Translate uploaded audio or video into one of 18 target languages with AI dubbing. Audio mode generates translated speech while aiming to retain the original speaker's vocal characteristics, delivery, and timing. Video mode also attempts to synchronize visible lip movements with the new speech. Preview and download the result in your browser. Quality varies with the source language, pronunciation, background noise, overlapping speakers, and facial visibility.

What Is AI Dubbing?
AI dubbing translates speech in an audio or video file into another language and generates corresponding spoken audio. Instead of producing translated text alone, it creates a version that another-language audience can listen to directly. Echora combines file upload, target-language selection, dubbing, preview, and download in one browser-based workflow.
- Upload one audio or video file for translation and dubbing
- Choose the target language for the new spoken version
- Generate translated audio or a dubbed video online
- Attempt lip sync for visible speakers in video mode
- Preview and download the completed result in your browser
- Create output in 18 currently supported target languages
AI Dubbing vs. Subtitles vs. Text to Speech
These workflows can all help audiences understand content in another language, but they use different inputs and create different outputs. Choose the approach that fits the content you already have and the experience you want viewers to receive.
AI Dubbing
Upload existing audio or video, translate its speech, and generate a new spoken version in another language. Video mode also attempts to match visible lip movements.
Video Subtitles
Keep the original speech and display translated text on screen. This is useful when viewers are comfortable reading, but it does not create a new voice track.
Text to Speech
Create audio from a script you type. It does not require an original media file and does not automatically translate speech already present in a video or recording.
One Online AI Dubbing Tool for Audio and Video
Use video mode as an online AI video translator. Upload a video, choose a target language, and generate translated speech while the workflow attempts to match visible mouth movements. Unlike a subtitle-only video translator, the result is a dubbed video you can preview and download.
Audio mode does more than return a transcript. It translates an uploaded audio file and creates a new spoken version in the selected language, making it useful for podcast segments, interviews, narration, voice instructions, and training recordings.
AI dubbing aims to carry the original speaker's vocal characteristics, delivery, and timing into the target language, helping multilingual versions retain a more consistent speaker identity. Similarity varies by language, accent, and recording conditions, so an exact reproduction is not guaranteed.

No software needs to be installed. Audio uploads support MP3, OGG, WAV, M4A, and AAC files up to 50MB; video uploads support MP4, MOV, and WebM files up to 100MB and 120 seconds.
How to Dub and Translate a Video with AI
Choose a Media Type and Upload a File
Select Audio or Video based on the output you want, then upload one file for translation and dubbing.
- •Audio supports MP3, OGG, WAV, M4A, and AAC files up to 50MB
- •Video supports MP4, MOV, and WebM files up to 100MB and 120 seconds
- •Use source material with clear speech and limited background noise
- •Avoid overlapping speakers when possible
- •For video lip sync, use footage with a visible, unobstructed face
- •Remove long sections of silence when possible
- •Divide videos longer than 120 seconds into shorter clips before uploading
Select the Target Language
Choose the language you want the translated speech to use. The current tool only asks for a target language; there is no separate source-language selector. For example, to translate a video from Spanish to English, upload the Spanish video and select English. The same workflow can be used for the other supported target languages.
Generate, Preview, and Download
Review the media file, target language, and displayed billing unit, then submit the task. When processing is complete, preview the dubbed audio or translated video and download the result. If the first version does not meet your expectations, try using cleaner audio, reducing overlapping speech, removing long silent sections, or selecting footage with a clearer view of the speaker's face.
How to Get Better AI Dubbing Results
Clear source material and a focused review process help produce more useful multilingual versions. These practices cannot guarantee a particular result, but they can improve the quality of the input and make issues easier to catch before publishing.
Use Clear, Single-Speaker Audio
Source media with one clear primary speaker and steady audio usually provides more reliable input than noisy recordings, group conversations, or frequently interrupted speech.
Keep the Speaker's Face Visible
Video lip sync depends on visible mouth movements. Front-facing, well-lit footage with an unobstructed face generally gives the workflow better visual input.
Divide Long Content into Shorter Clips
Video uploads are currently limited to 120 seconds. For lessons, interviews, and product demonstrations, divide longer material by chapter, scene, or speaker so each result is easier to review.
Review Each Language Version Before Publishing
Have a fluent reviewer check names, terminology, tone, cultural context, voice naturalness, and lip-sync quality before you release the localized version.
AI Dubbing Use Cases
Create translated audio and short-form video for audiences in other languages without recording every language version from the beginning.
Short-Form and Talking-Head Videos
Translate social media clips, talking-head videos, product introductions, and short advertisements into other languages while generating new speech and synchronized lip movements. The current video workflow supports clips up to 120 seconds.
Podcasts, Interviews, and Audio Content
Translate podcast segments, interviews, spoken lessons, narration, and voice instructions. Unlike an audio translator that only returns text, this workflow produces dubbed audio that can be previewed and downloaded.
Tutorials, Training, and Product Demonstrations
Create multilingual versions of tutorials, course videos, employee training, and product demonstrations without recording every language version from the beginning. Longer videos can be divided by chapter and processed as separate clips.
International Marketing and Content Testing
Prepare multilingual drafts for advertisements, landing-page videos, brand introductions, and campaign content. Before publishing, have a fluent reviewer check the translation, voice continuity, and lip-sync quality.
