SHORT ANSWER
Dubbing vs voice-over vs subtitles: these are the main ways to make a video work in another language. Lip-sync dubbing, semi-dubbing, voice-over and subtitles differ in what the viewer hears, how much work they need and what they cost. The right choice depends on your content, your audience and your budget.
What is lip-sync dubbing?
Lip-sync dubbing replaces the original dialogue with a new language version that matches the actors’ lip movements. Viewers hear only the new voices, so the content feels native.
Every character gets their own voice actor. A writer adapts the script so the new lines fit the timing, the breath and the mouth movements on screen. The sound is then mixed so it is ready for broadcast or streaming.
Lip-sync dubbing is the standard choice for scripted content: films, series and animation. It is also important for kids and family content, because young viewers cannot read subtitles. It needs the most work of all four options, so it has the highest cost.

What is semi-dubbing?
Semi-dubbing replaces only the dialogue that needs localizing and keeps the original ambience, music and sound effects. It is a lighter form of dubbing.
The new voices are matched to the timing of the original speech, but not frame by frame to the lips. The cast is smaller, usually between 2 and 10 or more voices, depending on the content. This makes semi-dubbing faster and more affordable than full lip-sync dubbing.
Semi-dubbing works well for documentaries, factual programmes, reality and lifestyle shows, e-learning, and distribution catalogues with many titles.
What is voice-over?
Voice-over adds a narrator’s voice in the new language. The original audio often stays audible underneath, at a lower volume.
Usually one narrator reads the text. There is no need to match lip movements. This makes voice-over the simplest voice option and a good fit for business content.
Typical uses are product videos, explainers, training, internal company videos, brand films and documentaries.

What are subtitles?
Subtitles turn spoken dialogue into timed text on screen. Viewers keep the original voices and read the translation.
A linguist translates the dialogue. The text is then timed to the video and checked for reading speed, so viewers have enough time to read each line. Subtitles also work when a video plays on mute or in a noisy place.
Subtitles for the deaf and hard of hearing (SDH) are a different service. They also describe sounds, music and who is speaking. Standard subtitles assume that the viewer can hear and only needs a translation.

Which one should you choose?
When you compare dubbing vs voice-over vs subtitles, start with your content type and your audience. Then check your budget and your deadline.
- You release a film, a series or animation: choose lip-sync dubbing. Viewers of scripted content expect voices that match the actors.
- You distribute documentaries, factual or reality content at scale: choose semi-dubbing. You keep a natural sound with a smaller cast and a lower cost.
- You make corporate, product or training videos: choose voice-over. It is fast, clear and simple to update.
- You need many languages fast, or your video plays on mute: choose subtitles.
- You need to make content accessible: add SDH subtitles or audio description.
Can you combine them?
Yes. Many releases combine dubbing and subtitling. A series can have a dubbed version and subtitles in several languages, so viewers can choose. A training video can have voice-over in the main markets and subtitles for the others. Combining options helps you balance reach and budget.

FAQ
Is dubbing more expensive than subtitles?
Yes, in most projects. Dubbing needs script adaptation, voice actors, studio recording and mixing. Subtitles need translation, timing and quality checks, with no recording.
What is the difference between dubbing and voice-over?
Dubbing fully replaces the original dialogue, and in lip-sync dubbing the new voices match the actors’ lips. Voice-over adds a narrator over the original sound and does not match the lips.
What is the difference between subtitles and SDH?
Subtitles translate the dialogue for viewers who can hear. SDH subtitles also describe sounds, music and speakers for deaf and hard-of-hearing viewers.
Can I order several languages at the same time?
Yes. We coordinate several languages in parallel, with the same terminology across all versions and aligned delivery dates.
