What does it take to build a fully functional (and actually usable) voice assistant that runs on a Raspberry with FOSS? This talk describes the journey from the idea to Version 1.0 (and beyond).
It has to be a HAL9000 - the enclosure for my cloud-free digital voice assistant. The personal project is based on FOSS and runs on a Raspberry Pi Zero2 W in combination with a RP2040 (with a small display showing an animated HAL eye and a small GUI).
I will talk about:
* design decisions (and changes),
* the system architecture,
* why which software components were chosen,
* highlight some interesting hardware and software aspects and
* quickly show how the 3D model for the enclosure was created with OpenSCAD.
HAL will talk about:
* the 9000 series,
* the AE-35 unit,
* ...and whatever else the demo gods will allow.
This talk should also serve as a crash-course into the (basic) technology of digital voice assistants - stuffed with information (and anecdotes) about the hardware, software and the 3D-printed enclosure.
