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.

Thanks

I don't think there is any viable open source voice recognition program. First, the technology itself is not yet good enough for general speakers. Second, if a voice recognition program has acceptable accuracy, it has huge profitability.

The most accessible and usable voice recognition I know is that of Google Voice. Google implemented exactly what you described for voice mail of Google Voice.

I realized that I wrongly used the term "voice recognition" following the author.
Just to clarify; voice recognition is to identify the speaker. Speech to text conversion is called speech recognition.
