Everything in the game is procedural — synthesised footsteps, breathing, ambience — except 14 recorded voice lines. This page is every one of them: who says it, the audio file, and exactly what makes it play.
Recorded vs. synthesised. Grump's ambient mutters (see Grump's Questions) and every one-off sound effect (dings, thuds, stingers) are synthesised with Web Audio, not recorded. Only the lines below are actual voice recordings.
Press play to hear each line exactly as it plays in the game. (The clips are Ogg Vorbis: they play in Chrome, Edge and Firefox; older Safari may not play them.)
