Pluggd: A Google for Podcasts
Using speech-to-text software and studying the contextual relationships between words, a new startup makes audio files as searchable as text on the web.
Pluggd has found a way to index podcasts, talk shows and other spoken-word content. The company's service then allows users to search the audio files for specific words.
You can try Pluggd's word-searching demo yourself right now. Enter your search term and you'll see mentions of your word highlighted in various colors -- heatmap-style -- on a timeline of the show. The redder "hot spot" areas represent denser clusters of your search term, and clicking on one will cause the player to jump straight to the discussion about your desired topic.
