[RPG] Can amphibious creatures in Pathfinder speak underwater, and if so, how

pathfinder-1e

This is one of those things that seems like it should be obvious, but isn't stated anywhere in the rules, so far as I can find. Can amphibious creatures (read; things that can breath underwater) speak underwater?

If so, how? Can they only speak Aquan, a language literally created on a plane where there is only water, or are any languages viable? Would it work like dolphin speech, or is it like Drow Hand Sign, and doesn't actually use verbal components?

If there actually Are rules about this, stated in the Pathfinder books, please say which book and what page number. If it's something mentioned in fluff or a novel, please give the name of the book.

As noted by DoStuffZ, sound travels faster in water than air. The problem with underwater speaking is that we (human airbreather) need to exhale oxygen to speak, which forms bubbles and alter the sound. If you hum, you'll be heard quite well, so you can try to communicate this way.

I never heard of any official description of D&D / Pathfinder languages, so feel free to houserule that aquan is indeed a way of speaking clearly underwater even for non-amphibious creatures (by humming or very short syllables that wouldn't be altered too much by bubbling).

If you're looking about rules, note than D&D3.5 aquatic elves live underwater and do not speak aquan. Aquatic druid doesn't gain aquan either.

This link to Paizo forums also make a couple of points :

I found this in stormwrack I'm still looking, but this might shed some light. It's for a Bard: "Bardic Music: A bard performing underwater is restricted in what sorts of Perform checks she can make. Perform (sing) is impossible unless the bard can breathe water, whether naturally or by virtue of a spell. Oratory is similarly ineffective."

and

Spellcasting Underwater: Casting spells while submerged can be difficult for those who cannot breathe underwater. A creature that cannot breathe water must make a concentration check (DC 15 + spell level) to cast a spell underwater (this is in addition to the caster level check to successfully cast a fire spell underwater). Creatures that can breathe water are unaffected and can cast spells normally. Some spells might function differently underwater, subject to GM discretion.

This would means that speaking (and even casting spells with verbal component, though it says nothing about spell with language subtype) isn't a problem as long as you can breathe.
