Hi guys, its kinda frustrating but I'm not able to solve this problem on my own. When it works, it works quite well and will run for hours. However, often when I start it up, it does not respond to the microphone at all. The microphone is still working according to the Sound Settings input page, but pocketsphinx just doesn't seem to receive the input. After it has been running properly, I can just stop it with control C and start it again and it may or may not work properly. No changes are made between stopping and starting it.

It seems that the data gets lost...

How is this problem related to ROS?

I'm guessing because of wiki/pocketsphinx :).

Did you observe any difference in a silent environment vs loud/noisy environment on startup?

Can you please attach images to the question itself? I've given you enough karma to do that now.
