I know php well and I use javascript and jquery but I don't seem to know how to make a speech to text conversion with them though, but i do know that there are many flash speech recognition api's around but I would like a faster, I would like a script for this that can accurately use your voice and convert it into text. Thank you very Much, Anonymous.

  • I'd assume that one is impossible. I don't know any library to analyse sounds for PHP. – TimWolla Jan 01 '12 at 14:53

    I wouldn't go so far as to say its impossible, just that any sane developer wouldn't choose PHP or JavaScript as candidates for doing speech recognition – jprofitt Jan 01 '12 at 14:55
  • A JS speech recognition program may well be impossible. – benesch Jan 01 '12 at 15:52

If your goal is to do speech recognition from an html page, you might want to look at some other alternatives. Chrome supports speech recognition for text input. See http://slides.html5rocks.com/#speech-input and http://www.filosophy.org/2011/03/talking-to-the-web-the-basics-of-html5-speech-input/.

These use the following tag for speech recognition:

<input type=”text” speech x-webkit-speech />

I believe Chrome is the only browser that currently supports this. http://tomlerendu.com/tutorial/how-to-use-html-5-speech-input/ has a good example and shows 

if( document.createElement('input').webkitSpeech==undefined )
{
  //no speech support
}

as a means to test if speech recognition is supported.

Historically, there have been other approaches. Opera implemented a different solution, but it appears they are no longer supporting it - http://dev.opera.com/articles/view/getting-to-know-voice/.

Another approach that has been used is to use a java applet or flash app that communicates with a speech recognition back end. WAMI is a good example of this - http://wami.csail.mit.edu/. These approaches use a rich client (Java or Flash or other plug in) to capture speech and send it to a server or some local speech engine for processing.

  • Voice recognition is possible, *pokes SIRI*, and has been going on for quite awhile. (I believe over ten years ago) the thing is it can never be *PERFECT*, do to user errors. Also the old ones were not written in PHP, mainly C or C++ or maybe Java. – JD3 Dec 04 '13 at 13:11

You could have a look at speechapi.com and build yourself what you need but if its the other way around;text to speech,speak.js will do.

Hope that helps.
