In my opinion though you'd be better to spend just a little time learning to read Hebrew. For the first year of learning Hebrew I didn't bother with learning to read and it was a mistake.

Once I could read read I started to recognize the Shoreshim (root letters) as part of words and, from there, all sorts of patterns became apparent and I could start to infer meaning from context and the shoresh.

Hope the link helps.
