voice-control-goof

Simple library to goof around with voice control using Google unofficial speech-to-text and text-to-speech APIs.
A somewhat configurable module structure to add functionality!

Quickstart (OSX)

• Install Homebrew

    ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
  

• Install sox, portaudio, flac and pocketsphinx

    brew install sox
    brew install portaudio
    brew install flac
    brew install cmu-pocketsphinx
  

• If it's the first time you install a brew package that includes a python module, be sure to follow the warning that brew showed when installing cmu-pocketsphinx

    If you need Python to find the installed site-packages:
    mkdir -p ~/Library/Python/2.7/lib/python/site-packages
    echo '/usr/local/lib/python2.7/site-packages' > ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth
  

• Install pip and PyAudio

    sudo easy_install pip
    sudo pip install --allow-external PyAudio --allow-unverified PyAudio PyAudio
  

• Clone this

    git clone https://github.com/fopina/voice-control-goof
  

• Copy config.py.example to config.py and download Jasper language model and dictionary

    cd voice-control-goof
    cp config.py.example config.py
    curl -O https://raw.githubusercontent.com/jasperproject/jasper-client/master/client/languagemodel_persona.lm
    curl -O https://raw.githubusercontent.com/jasperproject/jasper-client/master/client/dictionary_persona.dic
  

• Optionally, get your own Google Speech API key and update config.py

• Goof!
