I have lost due to time-outs, but the voice would only have served to cause me to “throw a stone on the board” rather than make a play. When I get timed out is when I am in a position where I cannot decide what to do. An amateur illness, to be sure, but a point I still manage to reach occasionally. The visual cue seems to be sufficient because it doesn’t startle me.
Ultimately, though, it is a choice between a rock and a hard place.
