I'm currently trying to teach my Dad with Alzheimers how to use Facebook portal TV so we can stay in touch. He's struggles to use it because he says 'Hi PortAL' and can't get the words 'phone [my name]' out fast enough. He feels like such a failure when it doesn't work. Is it possible to get Portal to recognise Hi instead of just Hey and port-AL rather than just portal. Also it would be great if it can listen out for commands a tiny bit longer, while my Dad finds his words.
