sudo apt-get upgrade
cat /proc/asound/cards

check your microphone is visible or not and if on which usb extension

sudo nano /etc/modprobe.d/alsa-base.conf
Now change this
Keep snd-usb-audio from being loaded as first soundsudcard
To options snd-usb-audio index=0

if there is some other options snd-usb-audio index=1, comment it out

sudo reboot
cat /proc/asound/cards

check your device is at 0

sudo apt-get install bison
sudo apt-get install libasound2-dev

make
sudo make install

download pocketsphinx, extract

./configure
make
sudo make install
export LD_LIBRARY_PATH=/usr/local/lib
