I have a really hard time pronouncing words that are not within the standard set I use in most day to day. In some cases, someone can say the word or name to me and i cannot reproduce it. I also can’t hear differences or reproduce many music tones. If you play a few notes, I can’t hum them back. I suspect the part of my brain used in sound identification and reproduction has a very low “iq” relative to the average. I find it pretty stressful when I’m meet someone with an uncommon sounding name, as I worry they will take offense and I really don’t know what to do. I practice the names offline in the hopes of learning them.
