Sound signal (word) to the intersection of the beam of the photorelay (IR diodes, photodiodes)?

Can you help?

Photorelay, instead of a diode, it is necessary to somehow put a device for outputting an audio signal (word). (I saw the implementation of voice acting on Attiny). How to do it?

The easiest way is to screw some chip from the ChipCorder family from Winbond there. Here is an article on the topic.
