Question: do you need a smart tv for echo?
Answer: If you've got an Alexa device like an Amazon Echo, or Echo Dot, you'll be able to use it to control your TV with your voice - and the best thing is, you don't even need a smart TV. Most older smart TVs don't support voice assistants like Alexa, so even if you've got a smart TV, it might not have 'Alexa Skills'.
