DAF apps [delayed auditory feedback]

DAF apps [delayed auditory feedback] Alright who’s tried this? You can download apps that function like a speecheasy device but they are free or only cost a few bucks. I’ve tried it a few times and I think it does work, but you have to have this app running on Bluetooth headphones so it’s not very practical. The funny part is, if you don’t stutter already, using the apps *makes* you stutter. My boyfriend tried it and cracked up laughing when he heard himself stuttering. It’s wild. the effect wore off quickly the more he talked. But he did say it gave him a little taste of what it’s like to have a stutter. I suspect the effect would wear off quickly in its intended use for stutterers as well. Any experiences to share??
