Subtitle Translator: One Video, 86 Languages

Subtitle Translator: One Video, 86 Languages Features
EchoWave's subtitle tools are used by creators, educators and global teams worldwide
Subtitles without borders
Your content already travels. Your subtitles should too.
Most views for most creators come from outside their home country, and subtitles are the cheapest translation a video can get. EchoWave transcribes your clip with word-level timing, then translates the caption track with AI that understands context, not word-for-word substitution. Keep the original language alongside the translation as a bilingual track, restyle everything with animated caption presets, and export burned-in video, or SRT/VTT files per language on a paid plan. It builds on the same engine as the caption generator.

What you get
A full translation workflow, not a text box
Transcription, translation, styling and export live in one place, so nothing is copy-pasted between tools.
-
Transcribe First, Translate Second
The ASR engine produces a word-timed transcript of your video, which becomes the source for translation. Fix any word before translating and every language benefits from the correction.
-
AI Translation With Context
Translation runs through a large language model rather than a phrase table, so idioms, technical terms and tone survive the trip. The catalog covers 86 languages, from Spanish and Hindi to Thai, Korean and Arabic.
-
Bilingual Dual-Language Captions
Add the translated track alongside the original instead of replacing it, the format language learners and international events prefer.
-
Timing That Survives Translation
Translated cues stay locked to the speech timing of the original, so captions land when the words are spoken even when the target language runs longer.
-
Script-Aware Rendering
Captions render correctly across writing systems, including Thai, Japanese, Chinese and other scripts where naive tools break words in the wrong places.
-
Style the Translated Track
Translated captions are normal caption tracks: apply any of the 176 animated presets, adjust fonts and colors, and position them per platform.
-
Export Per Language
Burn the translated captions into the video for free with a small badge, or on a paid plan download SRT/VTT files for each language and upload them as closed captions on YouTube and LinkedIn.
-
Bring Your Own SRT
Already have a subtitle file? Upload the SRT into the editor and translate that track directly, no re-transcription needed.

How creators use EchoWave in real projects
A video translator that keeps the original voice
EchoWave works as a video translator for the words on screen, not for the voice. It turns what is said into subtitles in any of 86 languages, so viewers read the translation while they still hear the original speaker. There is no dubbing and no voice replacement. Transcribing and editing captions is free; translation and SRT or VTT downloads are on a paid plan. For a single language pair, start from Spanish to English subtitles or English to Spanish subtitles.
About the EchoWave team
EchoWave is a browser-based video and audio editor built by Lemon Vault LLC since 2018. The people who build the editor write these guides and test every step in the production app before publishing.
Subtitle translator FAQ
How do I translate subtitles in a video?
Upload the video to EchoWave, auto-generate the subtitles, then choose Translate and pick a target language. The caption track is rewritten in the new language while keeping the original speech timing. Export the result as a video with burned-in captions, or download it as an SRT/VTT file on a paid plan. Translation itself is marked as a paid-plan feature in the editor.
How do I translate a video's audio into English?
Transcribe the speech, then translate the subtitles into English. Upload the video, run auto-transcription in the original language, pick English as the target, and the English lines keep the speaker's timing; show the original and the English line together if you want both. EchoWave translates the words on screen; it does not dub the video or replace the voice, so viewers still hear the original audio. For Spanish footage, see Spanish to English subtitles. Translating is a paid-plan feature.
How many languages can I translate subtitles into?
The language catalog covers 86 languages, each listed with its flag and native name, with popular choices surfaced as a grid and the rest searchable. Major world languages, European languages and Asian scripts including Thai, Japanese, Korean and Chinese are all included.
How accurate is the AI subtitle translation?
Translation runs through a large language model that works at sentence level with context, which handles idioms and technical phrasing far better than word-by-word machine translation. As with any automated translation, you can review and edit every translated cue in the editor before you export, and corrections are quick because the timing is already locked.
Can I show two languages at the same time?
Yes. EchoWave supports bilingual captions: the translated track is added alongside the original rather than replacing it, so viewers see both languages together. This is popular for language learning content and international events.
Can I translate an existing SRT file?
Yes. Upload your SRT into the editor and it becomes a normal caption track, which you can then translate to any language in the catalog and re-export as burned-in captions, or as SRT or VTT on a paid plan. Malformed SRT files are tolerated and cleaned up on import.
Does the translation mess up the subtitle timing?
No. Each translated cue inherits the timing of the original speech, so captions stay synced even when the target language is wordier. If a specific cue needs adjusting, you can edit its bounds on the timeline like any other clip.
What is the source language detection?
When you transcribe, the spoken language is detected automatically, and you can override it manually if the detection picks wrong, useful for mixed-language audio or heavy accents. Transcription itself supports the full language range of the underlying speech recognition engine.
Is the subtitle translator free?
You can transcribe and edit captions for free, but translation is marked as a paid-plan feature in the editor, and so is downloading SRT or VTT caption files. Free video exports with burned-in captions include a small watermark and a short end card and are capped at 720p, while paid plans remove them and unlock higher resolutions.
Should I burn in translated captions or upload an SRT?
Burn them in when you want guaranteed styling everywhere, one video file per language with captions that cannot be turned off. Upload SRT/VTT closed captions when a platform supports multiple caption tracks on one video, like YouTube, so a single upload serves every language. EchoWave offers both from the same project, with the SRT/VTT download on paid plans.
