This is a small testing program that uses both CMUSphinx and GTK+ to demonstrate keyword spotting (KWS) algorithm.
In main.c, the program fires up a thread for handling GUI jobs right after it started. Then, it started to setup pocketsphinx and call recognize_from_microphone or recognize_from_file for the audio input. Since argc/argv is passed into the settings, the user can specify the dictionary file or log file as what is written in run.sh.
