From Amazon:
We heard you loud and clear! Samuel L. Jackson celebrity voice just got easier to use. Now you can simply say “Hey Samuel” to ask for jokes, weather, and more. To get started, just say, “Alexa, introduce me to Samuel L. Jackson” and choose the “Hey Samuel” wake word. You will still be able to use Alexa’s default voice just as you do now. Check below to see if your device works with “Hey Samuel”.
Already have Samuel L. Jackson celebrity voice? You can set up “Hey Samuel” by saying “Alexa, enable ‘Hey Samuel’”.
GET STARTED WITH SAMUEL – Samuel L. Jackson is here to add extra personality to your Alexa experience. Just ask and Samuel will set a timer, tell you a story, and more.

“Hey Samuel, what’s the weather?”
“Hey Samuel, tell me a joke.”
“Hey Samuel, set an alarm for 7am.”
