If you want a lot of buttons, you might want to check out the Adafruit NeoTrellis M4 Express. 32 buttons of multicolored glory and 8 megabytes of file storage provides for lots of capability. The flash size means each button cannot read a whole book but words and phrases certainly will fit with room to spare.

If you do not have 32 sounds, load up the number you have.

Now you can use NeoTrellis as a sound box. Say someone is having voice issues. Load up the words you want, print out a guide to which button does what, and you have a communications device!
