Maybe this has evolved, but the version of this I was exposed to was in the context of French, where you would play these "ecoutez et repetez" things and the class would say things out loud. Pimsleur has a most likely well-deserved reputation for language fluency training, but I would go a step further.

For me the critical thing is hearing the playback of your own voice and being able to learn to hear the difference. I've encountered this with professional mimics / celebrity impersonators -- the most important thing to do is to hear what your voice sounds like.
