title: What is the current best speech recognition API for ios to match few keywords?
body: <p>I am looking for an API for ios (free ideally) that will allow to do some speech recognition. I have seen few posts for this: <a href="https://stackoverflow.com/questions/1121548/iphone-speech-recognition-api">iPhone speech recognition API?</a> and <a href="https://stackoverflow.com/questions/7596816/free-speech-recognition-engines-for-ios"> free speech recognition engines for iOS?</a> and after a bit of prospect i have gathered the sdk that looks quite interesting:</p>

  <li><a href="http://www.creaceed.com/ceedvocalsdk/" rel="nofollow noreferrer">http://www.creaceed.com/ceedvocalsdk/</a> (not free :-\ )</li>
  <li><a href="http://www.ispeech.org/" rel="nofollow noreferrer">http://www.ispeech.org/</a></li>
  </ul>
  
  <p>is there any of those that really stand out of the crowd and quite recent? how do they really differentiate from each other?</p>
