SleepCancel

Cancels sleep mode for the specified/assumed/elicited player.

If the sleep fade-out had already commenced when you requested cancellation, it will just continue as it cannot be stopped. If that happens, Alexa will still say that cancellation was requested but it will nevertheless be ignored by the LMS server.

Invocation options (choose based on grammar-fit):

Alexa, [ open / start / launch ] MediaServer
Alexa, [ ask / tell ] MediaServer [ to / for ] …

{end} can be any of deactivate/disable/turn off/cancel.
