Whatever you think up online — it’s already been done. I’m working on my pronunciation, and I need to hear what I say through my own headphones. Pressing record and play a hundred times will drive you insane. I found a website that returns what you say immediately as soon as you stop. It learns the rhythm, and if the phrases are roughly equally short, it works great.
Then you open something like https://www.youtube.com/watch?v=Rui0QywfrdY (randomly picked on YouTube just for this post) and repeat after the speaker, creating this cycle “reference -> pronounce – listen to the result -> reference”. It’s ideal to sit in good isolated headphones with noise cancellation, so that nothing but your voice gets picked up by the microphone.
