Does any animal's voice pitch depend on its sex?

Are there any other animals apart from humans whose males and females have differently pitched voices?

I know there are lots of birds and insects, and I think, even some mammals whose males sing, while females don't. Insect females are mute then, I suppose. Anyway, their voice organs are not in their mouths and they often look quite different too. But when birds or mammals are just calling, not singing, can you tell their voices apart?

Why do I become hoarse if I shout? And how does my voice recover?

Is it possible to speak normally through a mixture of Helium and Sulphur Hexafluoride?

Helium makes the pitch of the voice rise, Sulphur Hexafluoride makes it go down. Ignoring the question 'Why would anyone want to?', is it possible to make a mixture of Oxygen (and possibly Nitrogen), Helium and Sulphur Hexafluoride so that when you breathe it in, your voice sounds exactly the same as if you had not? Has anyone done it?

Does wind have any effect on sound waves?

Can your voice really be "snatched" away by the wind, or is it just that the sound of the wind covers the sound of your voice. If wind does affect sound waves, can it also affect light?

A chest cold temporarily made my voice deeper (and sexier, apparently). How? Can I get the deep voice without the cold?
