Hi, I'm trying to find or write an application which will run through an audio file (in wav) file then go through the file, coming up with a text version of the audio. It's a phone call audio file which I'm trying to auto-transcribe hopefully as accurate as possible. I know the origin and the destination so I can log the call and allocate the call details correctly.
Can someone who has experience with this advise on which app (open source or proprietary) which I can integrate with a Ruby on Rails application on a Linux platform? I guess the processing of the audio file can be done via a cron job or something.
