Adding voiceovers to PowerPoint presentations can instantly boost engagement and help deliver your message with more clarity. But recording your own voice isn’t always practical — maybe you’re not confident on mic, or you need to scale audio for multiple slides fast. That’s where AI voice technology steps in.

In this article, we’ll introduce you to the best text-to-speech AI available today and how you can use it to create professional, natural-sounding audio for your presentations. We’ll also show you how to easily embed audio into your PowerPoint slides.

Why Use Text-to-Speech AI in PowerPoint?

  • Save time: No need to record and edit your voice manually.
  • Consistent tone: Perfect if you're building templates or training decks.
  • Accessibility: Helps make your presentation more inclusive for all audiences.
