I wonder how much animal body language could help with that. Maybe instead of trying to focus purely on the language (like with human language translation), the algorithm could try to observe and infer the meaning from more than just audio? Dogs were domesticated long ago and can communicate with humans, sometimes purely through "facial" expressions and body movement.

I'd think it would depend a lot on the animal. Whales, for example, don't really have great eyesight. They depend a lot more on sound and have been observed communicating over long ranges (particularly because water carries sound quiet well). So it seems natural to conclude that whales would communicate more primarily through sound than other mechanisms.

That's a great point, didn't think about that!
