Recorded Speech to Text Software?

shfted! asks: "Recently, I've been given the task of transcribing several dozen audio tapes of interviews to typed word, that is, listening for 10 seconds, write what was said, repeat. At around 4 hours per hour long tape, I would like to automate the process somehow. Recording the tape into the computer is no problem, but I need some software that will do the speech recognition accurately more than quickly -- several hours per tape is not an issue (I have access to several machines running 24/7). I will still have to go over the computer's work to correct any mistakes. A free solution for Linux would be best, non-free and Windows solutions are okay, but a working solution is highest priority. Can anyone point me in the right direction(s)?"

Slow the playback down

Slow the playback down and type them as you listen. If you can't do this, hire someone who can. I know many people that can keep up with spoken conversations in real-time.

Years ago, I improved my own typing speed and accuracy by transcribing phone conversations with friends. It just takes some practice.

Of course, if you are listening to this guy, you can disregard my advice.

Sphinx

Give Sphinx a try. It's pretty accurate; especially Sphinx-3. I've used v2 before for a live test, and it works great -- even with different voices.
