Coincidentally I tried the python client just earlier today and was blown away. I never even had to record my voice, I just typed two words for the wake word and it was 95% accurate in picking them up even with heavy background noise.

I am definitely going to integrate the wake word functionality into my Chrome extension that lets users control the browser via voice (https://www.lipsurf.com) so they can turn on the extension without even hitting the button.

I thought I would need to look into compiling into web assembly myself, super impressed that this too has already been done.
