It doesn't work - it seemed to catch my accent once I ran it a couple of times on the same browser, but... in the incognito mode, it fails every single time, ranging from French and Swedish to Swahili. :D When I mumbled a bit and lowered my voice, it said 97% English, lol. Maybe its model treats mumbling as the UK, hard to say. When I added a bit of "R," it immediately recognized me as Russian, ignoring everything else. And when I increased my pitch without changing anything else, it started detecting Persian and Spanish. When I used a proxy server pointing to Scandinavia, it started detecting Swedish, lol. Fake as hell. I'm Polish, btw.
