A complete guidance moment

From question to next step.

The demo shows how the assistant handles a real question, asks only what matters, and guides people to clear next steps.

Ask in everyday language

The caller asks a practical question in Hindi or English using an ordinary phone. No app and no typing are needed.

Clarify only what matters

BadaBhai asks a short follow-up when it needs context, then explains likely next steps in plain language.

Repeat and offer the official route

The caller can ask to repeat key details. The demo shares general information, not personal account data.

Built for guidance, not decisions. The demo shares general information. It does not determine eligibility, access personal records, or claim government endorsement.

Why access matters

AI should work for the phone people already have.

Voice can reduce barriers created by device cost, mobile data, reading confidence, app setup and unfamiliar digital services. GSMA estimates about 200 million new feature phones sold globally in 2024; India shipments were about 54 million, attributed to IDC.

Reach beyond smartphones

A call-based interface can bring guided help to feature-phone users and people with limited internet access.

Make complex steps clearer

People can ask follow-up questions, hear information repeated, and move at their own pace in a familiar conversation.

Connect people to answers

With approved information sources, guidance can be grounded and routed to verified next steps.

Where this could go next · global

A starting point.
Not an endpoint.

Around 200 million feature phones were sold worldwide in 2024. India accounted for about 54 million shipments. These are annual sales estimates, not counts of active users. Voice on an ordinary call could make AI useful beyond smartphone apps and beyond India.

Explain everyday topics simply

Maths, science and how-to guidance on a feature phone, in Hindi, English, Swahili, Bahasa Indonesia and more as each language is validated.

Help governments reach people

With verified sources, public agencies could explain program purpose, required documents, deadlines and official helplines in local languages.

Explore better speech models

With separate opt-in, strong anonymization and local governance, speech in Bhojpuri, Tamil, Marathi, Swahili, Hausa, Bahasa Indonesia and Tagalog could support research on voice-token models, language control, native prosody and code-switching. This could inform Meta research for more natural multilingual AI, but the demo does not train models or use calls for training.

Replace long enterprise IVR menus

Callers could describe an issue such as “My bill seems too high” and reach the right self-service path or staff team. Account changes still require authorization.

Enable voice orders from villages

Local marketplaces could take voice orders for groceries or farm supplies and connect them to logistics beyond cities.

Translate live calls

Future speech systems could help a farmer speaking Hindi talk with an English-speaking buyer, if accuracy, latency and consent are handled well.

These are future possibilities that require approvals, infrastructure, consent and local partnerships. BadaBhai today is an independent hackathon prototype, not a Meta or government service.

Live call experience
