This would have made Meowth more valuable, but to better limit this resource he could only understand the language of certain pokemon, for example only those with whom he shares egg-group, since it would not only be a guptural exchange, but also It would involve body language and infrasonic.
To better explain this I would recommend a very good manga that deals with linguistics and the limitations of communication between races and species.
