If you’re sending out your presentation instead of giving it in front of an audience, but you feel adding a vocal explanation would better help to deliver the message, record a voiceover narration. Here’s how to do it. First, you’ll need a microphone. Most modern computers have a built-in microphone that gets the job done, but investing in a USB microphone will increase the audio quality of the narration by quite a bit. The built-in microphone will be set as your input device by default, so if you plan on using it for the PowerPoint narration, you don’t need to take any additional steps in setting it up. However, if you plan to use a USB microphone for the narration, be sure to set it as the input device.
To do this on Windows, right-click the volume icon found on the right of the taskbar. In the menu that appears, select “Open Sound Settings.”
In this example, we’ll choose “Record from Beginning.”
