When the R1 misheard you and you try correct it with another query it needs to communicate it couldn’t complete the previous task so it says ‘sorry i’m not able to complete the task’ but this is confusing since you just gave it a new query and it immediately responds with the reply of the other task that is aborted.
Wouldn’t it be better to have an ondevice cancel sound instantly after pressing the PTT for a second time. It would just drop the old task and reply to the new query when finished.
