Welsh has some odd sounding letters I'll grant you, people who talk on TV for a living should make an effort though, you don't go on stage to do your job tuned to GADG do you... or do you?Yes but it works both ways. It can't be that hard to pronounce right which tells me that either they have a bad ear or unnecessary arrogance/laziness. Lots to know about a person right off the bat! In all fairness though non phonetic mother tongue speakers have it harder than ones that grew up speaking phonetic mother languages. Another fascinating subject....
Sorry I know you don't
