I'm aware that there are certain websites around that provide recorded examples of English words pronounced in different accents/dialects. Could anybody list some of them?
Oxford Dictionaries has sound recordings of all its entries.

Sounds Familiar (from the British Library – for British accents)
Without question, Accents of English from Around the World is the absolute best at all this. It provides both narrowly transcribed IPA and full sound recordings for around 40 different English dialects from all over the world. However, it only covers about 130 different words. Still, that’s over 5,000 recordings, and one can infer many more. But it is a completely fascinating site, the best for this I’ve ever seen. And no, I have no connection with it.
That said, I wouldn’t believe the excruciatingly annoying ‘Valley-Guy teen’ rising intonation pattern for the putative speaker of General American, where every word (apart from hundred) has a perfect fourth ascending, no matter its stress pattern. The Chicago version is much more normal in this regard.
