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.

Chinese

Why Chinese is hard to understand

Tonal compression

  • A conference room turns Mandarin tones into noise
  • Mandarin's four tones distinguish meaning — 妈/麻/马/骂 (mā/má/mǎ/mà) are four different words on the same syllable. In a conference room with air conditioning hum, projector noise, and overlapping voices, tonal distinctions compress and collapse. A deaf or hard of hearing person tracking speech visually has no way to recover tonal meaning — and the conference room is exactly where that environmental pressure is greatest.

Regional accents

  • A Beijing meeting can have five different accents of Mandarin
  • Chinese business meetings bring together speakers from different provinces. Shanghainese Mandarin carries Wu phonological features; southern Mandarin from Guangdong has distinct vowel patterns; Northeastern Mandarin has different vowel quality. A deaf person calibrated to standard Putonghua will miss significant portions of a colleague from Chengdu or Guangzhou — and there is no norm in Chinese business settings for speakers to adjust their pronunciation.

Meeting pace

  • Chinese meetings run fast, with interruptions and no turn-taking signals
  • Business meetings in China often involve rapid overlapping contributions, direct interruptions, and no visible signal before someone speaks. For a deaf or hard of hearing person tracking speech visually, an interruption means losing the thread entirely — and in a fast-moving Chinese meeting, interruptions are the norm, not the exception.

English–Mandarin mixing

  • Tech and international meetings switch languages mid-sentence
  • In Chinese tech companies, startups, and multinationals operating in China, meetings routinely blend Mandarin with English: 我们的roadmap要include这个feature到Q3. A deaf person following one language loses the thread the moment the other appears. The switch carries no signal and typically contains the meeting's most specific technical content.

Business register

  • Business Chinese uses a formal register absent from everyday speech
  • Chinese meetings operate in a formal register — 贵公司, 达成共识, 落地实施 — that differs significantly from conversational Mandarin. Combined with industry jargon and acronyms, the gap between what a deaf person recognises from daily life and what is spoken in a meeting room is substantial, and the formal register speeds up in meetings with no allowance for comprehension time.

The Challenge

27.8 million people. Excluded from the meeting room as well as the street.

China's 27.8 million people with hearing and speech disabilities face exclusion from professional life at a structural level. A study on China's disability employment legal framework (PMC, 2020) found that despite a statutory quota requiring employers to reserve at least 1.5% of their workforce for disabled employees, most disabled workers in China are confined to informal and low-quality employment. The quota is routinely not enforced, and employers consistently cite communication barriers as the primary reason for not hiring deaf workers — barriers that are never addressed in the workplace itself.

Chinese law has no formal recognition of sign language, which means there is no interpreter standard for workplace settings, no legal mandate for captioning in meetings, and no established protocol for accessibility in the professional environment. A deaf Chinese worker who joins a company is legally protected on paper but practically unsupported in the setting where their exclusion is most acute: the meeting room, the video call, the client presentation, and the team briefing where decisions are made and careers are shaped.

Hearing loss prevalence in China rose 125% between 1990 and 2021, according to a Global Burden of Disease analysis published in Frontiers in Public Health (2025), and is projected to continue increasing as China's population ages. Research using national survey data found that hearing loss is associated with 12.9% fewer annual work hours — a measurable reduction in professional participation that compounds over a career. The infrastructure to support deaf and hard of hearing people in Chinese professional life is not keeping pace. Captio AI captions Chinese speech in real time — across regional accents, formal business registers, and English–Mandarin code-switching — so the team meeting, the client pitch, and the job interview are no longer settings a deaf person has to navigate alone.
