I still stutter of course, but the amount has SIGNIFICANTLY dropped. I’m almost fluent of course I still get blocks here and there. But it helped me so much! How it works is it replays your voice at a different pitch & slower. It’s very interesting. It’s not a cure by any means but it definitely helps a lot. I don’t always wear it mostly when I’m on dates or have an important meeting only because personally it bugs a little & looks like a hearing aid.
