Apologies to the pun-averse!
Just appending to a previous post (Joining the Ear Force) where I mused about the value of focusing on pronunciation as a way to develop listening skills rather than as a way to improve speaking skills. In a happy coincidence, Delta Publishing just posted a helpful document by Jonathan Marks called "Pronunciation for Listening". It's a free download based on "The Book of Pronunciation", his book available through Delta, of course!
Delta also posted Teaching Spoken Grammar", a related topic by Ken Paterson.
If you're not on their mailing list, I recommend signing up! Delta offers lots of very informative free downloads. I like their offerings because they are often in alignment with a materials-light approach to teaching.
