I learned the first word in dead man's respite, went back to hrothgar but boori won't respond .... Anyone help me on this?

On my playthrough, when Boori was supposed to teach my character Wul, Arngier noted that my character already knew the word, then Boori taught the second word instead, and activated Wul for my character. Exiting the game, then reloading the Autosave may reset the sequence. You should (hopefully) have the Autosaves where you entered High Hrothgar and exited again.

I tried that and they all still ignore me...do I need another dragon soul?

http://www.uesp.net/wiki/Skyrim:The_Way_of_the_Voice This page has infromation on the quest and Console Commands to force the quest forward if you are on a PC.

Try activating Wuld with a dragon soul (you can pick one up fairly close to the Atronach Stone along with a word of Frost Breath) and then speaking to Arngeir.

I am playing on ps3..... Here is more info....when I took the mission to deliver supplies to the graybeards, (how do you deliver those btw?), I was taught become ethereal which i can't seem to use. Then I was sent after jurgen's horn. I got all the way to the point where I needed the whirlwind sprint. I read online to get the first word at dead man's respite before going to boori. Did that, went back to boori and they all basically ignore me. Is there something else I need to do to trigger the teaching? I can't do jurgen's quest without that shout. Also, if it matters, I am only a level 12....I really appreciate any help you can give...

Also, I do recall doing some training in the courtyard at hrothgar but to be honest, I was a bit into a bottle of jack Daniels and I don' t remember the details... I passed and was given the Jurgen horn quest.... In my shouts menu, I have unrelenting force, and become ethereal...I equip ethereal and it does nothing...

You should have been taught Wuld prior to being given the quest for the Horn of Jurgen Windcaller, I am not sure how you switch shouts on a PS3.
If you do not have the shout then you probably need to restart your game. If you were trying to get a second shout word for free, then you are not going to get it at this point. Most of the Shouts need a Dragon Soul to unlock and use, Ro, Da, Wuld and Yol are trained by a Greybeard.
Whirlwind Sprint is the last shout in the menu, have you scrolled down far enough?

The delivery package gets placed in the Boss chest at the entrance to High Hrothgar. You activate the chest and place the supplies into it. This is one of the highest paying fetch quests in the game.

I had to start the game over... Thank you for all your suggestions....much obliged!

Lol!!!

I've been there. I killed the Enchanting guy at the College. I was well into a 12 pack and was aggro because he wasn't helping to kill the ancient dragon that was killing me repeatedly. So when I finally did kill the damn thing, I walked up to him, poisoned my ebony fire-bow, and shot him right between the eyes. Bad idea.
