I'm the maker, and you're totally right. It would be great if some habits could be tracked automatically. I'll be building a native mobile app soon, and will do my best to remove the friction of logging habits!
Czech pronunciation is extremely regular and straightforward (sounds close to Latin or even Italian) with no weird "which vowel was that" or "half the word is silent" features and just a few exceptions. Usually if you write a letter, you pronounce the sound, and if you hear a sound, you write the letter.
A great example is that — for most words from any language that uses a subset of the Czech alphabet — a Czech speaker can just pronounce the word instead of spelling it and another Czech speaker will be able to write it down.
e.g. "messerschmitt", "nešamas", "cadeira", "philosophy", "tastaturi", "nicchia", "kaupunki", "abordagem", "povjerilac", "primauté" are all foreign words with very unambiguous pronunciation in Czech.
I don't know Czech, but Italian is extremely consistent in the way it's written, so it's at the top of the list with about one or two orders of magnitude less data.
Czech pronunciation is actually very close to Italian (and both close to Latin). We don't do the "ce" and "ci" and "gn" things (we do a "di, ti, ni" thing instead), and we use diacritics to soften certain sounds (ž,š,č,ď,ň), but even ignoring all that and plowing right through, an Italian speaker pronouncing Czech text should be easily intelligible and even spot on for some words.
I'm more impressed about Korean! I didn't even realize it was that good in V2. But I've just seen a lot of systems perform really poorly (judged by my Korean gf not me) and Korea is only a country of 52M (between Spain and Italy).
A funny note, if Siri is set in Korean mode and reads your texts that come in as English, they sound like a racist imitation of a Korean accent. It is absolutely hilarious.
I also find funny how Portuguese is also better than English (Brazilian talking here). I guess is probably the nature of the languages or so, phonetics...
it does works amazing in PT-BR Whisper V2, I can't even imagine it being better, and turns out, V3 promises it to be better...
