I don't hear any voices.

Well, I definitely work things out in an unspoken voice. Especially while typing something like this. I think everyone does, but I'm not sure if everyone is aware of it or not.

It's perhaps more apparent when you're learning a second language and you have to figure out what to say in the new language.

In fact, I think to myself so much, sometimes I'm unaware if I'm speaking out loud or not. Sometimes I'll look up from something I was pondering and wonder if I spoke it or only thought it. And vice versa, I sometimes wonder if I actually said something in an audible voice or if I mumbled or only thought it.

At times though, I don't use my inner voice, I just accomplish what I'm doing by doing it, but it's usually automated type tasks.

I often lose track of time by thinking to myself so deeply and then when I snap out of it, I have no idea how much time has passed, be it 5 seconds or 5 minutes. Perhaps I can think to myself rapidly enough that the time is 'slowed down' compared to the time it would take for me to actually say the words out loud.

All in all, it's an interesting topic, I'm sure I'm strange somehow, my inner voice is slightly different than my physically uttered voice, and I think you're right. It was set at a different age and doesn't change even though our vocal cords do.

I have conversations with myself all the time but I have never considered your question of how my inner voice sounds. In just the few minutes of inner conversation I have had since reading this post, I have come to the conclusion that my inner voice sounds just like me. I cannot perceive a difference between the two.

Ya, I did that when I read your earlier comment, before I even posted. I cannot tell a difference. It could be a lack of perception on my part, or it could be your hearing (though John agrees with you), or it could be the fact that being a girl I didn't experience a voice change in adolescence like you and John would have and your inner voices still reflect your younger selves?

My inner voice sounds a lot more southern than my spoken voice. I often find myself talking to myself internally and it sounds like my roots rather than my long-removed self. Sometimes that southern part of me comes out, and though it is not a conscious effort to sound more standardized-- my outer voice is not nearly as 'drawled'. Maybe it does come from other formative years. Marina's observation about it being because men go through a voice change is interesting-- and I think it has something to do with it-- but it is not about physically developmental changes-- I submit it is more about psychological development and changing or developing who we really are. Any way, I saw this posting on another blog (a fantasy golf blog) and I thought I would share it:

The Hillbilly's Ten Commandments (posted on the wall at Cross Trails Church in Gainesboro , TN. )

(1) Just one God
(2) Honor yer Ma & Pa
(3) No tellin' tales or gossipin'
(4) Git yourself to Sunday meetin'
(5) Put nothin' before God
(6) No foolin' around with another fellow's gal
(7) No killin'
(8) Watch yer mouth
(9) Don't take what ain't yers
(10) Don't be hankerin' for yer buddy's stuff

Now that's kinda plain an' simple, don't ya think?

Y'all have a nice day.

If perceived ideas are not physical objects, whether or not these ideas resemble the physical objects to which they are believed to correspond in some sense, they are at any rate distinct from them.
The above statement would seem true for inner voices unless the inner voice is a strictly physical event. If it is strictly a physical event then the brain becomes god. An inscrutable god, but god no less.
