Speech recognition (web) services?

开发者_开发百科

I have a buffer of audio and I'd like to perform speech recognition/transcription on it. I have limited CPU and RAM locally so I want to perform recognition on a server.

Are there any (web) services that allow me to do this?

My searches so far have led nowhere...

Google has just introduced browser-based access to its speech engine through HTML5.

To get this page to work, I launched the Chromium browser as follows in Ubuntu:

$ chromium-browser --enable-speech-input

I believe that the idea is to be able to build applications that use Google's speech recognizer, but I haven't had a chance to look deeply into it.

Another interesting project is WAMI from MIT: http://wami.csail.mit.edu

Lumenvox offers such a service but seems expensive for your needs.
