Step 1: Launch the app you want to use, for e.g. Messages, Mail, Twitter, Facebook, etc.
Step 2: Bring up the keyboard by tapping to type a message.
Step 3: Tap the Microphone icon appearing between the Space bar and the keyboard switcher.
Step 4: Speak the message that you want to enter, and tap Done.
Step 5: iPhone will translate the speech-to-text in few seconds.
I feel that it would have been cool if the iPhone could automatically enable Microphone when we bring the phone to our ear (similar to 'Raise to Speak' feature in Siri) while the keyboard appears on the screen. This feature is still in it's infancy. I noticed that it can only listen for about 48 seconds continuously and then it automatically stops and converts those 48 seconds to text.
What do you think of this feature? Did you find any cool tips while using this feature? Share with us in the comments section.
