How to Use AI Voiceovers in CapCut

CapCut is a common editing tool for TikTok, Reels, and YouTube Shorts. A clean AI voiceover workflow makes editing faster because the audio becomes the timeline anchor.

Step 1: Generate the Voiceover

Write a short script, choose a voice style, select an emotion preset, and export MP3 or WAV from ViralVoice AI.

Step 2: Import Audio into CapCut

Create a new CapCut project, add your clips, then import the generated audio file. Place the voiceover before adding final music.

Step 3: Cut Visuals to the Voice

Trim clips around the spoken lines. If the first sentence is the hook, the first visual should support that hook immediately.

Step 4: Add Captions

Use auto-captions, then correct any words that were misheard. Keep captions readable and avoid covering important visual details.

Step 5: Mix Music Lower Than the Voice

The voiceover should remain clear on phone speakers. Lower music during important words and hooks.

Export Tips

Use MP3 for quick edits. Use WAV if you are mixing multiple sounds or want higher-quality audio for the final export.

FAQ

Can I import AI voiceovers into CapCut?

Yes. Export your voiceover as MP3 or WAV, then import it into CapCut like any other audio file.

Should I add captions before or after voiceover?

Add captions after placing the final voiceover so timing matches the actual audio.

What if the voiceover is too long?

Cut filler words from the script first, then regenerate. Speeding up audio too much can make it harder to understand.
