How to Add AI Voiceover for Countdown and Teaser Videos in CapCut
Creating teaser or countdown videos that grab attention often comes down to one key detail—voiceovers. A strong voiceover can set the mood, build anticipation, and make your video feel professional, even if it’s just 15 seconds long. But hiring a voice actor or recording your own isn’t always ideal, especially for students, marketers, or small creators on a tight budget.
That’s where CapCut Desktop’s AI Voice Generator steps in. This feature makes it easy to add high-quality voiceovers to any countdown or teaser video, without needing microphones, recording studios, or expensive tools. Whether you want a dramatic intro like “3…2…1… Get ready!” or a soft-spoken teaser for a product drop, CapCut’s AI Voice Generator has you covered. Let’s explore why this tool is perfect for your countdown and teaser videos—and how you can use it in simple steps.
Why Use AI Voiceovers for Countdown & Teaser Videos?

How to Add AI Voiceover for Countdown and Teaser Videos in CapCut
Ready to level up your teaser videos with professional-sounding narration? Follow these 3 simple steps in CapCut Desktop Video Editor.
Step 1: Launch CapCut and Start a New Project
Open CapCut Desktop Video Editor on your PC or laptop. Click “New Project” to start editing. Import your teaser or countdown video clip into the timeline using the Media panel. If you haven’t made the video yet, you can also build your teaser from scratch using CapCut’s drag-and-drop features, templates, and animated text.
Step 2: Use the AI Voice Generator Tool
This is where the magic happens. In the text panel, click Text to Speech AI feature. Type your countdown or teaser script in the input box. Example: “Get ready! Only 10 seconds to go…”
Choose from the available voice options (male, female, dramatic, robotic, calm, etc.). Click “Generate Voice” and wait a moment while the tool creates your voiceover. Once done, the voiceover audio will appear in your project timeline. Preview different voices before finalizing. Some voices work better for energetic countdowns, while others are more suited to subtle teaser tones.
Step 3: Sync and Finalize Your Voiceover
Now it’s time to make sure your voiceover matches your video perfectly.
Drag the voiceover clip in the timeline to line up with your countdown or visuals. Adjust the volume, timing, or speed if needed. You can also add background music, sound effects, or on-screen text to match your voiceover.
Once you’re satisfied, click “Export” to save your video in your desired format and resolution. If you’re creating content for Instagram, TikTok, or YouTube Shorts, you can select vertical export settings for improved engagement.
