The VocabuLearn series covers multiple languages and is purely focused on increasing vocabulary. As such, it's a good complement to other materials which focus on ear-training, speaking, grammar and the like. More material is available on cassette than on CD. Sets include a booklet with terms printed. The format is single-rep: a word is spoken once, than translated, and it then moves on to the next term. There's enough time to repeat. Sequence varies between source/target and target/source. Because there's no real sequencing or building of skills on previous terms, it's a good asset when attention may be fractured, such as when doing housework or working online... I catch the occasional term, and it seems like it would take many repetitions of the entire tape before the majority of material is retained. I had picked up a copy of Japanese 2 at Kinokuniya, and will probably invest in multiple sets from their online store. Hindi is, as usual, under-represented.
