Language Learning Center is a tool to help you learn new languages using an audio-visual approach. The theory is to learn the basics, then expand on them. Language Learning Center is designed for Mac OS X and installs quickly.
The Language Learning Center interface looks like a chalkboard. From there you can go to learn basic nouns by looking at images and getting the translations for those objects. The interface lets you hear the correct pronunciation and see the written version. By using native speakers, the program lets you hear the correct pronunciations, and almost all words or phrases are presented by both male and female speakers to help with intonations. By building word on word, developing phrases, you learn the language more easily. The basic app is free, and language packs for a number of languages are $3.99 each.
Although the approach used by Language Learning Center is not unique (a famous learning system uses a similar approach) the very low cost of Language Learning Center makes this an attractive package. Although it won't get you through to fluency, as there's not enough depth to the languages available, it will get you to conversational levels.
