Oh, okay I see. I quite often get a repetitive stutter, for example the word paramount, I’d stutter on the first part, para-para-para... until I’d run out of breath. What works for me here and what might work for you is I restart the sentence. I take a deep breath and say the sentence over again but this time I really try to focus on speaking calmly. This might still look “weird” but I prefer this technique over being stuck for all eternity. But as always, you gotta find what works for you :)
