What is the French parle pas ta in English?

"Parle pas ta" in French doesn't make much sense on its own. It might be a shortened or informal version of something like:

* "Parle pas comme ça" which means "Don't talk like that"

* "Parle pas tant" which means "Don't talk so much"

* "Parle pas de ça" which means "Don't talk about that"

Without more context, it's difficult to give an exact English translation.
