Summary

This study tested a small vibrating device worn on the neck to see if it could make speaking easier for people with spasmodic dysphonia, a rare voice disorder. Forty participants used the device at home for 20 minutes a day over 8 weeks. They reported how much effort it took to speak and how their voice quality changed. The results suggest the device may reduce speaking effort, but because the study was small and had no comparison group, more research is needed to confirm the benefits.
