How to Dub Your Videos into Multiple Languages with Wavel AI

Expanding your video content to international audiences used to mean hiring voice actors, booking studio time, and managing complex post-production workflows. With Wavel AI, you can dub an entire video into a new language in under an hour. This tutorial walks you through the complete process.

Step 1: Upload Your Video

Log into your Wavel AI dashboard and click New Project. Upload your video file (MP4, MOV, or AVI) or paste a YouTube/Vimeo URL. Wavel AI supports videos up to 2 hours long. The platform will automatically extract the audio track and begin transcribing the spoken content. You’ll see the transcription appear in the editor within minutes, with speaker labels and timestamps.

Step 2: Review and Edit the Transcription

Accuracy at this stage is critical — the quality of your final dub depends entirely on the source transcript. Read through the auto-generated transcription and correct any errors. Pay special attention to proper nouns, technical terms, and brand names, which AI transcription often mishears. You can play back any segment by clicking the timestamp to verify the text matches the audio.

Step 3: Choose Your Target Language and Voice

Select your target language from the dropdown menu — Wavel AI supports 40+ languages including Spanish, French, German, Japanese, Korean, Arabic, Hindi, and Portuguese. Next, choose your voice strategy. If you want the dubbed version to sound like the original speaker, enable Voice Cloning. This works best when you have at least 2 minutes of clear speech from the speaker. Alternatively, browse the Voice Library of 250+ AI voices and select one that matches the tone and character of your content.

Step 4: Generate and Preview the Dub

Click Generate Dub and Wavel AI will translate the transcript, adapt the speech timing to match the original video’s pace, and synthesize the dubbed audio. This typically takes 5-15 minutes depending on video length. Once complete, use the Preview Player to watch the dubbed video. Listen for natural phrasing, correct pronunciation, and proper timing. If any segment sounds off, click on it in the timeline to adjust the pacing, pronunciation, or emphasis.

Step 5: Export the Final Video

When you’re satisfied with the dub, click Export. Choose your output format: dubbed video with the new audio track, separate audio file for manual editing, or subtitle file (SRT/VTT) for the translated text. For YouTube uploads, export both the dubbed video and the SRT file — upload the dubbed video as a separate language track and the SRT as closed captions for accessibility.

Pro Tips

• For voice cloning, provide the cleanest possible source audio — remove background music and noise before uploading for the best cloning results
• Always have a native speaker review the dubbed output for cultural nuances and idiomatic expressions that machine translation may miss
• Use the batch processing feature to dub an entire course or video series in one session, saving significant time over individual uploads
