Every major player in the industry – Amazon, Apple, Google, and I think Microsoft – has a voice assistant which requires no button to start or stop interacting with the assistant. It seems clunky to have to press a button to start speaking, and again to stop speaking. And natural language processing seems well short of best-in-class, too. I had to figure out the word “navigate” to get what I wanted; questions like “how do I get to X” didn’t seem to work.
