How to add Greek subtitles to a video on iPhone, with the accents right

Published 13 October 2026

Short answer: open Voxcene and import your video. Leave Spoken language on Greek (it’s the default) and tap Create & transcribe. The captions come back timed word by word, set in Greek type that follows Greek rules: no accents on all-caps, accents kept on a capital at the start of a word, a proper final «ς», and no line ending on a stray «και» or «στη».

The rest of this guide covers each step, what “correct Greek” actually means, and how to translate, clean up and export.

Step by step

  1. Start a project. On the Home screen tap Start something new, then Import video (“Pick from your library and caption it”).
  2. Check the language. On New project, Spoken language is set to Greek. If you’re not sure what’s spoken, pick Detect automatically and the app works it out from the audio.
  3. Pick the video. Tap Choose a video, film one with Capture a video, or bring one in from Choose from Files or cloud.
  4. Tap Create & transcribe. You’ll see Uploading → Preparing audio → Transcribing → Building captions → Ready. Then tap Open editor.
  5. Fix any word. In the Captions tab tap a caption, then Edit word, and tap the word to change. The corrected word keeps its timing. If you leave the field empty, the word is deleted.
  6. Choose a look. In the Style tab, All caption styles shows 143 styles. Each lets you change the font, size, colours and Letter case (As spoken, AA, aa, Aa).
  7. Export. Tap Export and choose Burned-in video to save the video with captions to Photos. Or choose Export subtitle files for SRT/VTT to upload to YouTube or Facebook.

What “correct Greek” means, and what Voxcene does about it

Greek has a few typographic rules that captions often break. Voxcene handles each of them:

RuleWrongRight
All-caps text carries no tonosΚΑΛΗΜΈΡΑΚΑΛΗΜΕΡΑ
A capital at the start of a word keeps its tonosΗτανΉταν
A word ends in final sigmaΣασΣας
A line doesn’t end on a short word…που πήγαμε στη / Θεσσαλονίκη…που πήγαμε / στη Θεσσαλονίκη
  • Capitals. Choose AA and the text is uppercased by Greek rules, so the tonos drops. Choose Aa and every word gets a capital first letter that keeps its accent.
  • Line breaks. Articles, prepositions and small words are kept with the word that follows. This covers ο, η, το, στη, στο, σε, με, για, και, να, θα, δεν, που and others.
  • Fonts. Every built-in caption font is checked for complete Greek: all accented letters plus ϊ and ΐ. Your brand’s own font is checked when you upload it. If it can’t set Greek, the app tells you.

Translate the subtitles to English

Want the video in Greek with English subtitles? In the editor, open Language in the captions and tap Translate → English. A Greek project defaults to English as the target, and you can pick any of 60+ languages. Translation uses AI credits: 3 credits per minute of video. Premium includes 600 credits a month. Bilingual, which shows both languages at once, is part of Premium.

The Captions panel in Voxcene showing the Language options Original and English, and a Translate → English button Captions → Language: keep the original, or tap Translate → English.

Remove the «εεε» and «εμ»

On Premium, open AI Studio → Filler Removal. Voxcene lists the hesitations it found («εε», «εεε», «εμ», «μμ», «χμ» and so on) as Safe, Review or Keep, and only the safe ones start ticked. Words that carry meaning («λοιπόν», «δηλαδή», «βασικά», «ουσιαστικά») are never ticked for you. Tap Hear it to check one. Then choose Remove from captions only, or Remove from video and captions to cut them out of the video itself.

The Filler Removal sheet in Voxcene listing a Greek «εεε» marked Safe, with Remove from captions only and Remove from video and captions buttons Filler Removal lists every «εεε» before anything is cut, and you choose captions only or the video too.

Questions

Is it free?

You can try it free on videos up to 60 seconds: 3 minutes of transcription a month, 4 caption styles, and a watermarked 720p export. Basic (€8.99 a month) takes videos up to 15 minutes, gives 120 minutes of transcription a month and all 143 styles, and exports clean 1080p.

Does it work without internet?

Transcription and translation need a connection, because they run on our servers. Once a project is transcribed, you can edit it offline.

Can I get an SRT file instead of burned-in subtitles?

Yes. On the Export screen choose Export subtitle files: SRT and VTT are selected by default, and ASS, TXT and JSON are there too.

Will it delete words like «λοιπόν» or «δηλαδή»?

Not unless you choose to. Filler Removal, part of Premium, finds hesitations like «εεε», «εμ» and «μμ» and proposes them. Words that carry meaning, such as «λοιπόν», «δηλαδή» and «βασικά», are never pre-ticked. Nothing is removed until you press the button.

Is there an Android version?

Not yet. Voxcene is iPhone only for now.
