There's a theory that astronauts may be able to communicate in space without their radios by touching helmets together. Don't know if it's ever been tried.

And speaking of touching helmets, I can imagine another version of this comic where Bob is making a sexy scream, instead.

Searched a bit and surprisingly couldn't find any agency communication about this. I found that they use some gestures though.

I saw somebody do the math and say that this method would dampen the voice so much that it might as well be said not to work. But I don't know much about this topic, and I can't say whether the math is correct, either.

I mostly brought it up because it was interesting and let me make a joke about "touching helmets".

Maybe some special physical interface could be built in the helmet, but if space agencies never came up with a solution for this, it probably means it is not needed.
