I Have Trouble Speaking Words (Not Major Stuttering or anything close to it.I do have occasional stuttering) I just joined this group. Just now a Lady asked me directions to a nearby skin clinic.I'm living in Kerala,India. My native language is malayalam (മലയാളം). Its night here and i couldn't properly talk to her or give her direction (I gave her direction but it wasn't proper or I COULDN'T SPEAK like words that i wanted to pronounce).It could be do to surprise. I know its not a big deal Still this is the worst encounter I've had till this date. And i have big trouble in speakig words that start with A - അ ( The A in Apple) A - എ ( The E In Elephant....like the pronunciation of E in Elephant,Ecuador) 99% of the time it happen when ispeakk malayalam It barely occurs while im reading English or saying words in English. I just get stuck...like mid conversation.....with my mouth wide open and my eye shut..sometimes i use my hand or shoulder to cover my face while being stuck for the other person to not see it. I'm relatively new to reddit too... Pls...reply if you can...
