Speech Recognition-based Podcast Search

PodZinger has recently launched its podcast search engine. The search index is actually created by running podcast audio content through a speech recognizer. What is really powerful is how they display the search results. In addition to getting links to the podcast's rss feed, you get a list of time marks within the podcast marking where the term was used!

So for example, when I search with the term "speech recognition" and sort by relevancy, an NPR program from October 2005 discussing speech recognition technology shows up, with 50+ additional podcasts that recently used the term speech recognition. If I click on one of the time marks, the player (applet embedded in the html page) begins playing within the segment where speech recognition is discussed.

If you listen to podcasts and are interested in finding out who's saying what about specific topics, this is a very handy tool.
