Discovery is IMO the biggest reason why voice interfaces will never take off. Mapping the space of possible solutions is delegated to your brain. You are responsible for remembering what's possible, what you can do, and what you should say to make that happen. The majority of the time you will fail, because you forgot what the magic spell actually was. Visual interface has an unobtrusive way of showing you what you can do. More importantly - it can show you multliple options at once. Voice feedback can only tell you one thing at a time and very slowly. Voice assistants are called that for a reason - core assumption is that you share your intent, and assistant is smart enough to make that happen. But that does not work with people either! Nobody can read your mind (yet) - that is why project requirements and management exists. I would love to tell my team one sentence of what I want done, but I have to review that at some point. I am not using voice assistant to do human things badly. I want it to do computer things well.
