Interesting concept, but I’ve found that when I read aloud, that I’m concentrating so much on pronunciation, cadence, etc that I pay almost no attention to the meaning of what I’m reading. In fact, as a result, when I’m teaching English I have abandoned reading aloud as an exercise for anything other than pronunciation, I go with reading for gist/reading for specific information exercises to highlight grammar, meaning, etc. I’ll be curious to see if there is some response to this and in particular what kind of learners this works for.
I think I get what you say. It is just a matter of practice. After the first few times you practice, it goes better and better. It has been working great for two years with a French friend of mine. Each one takes their time when reading and we are not so strict on pronounciation unless we ask each other to be like that. Main goal is enjoying the story and the language. Probably that is the real key. We both started with a B2/C1 in French-Italian. If you feel you want to try, just let me know.
