Using the general N64 decompressor, I got a-ton of MP3 audio sounds of the game's voice-acting.
Some of them are a bit corrupted, I think? There's a huge library of over 400 + sounds. So there it'll be a bit hard to find any corrupted sounds/voices.
In general, samples that use Conker's voice seem to have odd artifacts on them. In-fact, they seemed to be sped-up. Which suggest that the game itself may be able to change pitch and speed of certain parts of voice acting.
I would post a zip of all the audio, but it's over the max file limit, as it's around 20+ MB when zipped.
I like to make models in my free time. I also make weird games, too.
You could divide it in smaller parts, or even put them in categories (conker voices, enemy voices, NPC voices etc).
As for the samples being high-pitched, it probably is a technique to save cartridge space. A sped up sample has a smaller duration (which means smaller file size) and can be slowed down with effects to restore its intended speed and pitch.
I made the Don sound rips have named titles for reasons, I guess? I also put any multiplayer related text with (MULTI) at the end. Had to split it in two parts because too big.

I don't have any rips right now, because I'm now re-organizing them.
Also a fun fact: These's audio files may of been recorded from Robin Beanland's (If you don't know, he composed the music of Conker) computer, since it's referenced if you look thru the file as a text file. It also shows that they may of been recorded sometime in 2000.
