How it works

How do you translate an Indonesian recording into English?

To translate Indonesian audio to English, drop the recording on this page. It is transcribed as Indonesian in short pieces, then each line is translated into English with its time. Read the English transcript, and switch to Original when you want the Indonesian wording.

  1. 1

    Add the recording

    A WhatsApp voice note, a Zoom recording, an interview or a lecture, as MP3, M4A, WAV or OGG.

  2. 2

    Indonesian, then English

    Written down in Indonesian, then translated, for the first 30 minutes of each file.

  3. 3

    Read or save

    Copy the English or download text or Word; the Indonesian transcript saves separately.

Why does the English sometimes choose a different tense?

Because Indonesian verbs don’t mark tense. “Bus itu menuju ke Six Flags…” says only that the bus heads there; our test English chose “is heading”, where the human translation says “was headed”. Words like sudah, akan or tadi settle it; without them, check the recording.

How does the English decide between he and she?

From the conversation around it, because dia means either. “Baru-baru ini dia kalah melawan Raonic” came back as “Recently he lost to Raonic”, which matched the original. When a line could be about a woman, play that moment back.

That’s also why the transcript is translated in batches of lines rather than one sentence at a time: the lines around a dia usually say who it is.

How does Indonesian speech read in English?

Plain and close to what was said. In our test, speech in Indonesian came out strong in English, and sentences crossed over nearly word for word, with times and event names put the English way.

Tepat pukul 08.46 pagi, seluruh kota hening…
EnglishAt exactly 8:46 a.m., the whole city fell silent…
Baru-baru ini dia kalah melawan Raonic di Brisbane Terbuka.
EnglishRecently he lost to Raonic at the Brisbane Open.
Piquet Jr. dipecat setelah Grand Prix Hongaria 2009.
EnglishPiquet Jr. was dismissed after the 2009 Hungarian Grand Prix.

What should you check in the English transcript?

English words said in passing, names and figures. The Indonesian is transcribed cleanly, but an English term can be heard as an Indonesian word first (“T-Rex” once came back as “tirai”), and a misheard word is translated as misheard.

Do your meetings also happen in English?

NoteOwl on a Mac understands 34 languages, English among them though not Indonesian, and transcribes meetings and recordings with unlimited transcription, labelling speakers and keeping them searchable. For an Indonesian transcript without translation, use Indonesian audio to text.

FAQ

Questions about translating Indonesian audio into English

Is the Indonesian to English audio translator free?

Yes. 3 recordings a day, the first 30 minutes of each, with no account; the English, the Indonesian transcript and every download are included.

Can I translate a WhatsApp voice note from Indonesia?

Yes. Export the note from the chat to your phone or computer (it is usually an .opus or .ogg file) and add it here; a short one is back in English within seconds.

What if the speakers mix in English?

This page treats the whole recording as Indonesian. For one that switches between the two at length, use the main audio translator with the spoken language on Detect automatically.

Does it work for Malay recordings?

Use the Malay to English page for speech from Malaysia, Brunei or Singapore: it transcribes in Malaysian spelling before translating.

Are the speakers labelled?

No. The English transcript has words and times only. NoteOwl on a Mac names each speaker in the transcripts it makes.

Is my recording uploaded or kept?

Your browser keeps the file. Short pieces of the sound go to a cloud AI transcription service and the Indonesian text to a cloud AI translation service; both discard what they get. NoteOwl stores no audio and no text.
