Seeking advice for a pressure-switch-operated speaker.

I built a greenhouse. My wife and I are super into Harry Potter. I want to set up a thing where -when the greenhouse door is opened- a speaker plays the “welcome to greenhouse three, second years!” sound byte from the second movie. Can you all help me understand the components that will be needed for this? I know I need some type of pressure switch and a speaker but I don’t understand the memory hardware situation and how it communicates with the speaker. I have basic electrical knowledge, I know how to wire switches and I have some experience soldering electronic components. Thanks for any help!
