Step 2 – Input or Import Your Script
There are multiple ways to load your content:
-
Type or paste your script directly.
-
Import TXT, DOCX, or PDF files.
-
Upload audio/video files to auto-transcribe.
-
Paste YouTube or TikTok links for subtitle generation.
If you’re starting from scratch, use DupDub’s built-in AI Writer to help brainstorm and write your script.

Step 3 – Select Your AI Voice
In the Voiceover Library, you can filter voices using the following criteria:
-
Language & Accent
-
Gender
-
Age
-
Quality (Standard, Premium, Ultra HD, etc.)
Alternatively, you can choose voices based on content type from the left-side panel, such as:

-
Travel Guides
Click the play icon to preview voices instantly. After selecting a voice, you can set its emotional tone (e.g., Happy, Neutral, Sad) if that voice supports multiple emotions.
