There is a physical pleasure for me in certain accents in Spanish, but only when spoken by certain individuals with nice speaking voices. It could be any accent, really, Andalusian, Castilian, or Caribbean usually, in my case. For obvious reasons (obvious to me, I mean) women's voices give me this almost erotic thrill more often. All this is purely subjective, of course, so there is no point in arguing with me about this. I doubt you could convince me that I don't like something that I do, in fact, like.
The last time I experienced it was in a woman introducing a lecture that I listened to on my ipod, from the Fundación March. I don't know who it was, probably Lucía Franco, the director of lectures there.
Why wouldn't you listen to that and try to imitate it, that beauty?
