Interesting topic… Although, I know just as many sighted people who have smart speakers as I do blind people. I’m not very concerned about the privacy issues as the same issues arise if you have a smart phone with Siri or OK Google enabled. This may sound like paranoia, but I’m actually convinced the phone is paying attention even when it’s locked. As an example… I was talking with someone a couple years ago about a particular bank, and why I elected not to become a customer. The next day, what appears on my Facebook? Several ads for that bank. Ads for that bank showed up for several weeks afterwards as well. Keep in mind at that point, I’d been on Facebook for about six years, and had never seen ads for that company prior to my conversation. Someone’s phone was listening. With regards to the smart speakers, I do think you may become more vulnerable if you have smart home settings enabled. Have not messed with that yet, though and considering getting a couple of smart outlets for some of the lamps in the house since the cited folks are always forgetting to turn them off. Right now, I use my echo device mostly for music, news, sports radio… So, if anyone is listening, all they are hearing is the number of times I tell it to play a certain artist. Seriously though, if it’s always listening as some have speculated, so is your phone. Really, the only way to avoid it would be to go off the grid completely.
