Yes, I have the same problem, we used to have four different voice for each person in the household, so I will know if Google Assistant recognize the right person, but now is not working at all, apart from the fact that in the Google home app the preview for each voice sound always the same, also now if anyone changes the voice on their Google Home app it changes for everybody else too... So basically now there is only one voice for everybody. Also now randomly it doesn't recognize who is speaking even if we re-train for our voices over and over. Before Gemini when we used Assistant it recognizes each of our voices perfectly... But it mistook our requests a lot... Now it seem to understand better what we say, but it randomly forget the correct thing to do even if it did it just few requests before, like not being able to show a list of things that few minutes before it did just fine, going to the extent if saying that it cannot do that and it never did, or not being able to tell me where is a store near me where I can by something, like it shows me the store picture, name, address, phone number and business hours, while at the same time saying that it cannot do that, or there are no stores near me of such kind. This Gemini it so bugged... It just good to chit chat about BS without important meaning, because it is not factual nor reliable what so ever. At least Google Assistant was not that smart and and sometime could understand very well but when I did it actually give you actual factual information.
