General Usage Tips

TLDR: Want to get the best out of Speakflow? Check out this guide

If you're using Flow mode, it's important to speak clearly and at a volume loud enough for your microphone to hear you.

Minimizing eye movement
As you read, your eyes move left and right. When presenting on camera, you'll want to minimize this by setting the width of your script to be relatively narrow.
Width sliders

Drag either of the pink buttons along the slider, to change the width of your script. Also, make sure that you aren't too close to the camera. 

Avoid looking stiff
Most people use their hands, move their heads, use vocal inflections, etc when speaking. But when using a teleprompter, people often stiffen up – they don't move their heads, and use their "reading" voice. 

When you're using Speakflow, avoid looking stiff by trying to remain natural looking – move your head, don't use your "reading voice", and don't be afraid to adlib here and there. 

Overall, looking natural while using a teleprompter takes practice. Be sure to rehearse your script to become familiar with it.
