Is there any way, by which we can convert speech to Text using iPhone SDK?

Yes, if you are Google, Dragon, or Siri. The iPhone SDK does not provide any access to the iPhone 3GS's built-in voice recognition, which is apparently none too elaborate anyway. Your best bet is to find a web service to which you can upload audio clips for analysis.

1Yes. The article I linked to ("none too elaborate") explains how the speech synthesis API works; it's a little more robust, but is still not part of the public SDK. As such, using it, rather than a web-based text-to-speech service, will get your app rejected for use of a private API. – Noah Witherspoon Feb 17 '10 at 13:15

As of iOS 10 (not released yet), Apple has their own speech recognition API.
