AUDIO MESSAGES
Tap to Talk allows you to send audio messages to fellow iPhone users. You can activate this feature in one of two ways: either lift the phone to your ear and begin speaking while composing a text, or tap and hold the microphone icon to the right of your text-entry box. If you choose the tap-and-hold option, a dial will appear. Lift your finger and press the play button to preview your audio, the arrow to send your recording right away, or the X to delete it.
