I'd be kind of surprised if people who have internal monologues need an inner voice telling them "I'm so angry, I feel like throwing something!" in order to recognize that they feel angry and have an urge to throw something.

I can recognise that I'm angry without the voice. When I'm angry, the inner voice will often be saying unflattering things about the object of my anger; something along the lines of "Aaaaaargh, this is so frustrating! I wish it would just work like it's supposed to!" Wordless internal angry growls may also happen.
