The real-time pronunciation feedback is surprisingly smooth, and I love that it corrects you without making you feel dumb about it. Really thoughtful build for ESL learners.
Love how the pronunciation coaching feels integrated rather than tacked on, like it's actually part of the lesson flow instead of a separate feature. Clean UX choice that makes a real difference for ESL learners juggling multiple skills at once.
Tried the pronunciation part for like five minutes and it actually caught a sound I'd been mispronouncing forever, so that was genuinely cool. Feels pretty beginner-friendly too, not overwhelming.
The pronunciation coaching feature looks really well thought out, especially for ESL learners who often struggle with getting real-time feedback on tricky sounds. Clean execution.
