Absolutely! How did we learn our native languages? By listening to the audio book of life and without understanding anything at all first. Simply listening familiarizes our brains with the sounds and rhythms of a language, and builds foundations for the new neural pathways we will need to become fluent.

Valen, como aprendiste tantos idiomas?

Not if you're a visual person. but from your question I may understand that you're an auditory person so that listening to an audio book should surely help even if you don't understand anything at all.

I would say yes, especially If you have a script of what it is saying 😁 i suppose the audio will help with recognising key vocabulary and pronunciation

No I will gradually think it something like nonsense music and ignore it.....
