How to Set a Sleep Timer on Alexa and What It Is
This is so easy that it doesn’t even require any steps. Whenever your Echo device is playing music, a podcast, or other audio, simply wake up your Alexa device and tell it to set a sleep timer for (length of time). Like this: “Alexa, set a sleep timer for 30 minutes.”
The response is 'Okay' and the timer duration is repeated.
