I think it’s silly to speak in full sentences to home assistants, when I really just use 5 commands most of the time.
It would be snappier to make weird sounds, produced by snapping ones tongue e.g., like some African tribes use in their languages.
Or any other weird, short sounds.
It might be more satisfying to use, and probably funnier.
Also, over the course of a few years this might find its way into everyday spoken language. Which would be wonderfully dystopian and maybe funny.
A glottal stop is when your glottis stops airflow, not clicks. The airflow pause in “uh-oh” is an example.
Anyway, have you tried using fewer words for those commands? Even if you got a tongue click setup for a timer, you’d still need to say how long
