Voice Assistant hardware requirements for the *server* end

Configuration Voice Assistant
1

I did some interesting tests earlier today. I’m running Home Assistant on a VM under Proxmox. It initially had two CPUs.

I ran a voice automation with a fairly complex and long response, and that took about 12 seconds before I started hearing anything. I did it again and watched the CPU usage on the HA VM. For about eight seconds, it was at 95-100%.

So then I gave the VM two more CPUs (for a total of four) and ran the same automation. This time it took only about six seconds.

I’m looking to buy dedicated hardware to run HA on, so that I don’t have all the moving parts of Proxmox for part of my critical infrastructure. I was thinking about getting a Beelink mini PC or similar, but now I’m wondering if I should go with something more powerful. The cost (within reason) isn’t really as important to me as fast voice response - especially with an eye toward adding local AI to the mix later (although I could run that on other dedicated hardware if needed). Thoughts anyone?

Before messing too much with hardware try to use VOSK for stt, its not as accurate but it is much faster. Works for me and made voice assistant useable.

I run proxmox on an HP T630, so not powerful hardware.

I hadn’t seen that before. I’ll check it out. Thanks for the pointer!

Where do I find the file to edit for adding all my custom sentences in Vosk?

In the add-on documentation, it says /share/vosk/sentences/en.yaml, but the vosk folder on down doesn’t exist. I guess I have to create that myself? Seems unusual, I feel like addons usually create at least the folder structure they require.
