How to Add Voice to an iMessage from Your iPad
With iOS 8, you can record an audio message and send it along to a recipient. Apple calls this Tap to Talk and here’s how to take advantage of it.
Press and hold down the microphone icon to the right of the text-entry field (not the microphone icon on the iPad keyboard) and start speaking. Your voice appears as a waveform at the bottom of the screen, as shown.
When you’ve finished speaking, keep your finger pressed down and swipe up to send the message. You can listen to the audio before sending it by tapping the play icon, which appears after you release the button you held down to record. If you’re not thrilled with what you’ve just recorded, swipe left instead to cancel.
The recipient of your recorded iMessage will be able to tap a Play button to listen to what you had to say. But in some cases, he or she had best listen right away because you can set things (in Settings) so that audio messages expire after two minutes. Your only other option is for the message to never expire.
Keep in mind that the microphone icon that lets you record your voice will be enabled only if you’re sending an iMessage to a chat partner.
