The company acknowledged the problem and is issuing a software update to resolve the issue, which appears to boil down to a failure of the touch sensor on the top. >Smart speakers like the Google Home Mini are designed to only listen for a specific wake word — in this case it’s “Hey Google” or “Ok Google.” Only then do their microphones record what you’re saying it, transmit it to the cloud, and try to answer your question. But there is usually a way to just hit a button and ask the embedded assistant a question. On the Mini, it’s holding your finger down on the top of it.
