Yellow.ai is celebrating its 10th anniversary, and the Bangalore-born company has launched its first enterprise voice AI, forged by a decade of experience solving India’s toughest conversational AI problems. Vox can be deployed in over 20 Indian languages and over 500 languages around the world.
bengaluru, india, May 6, 2026 /PRNewswire/ — Ten years ago, three friends sat in a room in Koramangala with the idea that through AI, companies could talk to their customers in the language they actually speak. The Indian startup world was chasing food delivery. Enterprise AI was never a category.
Ten years later, Yellow.ai has enabled billions of conversations for more than 600 companies in 85 countries. And in its 10th year of existence, the company is launching products that a complex and demanding market like India demands.

Today, Yellow.ai announced nexus vox — First enterprise voice AI built as a single integrated system rather than stitching together APIs from multiple vendors. The product supports Native support for over 500 languages and dialects — includes all major Indian languages, plus Hinglish and dozens of regional dialects. End-to-end latency is less than 400ms, within the threshold of natural human conversation.
For Indian businesses, this changes everything.
Issues that India knows better than anyone
India moves with voice. A country of 1.4 billion people and hundreds of languages and dialects. Enterprise voice automation has never been able to keep up.
The reason is architectural. Today’s enterprise voice systems are Frankenstein stacks. One vendor is speech recognition, another is speech synthesis, a third is conversational AI, and a fourth is telephony. Each handoff adds 100-200 ms delay. Round-trip response times reach over 800ms, long enough to make every conversation feel robotic. And with most platforms supporting fewer than 30 languages, the majority of India’s population is left on hold or hung up.
”Enterprise voice AI was Frankenstein’s monster. Multiple vendor APIs were strung together, each increasing latency, each introducing points of failure, and none effectively solving customer problems.,said Raghu Ravinutala, co-founder and CEO of Yellow.ai.We’ve spent a decade solving India’s toughest enterprise AI problems. India has taught us that if AI can’t speak the customer’s language fluently, instantly, and in the customer’s accent, it’s not AI. It’s an IVR with a better UI. Vox is built on a completely different architecture. ”
How Nexus Vox works
Nexus Vox runs natively within Yellow.ai’s Nexus platform and shares the same runtime as its conversational AI, knowledge base, and automation engine (what Yellow.ai calls it). “Zero hop architecture”. There are no API round trips between voice processing and conversation processing.
Main features:
- End-to-end delay from customer utterance to AI voice response is less than 400ms — within the bounds of natural human speech.
- Natural, human-quality speech synthesis for over 500 languages and dialects
- Create audio clones from any audio sample in 10 seconds — Maintains the timbre, rhythm, and emotional range of the original speaker. Indian businesses can replicate their brand voice and expand it to all the languages they offer.
- Real-time emotion recognition — Vox adjusts tone, pace, and escalating behavior during conversations. This is important for emotional calls, such as insurance claims or service complaints.
- Omnichannel deployment Run telephony (SIP/PSTN), web widgets, and REST APIs from a single configuration.
- CX and EX on one platform — Built for both customer-facing and employee-facing voice automation. They are not two separate products.
- Sarvam AI integration — Vox is natively integrated with Sarvam AI’s sovereign Indian language model, built under the Indian government’s IndiaAI mission and trained from the ground up on Indian language data.
Forged in India. Ready for the world.
Yellow.ai’s ability to build Nexus Vox is inseparable from its 10 years in India.
Edelweiss General Insurance launches India’s first end-to-end AI voice bot for auto insurance claims, powered by Yellow.ai, that processes Hinglish 24/7 from a noisy garage. A claimant makes a stressful phone call after an accident, switching between Hindi and English mid-sentence, and the AI processes the entire implication, including name, address, license number, etc., in real time. Issues like this force us to build voice AI differently.
Sony India introduced Isha, a voice AI agent that provides 24-hour support in English, Hindi and Bengali, and fielded over 21,000 customer and dealer calls within two months of launch.
These use cases allow Yellow.ai to solve problems that other markets do not require at this scale and language complexity. Nexus Vox is the product that made these problems inevitable.
Business reflects betting. Yellow.ai is currently EBITDA positive — a rarity in an industry where most AI companies are still wasting money. Revenue has grown to tens of millions of dollars annually CAGR 70%, worldwide consolidated growth rate 40%. And rather than retreat, the company is increasing its investments in India, expanding its engineering center in Bengaluru and deepening its partnerships in the region.
”Every AI company is talking about India as its future market. For us, India has been a market since day one, a market that has benefited us, trained our platform and invested deeper.,” said Ravinutara.India is the toughest AI market on the planet. Hundreds of languages, 1 billion WhatsApp users, and corporate buyers demanding world-class AI in the Indian economy. We don’t see it as a challenge. We think that’s why we were able to build Vox. India didn’t just give birth to Yellow.ai. India has trained us to solve problems of scale.”
What Nexus Vox means for Indian businesses
