I noticed that the more I speak, the less I stutter and with words I avoid or block, the more I say them, the less I stutter on them so I now enjoy talking to people on the phone. For example when you meet people on dating apps, rather than text all day, ask for a phone call and get to know each other that way. Start getting your friends used to talking to you on the phone. Now I enjoy phone calls and recently I talked for 10 hours on the phone. I guess the goal is not to avoid but to face it head on and I’m recently learning to animate my voice and in corporate breathing techniques. Sometimes taking a deep breath before certain words I block on really helps a lot.
