I think it would be nice if the speech bubbles for talking could change in some slight ways depending on which channel of speech you're using. Primarily, I'm thinking this should apply to radio, since I can't count the amount of times that I've been talking on the radio in a public area and someone near me stopped what they were doing because they thought I was talking to them. Maybe changing the ... on the sprite into either a /// or a ::: could be a solution without damaging the aesthetic of the different species speech bubbles.
