If the reports are accurate, Reddit is the latest tech company to explore bringing voice chats into its site. The service is "quietly exploring" moderator-run voice chats, similar to what Clubhouse offers. But according to Mashable's source, its development is still in the early stages and described as confidential. Reddit hasn't commented on the rumoured feature.
This potential function might be part of Reddit's power-ups program, which it announced in August 2020. This "experiment" offers extra features for subreddits whose members buy "a minimum threshold of power-up subscriptions." Some additional features include the "ability to upload and stream up to HD quality video" and "inline GIFs in comments."
