Play original sentence & your own voice recording back to back

I’d like to be able to improve my speaking and mimicking ability by being able to play my recording that was recorded on the software, and then being able to play it line by line with the captions.

I don’t know how easy this would be, but I believe it would be an AWESOME selling point to stand apart from the likes of Duolingo.

I used to learn Spanish by playing an interactive product by the BBC Languages department, and it was fantastic.

It allowed me to play the role of any given character, hear them speak, record after him/her, and then hear my recording line by line when that particular character had his/her turn.

Would the CEO consider this?
