I can vouch for Rhasspy, it's an amazing and flexible piece of software, though it does require some setup and tech knowledge (albeit with a usable web GUI); and it's very DIY on defining the actual voice commands. I recommend pairing it with Node-RED [0] for routing commands to devices, it has plugins for most things. The only thing I struggled with was getting the wake-word config right: I could never find the right balance point where it responded every time, without also having annoying false positives, so I ended up turning it off. It does support multiple wake-word engines; I'm gonna have another go with Picovoice Porcupine now that they're opened up custom wake-word training for free. I'm most heavily experienced with Rhasspy's sister project, voice2json [1], which I used to build a voice-controlled car jukebox [2], and it's been working fantastically. (It triggers from a Bluetooth remote, so no wake-word issues.) The two projects share the same core engine. For hardware, Raspberry 3/4 perform quite well, and strong recommend for ReSpeaker [3] for audio (either usb or 4-mic hat).
