GoogleSpeechRPi

Use Google Cloud Speech to control Raspberry Pi

Objective:

Control the GPIO Pins of a Raspberry Pi on the fly using Google Cloud Speech. I've chosen the most visible implementation of GPIO Pin control, a Light Emitting Diode.

Install libraries:

pip3:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

Versioned version of Google Cloud SDK:

export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)"
echo "deb https://packages.cloud.google.com/apt $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo apt-get update && sudo apt-get install google-cloud-sdk

cloud-speech:

pip3 install --upgrade google-cloud-speech

WiringPi-Python:

sudo apt-get install python3-dev python3-setuptools swig3.0 git

git clone --recursive https://github.com/WiringPi/WiringPi-Python.git
cd WiringPi-Python
git submodule update --init

cd WiringPi
sudo ./build

cd ..
swig3.0 -python wiringpi.i
sudo python3 setup.py install

Setup Google Cloud authentication

sudo su
gcloud auth application-default login

Download and run App

git clone https://github.com/thomas-vl/GoogleSpeechRPi.git
cd GoogleSpeechRPi
sudo python3 main.py

Notes

One of the biggest problems i had was that the audio stream from pyAudio could not be read by the Cloud-Speech client. I feel that Java might be better suited for this. I know that most of the code is ugly please post anything you might feel I could improve.

A big thanks to Jeyson Molina for providing a lot of code to calculate silence tresholds
