With the GPS system a friend of mine uses you can choose between 15 or so languages (including national differences, for example: UK-US-AUS English, or Belgian vs Dutch Dutch etc). And with all you can opt for a male or female. But for some much spoken languages you can choose between two female voices. One is a more sexy sounding voice, the other one sounds more firm

No such difference exists for the male voice.
You should expect it otherwise, cause female drivers get lost more often
