Reading aloud, does it help? Oui

I have been promoting reading aloud as a tool for higher level language acquisition, better articulation, pronunciation and increased confidence. But does it work? In liaison interpreting, after doing it myself quite intensively for a few weeks, and having had a session today, I would certainly answer with a frank and unbiased yes, it does. To what extend and at what level? That's what I want to focus on in the coming days.
