kalliope

I hooked up Kalliope[1] to Home Assistant to do exactly this, except for the ad skipping voice command. [1] https://github.com/kalliope-project/kalliope

Kalliope[1] is a no code, but Python-based, voice assistant. I like it because you can switch out voice backends and it is designed to be modular with node-like constructs to build signals and responses. I stuck it in a container and can control Home Assistant with it, run scripts, etc. [1] https://github.com/kalliope-project/kalliope

Kalliope, another open-source voice assistant (https://github.com/kalliope-project/kalliope) also has the option to use an offline wake-word backend like snowboy.

There are a fair few people trying to create this. The one I've come across that looks the most promising is https://github.com/kalliope-project/kalliope/ . I've not tested it but have had it in my starred projects for a while now.

Kalliope is a modular always-on voice controlled personal assistant designed for home automation. This new release brings new features, fixes many bugs and new plugins (called neurons !). You can check details, videos and the neuron market place on the github page : https://kalliope-project.github.io/ The target is a rasp3 on raspbian, but you can quickly test it on a Ubuntu. You just need a microphone and a speaker/heapphones. The project is open source under the MIT licence. Find sources on github : https://github.com/kalliope-project/kalliope Enjoy !

I stumbled upon kalliope recently (https://github.com/kalliope-project/kalliope). I tried it a few weeks ago and was pleased with it in general but it still needed an online connection in order to parse your commands. According to the changelog they added the option for an offline STT recognition now.
