Milobella device Client

Run milobella in a device, using mic and speakers to communicate.

Requirements

Check requirements before install

#1 : Google cloud authentication configuration

Authentication process is detailed in this documentation https://cloud.google.com/speech-to-text/docs/quickstart-protocol.

It is using basically a GOOGLE_APPLICATION_CREDENTIALS env variable pointing to a JSON private key file. The JSON private key is generated when you create a Service Account.

Make sure you activated both of the APIs in your Google Cloud Project, and the same JSON file will be used.

#2 : Milobella authentication configuration

The env variable MILOBELLA_AUTHORIZATION_TOKEN should contain the JWToken generated every time you authenticate. A script authenticate.sh is here to show you how. (You need jq if you want to use it)

export MILOBELLA_USERNAME=myuser
export MILOBELLA_PASSWORD=mypass
source authenticate.sh

#3 : Raspberry audio configuration

If you are using a Raspberry PI B+ with RASPIAUDIO Ultra +, check the RASPIAUDIO ultra+ configuation documentation.

#4 : Make sure you have all dependencies installed

On linux :

sudo apt-get install libasound-dev portaudio19-dev libportaudio2 libportaudiocpp0
sudo apt-get install ffmpeg
sudo apt-get install libpulse-dev
sudo apt-get install python3-pyaudio
