Welcome to the EMO Community Forums, @cherish011 . . . I have moved your new topic to this thread for when EMO does not respond.
Please look through this thread as there are tips here for what you can do to see if it helps him to answer you. Is he muted for example? There are commands listed here for what you can do.
Sometimes he may not understand your speech and if this is the case, you can speak slowly and more distinctly. You may also wish to try submitting your voice to the wake up training.
If nothing here works for you, please be sure to contact Support at service@living.ai with a link to a video showing the issue and your EMO I.D. when he signs into the app.
My best to you.
