Reddit mentions of Oxford Dictionary: English-Hebrew/Hebrew-English (Hebrew Edition)

You might have a hard time finding this specific of a resource. Most dictionaries will not have the English transliteration of Hebrew words, and certainly not for every conjugation. I recommend learning to read with niqqud (which is explained at the beginning of any good English-Hebrew dictionary) and learning how to conjugate all the different binyanim. This way, you can read the Hebrew word and know how to pronounce it without much ambiguity. If you are not yet at this level, maybe you should start with a more basic introductory text book as opposed to a full-fledged dictionary.

As far as specific dictionaries go, I reccoment the Oxford English-Hebrew/Hebrew-English Dictionary or the The New Bantam-Megiddo Hebrew & English Dictionary, Revised.
