the audio clips to your speech therapist for them to analyze, as it gives them a clearer to picture of what you need to work on. I think this a fantastic app as it has the potential to really help sufferers.
