What components to use for Speaker and Microphone.

 I want to create a nice toy where I want to put LLM so that the child can talk to it. I am zeroing down on various components. I have zero hardware experience, so based on my research, I'm using Raspberry Pi 4 with 2GB RAM, LEDs, and buttons. 
 
 I'm not able to figure out the best microphone and speaker for the same. Can you guys suggest me?
 It should have the ability to play music as well.
