Voice assistants like Amazon Alexa or Google Assistant allow to control numerous functionalities in the smart home via spoken language. For many people, however, such a cloud-based solution is out of the question due to considerable concerns about security, data protection and privacy, although they would like to use the functionality of voice control.
The implementation of a local «offline» voice assistant (which does not require any internet access) with open source tools is a solution to eliminate these security concerns and to exploit the potential of this interested customer group.
This workshop will show what is currently possible with open source tools. By the end of the workshop the participants should know how to build a local voice assistant.
Tutorial Outline (half-day event)
- Welcome / Introduction

Target Audience & Requirements
We target a broad audience interested in the implementation of a local voice assistant. We will provide sample code in python, so for the hands-on part, it would be good to have some experience installing python packages and intermediate Python skills.
Note: Participants must bring a laptop.
