Sound input levels can make a big difference of how the other part hears you, so try to take a few minutes in the beginning to adjust them.
Note that if you stand further away, you might need to speak a bit up to compensate for the distance.
You can adjust your input level for your built-in or external microphone by launching 'Settings', going to 'Sound' and under 'Input' drag the Input volume to the desired position or percentage.
On Windows 8 or 10:
- Move your mouse to the lower-right side of the screen to open the Windows Charms Bar menu, choose Settings, select Control Panel, and click on Hardware and Sound.
- Click on Sounds.
- Select the Recording tab
