Clubhouse competitor Twitter Spaces has been available to a wider audience since Monday.
Users with more than 600 followers can now use the audio feature.
Spaces was previously available to a limited number of test users.
It is not yet known when the function will be available for all accounts.
The intention of Spaces is that people can create a kind of chat room, where users can then talk to each other.
People can listen in on the conversation, but only the person who created the room can determine who is speaking.
Twitter isn't the only tech company that sees potential in a Clubhouse-like concept. For example, Discord, Facebook, Slack and Spotify and LinkedIn are developing their own versions of the app.
