The voice is cloned from the speaker, so the dubbed version sounds like the same person speaking another language. You also get the translated text and an SRT file. ## Translate and voice over any video AI video dubbing replaces the spoken audio of a video with a new voice track in another language and leaves the picture untouched. It is not subtitling and not a text translation: the output is audio, with the pacing of the original. Traditional dubbing needs a translator, a voice actor and a sound engineer; here it is one upload and a few minutes. What comes out: - **The dubbed video.** Same picture, same length, new voice track. Compare Original and Dubbed in the player, then download. - **The new audio track on its own.** For editors who mix it themselves. - **The translated text and an SRT file.** The words of the new track with timings, for captions or for checking the translation before you publish. Several speakers each get their own cloned voice and stay distinct; background music and sound effects stay where they were. Two honest limits: text burned into the picture stays in its original language, and lip movement is not adjusted. ## AI voice translator for videos: three steps 1. **Add the video** Paste a YouTube link or upload an MP4, MOV or WebM file. For a file, its length shows before anything starts. 2. **Choose the language** Pick the language you want to hear. The source language is detected automatically. Confirm you have the right to use the video. 3. **Dub, compare, download** Dubbing takes a few minutes, and a share link lets you close the tab and come back. Switch between the original and the dubbed track, then download the video, the audio or the text. Dubbing runs on the audio, not on captions, so it works on videos with no subtitles at all. The most common directions are Spanish to English, Hindi to English and English to French; any supported pair works. ## Free version limits Your first dub is free, no sign-up. Leave your email for one more, then create a free account and pay only for what you use. Free dubs carry a small watermark. Re-opening a result you already have does not count. Free dubbing is sized for short videos: the length and file-size caps are shown next to the upload area, and each dub covers one language. Your dubbed video stays at its own link for a while, so download what you want to keep. ## Voiceover generator that keeps your voice — and opens ads in languages you don't speak Creators dub to publish one video in several languages. Marketers use the same voiceover generator in reverse. A video ad made for Mexico, Brazil or India tells you nothing if you do not speak the language; dubbed into yours, it tells you everything in the length of the clip: the hook, the offer, the objection it closes, with the delivery and the tone intact. A text translation gives you the words and loses the tone, and the tone is usually the part that explains why the ad works. The catch is scale: knowing what works in a market means the ads that have been running there for months, for every brand in the niche, and uploading those one by one is a week of work. In Spytrend that step disappears: video ads from Facebook and TikTok are already collected, and on paid plans any of them can be voiced over in your language in one click. You pick the market and the category, and the ads speak your language. ## Every video ad in any market, voiced in your language Spytrend is an ad intelligence platform for Facebook and TikTok advertising: a full five-year archive of ads, AI-classified into 33 business categories, with every advertiser assembled into a single card — all ads, pages, domains and countries in one place. On paid plans, any video ad in it can be voiced over in another language in one click. ### Two jobs where the language barrier is the whole problem - **Showing a winning ad to the people who sign off the budget.** A client or a team lead who doesn't speak Portuguese won't approve a Brazilian creative from a transcript. Voiced in their language, the ad plays the way it plays in its market — the pace, the tone, the moment the offer lands — and the decision takes one viewing. - **Checking whether a hook survives the language change.** Some openings work because of a pun, a local reference or a rhythm that only exists in the original. Hear the dubbed version before you brief a shoot: if the hook falls flat in your language, it will fall flat for your audience too, and you have saved a production day. ### What the voice-over is attached to On this page the dubbed video stands alone. In Spytrend it sits inside the ad card, so every voiced ad comes with its launch date, its days running and the countries it runs in. One level up is the whole advertiser: all ads, pages, domains and countries in one card, with an ad-spend estimate. ### A market read in three steps 1. **Pick the country and the category** Choose a country and one of 33 business categories, or type a brand or a domain. You get the video ads running in that market. 2. **Voice over the longest-running ads** Sort by run time, open the top ads, press translate and voice over. An ad that has run for months is one that pays for itself, so those are the hooks worth hearing. 3. **Carry the angle across borders** Compare a brand's ads country by country. The angle that runs everywhere is the one to adapt; the one running in a single market is a local test. ### Why the market, not the video One dubbed video tells you what one advertiser said once. A market read needs the ads that stopped as well as the ones running now, with their run time and their spread across countries. A free ad library gives none of that; Spytrend keeps five years of ads, adds 10 million new ones a day and records how long each one ran. ### How to start A free Spytrend account opens the ad library; paid plans add fresh ads and every filter. Search a brand from a market whose language you don't speak and see which of its video ads have run longest. ## FAQ - **How to dub a video into another language?** Add a video you have permission to use, choose the target language and start dubbing. The tool transcribes and translates the speech, generates the new track in a cloned voice and mixes it back into the video. It takes a few minutes; the share link opens the result when it is ready. - **What is AI video dubbing?** AI video dubbing transcribes speech, translates it into a selected language, generates replacement speech and mixes that track onto the original picture with the timing aligned. The picture, the music and the length of the video stay as they were. - **Does the dubbed video keep my own voice?** Yes. The new track is generated in a voice cloned from the speaker in the video, so the dubbed version sounds like the same person speaking another language. With several speakers, each gets their own cloned voice and they stay distinct. - **How long does video dubbing take?** A few minutes for a short video; longer videos take longer. The page shows progress, and the share link means you can leave and come back to the finished result. - **Which languages can I dub into?** The list next to the language field is the whole list, and every language on it gets the same voice cloning and the same output. The source language is detected automatically, so you only choose the target. - **Is the translation accurate enough to publish?** It is machine translation voiced by AI, so check names, numbers and brand terms before publishing; the translated text and the SRT file are there for that. On-screen text and lip movement are not adjusted. - **Do you keep my videos?** Only for a while. Your video and its dub stay at the result link so you can come back to them, then they are removed. Download what you want to keep. If you leave your email, we may write to you about Spytrend. - **How is this different from the voice-over inside Spytrend?** Here you upload one video and get it voiced. In Spytrend the video ads are already collected from Facebook and TikTok, and on paid plans a click voices any of them over in your language, so you pick a country and a category and hear what has been running there longest without uploading anything. ## Pick a market.
