I have a stutter. Years of speech therapy as a kid did very little to solve the problem. The only thing that helped somewhat was a device called the "Speakeasy". It looked similar to a hearing aid, and essentially played back what I said to me. The insight was that when people who stutter speak along with someone, they tend to stutter less. I've also noticed I don't stutter at all when singing along to a song. It kind of ties in with this study; your brain knows exactly what speech to form, so the "weak" connections are sufficient.

Really happy about the progress being made in this field. Stuttering has been both a cause and result of my social anxiety, which people often mistake for aloofness or worse. Can't wait to try new therapies!
