How to recreate missing lyrics?

Hi Udionauts. I have created some songs in a language I don't comprehend well enough, Italian. In the course of editing, extending, cropping etc. some of the lyrics have disappeared, and some are just wrong. I like the music and I'm looking for a way to recreate the lyrics, to find out exactly what is being sung. What would be a good tool for that? (other than an Italian native speaker) Tried the Deepl and Google Translate apps, they can record speech and translate it, but they seem to have problems when it comes to music and singing voices...
