Free Audio Translator — Translate Audio to English

Translate audio to English — free, private, browser-based

SnipSound's Audio Translator uses OpenAI's open-source Whisper speech-translation model running entirely in your browser via WebAssembly. Upload a Spanish podcast, a Mandarin interview, a French lecture, an Arabic voice memo — Whisper renders it as English text with accurate timestamps. The first time you click Translate, your browser downloads a ~40 MB AI model from our servers; after that, every translation is local.

What it's great for

• English subtitles for foreign-language videos. Drop in a foreign-language clip you've downloaded, get a .srt with English subtitles you can upload to YouTube.
• English transcripts of foreign-language interviews for journalists, researchers, analysts.
• Understanding voice messages you received in a language you don't speak.
• Studying foreign-language audio for language learning — toggle between source-language and English views.
• Privacy-sensitive content — therapy notes, confidential interviews, internal meetings recorded in another language.

What it's not so good for

• Heavy background noise, music behind voice, multiple overlapping speakers.
• Low-resource languages — quality varies widely. Lao, Maori, Yiddish work but rougher than Spanish/Mandarin.
• Idiomatic / culture-specific phrasing — tiny model gives literal translations.
• Files longer than 60 minutes — capped to protect browser RAM.
• Languages outside the 11 supported targets — to-English works for 99 source languages, but translating into another language is limited to the 11 in the Target list (Spanish, French, German, Italian, Portuguese, Dutch, Russian, Mandarin, Japanese, Arabic, Hindi).

How it compares to Cockatoo, Otter, Rev

Cockatoo, Otter, Rev, Trint, Sonix all run larger Whisper variants on their servers. Quality is meaningfully higher — especially on heavy accents, multi-speaker audio, low-resource languages. They charge $10-30/month or $1/minute because GPU servers cost money. SnipSound's wedge: free, no sign-up, files never leave your device. Use this when privacy / cost matters more than maximum accuracy.

Need transcription instead?

Uncheck Translate to English for source-language transcription, or use the dedicated Audio Transcription tool.

Audio translation, one file at a time

Audio translation here means taking a recording of someone speaking a language you do not read, and getting English text back. Drop the file in, the model listens to the speech and writes out the English. It is the same job an interpreter does for a meeting, except it runs on a recording, on your own machine, and costs nothing.

Because the whole thing happens in your browser, the audio never leaves your device. That matters more than usual for this particular job — the files people want translated are often interviews, legal recordings, medical consultations, family voice notes or research material that should not be handed to a third-party server at all.

Translate MP3 and other audio files

An MP3 translator is the most common way people describe this, and MP3 is what most of these files turn out to be — a voice memo, a WhatsApp note, a downloaded interview. You can translate MP3, WAV, M4A, OGG, FLAC and AAC here, and the same works for the audio inside a video file: MP4, MOV, WebM and MKV all work, because the audio track is pulled out first.

There is no file-size cap and no queue. Longer recordings take longer, and the first run downloads the model, but a phone voice note is usually done in well under a minute.

Whether you think of it as translating audio, wanting to translate sound from a clip, or needing to translate a voice recording someone sent you, it is the same job and the same button — the label people use changes, the work does not.

Which languages can it understand?

The model recognises speech in roughly a hundred languages, and the ones it handles best are the widely-recorded ones — Spanish, French, German, Italian, Portuguese, Russian, Arabic, Hindi, Mandarin Chinese, Japanese and Korean among them. Accented speech, background noise, several people talking over each other and low-resource languages are all harder, and accuracy drops accordingly. Treat the output as a solid draft you can read and act on, not as a certified translation.

What this tool cannot do

It translates into English only. If you need English audio turned into Spanish, or Hindi into French, this is not the tool — that is a different job and we would rather say so than waste your upload. The model was trained to translate speech in many languages to English, in one direction.

It also returns text, not speech. There is no dubbed audio track at the end and no cloned voice. If you want spoken English out, take the translated text to the text to speech tool and generate a voiceover from it.

If you want the words in the original language rather than English, that is transcription rather than translation — use audio transcription instead, or the video to text tool for video files.
