Women who have high pitched but breathy voice are most attractive while men who have husky voice are more appealing.

“What we found is that for males listening to females, they preferred the voice to be high-pitched – although not too high – and as breathy as possible. These suggest a small body size. Marilyn Monroe would be a very good female example. It makes sense that females don’t like a male who is totally aggressive. The pitch indicates masculinity”, lead researcher Dr Yi Lu said.
