Voice control continuous dictation drops out when switching application windows (Monterey, M1, 8GB)

Voice control on Monterey (with M1 hardware) is now excellent, and I'm using it all the time for the past few days, along with the head pointer. It's now so good that I'm becoming frustrated that it's not perfect... I'm using ulysses alongside chrome, switching to Ulysses to take notes (by dictation). Sometimes voice control will enter a state where it will respond to commands (such as "press a key" (producing a letter 'a') but will not take continuous dictation. It's could well be a bug, but I'm trying to track it down, or at least isolate cause and effect. No luck yet.. More info: - switching voice control off and on again restores continuous dictation. Before I did that, it was responding only to commands, not continuous dictation. - the microphone level indicator at the bottom right hand of the screen now does not update, perhaps suggesting a high tax on system resources from running voice control; or a lack of optimisation given it is still an early feature. - I'm using an M1 mini with 8 GB of RAM & a usb snowball blue mic. - unlike some enthusiastic reviewers suggested, these machines are not omnipotent. Activity monitor shows memory pressure yellow, and one red spike about when I switch to voice control on and off. I have no other significant applications are running other than chrome with quite a few tabs. - I'm curious whether an M1 with larger memory may not have this issue, but don't have one to test as yet. - I've now found one reliable partial work around/ isolation of the bug. If I have two microphones plugged in, and when it drops out, switch to the other microphone in voice control preferences, continuous dictation returns. This is of course very unergonomic, but it's better than nothing. *Can anyone who has an M1 with 16G+ RAM please check if continuous dictation works reliably without dropping out when switching between applications? I suspect this might help but do not have such a machine to hand at present.*
