Podzinger uses audio-to-text technology to create text-searchable podcasts. This free service from BBN has now indexed 8 Polizeros podcasts.
Here’s the Polizeros page. At the top is the search box. Type in ‘Hurricane Katrina’, Podzinger will present a list of Polizeros podcasts with those words – and the actual text taken from the podcast. Click on the words as they appear in the text to start listening at that point. Impressive.
