In short: To translate a video to English on Speechma Pro, upload it (MP4, MOV or WEBM, up to 60 MB) or paste a direct video link, set the language spoken in the original, choose English (US) or English (UK) as the target, keep the Automatic voice or pick one yourself, and download the dubbed video as an MP4. It is included in Speechma Pro.

How can I translate a foreign-language video into English?

Upload the video to the AI Dubbing panel, tell Speechma Pro which language is spoken in it, and choose English (US) or English (UK) as the target. Automatic picks a natural native voice, or you can choose a specific voice. The tool translates the speech, voices it in English and returns a new video file that you can download as an MP4 and share.

This is handy far beyond YouTube. An US company can dub a supplier’s training video from Mexico, a family can share a grandparent’s Spanish birthday message with English-speaking cousins, and a teacher can show a Japanese science clip to a class in Ohio without asking students to read subtitles.

Should I choose American or British English?

Your audienceBest choiceWhy
US customers or employeesEnglish (US)Familiar accent, spellings and expressions for American viewers
Canadian audiencesEnglish (US)North American pronunciation is closer to what most Canadians hear daily
UK, IrelandEnglish (UK)Sounds local and matches British terms on screen
Australia, New ZealandEnglish (UK)Closer to the accents viewers there are used to
Global or international mixEnglish (US)The most widely heard accent in online video

Upload requirements: MP4, MOV or WEBM up to 60 MB, or a direct link ending in .mp4, .webm or .mov.

Who uses video translation into English?

English dubbing is often about getting content into an US team or market. Some real-world examples:

  • Creators abroad: a cooking creator in Mexico City or a tech reviewer in Seoul publishing an English version to grow an US audience.
  • Manufacturing and logistics: a plant in Monterrey sharing a process video with a team in Michigan.
  • Nonprofits and churches: mission trip testimonies recorded in Spanish or Portuguese, dubbed for a Sunday service in English.
  • Education: a professor showing a French documentary clip in an intro history class.
  • Family videos: a relative’s message recorded in Hindi, shared with kids who mainly speak English.

Always make sure you have the rights or permission to use the original video, especially when you plan to publish the English version.

How do I check an English dub before publishing?

  • Watch it all the way through once. Listen for names, numbers and product terms.
  • Read the script. Export the audio of the dubbed video and run it through speech to text to see the English words and spot errors quickly.
  • Fix on-screen text. Signs, titles and lower thirds stay in the original language. Add English captions or overlays in your editor.
  • Re-voice a single line. If one sentence needs changing, record a new line with American accent text to speech and drop it in over the original.

Dubbing a lot of videos for your business?

If your team translates training libraries or product videos every week, it may be easier to build voices into your own workflow. The Speechma API gives developers 1,000+ voices with plans from $9/month and an instant key.

Frequently asked questions

Is translating a video to English included in Speechma Pro?

Yes. Speechma Pro’s AI dubbing is included in your plan and does not require an account.

Can I pick between American and British English?

Yes. Choose English (US) or English (UK) as the dub language.

What video formats can I upload?

MP4, MOV or WEBM files up to 60 MB, or a direct link ending in .mp4, .webm or .mov.

Will the English voice match the original speaker?

No. The dub uses a natural native English voice, not a copy of the speaker. You can pick a voice that fits the speaker under More options.

Can I get an English transcript as well?

The dubbing tool gives you the video only. For a transcript, export the audio from the dubbed video as an MP3 and upload it to the speech to text tool.

Can I use the English version on my channel?

Yes, if you own or have rights to the original video. Commercial use of the generated audio is included.
