Voice typing in WhatsApp is easy if you have the Gboard installed. Open the chat and locate the mic button on the keyboard. Tap the mic button and allow it to access your phone's microphone. Next, tap on the mic button and voice out your message. The message will be converted to text. Hit send if you are satisfied with the output. Most Android phones usually come installed with Gboard as the default keyboard. However, if your phone doesn't have Gboard installed, you can click here to install it from the Play Store.
