I don't, unfortunately. Just the usual techniques. Take your time, and speak when you exhale, not when inhaling. Speak gently and prolong your sounds and words if necessary. Say you stutter on "speech," and it's an issue at the start. You can ease into it by going "ssssspeech." Sometimes, focusing on your words can help, and sometimes distracting your mind or having a blank mind can improve speech, in my case anyway. These things don't always work, but they can do. It does also help to stay hydrated and remain positive and as confident as you can be but it's harder than it sounds. When you stutter, don't rush into it. You can pause, collect yourself, take a deep breath and try again. Don't rush it. Deep and slow breaths can help, as long as you're not struggling for air. If your heart is beating quick, slow and deep breaths should work to relax it and help you. People have claimed to become fluent after struggling with stuttering and others have claimed to improve with a mild stutter left. There is hope we can all overcome this. People believe it is a mental problem and it's to do with subconscious fears and anxieties. A speech therapist or even a regular therapist should be able to help if that's the case. Everyone is different so results may vary. Hopefully, these tips can help. They may seem simple but it takes time to get a hang of them and do it naturally.
