Just like the Laugh option, Chara gives an account of what we did, that didn't actually happen.

The only words Chara tries to put in our mouth are words we didn't actually say. And the second time, Chara just says that herself, without sayhing that we said it.

None of those confirms that Frisk was able to talk to Chara. She's just noticing he isn't Laughing, or Heckling along with her.
