Building a cloud-free digital voice assistant with FOSS (camp2023)

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. about this event: https://pretalx.c3voc.de/camp2023/talk/AUN3FY/
