I will slay you, my enemy.

"There's a bathroom on the right" = "There's a bad moon on the rise"

HA! I thought it said "I will play you my game". Silly 1980s sound bytes.

The original 1980 BK speech is pretty crude and low-rez compared to today's tech alright. 'Slay' sounds like 'play' even if you've heard it a thousand times.
And how they turned 'again' into 'against' wasn't very good either, the 'st' sound on the end is very weak. 'Three' sounds like 'th-lee'. "Fight again th-lee enemies". XD

The original BK vocabulary:

To save ROM space, for example "fight" and "right" are made by replacing "n" from "knight" with "f " or "r". "Slay" sounds like "play" because "s" needs a good high frequency response, which the old speech board couldn't afford so it is a bit muddled.

Anyway, clever programming to synthesize many new words by re-arranging the samples!

And I just can't keep myself from reading this topic aloud in deep voice: "WHAT - DOES - THEE - BLACK - KNIGHT - SLAY"

All good points. I would add that it is hard to get the critical high and mid frequencies to your ear when it is playing through a single speaker facing the floor.

And a carpeted floor. I think I'll try temporarily connecting a smaller speaker behind the grille that is under the head just to see how it sounds. I got lots of leftover transistor radio speakers I could play around with.
