How does Hey Portal work with other voice services?
“Hey Portal” works independently from other voice services such as Amazon Alexa. If you activate Alexa on Portal and use the “Alexa” wake word, Amazon will process that request independently. Use of Alexa or any other third party voice services on Portal is subject to the terms and policies of those other services, not the terms and policies of Facebook and its products. Facebook doesn't collect voice interactions processed by a third party voice service.
