When I create my course podcasts, I write a script, read it over once or twice, and then record it. As I wrote in one of yesterday's entries, I recorded a podcast for next week's class using audio over a Powerpoint presentation. Then, in Camtasia Studio 4, I exported it to iPod/iTunes which created both .m4v and .mp3 files. I added the .m4v to my class podcast series.
However, this left me without a script to put up on my podcasts text page. I always put the text up on the course website to comply with ADA guidelines. What to do?
I took the .mp3 file, opened it in Audacity, exported it to a WAV file, and then opened the WAV file in Dragon's Naturally Speaking. Naturally Speaking will "read" a WAV file and convert it to text in a RTF document. I then took that document and edited it, playing the audio in short bursts. It's said Naturally Speaking is about 80% correct after you train it to your voice. I guess that's about right. It still requires a lot of tedious, time-consuming editing to get the text to a useful point. All told, I spent about 2 hours working on it today.
