replace gamespeech commentary via audy 06

Can anyone tell me a step by step instruction coz i had in-game commentary files for nba live 06 but i dont know how to replace those of the default.i juz dont want the so many audio files that i created be wasted coz i dont know how to use audy 06 or if i need any tools.i tried to replace but i cant find the save button plz help!

I dont really like nba commentaries so i cut tagalog audios from youtube and convert those to wav. But when i tried to overwrite marv & steve commentaries i juz cant get it to work.i had a clean & original install so i wonder why its not working.pls help coz i feel wasted.......super thanks
