Interfacing audio playback device using arduino uno.

I am trying to make a glove that converts sign language into audio outputs.

The glove will have flex sensors on each finger and would be connected to an arduino.
This is the transmitter part and I could use a bluetooth for 1 to 1 communication with another device at the receiver end.

Now I have no idea how to make this receiver that would produces a particular audio output for a particular input.

Should I use another uno at the receiver? if yes how do I configure it?
