Hello,
I would like to implement a speech detection which will send sentences to the google API and get the text. This will be permanently listening and doesn't need any vocabulary. so before starting I thought it would be better to ask maybe somebody already did something like that.
A similar thing has been done here https://github.com/Barista-Bot/voice-... in python.
This wasn't on a Nao but our own proprietary robot.
Hope it may be of use.
For a simpler library, you may want to check gspeet: it's a small python library that listen (continously or not) on the microphone (using ALSA. It should work on Nao), encode the speech using the speex encoder (well, a google variant of it, actually -- it still requires libspeex), send it to Google speech API, and returns the result.
Integration in a ROS node should be trivial, but the library itself is independant.

I'm looking for something like you, have you tried the package audio_common? http://wiki.ros.org/audio_common It should catch the sound from the microphones and publish an /audio message. Let us know if it works.
