Would it be wrong for a human/trainer to understand what most pokemon are saying?

Unfortunately I'd say no to the idea. Itd be ok being able to read their emotions and discern some minor details from that. It'd be like a pet dog, after a while you start to get an idea of their personality and who they are. So while you won't understand what they are saying as in human words, you could understand their emotional state etc.
