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.
There's some interesting discussant sessions:

and a great plenary speaker lineup

There's also satellite workshops, including, so far, one on developing an IPA like system for prosodic transcription.
