Use Cases

Every situation covered

Designed for the real moments that matter — not just quiet controlled environments.

📺Live TV — news, sport, events

ERT and the commercial channels run live news that pre-generated captions can lag behind. Point Captio AI at your TV and read the Greek as it is spoken, not several seconds behind the anchor.

🎬Streaming content

ERTFLIX, Netflix, and other platforms vary in subtitle quality — only selected ERTFLIX programmes carry deaf-specific captions. Captio AI works as a consistent fallback for any Greek show or film.

📱YouTube and social media

YouTube auto-captions for Greek are often inaccurate and most social video has none. Point Captio AI at your phone and read accurate Greek captions for any clip.

🌍Foreign-language content

A foreign film, a foreign documentary, a non-Greek channel. Live Translator captions and translates in real time so anything becomes watchable in Greek as it plays.

🎭Cinema

Not every cinema showing is captioned. Hold Captio AI near the audio and read real-time Greek captions of the dialogue discreetly from your seat.

🎧Podcasts and audio content

Most Greek podcasts have no transcript. Hold Captio AI near the audio or upload a recording, and read the whole episode in writing.

Why Captio AI

Built for the content that subtitles fail

Captions any content in real time

Point the phone toward any speaker — TV, laptop, tablet, cinema screen. Captio AI captions whatever is playing, regardless of whether that platform provides subtitles.

Faster than built-in subtitles for live content

Pre-generated subtitles lag behind live TV by several seconds. Captio AI captions in real time — so you read what is being said as it is being said.

Works on any screen or device

No integration required. Point the phone toward the audio source — the same approach works for a large TV, a laptop screen, a cinema, or a phone held at arm's length.

Any language, translated in real time

For foreign-language content, switch to Live Translator. It translates as content plays — so a French film, a German documentary, or a Japanese series all become watchable.

No subtitle file needed

Captio AI captions from the audio directly. No subtitle file, no platform support, no creator requirement. If audio plays, Captio AI can caption it.

More accurate than auto-generated captions

The industry average for AI-generated subtitles is a 10–15% word error rate — roughly 1 in 10 words wrong (3Play Media). Captio AI is built for accuracy in real-world audio conditions.

Greek

Why Greek is hard to understand

Dental fricatives

  • The θ and δ sounds with almost no visible movement
  • Greek relies on θ (as in 'thin') and δ (as in 'this'), made with the tongue between the teeth and producing very little visible lip movement. On a TV drama or a news read a deaf viewer misses exactly the sounds that carry the meaning of a word.

Velar fricatives

  • The χ and γ sounds made at the back of the mouth
  • Greek has the fricatives χ and γ, produced far back in the mouth with no lip cue. On screen these give a lip-reader nothing to work with, yet they distinguish common words.

Mobile stress

  • Stress that moves and changes meaning
  • Modern Greek has variable, meaning-bearing stress that moves between forms of a word. A deaf viewer trying to anchor a word by its stressed syllable finds the anchor shifts as the speaker inflects it, with the stress carried in pitch, not on the lips.

Cypriot dialect on screen

  • Mainland and Cypriot Greek differ
  • Greek-language film and TV span mainland and Cypriot Greek, and Cypriot has consonant gemination and unique diphthongs the mainland lacks. A deaf viewer calibrated to Athenian Greek meets different shapes on a Cypriot production.

Greek–English code-switching

  • English dropped into Greek content
  • Greek TV, film, and online content drop English terms into Greek sentences. A deaf viewer meets English phonology on the key word, then returns to Greek, with no visual warning and no lip to read after a cut.

The Challenge

Greek captioning for deaf viewers reaches only selected programmes

Greece gathers comparatively little national data on hearing loss, and researchers have found that deaf and hard of hearing Greeks are systematically left out of health policy, with measurably poorer health-related quality of life than the general population. Against a European backdrop in which around one in five people has some hearing loss, a substantial audience depends on captions to follow Greek media.

Provision is narrow. Greece has offered subtitling for the deaf and hard of hearing only since 2006, historically through a single source and requiring special equipment, and today the public broadcaster's streaming platform marks only selected programmes with deaf-specific captions, alongside a sign-language news channel. Live news lags, commercial and streaming subtitle quality varies, and social and short-video content is largely uncaptioned — while the dental and velar fricatives that make Greek hard to lip-read leave a deaf viewer stranded wherever a caption is missing.

Captio AI does not depend on the broadcaster or the platform. Point the phone at any screen — a live ERT bulletin, an ERTFLIX programme with no captions, a YouTube clip — and read Greek captions in real time from the audio, whether or not that content was ever captioned.

Privacy

What you hear stays with you.

Gone the moment it ends

Captio AI processes your audio in real time and discards it immediately. Nothing is recorded. Nothing is kept.

Not a product

Your conversations are not something Captio AI sells, shares, or monetizes — to anyone, for any reason.

Not used to train anything

What you say in a doctor's appointment or a job interview never ends up in a training dataset. Not ours. Not anyone else's.
