Why Captio AI

Built for the speed of a real meeting

Captions while they are still speaking

Words appear on screen as each person talks — not after they finish. You read what someone is saying at the same moment everyone else hears it.

Works in any meeting format

Conference rooms, open-plan offices, video calls, all-hands. Place the phone on the table or hold it — Captio AI handles the rest.

Handles fast speech and crosstalk

Captio AI is designed for real meetings, not controlled dictation. It follows whoever is speaking loudest at any moment, keeping up with the natural pace of discussion.

No setup, no explaining

Open the app and place the phone. No pairing, no telling colleagues what you are doing, no requesting anything from the meeting organiser.

Review everything after

Record the meeting and upload it to Audio Transcription for a full written record. Use AI Summary to extract decisions and action items so nothing from the meeting gets lost.

60+ languages

For international teams, multilingual meetings, or colleagues who switch between languages mid-discussion. No setup required — Captio AI detects and captions in real time.

Portuguese

Why Portuguese is hard to understand

Nasal vowels at speed

  • Nasal Portuguese at meeting pace reduces visible mouth movement to almost nothing
  • Brazilian Portuguese nasal vowels — ã, ẽ, õ — are a defining phonological feature, and at casual meeting speed they produce very little visible lip movement. When a manager is running through a project update at natural pace, the nasal articulation makes word boundaries and phoneme distinctions visually indistinguishable. Lip-reading a Brazilian standup or client call is structurally compromised in a way that affects common business vocabulary at every sentence.

Brazil vs Portugal in meetings

  • European Portuguese in a global call is harder to follow than Brazilian
  • European Portuguese reduces unstressed vowels so dramatically that Brazilians often struggle to understand it by ear. In a multinational meeting with Portuguese and Brazilian participants, a deaf person accustomed to Brazilian pronunciation will miss large portions of what the Lisbon colleague says — and vice versa. Global Portuguese-language companies have no accessibility standard that addresses this intra-language variation.

Interrogative intonation

  • Brazilian questions look identical to statements on the lips
  • Brazilian Portuguese forms questions primarily through rising intonation rather than changed word order. 'Você aprova.' (You approve.) and 'Você aprova?' (Do you approve?) are identical lip movements — distinguished only by pitch, which is entirely invisible to a deaf person. In a meeting's Q&A or decision moment, getting statement and question confused changes what the conversation means entirely.

Gíria in office speech

  • Brazilian office culture uses a fast informal register in all but the most formal moments
  • Brazilian professional culture is warm, informal, and relationship-driven — which means the formal register of an official presentation quickly gives way to gíria (slang), dropped vowels, and the compressed casual speech of real Brazilian interaction. The formality level shifts mid-meeting, and with it the visual parsability of what is being said.

English code-switching

  • Brazilian tech and business meetings mix Portuguese and English constantly
  • Brazilian corporate culture — especially in tech, startups, and multinationals — mixes Portuguese and English mid-sentence for technical vocabulary, product names, and strategic concepts. 'Precisamos de mais budget para esse sprint' is standard São Paulo office speech. A deaf person following one language loses the thread when the other appears, without warning.

The Challenge

2.3 million Brazilians with profound hearing difficulty. The meeting room was never designed for them.

Brazil has 2.3 million people who cannot hear at all or can hear only loud sounds, according to IBGE's 2019 National Health Survey (PNS). Among working-age Brazilians with hearing impairment, the employment-population ratio is only 25.4% — less than half the rate for hearing individuals. Only 28.3% of all working-age Brazilians with disabilities are in the workforce at all, compared to 66.3% of those without disabilities. For those who do reach formal employment, the meeting room is the setting where their exclusion becomes most acute and most invisible.

Brazil recognised Libras in 2002, but outside of formal educational and legal settings, Libras provision in the corporate sector is almost entirely absent. Research on access to health services among deaf Brazilians (SciELO) consistently documents communication barriers as the primary driver of exclusion — and the corporate sector offers fewer formal accommodations than healthcare. Most Brazilian companies have no captioning provision, no interpreter policy, and no workplace accessibility standard that addresses the daily reality of a deaf employee attending meetings in Portuguese.

Brazil's fast-growing tech sector, its large remote-work workforce, and its expanding multinational corporate presence have created more meeting-heavy professional environments than at any previous point in the country's history. The deaf and hard of hearing professional population is navigating this meeting-dense work culture without support. Captio AI captions Brazilian Portuguese in real time — including nasal vowels, gíria-heavy informal registers, and English-Portuguese code-switching — so the standup, the client call, and the job interview are accessible.
