How to Create Random Voice Messages

Hello guys,

I am a beginner, but I want to create something very nice to my girlfriend and I was thinking in a plushie with a random audio generator based on some phrases I have to her here. I discovered that Arduino is capable to do that because of this video:

Is there any way I can do that, but with random phrases that will come up when she interacts with the plushie?

I already have all the phrases I want here and I got the video idea, but I don't know how to do with more than one phrase and in a random way.

Thank you so much for the help.

Record the phrases to an SD card, one track per phrase, use an MP3 player like the DF Player Mini, play a random track using the random() function (don't forget to set a randomSeed() or you get the same order time and again).

Thank you wvmarle.
