Without playing the game I let it Run on so that the sampled speech can be heard. These are good quality (quite clear) samples - I wonder what hardware/software combo was used to make them?
Please note that due to a hardware issue the sound gradually slips out of sync but this problem is specific to my capture device - NOT the game.

It was captured with the 464 tape deck after being recorded with a microphone into another boombox type tape deck. The samples are 1 bit.  Although clear it doesn't actually sound like me due to the low quality.
