Twitter has primarily been a text-driven social platform but it hasn't shied away from experimenting with new formats. Earlier this year, the company rolled out Fleets, which allowed users to share fleeting thoughts and moments — a feature not-so-loosely inspired by Snapchat and Instagram. Now, Twitter is testing audio chat rooms in its latest experiment called Spaces.

This isn't the first time that the platform has tested out a voice-based feature though — you can already create voice tweets on the iOS app. However, Spaces is different in that it aims to create a "space" wherein a group of people can speak at once.
