THE PROBLEM
Most AI was never designed for India’s last mile.
English-first AI works for head offices. It fails the 400 million field workers who power Indian enterprise.
English-only interfaces lock out the field
A delivery agent in Patna should not need to speak English to check his load plan. But most enterprise apps require exactly that.
Low connectivity kills app adoption
Apps designed for 4G LTE do not work on 2G rural networks. Offline-first is not optional, it is a requirement for Bharat-scale.
ERP data stays in HQ
Inventory levels and pricing updates sit locked in SAP. Field workers call managers. Managers call the ERP team. Everyone waits.
WHAT VAANI OS DOES
The voice layer India’s enterprise was missing.
Built from the ground up for Indian linguistic diversity, connectivity constraints, and enterprise data systems.
Hindi & Regional ASR
Speech recognition trained on Indian accents, code-switching (Hinglish), and regional dialect variations, not just textbook Hindi.
Conversational NLU
“Kal ka delivery kab aayega?” resolves to a delivery-status query instantly, no translation step required.
IVR Integration
Deploy over existing IVR infrastructure. Workers call a number, speak their query, get a response. No app install required.
WhatsApp Business API
Reps interact via WhatsApp, voice messages, text, or images. Orders and queries flow through a channel they already use daily.
ERP & Backend Integration
Connects to SAP, Oracle, or your internal systems. Vaani retrieves and updates live data, no manual lookup, no waiting for a reply from HQ.
Offline & Low-Bandwidth
Critical queries cached locally. Voice input still captured on 2G, synced when connectivity returns. Graceful degradation built in.
HOW IT WORKS
Deployed in three channels. One platform.
Vaani OS meets workers where they already are: on their phone, on WhatsApp, or on a call.
1
STEP 1
Worker places a query
Via IVR call, WhatsApp message, or the mobile app, in Hindi or their regional language.
2
STEP 2
ASR & NLU processing
Speech is transcribed, intent extracted, and language understood, including code-switching and dialect variations.
3
STEP 3
ERP data fetched
Vaani OS queries the connected backend, SAP, Oracle, or your internal system, for live, accurate information.
4
STEP 4
Response delivered
Answer returned in the worker’s language, via the same channel they used. No app switching, no escalation to HQ.
INTEGRATION
One voice query. Answered in any language.
Deploy over the channels your workforce already uses. No app rollout, no new hardware.
