Yes. My husband and I have learned Mandarin (and continue to learn Mandarin) and have now been working on Spanish. Rosetta Stone is widely advertised but it is expensive and actually the reviews aren't that good. We have used podcasts, Pimsleur tapes and I'm now using All Talk. I think the Pimsleur has been the best for me but it can be boring, so I'd intersperse it with some podcasts. We've actually found that there are a lot better materials for Chinese than Spanish. I don't know about French--my husband speaks that pretty well already because his mom was French. I have writte a hub about our learning Mandarin, which gives more information about our experiences. You should start by looking at podcasts--many of these are free. You sometimes spend a small fee to download transcripts. If you buy a one month fee you can usually download as much as you want. Oh--you also may want to look at your library. We just got a great computer program that is free for us to use from ours. It is a Powerspeak program, which I think uses the name Power Glide. My kids are taking Chinese with this in an online school. It is great.
