DupDub Common Mistakes to Avoid
Mistake #1: Using Standard Voices for Client Work
❌ Wrong: Picking any random standard voice for professional or commercial projects.
✅ Right: Always use premium voices for client work — they sound more consistent and natural.
Mistake #2: Uploading Noisy Audio for Voice Cloning
❌ Wrong: Recording your voice sample in a noisy room with echo or background sounds.
✅ Right: Record in a quiet space with minimal echo for the best clone accuracy.
Mistake #3: Skipping the Translation Review Step
❌ Wrong: Exporting translated videos without reviewing the transcript first.
✅ Right: Always review and edit the auto-translated text before final export.
DupDub Troubleshooting
Problem: Voice Sounds Robotic or Unnatural
Cause: You may be using a standard voice or have extreme speed/pitch settings.
Fix: Switch to a premium voice and reset speed and pitch to default values first.
Problem: Avatar Lip Sync Looks Off
Cause: Low-quality photo or the face is partially hidden in the image.
Fix: Upload a high-resolution, front-facing photo with clear mouth visibility.
Problem: Voice Clone Doesn’t Sound Like Me
Cause: The audio sample was too short, noisy, or had inconsistent volume.
Fix: Re-record a 1-2 minute sample in a quiet room at a steady volume and pace.
📌 Note: If none of these fix your issue, contact DupDub support.
