Best approach for Halloween special effects audio

For Halloween I used Home Assistant to automate some simple special effects for trick-or-treaters, including playing a ghoulish laugh, all triggered from our doorbell.

To play the laugh, the automation sent a notification to the Home Assistant app on a mobile device synched with a Bluetooth speaker. It worked reasonably well, though not perfectly.

Is there a better method (that doesn’t require expensive hardware) for HA to play occasional, brief audio over a speaker?

Thanks.
