I think it depends on the vocalization of who's speaking. I've heard many annoying voices within the same languages that I'll also find very apealing depending on the woman. For instance, I've heard some British girls who've had amazing voices come across my ear yet, others from that same country were like nails on a chalkboard. Certainly not to offend the Brits, the same goes for here in the US or Eastern Europe, etc.
Yeah, I met a girl from Prague who made make you melt with her voice. Although she was the most unattractive person. Yet there was a girl who was an absolute knock-out yet her voice was incredibly squeaky and annoying.
I would have prefered the lady with the nice voice, at least you could shut your eyes. With the other, you have no choice but to listen to the squeak.
