A free audio translator that turns speech in any language Whisper knows into English text and subtitles, with the recording kept on your device.
Drop a recording in any language: Whisper writes it out on your device, then AI translates the text into English, line by line.
Add your recording
The recording stays on your device: Whisper runs in your browser, and the model downloads once (77 MB). Then AI on our server translates the text into English.
This free audio translator turns speech in any language Whisper knows into English text and subtitles, with a time on every line.
Whisper writes the recording out in its own language, on your device. Then AI translates the text into English, line by line.
Here's how it works, how good it is, and how to get other languages too.
What is an audio translator?
An audio translator turns speech in one language into text in another. This one writes English from any language Whisper knows, and keeps the time of every line.
OpenAI describes Whisper as "a multitasking model that can perform multilingual speech recognition, speech translation, and language identification."
How it translates
Whisper writes what's said in its own language first. Whisper's own translation is rougher: on our Spanish example, whisper-base wrote "the Sorra and the Uvas" for the fox and the grapes.
So the text goes to AI on our server, which reads the lines around each one and translates the meaning. Only the text is sent, never the recording.
English subtitles
SRT and VTT keep every line's time, so they work as English subtitles. Upload either to YouTube, Vimeo or your video editor.
Check names and places before you publish: a translation is only as clear as the recording.
Other languages
Translate to, under the file, takes the transcript into 1 of 30 languages the same way. To switch back, pick the original at the top of the list.
To keep the original language only, use the audio to text converter or Spanish transcription.
On your device or on our server
The page opens on your device. Whisper, OpenAI's speech recognition model, runs in your browser, and the file never leaves it.
For long files, pick On our server. The sound goes in 2-minute pieces to Groq's Whisper and comes back as text in seconds.
| On this device | On our server | |
|---|---|---|
| Privacy | Nothing leaves your device | Sent in pieces, not kept |
| Download | 77 MB once, or 563 MB for Best | None |
| Length | No limit | Up to 30 minutes a file |
| Cost | Free | Free, within a daily limit |
Groq, the company that runs the server's Whisper, says in its data policy that "by default, Groq does not retain customer data for inference requests." We don't keep the sound either.
Standard or Best
Standard is whisper-base, a 77 MB download that runs in any modern browser. On a 2021 MacBook Pro, it wrote a 23-second clip in 5 seconds.
Best is whisper-large-v3-turbo, 563 MB, on browsers with WebGPU. It wrote 100 seconds in 10, and a Spanish clip word for word, after its download.
| Model | Download | Runs on | Best for |
|---|---|---|---|
| Standard | 77 MB | Any modern browser | Quick notes, clear speech |
| Best | 563 MB | Browsers with WebGPU | Names, accents, other languages |
Without WebGPU, Best is whisper-small, 249 MB, which is slower. Each model downloads once, and your browser keeps it.
Files it takes
Anything your browser can read: MP3, M4A, WAV, AAC, FLAC, OGG, Opus, MP4, MOV, WebM and MKV. A video's sound is read, and the picture stays on your screen to play along.
The file is read in parts, so an hour-long recording works on a computer. A phone can take longer on the device, and On our server is quicker there.
Try the example
The example is a 52-second Aesop fable in Spanish, "La zorra y los racimos de uvas," read by Paulino for LibriVox. It's in the public domain.
After you translate
Pull quotes and posts from the English with the asks in step 3. A dubbed voice that sounds like the speaker needs a paid voice clone, which this tool doesn't make.

It's for anyone who needs a recording in another language:
- Spanish transcription – people working with Spanish audio
- Audio to text converter – anyone who wants the original words first
