I have two internal voices. A male named Arron and every once in a while a female kicks in to the conversation. They both trigger panic attacks sometimes or Arron will always use my anxiety such as if I walk down a hall he'll say "Someone's following you. RUN!", and he'll tell me things that can freak me out or get me down. The female isn't as active. The female usually comes when I'm focusing more on the voices.
These voices though are thought like to me. I don't hear a literal voice. It's kind of like reading or a thought you don't have control over.
To answer... mine are both. They have their times were they'll taunt or argue get me down. Other times they can be someone to talk to or they will support me. Make me laugh etc.
I do talk to myself and I will whisper or talk out loud when I talk to them. Mines both.
