Guide · AI vs agency
Traditional agencies, self-serve AI tools and AI-powered agencies each solve a different problem. This guide compares them on the criteria that matter for business videos, so you can pick the right option for each project.
Choose a traditional agency for scripted productions that need casting, a recording studio and a dubbing director, such as films or TV advertising. Choose a self-serve AI tool when you translate a few videos and your team has time to check each one. Choose an AI-powered agency when you need to translate many videos into several languages, with human review and your speakers' own voices, without running production yourself. That last option is how VoiceCheap works.
Start from the type of content and the resources your team has, not from the technology.
Scripted content performed by actors benefits from a traditional agency: casting, a dubbing director and studio recording give full creative control, at the cost of longer timelines.
For a few short videos, a self-serve AI tool is usually enough, provided someone on your team speaks the target language and can check the result.
Dozens or hundreds of videos need a repeatable workflow, consistent terminology and batch delivery: the core use case for an AI-powered agency.
AI produces languages in parallel, so adding a language does not add weeks. Traditional dubbing books new voice actors for every language.
When the face and voice of a founder, trainer or expert carry the message, voice cloning keeps them recognizable in the translated version, with their consent.
Medical, pharmaceutical or compliance videos need people to review the transcript and the translation before audio is produced, whatever the technology.
How the three ways companies translate videos today compare on the points that decide a project.

A traditional agency splits the job between specialists. A translator adapts the script, a casting team selects one voice actor per speaker and language, a dubbing director records each line in a studio, and a sound engineer mixes the new voice track with the original music and effects. The result can be excellent, especially for fiction and advertising, but every step is manual. Timelines are usually counted in weeks, and each extra language repeats the whole chain.
AI automates the steps that used to require a studio. Speech recognition produces the transcript, machine translation drafts the script, and voice synthesis generates the new audio, either with a library voice or with a clone of the original speaker. Separating the voice from the background keeps the original music and ambience. Automated production is measured in minutes or hours rather than weeks, and adding a language no longer means booking new actors. What AI does not decide on its own is whether a term is right for your brand or your industry.
The errors that hurt business videos are rarely grammar errors: a product name transcribed wrong, a technical term translated literally, an acronym read letter by letter, a sentence that sounds rushed because the translation is longer than the original. An AI-powered agency places people where these errors happen: your team approves the transcript and the translation before any audio is produced, and a reviewer checks every final file. You keep the speed of AI with the accountability of an agency.
