According to Google’s Subprocessor List, they added LXT AI Inc. for voice to text processing services who are based out of Canada, India, Romania. According to LXT’s website, they may be actually using this data for AI training… This sounds very concerning. Anything you say will be sent to AI company’s servers, and essentially be their property… So if you’re using Voice to Text to pitch a new idea or game designing docs… They can steal it? is that how it works?
iOS literally prompts you to provide permission for that when you first start up your phone (either restore, or first use). So either you opted in or out but they’re pretty transparent about it.
I don’t have any of those devices, but I have observed the test I described showing the voice recognition being performed.
