Adding voice control to Home a**istant is quite easy now. Typically, you could set up a cloud-based or a local LLM with Home a**istant. Now, you can use the new Speech-to-Phrase feature with Home a**istant running on a low-powered Raspberry Pi 4. While the response time is reasonably fast, it stores all the conversation data locally while you engage in spewing voice commands to control your smart devices.
