Forgive me for being a bit too simple on this subject - wouldn't having a liquid in your lungs, throat and mouth really make it difficult or impossible to talk?

Not sure using it for diving or space travel is a great plan if that's the case. Sure you could have a text or flashing lights method of talking but there's no communication method faster than yelling "HELP!" into your radio that I can think of

Divers don't talk that much, actually.

See, there is an air intake in your mouth - and trying to talk under water does not exactly result in the noises you expect when you're talking into air.

The sign used by divers to alert others is banging your knife against the air tank. There are actual hand signs for 'I'm in trouble' or 'I'm out of air'.

Fair enough, like I say I'm not familiar with the subject but curious. I was more picturing the masks that look a bit like gas masks that have radios in them. My extent of diving knowledge is limited to movies and Mythbusters, I'll admit.

Thanks for that information :)

Sign language is the answer.
