Also, add a tip jar somewhere so we can chip in!
1. The translation is great. I actually never used ChatGPT for translating content and this opens a new world for me.
2. The text-to-speech is good, but less so than the translation itself. It still is completely understandable, but if you are a learner I believe it could cause some bad habits over time. For instance, at around the 30 second mark, the translation includes the word "immergervi" (immerse yourselves). The voice puts the accent on the 2nd "e", while it should be on the first one.
Anyway, great tool. And I would help to chime in for different languages (trying to improve my Spanish). Put a tip jar somewhere as others suggested :)
I often practice by reading sites like https://cn.wsj.com/, https://www.bbc.com/zhongwen/trad, https://cn.nytimes.com/, or https://big5.ftchinese.com/. These are all text news sites so they help with reading comprehension and grammar but not at all with listening. I'm not aware of any similar audio sources, especially not ones that use professional-level language but slow it down so it's accessible to language learners. So you'd be in a unique niche.
Would it be possible to provide an English translation of the Italian transcription? Seeing them side by side would be enormously helpful.
Between Italian, German, Spanish and French I find it's the most difficult language to parse by ear. The lack of pauses between words, the omnipresent en and y, their numerous contracted forms and generally speaking as if they are being charged by the millisecond makes it for an extremely frustrating experience sometimes.
