The SayIt by nVoq subscription includes a wireless microphone app for your iPhone and Android. With this app you can turn your phone into the microphone input on your computer.
To enable this option you will need to checkmark "wireless microphone" under the options menu.
After enabling the wireless microphone option, a window will popup to ask you to accept or name your computer to assist with proper connection to your smartphone.
After you have done this, download the "SayIt Wireless Microphone" from the app store. You will need to login to your SayIt account on the app to begin.
Once logged in you should be automatically connected to your PC. You will know this if the computer name is at the top of the app. If not, you can click the connect to client button at the top.
Once connected you are all set to begin dictating with your phone into your target application.
