What is video voice dubbing?

Voice dubbing involves replacing the original audio in a video with a translated voiceover in different languages. It can be a complex edit because you must replace the voice audio without affecting the sound, transitions, or music. To overcome this challenge, many customers translate the subtitles or captions of videos instead, which Vimeo incorporates with an embeddable Vimeo player so viewers can select from multiple languages.

Companies looking to add a more immersive experience can rely on AI-powered tools like Vimeo AI translation tools to add translated dubbing in different languages. These tools use voice cloning to create audio that sounds like the person speaking, adding a more cohesive and authentic viewing experience.

Dubbing vs. voiceovers: 3 key differences

The terms dubbing and voiceover are sometimes used interchangeably, but there are differences which distinguish the two.

1. Dubbing replaces voice audio

During the video editing process, content creators use dubbing to replace the actual voice audio with a translated voice file. That way, the original audio isn’t present to confuse the listener. Meanwhile, voiceovers, as their name implies, are placed over the original audio, often at a higher volume to drown out any competing sounds.

2. Dubbing can be lip-synced

Dubbing a video translation involves attempting to match the speed, tone, and delivery of the speaker in the video as closely as possible. That way, their speech still looks natural in a different language. 

A voiceover doesn’t attempt to match speech to lip movements. It’s often used during segments like cutaways or panoramic shots where no characters are on screen.

3. Voiceovers can use anyone’s voice

When you place a voiceover in a video, you can technically use anyone’s voice since usually there aren't characters on screen. For example, David Attenborough’s soothing voiceovers often feature in nature documentaries, but you wouldn’t use them to dub the dialogue of a bubbly college student introducing prospective students to campus.

7 of the best software and apps for video dubbing

With the advent of new AI technologies, several companies are competing to become the best AI dubbing software. The following are seven of the best online tools for dubbing voices in your video content.

1. Vimeo AI video translation

Vimeo’s AI video translation tool with the option to choose English, French, and Korean audio dubbing for a video of a woman speaking into a microphone.

2. HeyGen

HeyGen’s AI avatar creation tool, showing images of AI-generated people speaking to the viewer. The cursor highlights an avatar named “Sandra.”

HeyGen is an ultra-realistic AI avatar generation tool that lets businesses and individuals leverage the power of their voice without needing to be on camera themselves. All users need is a script and they can create, personalize, and localize videos at scale.

HeyGen has free plans available, but also creator, team, and enterprise options. Creator and team packages range from $29 to $39 monthly and allow users to generate an unlimited number of videos. Enterprise plans give businesses access to a dedicated customer service manager and higher-grade security and privacy features. HeyGen is a Vimeo partner helping users generate audio from a video script and more.

3. Rask AI

The homepage for Rask’s AI Video Translator shows an image of people communicating through language barriers.

Rask AI offers several tools that help content creators translate their video content into over 130 languages. Its tools include text-to-speech, subtitles, transcriptions, and audio dubbing, all enhanced by advanced AI technology that handles lip-syncing and voice cloning. 

It requires a monthly subscription, ranging from $50 to $600 monthly, and you have to pay extra to expand your limit of minutes, or to use services like video editing software and developer API. If you have a lot of short videos to translate into different languages, Rask AI might be the right choice for you.

4. Dubverse

The Dubverse homepage begins with the headline, “Voices so real, you won’t know it’s AI.

Dubverse is a more modest tool that offers a tight set of features: AI dubbing, subtitles, and text-to-speech translations. Developers can also integrate the AI into their tech stack to automate translation processes

It’s significantly more affordable than other options, but you must purchase credits to spend on AI tasks, which can quickly add up. If you’re just experimenting with adding AI translations to your videos, it’s a good entry point, but you’ll want to scale up to a more comprehensive tool in the long term.

5. Notta

The Notta homepage showcases an image of their software beneath the headline, “AI Step-by-Step Guide Generator.”

Notta offers free video dubbing software for anyone who wants to translate short videos that are under three minutes long. It’s good for social media content creators who make short-form videos, and it’s an affordable option if you need to upgrade to their Pro subscription. 

Notta is actually an AI doc generator, first and foremost, and it can help you create step-by-step guides in minutes. The audio dubbing features are an added bonus, but they don’t support as many languages as other options on this list (just 15), and the translated audio can sound somewhat robotic, even with voice cloning enabled.

6. Elai

The Elai homepage begins with the headline, “Translate your videos in a single click.”

Elai is a unique option among AI dubbing apps in that it offers not just AI-generated voices and subtitles, but avatars, too. You can select from over 80 different avatars to appear in your video. They’ll speak the lines you give them, whether they’re in English, Spanish, or any of the over 75 different languages Elai supports. If you’re reluctant to appear on camera or if you want your videos to showcase a wide diversity of speakers, Elai might be the choice for you.

7. Maestra AI

The homepage for Maestra’s AI Video Translator offers a box for uploading files.

Maestra offers several AI-enhanced features, from voiceovers to translations. It supports over 125 different languages, voice cloning, and transcriptions. You can even try it for free by uploading a file to their site and previewing the output in any language. 

However, you’ll have to sign up for a subscription to export files or save projects. Like several other AI language-dubbing apps, you must purchase credits to spend on AI-generation tasks.

Enhance your video localization strategy with Vimeo
