Mere intelligence does not provide for knowledge of languages unless you actively pursue this learning. With your intelligence I surmise the curve to learn them would be lower but it is not automatic.
It's been a long time since you created your character, how come you've never asked this before?
Perhaps this is something you can incorporate into development and/or CDQ, but I can't just say "Yes you're smart, you should know halfling, drow and dwarven."
