Upload Video

Upload your video or audio file. Supports MP4, MP3, WAV, MKV, and WebM up to 500MB. Works with any language source material.

Step 2

Auto-Transcribe

AI transcribes the audio with speaker detection. Each speaker is identified and labeled automatically with timestamps for every line.

Step 3

Translate

Select a target language and the transcript is translated automatically. Review and edit translations line-by-line before generating.

Step 4

Generate Dubbed Version

AI synthesizes speech in the target language with voice-matched or cloned voices. Download the fully dubbed video or audio file.

Dubbing Use Cases

AI dubbing for creators, businesses, and organizations reaching global audiences

YouTube Localization

Dub your YouTube videos into multiple languages to reach a global audience. Maintain your voice identity with AI voice matching. Grow your channel internationally without re-recording or hiring voice actors for each language.

Corporate Training

Translate training videos and onboarding materials for multinational teams. Ensure every employee receives consistent training in their native language. Save thousands on professional dubbing services for internal content.

Film & TV

Dub independent films, web series, and short films into new languages for international distribution. AI voice matching creates natural-sounding dubs that preserve the emotional tone and character of the original performances.

Marketing Videos

Localize product demos, explainer videos, and ad campaigns for different markets. Launch multilingual marketing campaigns faster without managing separate production pipelines for each language and region.

Educational Content

Make lectures, tutorials, and course materials accessible in multiple languages. Help students learn in their native language. Process entire course libraries with batch dubbing via the API for large-scale educational platforms.

Social Media

Dub TikTok, Instagram Reels, and YouTube Shorts into trending languages to maximize reach. Quick turnaround for time-sensitive content. Reach audiences in markets where your original language content would never gain traction.

Dubbing Features

Advanced AI capabilities that make TTS.ai the most powerful dubbing platform available

Speaker Detection

AI automatically identifies and labels individual speakers in your content. Each speaker gets their own voice assignment, ensuring multi-speaker conversations are dubbed naturally with distinct voices for every participant.

Voice Matching

Clone each speaker

30+ Languages

Dub content into over 30 languages including English, Spanish, French, German, Chinese, Japanese, Korean, Portuguese, Arabic, Hindi, Russian, and many more. Cross-lingual voice cloning preserves speaker identity across all supported languages.

Background Audio Preservation

Isolate and preserve background music, sound effects, and ambient audio from the original. The dubbed speech is mixed back with the original background track for a professional, seamless result.

Why Choose TTS.ai for AI Dubbing?

End-to-End Automation

Traditional dubbing requires transcription, translation, casting voice actors, recording sessions, and audio engineering. TTS.ai automates the entire pipeline. Upload a video, choose a language, and download a fully dubbed version in minutes instead of weeks. Editable transcripts give you full control over the final translation.

Fraction of the Cost

Professional dubbing studios charge $50-200+ per minute of content. TTS.ai costs just 4 credits per minute with voice matching included. Dub a 10-minute video into 5 languages for less than a single minute of studio dubbing. Perfect for creators and businesses on a budget.

Full Editorial Control

Review and edit every translated line before generating the dubbed audio. Fix mistranslations, adjust phrasing for cultural context, or rewrite sections entirely. The editable transcript puts you in control of the final output while AI handles the heavy lifting of voice synthesis and timing.

API for Batch Processing

Need to dub hundreds of videos? Use the TTS.ai API to automate dubbing at scale. Submit jobs programmatically, receive webhooks on completion, and download results via API. Perfect for media companies, e-learning platforms, and content distribution networks handling large video libraries.

Frequently Asked Questions

Upload a video or audio file. Our AI automatically transcribes the speech, detects individual speakers, translates the transcript to your target language, and generates new speech in the target language with voices matched to the original speakers.

Dubbing supports 30+ languages including English, Spanish, French, German, Chinese, Japanese, Korean, Portuguese, Italian, Russian, Arabic, Hindi, Dutch, Turkish, Swedish, Polish, and more.

Yes. With the "Match original voice" option, the AI uses voice cloning to create a synthetic voice that sounds like the original speaker but speaks in the target language. This maintains speaker identity across languages.

Upload MP4, MKV, WebM, MP3, or WAV files. For video files, the dubbed audio is synced back to the video. Maximum file size is 500MB.

Yes. After automatic transcription and translation, you can review and edit every line. The transcript editor shows timestamps, speaker labels, original text, and editable translated text side by side.

Our AI uses speaker diarization to identify who speaks when, even with multiple speakers talking in the same recording. Each detected speaker is assigned a label and can be mapped to a specific target voice.

Yes. When enabled, the dubbing process separates speech from background audio (music, ambient sounds) using AI source separation. The dubbed speech is mixed back with the original background audio.

Processing time depends on the video length and quality settings. A 5-minute video typically takes 3-5 minutes to process on the Balanced quality setting. High Quality mode takes longer but produces more natural results.

Currently, one target language per dubbing job. To create versions in multiple languages, submit separate jobs for each language. Each job can use the same source file.

The AI adjusts speech speed and pauses to match the timing of the original speech segments. This ensures dubbed speech fits within the same time windows. Full visual lip-sync manipulation is on the roadmap.

Dubbing costs include STT (2 credits/min), translation, and TTS (2-4 credits/1K chars depending on model). A 10-minute video costs approximately 50-100 credits. Background separation and voice cloning may incur additional costs.

The individual components (STT, translation, TTS, voice cloning) are all available via API. The full dubbing pipeline with speaker detection and timing alignment is available through the web interface, with API support planned.
