Hello, Roe! Depending on what model your Vizio is, you can connect an Echo Dot to your TV. If your TV is compatible, follow these steps to pair your TV with VIZIO's Amazon Alexa skill for SmartCast TVs: 1. Press the VIZIO button on your remote to launch SmartCast TV Home on your TV. 2. From the top menu, navigate to Extras and click OK. 3. Highlight and select "Amazon Alexa". 4. Follow the onscreen steps to pair your TV with your myVIZIO account and enable the Alexa skill. I hope that helps. Have a great day!
You do not need the Dot for the Echo to Work. I have an Echo at home and purchased the Dot to have at my office. It works great once I could get the wifi connected.
Yes. My sister speaks to it in English and Spanish.
