I just ran across a program called LingoJump. It’s a collection of audios where a native speaker pronounces at normal speed, then really drawn out, then less drawn out, then back at normal speed. I’ve been listening for Turkish and Mandarin. For Turkish, I don’t know yet. But a nice thing about the Mandarin is that you can hear the shifts in the tones. Very useful. As with most programs, this advertises itself as perfect for learners of any level. I’d say it’s most useful for someone with comprehension of basic phrases and some vocabulary, otherwise it’s going to take some serious time to figure out what you’re listening to. But if you’ve got that basic background, this is a nice way to figure out how to put together phrases that you just can’t make come out all at once.
LingoJump comes in a variety of languages. For a language addict, your best bet might be a subscription to Scribd.com, where you can download most of them to your phone as part of the service. (Note to self: You really need to sign up with affiliate programs for some of these things again.)
