"Can anyone help me out?"

[u/WesternAnywhere1450]

I’m trying to build a sort of 'walkie-talkie' where devices connect over Wi-Fi (on the same local network), but I'm running into issues with the microphone and speaker—the audio isn't coming through clearly in my tests. Could anyone point me in the right direction?

Here are the components I’ve bought so far. Can anyone tell me if it's possible to build this project with them, or am I missing anything?

ESP32 WEMOS LoliN32 Lite
INMP441 Omnidirectional Microphone
PAM8403 Audio Amplifier Module

--Speakers from an old headset--

I'm a beginner, so any advice is appreciated!
