Since Twitter tested Spaces with a limited number of users or groups which has been introduced last year, now Twitter Spaces is available to everyone who has at least 600 or more followers on their Twitter accounts. Twitter Spaces is a new way to start an audio conversation with someone else on Twitter.
So, how Twitter Spaces work on iOS and Android when someone you follow starts or speaks in a Space, it’ll appear at the top of your timeline as a purple bubble for as long as it’s live. When you join a Space as a listener, you can react to what you hear with emojis, check out any pinned Tweets, follow along with captions, Tweet or DM Space, or request to speak.

When you join Space as a speaker, in addition to talking, you can pin Tweets to Space, turn on captions so everyone can follow along with what you’re saying, and Tweet Space so your followers can join. When you create a space, you’re in control – who’s speaking, the topics, and the vibe. Invite people to join by Tweeting or DM’ing them to jump in and then invite them to speak directly from your Space. From there, talk about whatever is happening in your world.
