Nice project--I like the code, it's very clean and well structured. You should check out the subversion trunk of pocketsphinx, it has support for keyword spotting built in so you can do things like instantly recognize the persona keyword to enable the system instead of running the transcription through pocketsphinx and hoping for the best. Unfortunately the keyword spotting stuff isn't documented yet, but check out the code for my Demolition Man swear detector project which is using it: http://hackaday.io/project/531-Demolition-Man-Verbal-Morality-Statute-Monitor http://hackaday.io/project/531-Demolition-Man-Verbal-Moralit... The important bit is the ps_set_kws function call, this takes either a text keyword or filename with list of keywords. Then after processing audio call ps_get_hyp and it will return any spotted keywords.
