I would prefer not to hear the vacuum speak especially at night because it is very loud and disturbing. I don’t really like the voice talking in the daytime either. It randomly says “starting to charge” when you walk past it sometimes and can wake people up at night. There should be a setting where you can disable the voice alerts completely or have an option for it to be silent at certain times. Maybe a do not disturb setting where your can configure certain times of the day for it to be silent.
