    Have you considered using WinBond's ISD17xx family?

    The audio quality is quite good at the 12kHz sample rate. It can be controlled in serial mode or in "push-button" mode. I have a PIC controlling two of these (ISD17180) at the same time in PB mode.

    Unamplified volume is very good with a speaker driven directly from the complementary PWM output.

    "Easy to use" is easy to say.
