I love this website! Simply type a word into the search box and it tells you how to pronounce it. Of course, I don't like to take it too seriously because the pronunciations are utterly RP, but I do find it a useful guide to words I'm unfamiliar with ('calque' for example. )
Once you've typed a word in, it provides an alphabetical list of the available words which surround it, and I've spent some happy times simply browsing through the various words on offer. (As a bonus, the fella providing the pronunciations sounds just like Clement Freud - to my ear anyway.)
The only real objection I have to it is that I think its name is anomalous to the tone of the site. 'How Does One Say' would be much more appropriate.
I can't believe it. Epicaricacy, and it's pronunciation is there. I am impressed!
