Duolingo has dropped hugely in quality (for Korean anyway) just in the last couple months. The AI-generated voices mispronounce so much stuff. I spend more time reporting unclear audio or outright mispronunciations and grammar issues than I do learning. They seem to want their users to be their QA team, but then don't even fix the reported issues. https://www.msn.com/en-us/news/other/duolingo-lays-off-workers-as-it-leans-on-ai-tools-to-carry-out-more-tasks/ar-AA1mKgja
