Here in this post, we will walk you through everything about what dubbing is—from basic definitions to practical tips for dubbing a video or becoming a voice actor. Let's dive in to clearly understand what dubbing is and how to create your own dubbed content easily.
What is Dubbing: The Basics
At its core, dubbing is the post‑production process of replacing the original spoken dialogue in an audiovisual work with a newly translated version.
The dubbing process is widely applied in film, series, animation, game, documentary, marketing video, etc. A dubbed video makes the target audience experience the content as if it were originally produced for them.

Key Benefits of Dubbing:
- Similar to subtitles, dubbing breaks language barriers with language translation and cultural adaptation, making content understandable to audiences who don't speak the original language. Both can reach a wider audience and markets.
- While dubbing unifies character voices with video subjects to create a higher immersion than reading subtitles, especially for children, the visually impaired, or those who prefer to multitask.
Quick Comparison of Dubbing vs Subtitles vs Voice-over:
Dubbing | Subtitles | Voice-over | |
Key Features | Full replacement for original dialogue, with lip-sync technology or at least timing alignment. | Added text only while keeping the original audio. Cheaper than dubbing. | New audio layered over original. The original is often audible. |
What is the Development of Dubbing
The brief history of dubbing
- Early Talkies (Late 1920s–1930s): With the arrival of sound films, studios scrambled to reach international audiences. Some even re-shot entire movies in multiple languages before true dubbing methods took shape in Europe (France, Germany, Italy, Spain).
- Growing Industry (1930s–1950s): Dubbing became standard practice in Europe, often supported by government policies that promoted domestic language versions.
- Analog Era (1960s–1980s): Advances in magnetic tape and ADR (Automated Dialogue Replacement) made lip-sync more precise. Specialized dubbing studios expanded, and demand surged with the rise of imported animation and foreign TV shows.
- Digital Revolution (1990s–2000s): Digital audio workstations (DAWs), nonlinear editing, and time-coding brought greater accuracy and efficiency. By this stage, localization pipelines had matured, with structured script adaptation and quality checks.
- Streaming Era (2010s): Enter Netflix, Disney+, and global streaming. To serve worldwide audiences quickly, dubbing had to become faster, more scalable, and still maintain quality. This era pushed the industry to work smarter than ever.
- AI Era (2020s–Today): Artificial intelligence is reshaping the field. Tools now automate transcription, translation, voice cloning, cutting costs and timelines dramatically. The future is a hybrid model, blending human creativity with AI-driven speed.
The Different Types of Dubbing
Depending on the different content types and budgets, dubbing has generally been divided into three types below:
- Lip-Sync Dubbing: This is the most common style, typically used for feature films and major TV series. Voice actors speak precisely to match the on-screen actors’ lip movements and emotions, making it look as if the dialogue was originally spoken in the new language.
- Phrase-Sync Dubbing: This approach is often used for documentaries and interviews to narrate or summarize. The original audio is briefly audible before the translated voice-over fades in. The goal isn’t to match every lip movement, but rather to keep the translated speech aligned with the overall pacing and length of the original phrases.
- Time-Sync Dubbing: Common in parts of Eastern Europe, this method uses a single narrator who reads all the translated lines over the existing audio, which remains faintly audible in the background. The narration is timed so it fits naturally with the scene’s rhythm.
Below are some newly named dubbing types, usually clarified into the above main types:
- Animation Dubbing: More flexible because animators (or timing edits) can adapt to new phonemes; focus on performance characterization.
- AI Dubbing: Uses automated transcription, translation, speech synthesis, and voice cloning.
- Simulated Real-Time Dubbing: Emerging for events and streaming; low-latency translation plus synthetic or rapid human re-voicing.
What is the Process of Traditional Dubbing
Professional dubbing is a meticulous, multi-step process that requires a team of skilled specialists.
Step 1. Transcribe and Translate
Translating the script of the video dialogue and narration is the first step. During this process, the translated words need to match the character’s lip movements, timing, and emotions. The goal is to make the audience feel natural, relatable, and culturally relevant.
Step 2. Casting Voice Actors
The voice directors pick voice actors whose voices, ages, and personalities fit the characters. Sometimes they audition for several actors or use voice banks to find the perfect voices that fit both the story and audience expectations.
Step 3. Recording
In the studio, actors watch the scene and record their lines, often using timed cues to hit the right moments. Multiple takes are done to get both perfect timing and authentic emotion, for example, one for lip sync accuracy, another for emotional performance, and sometimes extras as backups.
Step 4. Post-production and Mixing
Finally, the recordings are polished. Editors tweak timing, add breaths or reactions, and adjust the sound so it blends naturally with the music and effects. The result is a seamless, immersive audio track that brings the scene to life.
