The voice in this clip comes from the standard spoken prompts of an automated external defibrillator, the portable device used in first-aid and CPR training to guide a rescuer through analysing a heart rhythm and delivering a shock. These prompts are deliberately calm and instructional, which is why they translate so well to comedy. Online, the analysing sequence became a favourite audio for revival memes, where creators stage an over-the-top collapse and let the device narrate the 'resuscitation'. Its staying power comes from the format: any video with a fake faint, a comeback or a dramatic recovery can be upgraded by dropping the AED voice over it.
About this sound
The AED defibrillator voice prompt saying 'analysing' and 'shock advised' from CPR training audio. Creators use it in meme revival edits and prank fail videos.
This clip captures the calm, robotic voice of an automated external defibrillator running through its analysis sequence, announcing that it is analysing the heart rhythm and that a shock is advised. Flat beeps and measured pauses sit between the prompts, giving it that unmistakable clinical tension. The contrast between the dead-serious medical delivery and whatever silly thing is on screen is exactly what makes it funny. Played over a friend dramatically 'reviving' after a joke, it turns a flat gag into a full emergency-room scene, and the longer the analysis drags on, the bigger the payoff when the verdict lands.
