I don't think the device would have enough power to do this internally, but I think you might be able to use the audiocapture API to capture the audio, send it to a server to process, and get some result back.
I used the below code to test this and it worked using FTP. I was not able to get the code as shown on the docs to work. It seems like there may be a parsing issue with colons.
audioCapture.duration = '10000';
audioCapture.audioSaveEvent = 'showresult(%json)';
audioCapture.username = 'dan';
audioCapture.password = 'test';
audioCapture.source = "\\RE_AudioCapture.wav";
audioCapture.destination = "url('ftp://192.168.128.103/cap.wav')"
