Fixing Home Assistant Voice Latency and Speech Quality with a Custom Wyoming Docker Stack

When people talk about smart home automation and privacy, two points come up again and again. First, most commercial smart home products are not private. If you want a smart home without handing over your data, Home Assistant is the usual recommendation. Second, the voice experience in Home Assistant Assist often feels slow or robotic.

We have used that solution in the past and it works great as long as you have internet. Outages still happen, though, and that is when the cloud stops being useful. If you want everything to stay local, run the voice stack on a separate machine that is more powerful than a Raspberry Pi. A mini PC gives you extra CPU cores, more RAM, and enough headroom for newer models that a Pi struggles with. That extra…
