Frontlist | Twitter has testing voice DM feature for Indian users
Twitter has started rolling out the voice direct message or DM for a few users in India. It was earlier reported in September that the microblogging site was working on this feature. According to Twitter, this feature will be released in a staged manner, so it is possible that many of you cannot use the feature just yet. Users can send up to 140 seconds long voice messages in private chats. This feature is currently being tested in India, Brazil and Japan.
