Adding a voice-over to narrate a family history slideshow is a simple but effective way to enhance the storytelling value of your production. ProShow offers two ways to include audio narration in your slideshow. You can import pre-recorded audio files if you have them ready to go. If you have a USB microphone hooked up to your computer, you also have the option of recording voiceovers directly into your show. At any time, you can use ProShow’s built-in tools to trim and edit the timing and volume of these audio tracks. For more details, watch the video below.
