There's now a JavaScript API worthy of your attention. The demo code has been moved to https://github.com/dhdaines/soundswallower-demo, and has been updated to be all "modern" for whatever that's worth. No, it's worth something, because asynchronous JavaScript is genuinely cool. Also of note, JavaScript *defaults to float32 input* because that's What the Web Wants.
A major bug in the Python and C API was fixed which broke long utterances such as used in ReadAlongs. The documentation has also been greatly improved, go see it at https://soundswallower.readthedocs.io/
Also the default acoustic model is now the narrow-band one, so as to be more robust to whatever crappy audio you throw at it, and we include also a French model (qui marche plus ou moins au Québec, désolé).
