In a similar vein: http://www.adultswim.com/etcetera/choir/

The most interesting thing about this one is the chord progressions it generates.

If you enjoyed that, the developer, David Li has a lot of other great projects: http://david.li/

The same team did a squishy Morty head for Adultswim. http://www.adultswim.com/etcetera/elastic-man/. Chris Heinrichs (Dolphin Club Audio formerly of Enzien Audio, https://dolphinclub.website/) does the procedural audio models.

In a historical vein, the absolutely magnificent Voder, from the late 1930s:

I found it difficult to tell how well it's actually speaking because the announcer is priming the audience for every utterance. Very cool though!

After your comment, I muted the audio when the announcer told the audience what the computer would say. I couldn't get it straight away, but when they emphasised different words in the sentence I could usually tell what was being said "Greetings everybody!".

If you're interested in chord generation, I've used Cthulu[0] by Xfer records to experiment with chord progressions quickly.

Cubase Chord Pads are also pretty sweet!

Praise Him.

I didn't expect that to be so beautiful.

You’re right, the progressions are beautiful! Do you know how they are generated?

Very impressive indeed. I dug around and found his tweet: "uses a neural network I trained on choral pieces to generate the harmonization for your melody"

Man, shoot. I compose a bit myself and am really into vocal harmony and I was hoping that he'd hard-coded some theory rules.

I did notice that it seems to vary with the past 3 notes you've moved to. If you continue repeating the same pattern of jumps among the scale, you can replicate the chords the voices slide to.

Would you find this useful? Is this not already available somewhere? Sounds like a fun project!

Yeah, I think I'd find it useful- I'd love to be able to ape a few of the tricks that the four voices use to slide to pleasing chords. The music theory "rules" are certainly available, but only in the same sense that the rules of calculus are available somewhere.

Either way I agree, definitely a fun project.

that is incredibly satisfying to play with
