I will say, for the sake of combating misinformation about Judaism, that people who keep Shabbat traditionally, but also use voice activated technology on Shabbat are extremely rare, if they exist at all. I have never heard of someone who actually adheres to this practice despite living in a community that is on the extreme liberal end of Shabbat observant Jews[0].
[0] Which is where you would expect this to happen if it actually did.
If someone reading this keeps Shabbat traditionally and uses voice activated technology on Shabbat (or knows someone who does), please speak up. I would like to hear about your practice. Otherwise, I would prefer to avoid giving the impression that this is a position that anyone holds. There is far too much misinformation present in this thread already.
