That bit of information would have been appropriate in your first post. You were, and continue to be, vague about what you have actually done to get into this fix. If your thread is going to require digging for nuggets of information in order to help you while being laughed at for telling you things that you already know but did not bother mentioning, then, well... "Homie don't play dat."
Sorry,I didn't mean to offend you. I do suppose I was too vague. Here are the key points:
1) Follower begins as a captive, you rescue him, and he feels indebted to you and follows you
2) He was constructed following (with some changes) this guide and prior knowledge http://www.gamesas.com/index.php?/topic/1011099-tutz-companionfollower-tutorial/page__p__14624433__fromsearch__1entry14624433
3) He exhibits proper behavior (greeting, followed by choices like view inventory and follow/wait) immediately after the rescue, and for a short time after
4) I noticed after about an hour that when I talked to him, his greeting shows up, but stays up indefintely until reload
5) I voiced him, but my voice does not play; only the words show up and stay up
6) All other people's dialogue is normal
I hope this helps, and sorry again
