The world of podcast search is exploding! There are a number of search engines which seek to give order to finding podcasts, much the way that services like
Technorati have made it possible to locate blog postings. These engines allow users to search podcasts by keyword. For example,
Podzinger and
blinkx search audio content for keywords by translating the audio into text and creating an index for quick searching. This is really powerful technology. Usually, an audio search engine would just be searching the title and a short descriptive summary of a broadcast.
Another innovation can be found at
Podscope. This search engines allows users to set up keyword-based RSS feeds and receive alerts when certain words are spoken in a podcast or other types of audio or video programs.
Stay tuned... I strongly suspect there will be much more to report as this medium continues to grow.
