An interactive website for exploring how human speech can be reduced to just a few sine waves and still be intelligible - or at least recognized to be a human voice. On top of that, I've added various ways to make the sound more musical.

The sound effect is based on research from the 80s, which has largely been forgotten by then.

To have the effect run in real-time in the browser, I opted to use Rust compiled into WebAssembly. Still, I had to rewrite some linear algebra routines. More about that experience in the blog post: https://vvolhejn.com/2024/11/16/sinewavespeech-com-live.html
