my question is whether you can take character sound files from,say icewind dale,and put them in bg1&2.anyone know?cause icewind dale has the best sound files of the three games i own.
where else can you find lines like:"well,looks like i'm going to have to go on a killing spree."

yes, you can make any custom sound files you want. I think the ones you mentioned are already prepared into the BG format and can be DLed on www.fileplanet.com.

Here's the instructions for making your own sound files:
Custom Sound files

The following is a list of the WAV files for the custom sound sets. Replace each 'XXXXXXX' in the filenames with the name of the sound set (MAX 7 CHARACTERS). All the WAV files should be 22 khz, 16 bit mono sounds. Copy the WAV files to the sounds directory located in the directory that Baldur's Gate was installed in, and then select this sound set either in character creation or in the "Customize" button off of the Character Record page. For multiplayer, merely send your custom sounds to all of the people you are playing with and have them copy them to the Sounds directory - if you have installed the sounds to your character in your game, everyone will hear your sounds once they copy them into the correct directory.
