Hi there! The TU7000 Works With Amazon Alexa - when your device is connected, you can use Alexa to change channels, swap input selections and launch partner apps. When stepping up to the TU8000, you will gain the built-in Amazon Alexa with a voice control button on your remote. This will allow for a wider list of commands.
