Use Cases

Every situation covered

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

🎤Keynotes and main stage talks

From a far seat in a keynote hall in Madrid, Mexico City, or Bogotá, the speaker is distant and the Spanish is fast. Point Captio AI toward the nearest PA speaker and read every word of the keynote from any seat.

🔬Academic and research conferences

At an academic conference — a research congress in Barcelona or a scientific meeting in Buenos Aires — presenters speak quickly and pack talks with terminology. Captio AI captions in real time and transcribes for later review.

💼Industry and professional events

Industry events and product launches in Santiago or Monterrey carry content that affects your work. Captio AI captions every speaker so you follow the panel and miss nothing professionally relevant.

📋Workshops and breakout sessions

In a workshop or breakout, several voices contribute in Spanish from around the table. Place Captio AI on the table and follow every contribution, including from the back of the room.

🤝Networking and informal sessions

The most useful conversations often happen over coffee and at the conference dinner. Captio AI works in these noisy, informal settings the same way it does in the main hall.

🌍International and multilingual events

At an international conference, panels switch between Spanish, English, and other languages. Live Translator captions foreign-language sessions in real time so you follow the full programme.

Why Captio AI

Built for the room where you cannot ask anyone to repeat

Live captions from any seat

Point the phone toward the nearest PA output or speaker. Captio AI captions whoever is presenting in real time — from the front row or the back of a large conference hall.

Works without venue infrastructure

No hearing loop, no captioning service, no advance booking required. Captio AI works independently via microphone — whether or not the venue has provided any accessibility infrastructure.

Covers what official captioning does not

Official captioning, where it exists, typically covers the main stage only. Q&A sessions, workshops, breakouts, and networking are usually left uncaptioned. Captio AI covers all of it.

Record and review after

Record any session and upload it to Audio Transcription for a full written record. Use AI Summary to extract key takeaways — useful for dense technical content you want to process at your own pace.

60+ languages

For international conferences, foreign-language keynotes, or multilingual panels. Live Translator captions and translates in real time across 60+ languages with no manual switching between speakers.

Works for networking too

The conversations in hallways and at lunch matter as much as the sessions. Captio AI works in any setting — informal, noisy, unstructured — the same way it works in the main hall.

Spanish

Why Spanish is hard to understand

Speed

  • One of the fastest languages, at podium pace
  • Spanish is among the highest-syllable-rate languages in the world, around 7.8 syllables a second in natural speech. A confident keynote speaker delivers a complex sentence and moves on before a deaf attendee, watching from a distance, can segment it visually. The pace that makes a talk fluent makes it unreadable from the lips.

Syllable-final deletion

  • Caribbean and southern speakers drop word endings
  • In Caribbean and Andalusian Spanish, word-final consonants weaken or disappear — 'las casas' becomes 'lah casah'. A presenter from Havana, San Juan, or Seville produces terms whose endings, which carry number and agreement, simply are not there on the lips.

Dialect variation

  • Spain, Mexico, Argentina on one panel
  • An international Spanish-language conference brings Castilian, Mexican, Rioplatense, and Colombian speakers to the same stage. The seseo–ceceo distinction, Argentine intonation, and Andalusian aspiration create different lip shapes for the same word, so a deaf attendee re-calibrates for every panellist.

Merged rhotics and ll/y

  • Key consonants that are 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 technical term delivered from the podium, the consonants that distinguish it are exactly the ones a lip-reader cannot recover.

Register gap

  • Formal academic Spanish versus the hallway
  • Podium Spanish uses a formal, subordinate-clause-heavy register with long, embedded sentences, quite different from the fast, casual Spanish of the coffee break. A deaf attendee has to lip-read across both — the dense prepared talk and the relaxed networking chat — within the same event.

The Challenge

Hearing loss and professional access across the Spanish-speaking world

In Spain, the National Statistics Institute counts 1,064,000 people who are deaf or have a hearing disability — around 2.3% of the population — while more recent EuroTrak data puts the number living with some hearing loss at roughly one in ten, close to five million people. 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 professional support and workplace accommodation are least developed. These are the professionals filling conference audiences from Madrid to Mexico City.

Spanish-speaking conference culture is vast — the academic congresses of Spain, the technology and industry summits of Mexico, Colombia, Argentina, and Chile — and it runs almost entirely on spoken Spanish delivered over PA systems. National deaf organisations such as Spain's CNSE have long documented access gaps in professional and public settings. Where captioning exists at a conference at all, it covers the main stage; the Q&A, the breakouts, and the networking that drive professional value are left uncaptioned.

Captio AI closes that gap. Point the phone toward the PA and read every Spanish keynote and panel answer from any seat, record a dense session for the full transcript, and follow the conversations over coffee — so a deaf professional at a conference in Madrid or Bogotá gets the same value from the same event as everyone in the room.

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.

People love Captio AI

"Spanish keynotes come fast and the academic register is dense. From the back of the hall I used to lose the thread completely. Captio AI captioned the talk from my seat and I recorded it for the transcript. I followed the whole argument for once."

Hard of hearing, Madrid — academic researcher

"The panel had a Spaniard, an Argentine, and a Colombian, all different on the lips. Captio AI captioned every one of them without me adjusting. I read the whole discussion instead of catching only the speaker whose accent I knew."

Deaf, Mexico City — industry conference attendee

"The Q&A after the launch was the part I needed most and the part I always missed. Captio AI captioned every answer as the mic went around the room. I left knowing exactly what was changing in the product, not guessing."

"Networking over coffee is where the real conversations happen, and it used to be where I checked out. Captio AI captioned the informal chats at the reception so I could actually take part. That is where I met my first investor."
