Use Cases

Every situation covered

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

🩺GP and primary care visits

GP and primary care visits at medical centres across Spanish-speaking Latin America and Spain, where the doctor covers the complaint, diagnosis, and prescription in a brief consultation. Captio AI captions everything in real time.

🔬Specialist consultations

Specialist appointments — cardiologist, neurologist, endocrinologist — in Spanish, where clinical vocabulary is dense. Captio AI captions every term as the specialist delivers it.

💊Pharmacy conversations

Pharmacy conversations in Spanish where the farmacéutico explains dosage, side effects, and interactions quickly. Captio AI captions the instructions so you leave the counter understanding everything.

🦷Dental appointments

Dental visits in Spanish where the dentist explains the treatment plan and names the procedure in medical Spanish. Captio AI captures the explanation and the clinical terms.

🧠Mental health sessions

Mental health consultations in Spanish — increasingly accessible in major Latin American cities — where accurate understanding of the session matters. Captio AI captions the clinician in real time.

🚑Emergency and urgent care

Emergency room visits at public hospitals in Spanish-speaking countries where triage staff speak fast. Captio AI captions the key instructions in the moments when they matter most.

Why Captio AI

Built for the conversations where every word matters

Captions as the doctor speaks

Words appear on screen while the doctor is still talking. You read the diagnosis, drug name, or follow-up instruction at the same moment it is said — not after they have moved on.

Medical terminology handled accurately

Drug names, procedure names, clinical terms. Captio AI handles the vocabulary of a real consultation — not just everyday speech.

Review the appointment after

Record the consultation and upload it to Audio Transcription. Get a full written record of everything said — instructions, dosages, referrals — to review at home and share with a carer if needed.

Works in any clinical setting

Consultation rooms, hospital wards, A&E, dental chairs, pharmacy counters. Place the phone near the speaker and Captio AI captions whoever is talking.

Any language

For foreign-language doctors, specialists abroad, or appointments through an interpreter. Live Translator captions and translates in real time so you follow your diagnosis in the language you understand best.

100% private

Medical conversations are among the most sensitive there are. Captio AI processes audio in real time and discards it immediately. Nothing is recorded, stored, or shared.

Spanish

Why Spanish is hard to understand

Speed of clinical Spanish

  • Spanish doctors in Latin America speak at some of the fastest rates in any language
  • Spanish is one of the fastest spoken languages by syllable rate, and Latin American varieties — particularly Caribbean, Colombian, and Rioplatense Spanish — rank among the fastest. In a Buenos Aires or Bogotá consultation room, a doctor's clinical delivery can exceed 8 syllables per second. A deaf patient has very little processing time between clinical terms before the next phrase arrives.

/s/ aspiration in diagnoses

  • Coastal Spanish drops /s/ from the surface form of drug names and dosage instructions
  • In Caribbean Spanish, Chilean coastal speech, and Andalusian Spanish, /s/ before another consonant is aspirated or dropped entirely. 'Dos pastillas' becomes 'doh pa'tillah.' Dosage instructions, drug names, and clinical counts built around this consonant lose a key phonological anchor for a deaf patient trying to identify the drug or dose.

Spain–Latin America divergence

  • A deaf patient trained on Castilian Spanish encounters a different phonology in Latin American clinics
  • Spanish phonology differs substantially between Spain and Latin America, and across Latin American varieties. Castilian features, seseo, voseo, and yeísmo variations all produce different surface forms for the same medical vocabulary. A deaf patient from one Spanish-speaking context navigating healthcare in another faces a phonological recalibration in a setting where no clinical information should be missed.

English drug names in Spanish

  • Prescriptions across Latin America use English brand names embedded in Spanish clinical speech
  • Specialist consultations across Latin America increasingly name drugs by their English trade names, pronounced with Spanish phonology. Ibuprofen, metformin, atorvastatin — spoken in Spanish rhythm and vowels — are phonologically dense. A deaf patient tracking Spanish loses the thread when the specific drug arrives in its English form.

Latin American medical register

  • Clinical Spanish uses Latinized vocabulary at speed, far from everyday speech
  • Medical Spanish draws heavily on Latin and Greek roots: hipertensión arterial, miocardiopatía, taquiarritmia, insuficiencia renal. These terms are phonologically long and arrive in a rapid clinical delivery. A deaf patient who knows the colloquial equivalent — presión alta, problema del corazón — will not recognize the formal clinical term spoken at consultation speed.

The Challenge

Over 217 million people with hearing loss in Latin America. Healthcare built around the assumption they can hear.

Latin America has approximately 217 million people with some degree of hearing loss according to WHO projections, with about 32 million living with moderate to severe hearing impairment — roughly 9% of the global moderate-to-severe hearing loss population. Across the region, barriers to healthcare for deaf and hard of hearing people follow a consistent pattern: cost, geographic distance, and a healthcare system that has not systematically designed for patients who cannot hear the clinician. A study of deaf patients in the Dominican Republic published in BMC Global and Public Health (2025) found that the social determinants driving exclusion from healthcare — poverty, rural distance, lack of sign language interpreters, and clinicians with no training in deaf communication — are structural and mutually reinforcing.

In Spain, Lengua de Signos Española (LSE) has been formally recognised since 2007, but the legal right to an interpreter in healthcare settings is not consistently implemented. In Mexico, LSM (Lengua de Señas Mexicana) has constitutional recognition but no enforceable provision for medical interpreter access. Across most of Latin America, sign language recognition in law has not translated into interpreter access in clinical practice. Deaf patients routinely attend appointments without language support, relying on written notes, family members, or approximation when the clinical vocabulary exceeds their ability to follow.

Research on Spanish-speaking hard of hearing patients in the United States found compounded barriers: the healthcare system assumed they could hear, and often also assumed they could read English clinical materials. A study published in Health Communication (2025) found that Spanish-speaking hard of hearing patients faced the convergence of language and hearing access barriers simultaneously in clinical settings. Captio AI captions Spanish speech in real time across dialects and registers — from fast Caribbean Spanish at a community clinic to formal Castilian at a Madrid hospital — so a deaf patient can follow their own appointment without a hearing companion.
