Facebook is booming out day by day with its special features. You just have to tap the microphone icon, record the message and send and your audio clip. The tool listens to the full audio clip and posts a typed version below the audio, according to media reports. The tool has been sent for a test group. Facebook has already its attractive features including the Facebook stickers, now one more feature is likely to be added. "We are always working on ways to make Messenger more useful. Facebook is offering a feature that lets people send voice clips to their friends without having to type the text," said David Marcus, vice president of messaging products at Facebook.
