Requirements and instructions:

In order to use this, you need the following packages ( marked with an * )

Please follow these install procedures IN ORDER, if not bundled into an .exe (an install script can be made)

*Python 2.7 (comes by dfault with all linux distros. Arch linux uses python 3+ but should still come with a 2.7 version, check your system before installing this)
*python -m pip install pyttsx
*python -m pip install SpeechRecognition
*sudo apt-get install libasound-dev
*PortAudio (Download it here: http://www.portaudio.com/download.html , then follow these instructions: http://portaudio.com/docs/v19-doxydocs/compile_linux.html )
*python -m pip install PyAudio
*sudo apt-get install build-essential libpcre3-dev
*python -m pip install pep8 (can be forced with sudo -H python -m pip install pep8) Run python -m pip list to check if pep8 exists already
*sudo apt-get install automake byacc flex
*swig
    on some systems running sudo apt-get install gcc automake autoconf libtool bison swig python-dev libpulse-dev 
    can get everything that you need. Which means the following steps upto (*PocketSphinx) can be skipped.

    Steps to install swig: git clone https://github.com/swig/swig.git 
                           cd swig 
                           ./autogen.sh && ./configure && make
                      
*python -m pip install PocketSphinx

For windows or mac based systems you'll need a FLAC encoder. You're own your own there.

Notes on Voice input:

The latency between the users voice commands and the program responding is noticeable. It can be fixed in a variety of ways and I'll work on that now...

Sphinx is NOT the best for this. If you speak in a normal speaking voice and try to make it clear it does accuratley interpret what you say.

The key thing in this stage is that the logner you speak the longer it takes her to respond!
