How to Add VoiceOver to PPT/PDF for Free

How do I add audio to my PPT or PDF? If you want to add audio to your presentation or other documents, this article is the ultimate guide for you. Forgo complicated tools or the high cost of speakers and let this AI dubbing tool help you.

Section1. Three Easy Methods to Make Narrated PPT/PDF

PowerPoint and PDF are a type of written text format. The first step you need to take is to convert PPT to video.

Wait, don't look for a ppt-to-video tool right away, I'll show you how to do the conversion automatically in the steps of Section2.

There are three ways you can easily add voice output to a PPT or PDF file:

Method1: Enter the spoken text, Movio will convert the text to speech and make it voice over.

This is the most effective method. All you need to do is to input the narration you want for the presentation, but the voice effects are limited (more than 200 free voices are offered on the platform), and you can not use your own voice.

Method 2: Upload an audio file that you have prepared beforehand, Movio will automatically match the audio with the presentation.

This way you can get a voice-over with your chosen voice, i.e. you can use languages that are not available on the platform or use the sounds you prepared before.

Method 3: Record the audio online and Movio turns it in the voice over for the presentation.

This is also an effective method. You can set the voice to your own tones. However, you may say something wrong while recording, which will result in re-recording the speech.


Have you figured out which method you prefer? Here are the detailed steps for these three methods.
