If you're going on a trip to Spain or Latin America - or if you just want to learn Spanish - then this application is well worth checking out.
Talking VOX English-Spanish and Spanish-English dictionary contains a database of around 68,000 words and phrases to help you translate between the languages. The app contains lots of usage examples, grammatical pointers, and native terminology.
Talking VOX comes with predictive text entry, so as soon as you start typing a word, a list of possible matches is displayed. There's even a Wildcard search facility, to help you look up words when you're not quite sure of the spelling. There is a sound module within the program that can speak many of the words to you at the click of a button.
Another great thing about the Talking VOX English-Spanish and Spanish-English dictionary is its 'resident module'. This allows you to look up words or phrases without leaving the application you're running (e.g. Internet Explorer, Windows Live Mail, Office Mobile, etc.). You can configure the resident module to be launched via keyboard shortcuts or hardware buttons.
Besides just being an excellent reference, Talking VOX makes for a great study aid, too. You can mark words to be added to a list of flash cards, which can then be used to test yourself in the form of a quiz, within the program.
Because of the magnitude of the program, Talking VOX can be a little tricky to find your way around at first. I particularly found it strange that there are two separate context menus, depending on whether you've hit 'Translate' or not. Personally, I felt that these could've been combined into one to make things easier.
That said, Talking VOX English-Spanish and Spanish-English dictionary makes for handy, pocket-sized travel companion and study aid.
