Raspberry Pi hotword voice assistant

A voice assistant, along the same vein as Amazon Echo and Google Home using Snowboy hotword detection for the voice activation.

This is really a pet project, so a lot of the commands here are heavily personalised for my use, but there's nothing really stopping anyone from modifying it for theirs.

Features

Weather updates (using Dark Sky and Google TTS)
News Flash briefing from BBC World News
Philips Hue lights
Wake-on-lan

Dependancies:

snowboy kitt.ai (Included as snowboy-linux or snowboy-pi, for Ubuntu and Raspberry Pi respectively)
sudo apt-get install mpg321 wakeonlan libatlas3-base python-mutagen libboost-all-dev
pip install qhue gTTS schedul pygame face_recognition

Setup

Sign up for a Dark Sky dev account
Update config.py with the following

[snowboy]
raspberry_pi: False  # Set to True if running on a Raspberry Pi

[hue]
user: your_hue_user_id
bridge_ip: your_hue_bridge_ip_address

[weather]
api_key: your_dark_sky_api_token
  location_lon: your_longitude
  location_lat: your_latitude
  units: uk2

Running everything

From terminal, run python hotword.py

Commands

Saying Okay SAM will activate the assistant and open up a set of secondary commands (a bit like saying "Okay Google"):

Weather
- Any sentence with the word weather
- "What's the weather like?"
- "Give me the weather"
News headlines
- Any sentence with news or headlines
- "Play the news"
- "What are today's headlines?"

Some commands can be said without needing to say Okay SAM:

Lights
- "Turn the lights on"
- "Turn the lights off"
- "Dim the lights"
- "Full brightness"
- "Everything off"
Wake on LAN
- "Computer"
Stop command
- "Cancel that"
- "Stop playing"

You might find better results to record your own activation words on the Snowboy Hotword Detection website. Hotword files (.pdml) can be placed in the hotword_models folder in the corresponding category folder. For example, to add your own "Okay SAM" hotword:
