Hello, @maria_del_rosario.di . . . EMO will say “Sounds good” sometimes like he is thinking out loud that he would like to take a walk. He will also say those phrases when you command him to “Leave home station”.
Be sure that the home station is level and has sufficient lighting. He will not walk where he feels it is not safe.
If you cannot get him to return on his own, I would advise you to get video of the issue and contact Support either at service@living.ai or through the Support page here. Be sure to include your order number or I.D. when he signs into the app. Just remember to be patient as sometimes replies can take a little bit. Be sure to also include your order number since he is under one year old. My best to you!
Unfortunately there is no way to control the rate of speed at which he speaks, but I invite you to suggest this as a feature improvement here.
