For Watson Speech to Text - Did you choose the correct model to match your source audio quality? They default to a "Broadband" model intended for high quality audio sources, but you can also select "Narrowband" for things like phone quality. Not guaranteeing a difference, but in my experience, matching the source quality to the correct model makes some difference. I've not compared them extensively but for streaming realtime, I found that Watson beat the Google api for a specific use-case. Your mileage may vary! They also provide a handy Mic / File reader interface for browsers: https://github.com/watson-developer-cloud/speech-javascript-...

I'm responsible for the Watson Speech JS SDK, which is aimed at making the speech services easy to use in web apps. Code is at https://github.com/watson-developer-cloud/speech-javascript-... Simple demos at http://watson-speech.mybluemix.net/ More complex demo at https://speech-to-text-demo.mybluemix.net/ I'm goin to be out some this evening but feel free to ask me questions and I'll answer them as available.

Nice! Shameless plug: I'm working on a SDK to make the Watson speech services easier to use in web browsers. It's still got a few rough edges, but it's usable right now, and I'd love to hear feedback from other devs: https://github.com/watson-developer-cloud/speech-javascript-... Update: here's a quick mashup I built with that SDK and the existing demo of the Watson Dialog service a little while back: https://speech-dialog.mybluemix.net/ (warning: audio auto-plays) (I work at IBM, at least for the moment...)
