Facebook-owned WhatsApp has been working on revamping its voice messages feature. Like on Instagram, the chat app plans to show real-time waveforms while you're recording a voice message. And it will give you the option to stop recording and listen to what you plan to send, an option that isn't currently available on WhatsApp.
The company is testing it out for iOS and Android, but it hasn't been made public yet. But WABetaInfo got their hands on a demo, which you can check out here. Another feature users can look forward to in the future is multi-device support, according to Facebook CEO Mark Zuckerberg.
