Introduction

Matching the right voice to a speaker is crucial for authenticity. Whether you have a male speaker needing a deep baritone or a female narrator requiring a soft, professional tone, VideoDubber's vast library and cloning capabilities ensure you always have the perfect match.

Step-by-Step Guide

Step 1: Upload Your Video for Translation

Start by uploading your video to the translation interface. You can set the number of speakers here, which helps the AI separate different voices in the source footage.

Upload Interface
Upload your video and select the initial settings, including the number of speakers.

Step 2: Select and Change Voices

VideoDubber offers two distinct ways to control speaker voices—either immediately after uploading or during the editing phase.

Right after uploading your video, you can assign voices to each detected speaker before the initial translation even begins.

Upload Phase Voice Selection
Select speaker voices immediately after upload for a seamless start.

If you need to make changes later, you can swap voices at any time within the editor interface while redubbing or editing subtitles.

Editor Voice Selection
Fine-tune your voice choices directly in the editor for precise control.

When selecting a voice, you have regular and advanced options to suit your needs:

  • Off: The default selected voice is applied without any cloning effects.
  • Instant Voice Cloning: Applies the style of the selected voice but adapts the tonality from the original speaker in the video segment.
  • Pro+ (Premium): Allows you to upload a custom sample—such as a celebrity voice or a clean studio recording of your own voice—to clone that specific tonality.

Step 3: Review and Export

After assigning the desired voices, preview the result. The AI ensures perfect lip-syncing with the new voices.

Voice Selection
You can also adjust specific voice clone settings while redubbing or editing in the editor.

Once satisfied, you can proceed to export your video.
