Use Cases

Every situation covered

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

🍽️Dinner with friends

A hot pot dinner in Beijing or Chengdu — eight people at a round table, lazy Susan rotating, everyone talking at once in fast Mandarin with regional accents mixing in. Captio AI captions each speaker so a deaf diner can follow across the table.

💼Business lunches

A business banquet at a Shanghai restaurant — dishes ordered communally, proposals discussed between toasts. Professional conversations that matter, in a noisy environment. Captio AI keeps every exchange accessible without drawing attention.

Cafe catch-ups

A tea house or milk tea café catch-up in Taipei, Hong Kong, or a mainland city — ambient music, background chatter, two people across a small table. Captio AI follows whoever is speaking in real time.

🌍Restaurants abroad

Ordering at a Chinese restaurant abroad where the menu is in English but the staff speak Cantonese — or dining with a companion who speaks a different language. Captio AI and Live Translator bridge the gap together.

🎂Celebrations and group meals

A Lunar New Year banquet, birthday dinner, or wedding table — ten people, elevated noise, toasts, and overlapping conversations. Captio AI makes the celebration followable from first toast to final course.

❤️Dates and one-on-one meals

A quiet dim sum catch-up or first date at a teahouse in Guangzhou or Hong Kong — Cantonese across a small table. Captio AI lets you follow every exchange without making the accommodation conspicuous.

Why Captio AI

Built for the table — however noisy the room

Follows the person across the table

Point the microphone toward the person speaking and Captio AI captions them through the background noise. You do not need to face them, watch their lips, or lean in.

Works through restaurant noise

Restaurant noise averages 80 dBA — well above comfortable conversation level. Captio AI is built for these real environments, not quiet controlled rooms.

Place it and forget it

Put the phone on the table between you and the other person, microphone facing them. You glance at it as needed. No adjusting between sentences, no managing the setup.

No asking for repeats during the meal

Every word appears in real time. If you missed something, the caption is there — you do not need to stop the conversation and ask anyone to say it again.

Any language

For restaurants abroad, multilingual dining companions, or waitstaff who speak a different language. Live Translator captions and translates in real time with no manual setup.

Discreet

A phone on a restaurant table is unremarkable. Captio AI runs quietly, the screen faces you, and most dining companions adapt naturally once they understand what it does.

Chinese

Why Chinese is hard to understand

Tonal collapse in noise

  • Zero acoustic and zero visual tonal information
  • Mandarin's four tones are produced laryngeally and are already invisible on the lips. Restaurant noise at 80 dBA strips away the minimal acoustic cues that remain for a listener with any residual hearing. At a hot pot or dim sum table, a deaf diner has no acoustic support and no visual tonal information — two independent signals, both lost.

Round-table oblique angles

  • Chinese dining layout defeats lip-reading
  • Chinese group dining uses round tables with a rotating lazy Susan. Diners sit at oblique angles to each other, rarely face-to-face. Lip-reading requires a direct view of the speaker's face. At a Chinese round table, the ideal lip-reading position exists for at most one or two seats — the rest of the table is sideways or distant.

Cantonese vs Mandarin service

  • The service language changes the visual system entirely
  • In Hong Kong, Guangdong province, and Chinese diaspora restaurants worldwide, Cantonese is the service language. A deaf diner trained on Mandarin lip shapes encounters a completely different visual phonological system at the counter or when ordering. Cantonese has nine tones — each as invisible on the lips as Mandarin's four.

Fast menu recitation

  • Servers rattle off specials with no pause
  • Chinese restaurant servers recite daily specials, available soup bases, and dish availability in rapid succession with no pause for confirmation. Even hearing diners miss details in this exchange. For a deaf diner, this brief but critical speech is completely inaccessible without external support.

Code-switching at upscale venues

  • Chinese and English mix without warning
  • In Hong Kong, Singapore, and Chinese diaspora restaurants worldwide, waitstaff and diners switch between Chinese and English for menu items, prices, and recommendations. For a deaf lip-reader, an unexpected English phrase where Chinese is expected breaks the visual pattern entirely — the mouth is suddenly forming a different system.

The Challenge

Hearing loss in China: the cost of dining exclusion

China has the world's largest deaf and hard-of-hearing population — 27.8 million people according to China's Second National Sample Survey on Disability. From 1990 to 2021, the prevalence and disability burden of hearing loss in China rose by 125% and 135% respectively, driven by an ageing population and occupational noise exposure. The number of people navigating daily Chinese life without adequate hearing is growing faster than the infrastructure to support them.

China has no formal national recognition of sign language as an official language. Interpreter services are concentrated in cities and institutions — not in the restaurants, tea houses, and banquet halls where the social fabric of Chinese life is woven. Research on hearing loss and social dining published in 2024 found that people with hearing loss disengage from restaurant dining at significantly higher rates — not because they do not want to go, but because the environment makes participation too costly. For deaf and hard-of-hearing Chinese people, every group meal carries this hidden cost.

Captio AI captions Chinese conversation in real time, so a deaf or hard-of-hearing person can follow a hot pot dinner in Chengdu, a dim sum gathering in Hong Kong, or a business banquet in Shanghai without missing a word.
