I've been working on a voice assistant. I would love to understand if there are any books or articles you can suggest to learn more about voice UX. I've learned a bit about voice activity detection or interruption handling, I would love to learn more about how we can provide best experience.
Developer conference talks can be a good source as an alternative, they tend to get into the nitty gritty, talk about the hard parts, and overcoming difficulties in production settings
I recall a talk from a Google i/o a few years back where they talked about how voice only is not the way, that depending on the question & answer, you want to move the user across modals
