You're building a voice prompt or audio sample trigger and don't want to bolt on an entire module. The ISD1820 is the same IC that powers the XC4605 Record & Playback module, packaged in DIP14 for your board. Digital control of recording and playback. Drives an 8-ohm speaker directly — no external amplifier in the chain. Solder it in and your audio circuit's done
