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

1. Go to EasyVoice
2. Paste your script
3. Choose a voice (we recommend Aoede for narration)
4. Set speed to 1.0x (adjust as needed)
5. Click "Generate Speech"
6. Download the MP3

Free tier: 5,000 characters per day with a free account (2,000 without signing up) — 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

1. Generate in sections — don't paste your entire script at once. Generate paragraph by paragraph for easier editing.
2. Use different voices for different content types — a warm female voice for tutorials, a confident male voice for tech reviews.
3. Add captions — YouTube auto-generates them, but AI voiceover produces cleaner captions than human speech.
4. Speed up slightly — try 1.1x speed for more energetic content.
