cloud - Speech Recognition API

Question

I need to automatically transcribe some short MP3s as part of a proof of concept I am working on. I am currently looking into cloud solutions or web API services to send the MP3 as a simple HTTP request and receive a transcription back.

The only free/open source solution I have found here, but the demos don't seem to work (at least not on the files I need to transcribe). I have found some enterprise solutions for call centers, but so far nothing I can simply integrate into a project.

Are there any web based speech recognition services available? One that is able to filter out small noise would be a plus.

Here is an unofficial method to access Google ASR capability. I just tested on Yesterday and it still works - you can get JSON style ASR output with words and associated confidence score from an FLC audio sampled in 16KHz.
