Try using the following techniques which helped me reduce blocks too: Extreme pronunciation: you stretch out the word and say it. Speech modulation. You can use high pitch or low pitch voice. Example:- amer( low voice ) ICA (high voice) Skip the first syllable or replace it. Like if you get blocks at a world like’ cat ‘. Just say- so this is a gat/acat. And most importantly don’t forget to smile:) everyone gets stuck once in a while. 80% of the population fears speaking more than death. So don’t worry. I hope the above tips will help you:) all the best for your future
