There are not that much of publicly available sound dictionaries, understandably (and unfortunately).
You might start with web-based online dictionaries with sound. For example, one of the web-based dictionaries is already configured with GoldenDict, it's a Google En-En dictionary, it contains sounds for many words. Naturally, there are many more such web-based dictionaries.
Another good alternative is to use Forvo web service, you could configure it in Dictionaries Settings, Forvo tab. Forvo provides pronunciations in many, many languages (including all major ones). I use it regularly and find very useful.
