The company has said “When we first launched voice messaging in 2013, we knew that it could change the way people communicate. By keeping the design simple, we’ve made recording and sending a voice message as quick and easy as writing a text, Every day on WhatsApp, our users send 7 billion voice messages on average, all of which are protected by end-to-end encryption to keep them private and secure at all times"

Your favorite way to chat just got better. With voice messages, you can now:
⏸️ Pause while recording - take your time when you think in Hindi but speak in English
💬 Listen while responding to other chats because when Mom needs an answer, you answer!
