With this feature enabled, your text will stop scrolling when you are silent.
Click on the "Teleprompter Settings" icon on the upper right side
Turn on the "Pause on silence" option and go back to Teleprompter's screen.
Set the pause icon near the noise level bar.
To make sure that Pause On Silence will work seamlessly, use the Reference Noise Level. You can change the reference noise level by moving the reference slider.
If you are filming in a noisy setting, set a high reference noise level, so that the app knows to stop even if there is noise around.
If you are filming in a quiet setting, set the reference noise level to low, so that the app stops scrolling only when you are completely silent.
