Good day to all once again.
Just want to share this as I have also ask help in some forums. And these all wrapped up to my conclusion.
Using online speech to text services we can convert audio files to text document easily and its more reliable than downloaded software.
Dragon is the most commonly used but can’t be taken for professional purposes since you still have to train it.
I’ve tried to hire in elance, freelance, odesk, but is way much too expensive and could not afford it.
So, I settled with the service like http://www.speechtotextservice.com/ and did worked well.
But one thing is for sure. As of the present technology in transcription, still nothing is free, unless you still do the work.
Anyway, much appreciated all your help. Thanks a lot also for this forum.
