Alias is a teachable “parasite” that gives you more control over your smart assistant’s customization and privacy. Through a simple app, you can train Alias to react to a self-chosen wake-word; once trained, Alias takes control over your home assistant by activating it for you. When you’re not using it, Alias makes sure the assistant is paralyzed and unable to listen to your conversations.
When placed on top of your home assistant, Alias uses two small speakers to interrupt the assistant’s listening with a constant low noise that feeds directly into the microphone of the assistant. When Alias recognizes your user-created wake-word (e.g., “Hey Alias” or “Jarvis” or whatever), it stops the noise and quietly activates the assistant by speaking the original wake-word (e.g., “Alexa” or “Hey Google”).
From here the assistant can be used as normal. Your wake-word is detected by a small neural network program that runs locally on Alias, so the sounds of your home are not uploaded to anyone’s cloud.
