How to translate audio online, the right way
To translate audio accurately, transcribe it first and then translate the finished transcript — not phrase by phrase. hearlog does exactly this: it converts speech to an editable transcript with Google Gemini AI, then translates the whole transcript in one click.
Real-time phrase translators are built for short exchanges at a counter or on a call. They struggle with a 40-minute lecture, a customer interview or a family voice message, because meaning in long-form speech depends on context that a phrase-by-phrase pass throws away. Transcribing first captures the full context, so the translation reads like something a person would actually write.
Keeping the original transcript beside the translation matters too. A journalist can quote the source and publish the translation; a student can study the English while checking the original wording; a researcher keeps both for the record. In hearlog the pair lives in one saved note, so it never gets separated — and you can re-translate the same recording into another language any time.
hearlog is built by USD Vision AI and powered by Google Gemini AI. It runs entirely in the browser — no app download, works offline while recording, and produces an AI summary in five styles alongside every translation.

Audio translator — frequently asked questions
Everything you need to know before you translate your first file
What is a free audio translator?
A free audio translator converts spoken audio into text in another language at no cost. hearlog transcribes your recording or uploaded file with Google Gemini AI, then translates the transcript into English or any of 50+ languages — keeping both the original and the translation together in one note.
How do I translate an audio file for free?
Open hearlog, upload an MP3, WAV or M4A file (or record live), let it transcribe, then click Translate and pick your target language. You get the original transcript and the translation side by side, exportable as PDF or Word. No credit card and no per-minute billing.
Can I translate audio to English?
Yes. hearlog translates audio to English from 50+ source languages, including Hindi, Telugu, Tamil, Bengali, Spanish and Arabic. Because it transcribes the audio first and then translates that transcript, long recordings like interviews and meetings translate far more accurately than phrase-by-phrase tools.
What audio formats can I translate?
hearlog accepts MP3, M4A, WAV, OPUS, OGG and FLAC — including WhatsApp voice notes and phone recordings. You can also record directly in the browser. There is no app to download; it runs on any modern phone or laptop browser.
Is the audio translation actually free?
Yes. Transcription and translation are both free on hearlog — 200 minutes free every month — unlike tools that charge per minute or lock translation behind a paid plan. A free account takes about 30 seconds to create, and there is no credit card required.
Which Indian languages can hearlog translate from audio?
hearlog handles Hindi, Telugu, Tamil, Bengali, Kannada, Malayalam, Marathi, Gujarati, Punjabi, Odia and more. It also understands code-switching such as Hinglish, so mixed Hindi-English speech is transcribed and translated the way people actually talk.
How accurate is AI audio translation?
hearlog is powered by Google Gemini AI, the same model family behind Google Translate. Accuracy depends on audio clarity and accent, but transcribing first and translating the full transcript gives cleaner results than real-time phrase translators for long-form audio.
Can I translate long recordings like meetings and lectures?
Yes. There are no time limits — hour-long lectures, interviews and meetings are segmented and processed automatically, then translated in one click. You also get an AI summary and action items, so a long recording becomes a short, shareable, translated brief.
