Use Cases

Every situation covered

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

👨‍👩‍👧Family conversations

A Danish family dinner where grandparents speak Copenhagen standard, parents code-switch into English on some words, and teenagers use youth slang that bears little resemblance to textbook Danish. Captio AI follows every voice.

💼As a hearing colleague

Danish office culture blends formal presentations with relaxed floor debate. Captio AI lets a deaf colleague follow the full conversation — including the informal asides in workplace Danish that hearing colleagues absorb without noticing.

❤️Partners and relationships

A hearing partner who grew up speaking Jutlandic or Funen Danish can speak at their natural pace. Captio AI captions their speech in real time, so home conversation does not depend on writing notes or speaking slowly.

🏠Living together

Spontaneous questions from the kitchen, instructions about household tasks, morning conversation before work — Captio AI keeps a deaf or hard of hearing person connected to everyday home life in a Danish household.

🤝Introducing someone new

Meeting a hearing Danish friend, partner's family member, or new neighbour. Captio AI captures their speech in real time so the first conversation can be natural.

👥Mixed group settings

At a Danish julefrokost, birthday gathering, or group dinner where voices overlap and conversation moves fast, Captio AI captions the room so a deaf or hard of hearing person is part of it.

Why Captio AI

You talk. They follow. No adjustment needed.

You speak naturally

No slowing down, no special phrasing, no training required. Captio AI handles everything — you just talk the way you always do.

They read as you speak

Your words appear on their screen word by word while you are still talking. Not a summary after — the full sentence, in real time.

Works wherever you both are

Living rooms, offices, restaurants, social gatherings. No venue setup, no special conditions. Captio AI works anywhere you have a conversation.

No sign language from either side

You do not need to learn anything new. Neither do they. Captio AI bridges the gap without requiring any change to how either of you communicates.

Works with how you actually speak

Fast, accented, casual. Captio AI handles real speech — not just slow, clear dictation. You do not need to perform clarity for it to work.

Private by default

Your conversations are never recorded, stored, or shared. Audio is processed in real time and discarded immediately — nothing is kept.

Danish

Why Danish is hard to understand

The stød

  • A phonemic distinction made entirely in the larynx
  • The stød — a laryngeal creaky phonation — distinguishes word pairs in Danish with no lip movement at all. 'Man' (one/pronoun) vs 'mand' (man/noun) are differentiated only by this voice quality. For a lip reader, both words look identical.

Plosive lenition

  • Stop consonants dissolve between vowels
  • Danish weakens and sometimes deletes stop consonants in intervocalic position — 'hvad' (what) becomes 'va', 'det er' (it is) becomes 'dear'. The lips stop and restart in patterns that hearing listeners fill in automatically, but that leave lip readers with empty space where a consonant should be.

Swallowed syllables

  • Final sounds are famously deleted in everyday speech
  • Danish systematically deletes final consonants and even full syllables. 'Ikke' (not) becomes 'i', 'selvfølgelig' compresses to two audible syllables. The written form and spoken form diverge so sharply that lip readers who use text as a guide are regularly misled.

27-vowel inventory

  • Many vowels with near-identical lip positions
  • Danish has approximately 27 vowel phonemes including distinctions of height, backness, rounding, and length. Several contrasts — particularly among the central and front vowels — produce nearly identical lip configurations, making vowel-by-vowel lip reading unreliable in Danish.

Dialect gap

  • Jutland, Funen, and Bornholm sound very different from Copenhagen standard
  • Standard Danish broadcasting is based on Copenhagen speech, but everyday Danish comes from Jutland dialects, Funen patterns, and Bornholmsk — all with different vowel systems and different rates of consonant deletion. A lip reader calibrated to broadcast standard encounters unfamiliar patterns in everyday family speech.

The Challenge

In Denmark, 40% employment for deaf adults — in a country with 77% general employment rates.

The Danish Deaf Association estimates that approximately 5,000 people in Denmark are deaf sign language users, with up to 20,000 using Danish Sign Language (DSL) daily. Despite Denmark's strong welfare state, a 2019 study found that only around 40% of deaf and hard of hearing adults are employed, compared to a general adult employment rate of 77% — a gap of 37 percentage points that reflects the structural barriers deaf people face in accessing work and workplace communication.

Adults with hearing loss in Denmark also experience significantly higher rates of physical and mental health conditions than the general population. A national survey (PubMed 28555382) found elevated incidences of depression, anxiety, and other mental disorders among adults with hearing loss, alongside higher rates of comorbidities including visual impairment and intellectual disability. These findings point to compounding exclusion: communication barriers in healthcare reduce access to the very services that could address elevated health risks.

Denmark has invested in some deaf-accessible media — DSL interpretation for certain broadcast news programmes — but interpretation services for everyday private life, family events, and workplace informal communication remain individually arranged. For the tens of thousands with hearing loss who do not use sign language, captioning and automatic speech recognition represent the primary accessible tool.

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.
