When people think, naturally it’s in their own voice. It’s because our “vocal” thoughts are linked to the same muscles that produce speech. We know exactly how we sound without even having to say the words themselves. They’ve simply been heard too many times before. But the question is, if I wanted to adopt someone else’s voice as the narrator of my thoughts, would I be able to?
This would mean that one would need a level of familiarity with that other voice akin to his/her own. So how would someone be able to achieve this level of understanding? Well, there is a way. You find the person whose voice you wish to adopt as your mental persona. You then NEVER speak again. (Well, not for a long time.) This other person must surround you and your life. You must be able to hear this person’s voice, and learn every vocal inflection possible by this person. Their sad voice, angry voice, happy voice, and even the more discreet emotions, such as the “I need to poo” voice must be yours. Eventually, you will forget your own voice, and your mind will have no choice but to adopt the next person’s voice as its vocalizer. (I made this word up.)
Of course, it’ll help if you actively try to “think” in that person’s voice. And slowly, but surely, you should be able to take that person’s voice as your own. Eventually, you’d be able to speak again, but you’ll need daily refreshers of “that” person’s voice, lest your mind try to reclaim its original persona.
Just imagine, being able to narrate your thoughts in a voice different from your own! It would be bad ass. If you managed to take a particularly hot voice as your own, you could think thoughts such as “I need to poop,” and it would still be awesome. And hot.
