Click the MICROPHONE icon and speak.

Your speech will be converted to text and will be displayed in the text box. Enjoy!

Notes:

• You must have a mic & be using the latest Chrome browser- any version above v28.0.1500.72, I believe.
• Chrome may prompt you to ALLOW/DENY microphone access. You need to hit ALLOW for this to work.
