On December 7, WhatsApp unveiled a new feature to enhance user privacy in conversations. Now, users can send disappearing voice messages that can be listened to only once. This global rollout is set to take place in the coming days. WhatsApp had already introduced a 'view once' feature for photos and videos back in 2021. 

The new disappearing voice messages will be easily identifiable with a "one-time" icon. This icon signals to the recipient that the message can only be played once. Additionally, users won't be able to forward, save, star or share these voice messages, ensuring their temporary nature and privacy. The company assured users that these voice messages come with default end-to-end encryption, ensuring a high level of security. 

The company suggests that this feature adds an extra layer of security to conversations where you prefer information not to be saved in digital form.
