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)?"

Lo tek is the way to go in this instance

Several hours per tape is acceptable? Well, if you can do one tape in four hours, then two people can do one tape in two hours. In other words, hire a college student at minimum wage for a contract position (I.e. until the tapes are transcribed) and go to it.

It's cost effective, as fast as you need it to be and best of all more accurate than any software solution to date. Most software packages are still at only about 90% accuracy, so that's still 24 minutes per four hour tape that you'll need to correct, and you'll still probably have to listen to the whole thing over again in order to verify the accuracy of any software program.
