Slow Chinese is a great learning resource. A blog provided by a native Chinese (Xinyu Weng). Currently there are 36 articles all with audio.
The Chinese is spoken slowly and clearly (some people have said too slowly but hey read the title, it does what it says on the tin) and the language used is accessible (it has been pointed out maybe slightly too accessible in places, but I think that is appropiate to the aim of the site).
I am using the site mainly at the moment to improve my reading, it is great to have the option to listen to audio, particularly as my approach to learning Chinese means that at the moment I can understand considerably more than I can sight read (being addressed right now though), still learning a bunch of new words from it also.
You can find the podcast in Itunes and text is included in the description (so you can read whilst listening). If you prefer the audio a little faster then my Ipod touch does a reasonable job playing at 2x speed (the pitch is held constant it is just the speed that is increased). If need you could probably do a reasonable job of increasing the speed using a tool like audacity.
Ok not entirely natural but that is the point, there are plenty of natural sources of native Chinese, Slow Chinese however can be a great help for learners looking for either listening or reading (with audio) practice or both.
If anybody knows of any similar resources with the same aim then let me know.
If you use this resoure, and like it then consider leaving a donation to the author, it will encourage more of the same I hope and perhaps some variations.
