ROS package for pocketsphinx

Original repository: https://github.com/mikeferguson/pocketsphinx

Also used repo: https://github.com/gorinars/ros_voice_control

You can know more about pocketpshinx here: https://cmusphinx.github.io/

This package is an attempt to bring offline speech recognition to ROS. Pocketsphinx already offers many easy-to-use features in this domain, hence this package can be considered as an extension of pocketsphinx in the ROS world!

Dependencies

  1. pyaudio 
    sudo pip install pyaudio
    If this does not work, follow instructions below: 
    sudo apt-get install libasound-dev
sudo apt-get install python-pyaudio
  2. pocketsphinx: You will need to have pip preinstalled for this to work 
    sudo pip install pocketsphinx
    There are many dependencies which need to be met before installation of pocketsphinx through pip works. Use Synaptics package manager to install the unmet dependencies which would be mentioned as error messages on the terminal window in case installation fails. Some of them include:
    libpulse-dev
    swig
