Incidentally the Dalek voice is an effect that can be accomplished really cheaply in hardware or software, called a ring modulator:

There are a handful of Dalek effects for the Teensy/Teensy Audio platform:

Teensy audio board is here: https://www.pjrc.com/store/teensy3_audio.html (heads up, there's a rev D board to use with the Teensy 4, has the same functionality but different pinouts to match the Teensy 4).

I have a friend who is very handy, very into building vintage stuff. Cars, bikes, etc. One day he rang on some unrelated subject, I could hear he was on the motorway, I asked him where he was going.

"Oh I'm just off to get a voice box for my dalek". Like that's the most normal thing in the world.

Sure enough, next time I visited, a certain iconic malevolent alien, that fears only stairs, was sitting in the corner of the garage, happily murderously chuntering away every time he pressed the button.

Reminded me of the Vogans from the original radio show of Hitchhiker's Guide to the Galaxy. But that might just be my memory playing tricks.

Agreed, the Borg voices are much deeper and certainly aren't don't have a British accent.

This is very spot on, especially if you use some standard Dalek lines. A good example to test: "The Doctor is detected: terminate, terminate! Seek, locate, destroy."
