Looks really neat! I'd love to be able to click on the individual words in the report to hear back how I said it. Also I'm a native speaker and I'd argue with the errors I got :). I think in each case they're valid alternates in rapid speech. Most of the reported errors were for vowel substitutions, where I used a weak form (schwa) instead of the corresponding vowel-as-written. E.g. [əktɪvɪtiz] instead of [æktɪvɪtiz] for activities. (see https://www.youtube.com/watch?v=EaXYas58_kc https://www.youtube.com/watch?v=EaXYas58_kc) Which (now that I think of it) you already get right in some cases, e.g. for the second "t" there — in my American accent that's flapped and there was no alert raised.
