Use Cases

Every situation covered

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

👨‍👩‍👧Family conversations

Telugu family meals in Andhra Pradesh or Telangana — at home in Vijayawada, Hyderabad, or Visakhapatnam — often move fast, with multiple family members speaking in overlapping conversational Telugu. A hearing family member speaks naturally and quickly. Captio AI captions what they say word by word so a deaf or hard of hearing family member stays in the conversation.

💼As a hearing colleague

Telugu workplaces in Hyderabad run in a fast mix of Telugu, English, and Urdu loanwords for everyday talk. A hearing colleague speaks in whichever blend comes naturally. Captio AI captions what they say in real time so a deaf or hard of hearing colleague follows desk conversations and quick questions without missing a beat.

❤️Partners and relationships

When your partner is deaf or hard of hearing and Telugu is your home language. You speak naturally. Captio AI puts every word on their screen as you say it — no slowing down, no repetition, no typing between you.

🏠Living together

Daily home life in a Telugu household — calling from across the house, talking during the evening serial, quick questions while getting ready. Captio AI covers all the small everyday exchanges that add up to connection over time.

🤝Introducing someone new

When a deaf or hard of hearing person meets a new hearing Telugu speaker — at a family function, a community gathering, or a temple event. Captio AI captions the new person's speech naturally so the meeting is not shaped by the communication gap.

👥Mixed group settings

Group settings — a family gathering for Ugadi, a large multi-generation household, a community event — where some people are deaf or hard of hearing and some are not. Captio AI captions whoever is speaking so every person at the table is fully part of the conversation.

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.

Telugu

Why Telugu is hard to understand

Retroflex and dental contrast

  • The retroflex-dental distinction in Telugu is invisible at the lips
  • Telugu distinguishes dental /t/, /d/ from retroflex /ʈ/, /ɖ/ — a contrast that is invisible at the lips. The tongue position differs internally, but the mouth shape is nearly identical. In everyday Telugu family speech, these distinctions matter for meaning but produce the same visual signal for a deaf lip-reader.

Coastal–Rayalaseema–Telangana split

  • Telugu across three dialect zones is three different lip-reading tasks
  • The three major Telugu dialect zones have different vowel qualities, some vocabulary differences, and distinct prosodic patterns. A deaf person who lip-reads Coastal Telugu (Vijayawada, Visakhapatnam) faces a shifted phonological map when a hearing family member from Hyderabad or Kurnool speaks their home variety.

Fast conversational contraction

  • Casual Telugu contracts the syllables a lip-reader expects to see
  • Telugu casual speech contracts heavily: long verb forms shed syllables at full conversational pace. Word-final syllables are swallowed in fast family conversation, leaving a deaf lip-reader seeing only fragments where they expect complete forms. The compression is natural for hearing speakers and invisible without sound.

Agglutinative suffix blur

  • Long Telugu verb forms arrive as a single visual blur at full speed
  • Telugu verbs and nouns carry multiple suffixes encoding tense, aspect, and politeness. In fast speech, a complex form is delivered as a single breath group. A lip-reader sees the lips moving rapidly through many positions, but the boundaries between morphemes are invisible — the whole word becomes a single visual blur.

Hyderabad Telugu–Urdu switching

  • Hyderabad Telugu switches to Urdu loanwords without any visual signal
  • In Hyderabad, Telugu is heavily inflected with Urdu loanwords and spontaneous code-switching. For a deaf lip-reader tracking Telugu, unexpected Urdu lexical items from a different phonological origin are unrecognisable without the auditory cue — suddenly the mouth shape doesn't match any Telugu word they know.

The Challenge

Hearing loss in Telangana and Andhra Pradesh: high prevalence, limited access

A community-based study in Mahabubnagar District, Telangana found that 4.5% of the population — approximately 1 in 23 people — had disabling hearing impairment, rising to 34.7% among those aged over 65 (PubMed 29782444). Extrapolated across Telangana's population, this represents hundreds of thousands of people navigating daily communication with significant hearing loss, the vast majority without access to audiological care, hearing aids, or specialist support. Andhra Pradesh shows similarly high rates, with districts in both states ranked among the highest for disability prevalence in India's NFHS-5 data.

India has one national sign language, Indian Sign Language (ISL), but penetration into Telugu-speaking communities in Andhra Pradesh and Telangana is limited outside Hyderabad and a few other major cities. For the majority of deaf and hard of hearing Telugu speakers — in smaller towns, in coastal fishing communities, in rural Rayalaseema — communication with hearing family members depends entirely on informal strategies: gesture, writing, or the hearing person's willingness to repeat and simplify. There is no formal support structure for daily family communication, and the adjustment burden sits entirely on the person who hears least.

WHO estimates that India accounts for a disproportionate share of the global burden of hearing loss, with over 63 million people experiencing significant auditory impairment (GBD 2019, PMC7960691). In households where a deaf or hard of hearing family member shares meals and daily life with hearing relatives who speak Telugu, the gap is structural — it does not improve without a tool that can bridge it. Captio AI captions natural Telugu speech in real time, at a Hyderabad dinner table or across a house in a coastal Andhra town, so that a deaf family member reads what their hearing relatives are actually saying.
