It should be really something like Beneficial Audio Realtime Recognition Electronic Transformer.

Earlier quoted context omitted.

Pi-C.A.R.D is perfect. Read it 100% as Picard, and more recognizable that LCARS.

Just configure it to respond to "Computer" and you're good to go.

The wake word detection is an interesting problem here. As you can see in the repo, I have a lot of mis-heard versions of the wake word in place, in this case being "Raspberry". Since the system heats up fast you need a fan, and with the microphone directly on a USB port next to the fan, I needed something distinct, and computer wasn't cutting it for this.

Changing the transcription model to something a bit better or moving the mic away from the fan could help this happen.

What latency do you get? I'd be interested in seeing a demo video.

Fully depends on the model, how much conversational context you provide, but if you keep things to a bare minimum, ~https://moondream.ai/, but that takes around 45 seconds so the next idea is to take a more basic image captioning model and insert it's output into context and try to cut that time down even more.

I also tried using Vulkan, which is supposedly faster, but the times were a bit slower than normal CPU for Llama CPP.

All I need is a voice assistant that: - RPi 4 can handle, - I can integrate with HomeAssistant, - is offline only, and doesn't send my data anywhere.

This project seems to be ticking most, if not all of the boxes, compared to anything else I've seen. Good job!

While at it, can someone drop a recommendation for a Rpi-compatible mic for Alexa-like usecase?

"Number One" would be my code word...

Or LLM Offline Camera, User Trained Understanding Speech LOCUTUS
