Make your voice sound like YOU hear it

There are two parts to the sound that you hear when you speak. As well as the vibrations heard through bone conduction there is also the sounds reflected off the environment around you. You can hear what the bone conducted speech sounds like by putting your hands over your ears whilst speaking so that you can't hear the room reflected sounds. Basically it sounds muffled and bassy. This effect can be produced by applying a filter to the audio that cuts off the high frequencies and boost some of the lower mid ones. To replicate the part that the environment plays you would need to record your voice in a room with a directional mic pointing away from your face so that it doesn't pick up your voice directly but only the room reflected sound.
