From the Podscope FAQ:What is Podscope?
Podscope is the first search engine that actually allows you to search for spoken words within any audio or video file. We’re starting with podcasts and will be adding all types of multimedia in coming months.
How does it work?
Just like any other search engine. You enter a word or phrase in the input box, and we’ll show you a list of results. By clicking on the (+) sign next to each result, you can select snippets of audio to help you decide whether to listen to the whole podcast or even subscribe. If you know about Search Inside the Book, that’s what we do for audio/video.
