An Australian man's voice is whispering the spelling words, while his "assistant" writes the words with a fine point marker on paper. Autonomous sensory meridian response (ASMR) - All the spelling words are Australian slang words that are positive words (i.e. words that mean good or great or excellent or true or well done). Each word is quietly whispered and then written on piece of paper using a fine point marker. This video has a mixture of writing and soft talking.
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
