Choose a setting where you can listen
A voice conversation works best when you can hear the other person and speak without sharing the room with an audience. Headphones can reduce echo and protect the conversation from nearby listeners. Before entering, close other apps using the microphone, check the selected input device and move away from a fan or loud street if you can. Those small steps matter more than sounding polished. You do not need a perfect setup; you need a setting where both people can understand each other.
