Communication is only possible when you agree on the meaning of signs in the messages you exchange. You need human language regardless whether you have neural i/o channels or use sound waves to communicate.
While some humans do use gestures while they communicate to add more bandwidth there seems to be little pressure to go for more bandwidth by evolving a system of more elaborate gestures when you are able to speak with another person.
The part of language that’s about thinking to how abstract words relate to meaning seems to be more import than adding more i/o.
