Use Cases

Every situation covered

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

📺Live TV — news, sport, events

Live TV in Estonian moves fast — an ERR news bulletin, a basketball game, a Song Festival broadcast. Point Captio AI at the screen and read the commentary and reporting in real time as it happens.

🎬Streaming content

Streaming catalogues carry Estonian dubs and originals, but deaf-accessible captions are inconsistent. Captio AI captions a series or film from the audio, so you follow the dialogue whether or not the platform provides subtitles.

📱YouTube and social media

Estonian YouTube and social clips — creators from Tallinn, Tartu, and Narva — rarely carry reliable captions. Point Captio AI at the speaker and read every word.

🌍Foreign-language content

Foreign films reach Estonian screens subtitled or voiced-over. Captio AI captions the Estonian audio track in real time, so you can follow the dialogue directly rather than racing a single narrator's voice.

🎭Cinema

In a Tallinn cinema showing an Estonian film, hold your phone toward the audio and read the dialogue as the scene plays.

🎧Podcasts and audio content

Estonian podcasts and radio — news, history, culture — arrive as audio only. Upload a recording to Captio AI and read the full conversation as text.

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.

Estonian

Why Estonian is hard to understand

Three lengths

  • Short, long, and overlong — all invisible
  • Estonian has a rare three-way length contrast: a sound can be short, long, or overlong, and the difference alone changes a word's meaning. Length is pure timing in the voice, so all three produce the same lip shape and a deaf viewer cannot tell them apart on screen.

Nine vowels

  • Fine vowel distinctions the mouth blurs
  • Estonian has nine vowels, including the back unrounded õ that has no near equivalent in most languages. Several of them sit close together in mouth position, so a deaf viewer watching a presenter cannot see which of the similar vowels was spoken.

Palatalization

  • Softened consonants formed out of sight
  • Estonian palatalizes certain consonants with a raise of the tongue toward the palate, and the softening can distinguish words. It happens inside the mouth, invisible from the front, so a deaf viewer following a film gets no cue for it.

Long word forms

  • Grammar stacked onto the ends of words
  • Estonian builds meaning by stacking case endings and suffixes onto a word, so a single form can carry what English needs several words for. Those endings pile up at the tail where lip-reading is weakest, and in fast speech they reduce, so a deaf viewer loses the grammar of a sentence.

South Estonian gap

  • Võro and the south sound different
  • South Estonian varieties such as Võro differ from standard northern Estonian in vowels and vocabulary. When a programme features a southern speaker, a deaf viewer used to the Tallinn standard meets an unfamiliar sound pattern.

The Challenge

The scale of the challenge

Around one in ten people in Estonia live with hearing loss — surveys put the figure near 11 percent, roughly 140,000 people — in a country of about 1.3 million where nearly a fifth of the population is over 65. That is a substantial audience whose access to television depends on what they can read rather than what they can hear.

Estonia has no legal requirement to make broadcast media accessible; the public broadcaster is only encouraged to do so. In practice ERR has moved forward on its own, rolling out automated subtitles from autumn 2023 for its in-house Estonian-language programmes on ETV and ETV2, using speech-recognition technology developed in Estonia. But that leaves the commercial channels, streaming, and the foreign content that fills the schedules with little or nothing built for deaf viewers.

The result is a viewer increasingly served on the public channels and shut out elsewhere — on the dramas, sport, and foreign films that make up most of the screen. Captio AI closes that gap: point the phone at any screen — an ERR bulletin, a streaming series, a voiced-over foreign film — and read Estonian captions in real time from the audio, whatever the channel and whether or not the content was 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.
