I down-loaded Express Scribe from NCH (u need speech recognition already set up -USE ID 0) -options, speech-to-text. I used a sync folder (read the help from the program) the program will down-load whatever additional software it needs (e.g.. ffmp3 if you are using MP3 format). I used conversion software and output to the sync folder (the program automatically detects (or click the synch button) then will convert the speech (speech-to-text in notes section) I let it run overnight (7 hours) it completed all 10 (each 1 hour long) class lectures. The text is not perfect but it is easier to change or delete the parts I don't need for lecture notes.
