title: Speech to Text (Voice Recognition) Directly from Audio / Transcription
body: <p>Need to be able to convert or transcribe audio (eg from .MP3, other audio format) containing speech into text transcripts using a speech to text (voice recognition) algorithm with high accuracy.
  There are many available ways of doing this that are increasingly accurate but are designed for speech spoken into the device microphone (e.g. the Google Translate/corresponding API for web, Dragon app for iOS).
  I need a way to directly feed an audio file into the speech recognition engine/API.
  Don't want to play the audio through a speaker and capture it with a microphone -- takes considerable time for long audio files, and degrades audio quality and resulting transcription quality.
  Does a web service, or API, or code for this exist?  Is there some kind of a wrapper around one of the existing services that presume that the microphone will be the source?</p>
  
  <p>Thanks</p>
