I would like to implement a project in which the recorded audio s converted into text. I could do this using mturk where the recorded audio is uploaded and stored some where in cloud and the link is forwarded to the mturk 开发者_如何学JAVAbut this would take longer time and it would be better if I could implement anything that does this task instantly and from iphone itself. Is there any ways to do this ? DO i get some custom framework to work with voice so that it converts the audio into text.

Your best bet is looking at something like OpenEars

You can use that to do speech recognition and text to speech and has some instructions on how to implement with iPhone
