Use Cases

Every situation covered

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

📺Live TV — news, sport, events

RTVE and other broadcasters run live news and sport that pre-generated subtitles lag behind. Point Captio AI at your TV and read the Spanish as it is spoken, not several seconds behind the presenter.

🎬Streaming content

Netflix, Movistar+, and other platforms vary in subtitle quality — and generic subtitles are not the same as captions built for deaf viewers. Captio AI works as a consistent fallback for any Spanish show or film.

📱YouTube and social media

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

🌍Foreign-language content

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

🎭Cinema

Not every cinema showing has open captions. Hold Captio AI near the audio and read real-time Spanish captions of the dialogue discreetly from your seat.

🎧Podcasts and audio content

Most Spanish 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.

Spanish

Why Spanish is hard to understand

Speed

  • One of the fastest languages, at broadcast pace
  • Spanish is among the highest-syllable-rate languages in the world. A news anchor or a telenovela character delivers a line and moves on before a deaf viewer, watching a face across the room, can segment it — and on screen the pace never slows for you.

Syllable-final deletion

  • Caribbean and Andalusian speech drops word endings
  • In Caribbean and southern Spanish, word-final consonants weaken or disappear — 'las casas' becomes 'lah casah'. A deaf viewer watching a Cuban series or an Andalusian presenter meets words whose endings, carrying number and agreement, simply are not there on the lips.

Dialect variation across screens

  • Spain, Mexico, Argentina — every accent streams
  • Spanish-language film and TV span Castilian, Mexican, Rioplatense, and Colombian speech. The seseo–ceceo distinction, Argentine intonation, and Andalusian aspiration create different lip shapes for the same word, so a deaf viewer re-calibrates with every new show or film.

Merged rhotics and ll/y

  • Key consonants invisible or identical
  • The tapped and rolled r of Spanish, and the yeísmo merger of ll and y, produce sounds that are either invisible on the lips or identical to one another. In a fast scene, the consonants that distinguish a name or a place are exactly the ones a viewer cannot recover.

Dubbing and voiceover

  • Foreign content dubbed into Spanish never matches the lips
  • Much foreign film and TV is dubbed into Spanish, so the words a viewer hears do not match the lips on screen at all. For a deaf viewer relying on lip-reading, dubbed content is impossible — the mouth is speaking a different language from the soundtrack.

The Challenge

Spain subtitles most of its television — but not in the way deaf viewers need

In Spain, the National Statistics Institute counts 1,064,000 people who are deaf or have a hearing disability, and across Latin America the World Health Organization estimates that the large majority of people with disabling hearing loss live in low- and middle-income countries where media accessibility is least developed. Spain's audiovisual law requires 90% of public-channel and 75% of open-channel programming to be subtitled, and digital terrestrial television reached over 83% subtitled programming in 2020.

But volume is not the same as accessibility. As Spanish deaf organisations point out, generic subtitles in a language are not the same as subtitles built for deaf people — which mark who is speaking and describe the sounds and music essential to following a scene. And the percentages cover regulated broadcast: live content still lags, streaming and social video vary wildly, and foreign film and TV dubbed into Spanish leave a deaf lip-reader with a mouth that does not match the soundtrack at all.

Captio AI does not depend on the broadcaster or the platform. Point the phone at any screen — a live RTVE news bulletin, a Netflix series, a dubbed foreign film — and read Spanish captions in real time, verbatim, whether or not that content was ever captioned for deaf viewers.

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.
