python-alexa-client

Experimental Python implementation of an Alexa Voice Service client.

I use this as one component of a home-grown Raspberry Pi radio, which has the following features:

• Flic support
• PiGlow support
• Podcast playing
• Streaming music playing
• Alexa Voice Service integration
• Text to speech from IVONA

The Alexa Voice Service component is provided by the python libraries in this repository.

It's certainly not ready for anyone else to just pick up and use, but I wanted to get it out there as I didn't find any other implementations.

Development status

Very very early - mostly this is experiments to try to understand the documentation.

Features

• Streaming voice to AVS
• Supports most AVS features, including alarms, alerts, listen directives and so on

Use

See the bottom of alexa.py - you can try running alexa.py for a simple demo, which uses a local text-to-speech system rather than your microphone to generate voice requests.

You'll need a tokens.json, which you can probably get with the help of get-aws-token.py - edit and fill in the FILLMEIN parts. (Or better, make it ask for those elements and send in a pull request!)

You'll need to configure the redirect_uri in your app in the AVS dev site to http://localhost:3000/authresponse.
