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.

Bengali

Why Bengali is hard to understand

Aspirated pairs at meeting speed

  • Bengali's four-way consonant contrasts collapse entirely in fast meeting speech
  • Bengali uses four-way contrasts in stops — voiceless unaspirated (প), voiceless aspirated (ফ), voiced unaspirated (ব), voiced aspirated (ভ). These distinctions change meaning completely but are produced in the glottis with no visible lip shape difference. In a fast-moving meeting where a manager is running through deliverables, a deaf lip-reader misses the phonemic distinctions that carry the meaning of the most common Bengali business words.

Dhaka–Kolkata divide

  • Bangladeshi and West Bengali Bengali sound different in professional settings
  • Bangladeshi Bengali and West Bengali (Indian) carry distinct phonological features — different vowel quality, different prosody, different stress patterns. A deaf person calibrated to one will miss significant portions of the other. In meetings between Bangladeshi and Indian Bengali-speaking colleagues, or in diaspora corporate environments that mix both, this variation creates a comprehension barrier that no formal support addresses.

Code-switching

  • Professional Bengali mixes in English constantly — and the switch happens mid-sentence
  • Urban Dhaka and Kolkata professional communication runs on Benglish — the seamless mixing of Bengali and English that defines corporate, media, and NGO communication in both cities. A meeting agenda item might be stated in English, discussed in Bengali, and summarised in a mix. A deaf person following one language loses context the moment the other appears.

Formal register gap

  • Formal written Bengali and spoken meeting Bengali are different registers
  • Written Bengali, the formal standard used in official documents and formal presentations, is significantly more structured and deliberate than the fast, informal spoken Bengali of actual meeting discussion. A deaf person trained on written Bengali finds that the spoken meeting reality is far more compressed, faster, and harder to parse visually.

Loud open offices

  • Bengali workplaces in Dhaka and Kolkata are acoustically demanding
  • Open-plan offices in Dhaka and Kolkata are typically busy, loud, and built for verbal interaction. Background noise from conversations, traffic, and equipment is constant. The acoustic environment of a typical Bengali workplace is among the most challenging for a deaf or hard of hearing person, even before the meeting itself begins.

The Challenge

13 million in Bangladesh. Excluded from the formal economy, not just the meeting room.

Bangladesh has approximately 13 million deaf and hard of hearing people — one of the highest proportions in South Asia. The country recognised Bangla Sign Language in 2019, but recognition has not translated into workplace access. There are no BDSL interpreters in corporate offices, no captioning standards for business meetings, and no employer guideline addressing the communication needs of deaf employees. For the small proportion of deaf Bangladeshis who reach formal employment, the meeting room is the most consistently inaccessible daily setting in their professional life.

The employment pipeline for deaf people in Bangladesh is broken well before the workplace. Research on hearing loss and disability in Bangladesh documents that the deaf population faces cascading barriers: limited school access, exclusion from vocational training, and employer reluctance to hire. For those who overcome these barriers and reach formal employment, there is no institutional support awaiting them — no sign language interpreter, no captioning provision, and no workplace policy that treats meeting accessibility as a basic requirement.

In West Bengal, India, the Bengali-speaking deaf and hard of hearing population faces comparable barriers in a different legal framework — India's RPWD Act provides formal protections but no meeting-specific standards, and the interpreter shortage is acute. The Bengali-speaking professional world — spanning Bangladesh, West Bengal, and a significant diaspora in the UK — is growing in formal sector employment and remote work. The infrastructure to support deaf and hard of hearing people in Bengali-language meetings is not growing with it. Captio AI captions Bengali speech in real time — including Dhaka and Kolkata varieties, Benglish code-switching, and formal register — so every meeting is accessible.
