If you have used podcasts and online audio much, you might have developed a slight frustration that you cannot browse them to find relevant sections, like you can with blogs and indeed any textual information. In my experience this means that listening to podcasts is not a very efficient way to 'graze' your way through relevant information, and personally I just listen to them while performing other tasks that I can do subconciously.
Well the solution to that issue is here thanks to http://podzinger.com/. This increadibly well thought out site, uses voice recognition technology to turn the audio into a searchable text file. So if you search for "Learning Technology", for example, you will get links to the registered podcasts that mention this phrase.
But not only that!
You will be able to see the context in which the phrase was used and you even get a link to that section of the podcast. If you use a podcast reciever you can subscribe to download any future podcasts that use the phrase, which might be an efficient way of searching for relevant information on very obscure topics that are mentioned little and aren't worth searching for regularly.
In my mind, this technology makes podcasts as useful as blogs for information 'grazing' and discovery.
