Question: Is there a virtual assistant that lets me control my home devices with just my voice?

If you want a virtual assistant that lets you control your home devices with voice commands, Nabu Casa is worth a look. It supports remote access and voice assistants through Assist, Google Assistant and Amazon Alexa, so you can control your Home Assistant instances from Android, Wear OS, iPhone and Apple Watch devices. Nabu Casa has more than 70 neural voices and a private, data-protecting setup process, making it a good option for remote smart home control.

Another contender is QuickSet, which offers an Interoperability-as-a-Service to control and manage entertainment and smart home devices from multiple companies. It includes device discovery, control and interaction through a single remote control, voice assistant or mobile app. QuickSet spans a broad range of devices, including TVs and set-top boxes, so it's a good option for all-around home automation.

If you're already in the Amazon camp, Alexa is a mature virtual assistant that lets you control a lot of devices and services with your voice. Alexa works on iOS and Android devices, and the Alexa App is free to download. That means you can use it to control your daily life and home devices with minimal effort.

Last, DATA offers an AI platform that marries large language models like GPT-4 for personalized and proactive interactions. It's not specifically voice focused, but it can be automated with iOS Shortcuts and controlled with voice or text input. That makes it a good option for home automation and other tasks.
