Sphinx4 Speech Recognition from a video

Does 开发者_如何转开发Sphinx4 support Speech-to-Text processing on video files? If yes, Does it need JMF? Is there any tutorials ??

I couldn't find anything, not in their forum, and nobody is responding in their IRC Channel!

Does Sphinx4 support Speech-to-Text processing on video files?

Yes. There is no specifics of the video. You need to extract the audio track and pass it to recognizer.

If yes, Does it need JMF?

There could be different way to extract audio track from the video. It can be JMF or just mplayer

Is there any tutorials ??
