The first call for papers for International Congress of Phonetic Sciences, the phonetics olympics! Due February 1, 2015. It's only every 4 years. This year it's in Glasgow. It's always a really nice conference with a great set of people attending. There is also a decent amount of phonology and people with phonological interests who attend. Edinburgh folks are involved, so there's definitely going to be things on sound change/modeling of it.

and a great plenary speaker lineup
There's also satellite workshops, including, so far, one on developing an IPA like system for prosodic transcription.
See the previous ICPhS (2011) for its program to get an idea:
