I find that Voiceover will very frequently stop speaking mid sentence or mid word. This is usually, but not always, on a webpage. It usually happens when moving through elements with VO right and left or just left and right with quick nav. Focus will land on a block of text and Voiceover will read fine for a while and after a seemingly random period of time, it will just stop. It does not require a VO restart to get it talking again. It just stops reading that element. I can move to another block of text or back to the same one and the behavior may or may not repeat. This started when I updated to Big Sur, which is what I am still running. I use Alex as my voice. Have others seen this and does anyone have any idea as to the cause or how to stop it? Does it get better or worse in later versions of Mac OS?
