Pronouncing words with real life examples

If you are teaching English you may be interested in this interesting mashup put together by embedplus, of a kind of dictionary and YouTube put together:

Search for a word, and you  will get pronunciation, but also YouTube video exemplars of real usage of the word.  What's really clever is that the video will jump to the bit of the video with the word being used.  It's not always just what you want, (I get an icehockey clip for the word "offside" rather than UK football) and sometimes you have to wait a little bit for the videos to appear, but excellent for students wanting to see and hear real life usage of vocabulary.
