How to Add AI Voiceover to YouTube Videos (Step-by-Step)

Why Use AI Voiceover for YouTube?

Recording voiceovers is time-consuming. You need a quiet room, a decent microphone, and multiple takes. AI voiceover lets you:

Generate voiceovers in seconds instead of hours

Maintain consistent quality across all your videos

Create content in multiple languages without speaking them

Skip expensive voice talent and studio time

Step 1: Write Your Script

Write your voiceover script as plain text. Keep sentences short and natural. Read it aloud first to check the flow.

Tip: Most YouTube videos use 150-160 words per minute. A 10-minute video needs about 1,500 words.

Step 2: Generate Audio with EasyVoice

Go to EasyVoice

Paste your script

Choose a voice (we recommend Aoede for narration)

Set speed to 1.0x (adjust as needed)

Click "Generate Speech"

Download the MP3

Free tier: 5,000 characters per day — enough for a 3-4 minute voiceover daily.

Step 3: Import into Your Video Editor

Premiere Pro

File → Import → Select your MP3

Drag to the audio timeline

Align with your video

DaVinci Resolve (Free)

Media Pool → Import Media → Select MP3

Drag to audio track on timeline

CapCut (Free, Mobile)

Add Audio → Extracted Sound → Import from files

Step 4: Sync and Edit

Adjust timing to match visuals

Add pauses between sections (split the audio)

Layer background music underneath (keep it at 10-20% volume)

Pro Tips

Generate in sections — don't paste your entire script at once. Generate paragraph by paragraph for easier editing.

Use different voices for different content types — a warm female voice for tutorials, a confident male voice for tech reviews.

Add captions — YouTube auto-generates them, but AI voiceover produces cleaner captions than human speech.

Speed up slightly — try 1.1x speed for more energetic content.
