AI Dubbing vs Traditional Translation: Advantages and Disadvantages

The use of videos allows businesses to easily reach anyone across the globe with any information they want. All sorts of videos, from commercials to product demonstrations to virtual learning sources, have proven to be a powerful way to communicate. However, there are instances where people would not understand the message.

AI dubbing and traditional translation are two methods that should be used to make video content more accessible. AI dubbing uses technology to create a spoken version of the video in a different language. Traditional translation uses human input and consists of making a translation of the script and recording the translated version.

AI Dubbing vs Traditional Translation: The Core Difference

Artificial Intelligence dubbing is a process through which Artificial Intelligence is used to convert the spoken content of a video into other languages. This conversion is done using various tools that may even create synthetic voices resembling that of the original speaker while adjusting the timing in accordance with the video.

AI dubbing begins when speech recognition occurs. The AI identifies the words spoken in the video, translates the speech into the target language, and creates sound in this new language. Some tools also include speaker identification, voice cloning, and automatic subtitle creation. The features will depend on the particular AI used, so when comparing AI dubbing services, ask which of these features are included and where human review happens.

Human dubbing involves people in more stages of the process. The dialogue script for dubbing is written by the translator and may be proofread by the language reviewer. The voice actors lend their voices for the translated dialogues, while the sound engineer and editor complete it by changing the timings or volume, etc. The biggest difference between the types of dubbing is not in the usage of technology or the extent of human involvement in the process. Human dubbing is a way of letting qualified people participate in the process of dubbing and make conscious creative decisions concerning tone, rhythm, humor, and culture.

Advantages of AI Dubbing

AI dubbing helps businesses to produce videos in different types of languages. 

1. Cost-effective production: AI tools offer the advantage of dubbing audio more quickly than traditional processes that require script-writing, voice recording, and editing in a studio. Organizations can get speedy translated versions of product videos, instructional videos, and internal training materials.   
2. Affordable production: Using this, eliminates the need for voice actors and the time spent in studios. This can be helpful for companies with limited finances. However, pricing depends on the chosen solution, language pair, amount of editing needed, and the requirements for review.   
3. Multilingual production support: Some AI dubbing techniques support generating audio files in multiple languages using a single workflow, and that makes it easy to produce content for several segments of markets without having to record audio for each language.
4. Reliable output: By using the same synthetic voice across many voiceovers, a brand can maintain its identity in its recorded form of communications. This can help in the creation of tutorial videos, product updates, etc.
5. More convenient updates: If a certain function has been changed in a product or an instruction has been revised, the team can just change the script, and the audio will be ready. Compared to organizing a new recording session, this approach is much more convenient, especially for newly released materials.
6. Choice of accents and styles: Depending on the platform used for production, people can choose among various voice styles and accents.

Disadvantages of AI Dubbing

AI dubbing helps to render voice so that one can clearly understand what is voiced; however, it is unable to convey emotions similar to those of the human speaker. Knowing the most common AI dubbing translation mistakes helps teams decide which lines need human review.

1. An AI-generated voice does not express emotions as effectively as a natural one does. A machine can do everything in the correct form, but can be incapable of communicating the emotions.
2. There can be cases when a translation is inaccurate due to misinterpretation of unclear speech, difficult terminology etc. Errors in the source transcription can cause further issues in AI translation.
3. Names, local phrases, etc can be pronounced incorrectly by the system/machine. As a result, the audience may feel that the product is not of adequate quality.
4. Cultural differences can be dangerous for the process of translation, as phrases that sound good in one language may sound rude, strange, or awkward in the other language. AI translation applications may miss the proper cultural meaning of the phrases, even if the provided translation seems to be correct. 
5. The synthesized voice won’t be able to copy the inflections and speech patterns of the original speaker.

Advantages of Traditional Translation and Human Dubbing

Services related to human translation and dubbing are significant when it comes to transmitting information in an emotionally meaningful or culturally relevant way, or when conveying exact terminology.

Better understanding of context: Human translators can handle the matter well as they can understand the purpose of the video, the nature of relationships between the speakers, and what the phrase means exactly in the context of the main plot.

Natural emotional delivery: Voice actors are able to select the proper tone, the pace of speech, loudness, and pauses depending on the requirements of a concrete scene.

Cultural adaptation: Human interpreters can notice various jokes, idioms, references, and quotes that may be lost in the target language. They can transform such elements in order to keep the original message and brand intact.

Supervision of voice acting: Producers can choose voice talents according to their age, accent, and speech style. They can also manage the acting process and ask for changes if the results do not meet the demands.

Better creative control: The human-based dubbing teams coordinate the script and sound design. These might be crucial in the audio production of movies, commercials, and videos in cases where the timing or tone is set inaccurately in the beginning.

Human dubbing doesn’t mean 100% accuracy. Errors made during translation, inconsistencies in terminology, and actors’ performances are also possible, and these are the same issues behind most cases of bad dubbing. The quality will depend on the people involved, the guidelines, and the monitoring of the process.

Disadvantages of Traditional Translation and Human Dubbing

1. Higher costs: Production costs are expected to rise due to the requirement of hiring a professional translator, voice actor, sound designer, and project manager. Creating versions for several languages might mean recording in each language separately from scratch.
2. Long deadline: The process of making several videos for languages would require a thorough translation of the script and preliminary recordings first. Thus, all the team members would have to work together.
3. Keeping in mind constant content updates: With regular changes of the educational resources, there will be a necessity to re-record the voices as well. Even minor changes may require a lot of work.
4. Problems with team coordination: There will be a number of people involved in the project, such as translators, voice actors, editors, and so on. Coordinating their work is going to be rather difficult.
5. Difficulties with the dubbing process: The dubbing of the same text by several voice artists can lead to different results of dubbing and make supervision impossible.

Best Use Cases for AI Dubbing, Human Translation, and Hybrid Workflows

Various video content forms require different degrees of attention. The first step in the selection of an appropriate solution is comprehension of what the video needs to convey.

AI audio dubbing works fine for training videos, simple tutorials, video instructions for software products, educational videos that undergo regular changes, and a large number of informational video materials. Production time is shorter in those cases because several linguistic versions of the videos can be created.

Movies, documentaries, advertisement campaigns, narrative films, and materials that contain humor or cultural references are best translated and dubbed by the human. Human dubbing is also necessary in avoiding the dissemination of incorrect information in certain cases. The hybrid approach uses a combination of technological and human intelligence. For example, the first version of the audio can be performed by robots, while linguists are involved in the accuracy control stage. The discussed solution is capable of streamlining the production process without eliminating quality guarantees. Real results after replacing human voiceovers with AI-dubbed audio show where this human review makes the biggest difference.

Which should you choose? Use-case guide
