Who's Actually Building India's Voice AI Stack in 2026?
Everyone talks about "Voice AI in India" like it's one market. It isn't. A company selling SIP trunking to a bank has almost nothing in common with a startup fine-tuning a Hindi text-to-speech model, but both get lumped under the same buzzword. That confusion is getting worse, not better, because the fastest-growing layer, voice agent platforms, now has more than 40 companies chasing the same handful of use cases: sales calls, support calls, and collections calls in Indian languages.
Here's the direct answer: India's voice AI stack runs across nine distinct layers, from telephony infrastructure at the bottom to non-profit public-service rollouts at the top, and the real action right now is split between the crowded agent-platform layer and the foundational speech-model layer underneath it, where Sarvam, Gnani, BharatGen, and Maya Research are racing to build Indic-language models good enough for everyone above them to build on.
This piece maps all nine layers, company by company, so builders can tell who's actually selling what.
What Question Does This Piece Answer?
If you're trying to figure out where a voice AI company fits, who they compete with, and what layer of the stack they actually sit in, this is the map. Categories blur on purpose in marketing copy; they don't blur here.
Why Are Telephony And Voice Agent Companies So Easy To Mix Up?
Telephony companies own the phone lines. Voice agent companies own the conversation. A telephony player like Exotel gives you the number, the routing, and TRAI DLT compliance; an agent platform like Bolna or Ringg.AI plugs into that number and decides what to say. The two used to be cleanly separated. They aren't anymore, mostly because telephony companies watched agent platforms eat their margins and decided to build AI on top of their own pipes.
Exotel is the clearest example. It pioneered voice APIs in India before "CPaaS" was even a term people used, and it has since acquired Ameyo (contact center software) and Cogno AI (conversational AI) to stop being just a dial tone. Plivo took the opposite path, staying a pure global CPaaS provider spanning voice, SMS, and WhatsApp APIs across 190+ countries. Knowlarity remains one of the largest cloud communication providers in India by sheer scale of virtual numbers issued.
Company | Website | What They Do |
|---|---|---|
Exotel | Voice API pioneer in India; now bundles CPaaS, contact-center software (via its Ameyo acquisition), and conversational AI (via Cogno AI) into one stack | |
Plivo | Global CPaaS provider offering pay-as-you-go Voice, SMS, and WhatsApp APIs across 190+ countries | |
TeleCMI | Chennai-based cloud communications platform with AI-driven call routing, analytics, and hosted PBX for remote teams | |

Vobiz | Cloud calling infrastructure player; limited public detail available, worth verifying directly before evaluating | |
Knowlarity (Knowl) | One of India's largest cloud communication providers by scale: virtual numbers, IVR, and cloud call-center tools |
Why Is The Voice AI Agent Layer So Crowded?
Because the barrier to entry is low and the demand is real. Any team that can wire together a speech-to-text model, an LLM, and a text-to-speech model can ship a demo in a weekend. Actually running that demo in production, at scale, in Hinglish, with TRAI DLT compliance and sub-second latency, is a different problem entirely, and that gap is why this category has both dozens of thinly differentiated startups and a handful of companies pulling ahead on real deployments.
Three names are worth knowing specifically because they get miscategorized constantly: Blue Machines built an enterprise voice AI system, partnered with Cartesia, that made headlines for holding a live unscripted debate against Arnab Goswami on Republic TV as a public stress test. Arrowhead, a Bengaluru startup, raised a $3M seed led by Stellaris Venture Partners in January 2026 and focuses squarely on BFSI voice agents, with clients including Bank of Baroda Cards, Paytm, and Aditya Birla Capital. NuPlay, formerly Nurix AI and backed by Accel and General Catalyst, recently rebranded and acquired Verloop.io, folding chat automation into its voice stack.
A few others have enough of a public footprint to describe with confidence, including GreyLabs AI (BFSI-focused, ₹85 Cr Series A led by Elevation Capital in late 2025), SuperBryn (a Bengaluru observability/evals layer for voice agents that raised a $1.2M pre-seed from Kalaari Capital's CXXO), RevRag AI (in-app and calling agents for BFSI onboarding drop-off), Dograh (an open-source, self-hostable alternative to Vapi/Retell), and Babblebots.ai (voice-AI interview agents for recruitment):

Who's Actually Building The Speech Models Underneath All This?
This is the layer that matters most and gets talked about least. Every agent platform above is a wrapper around someone else's speech-to-text, text-to-speech, and language models, unless it's built its own. Right now, a handful of Indian labs are racing to make Indic-language models good enough that the whole stack above them stops depending on foreign models tuned for English.
Sarvam AI, founded in 2023 by Vivek Raghavan and Pratyush Kumar, is the most visible name here. It's one of the companies selected by MeitY to build a sovereign foundational model under the IndiaAI Mission, and in February 2026 it released new 30-billion and 105-billion parameter open-source models alongside dedicated speech-to-text and text-to-speech models. Gnani.AI is building a 14-billion parameter speech-to-speech model under the same government program. BharatGen, an IIT Bombay-led consortium, received the largest chunk of government funding among the 12 supported organizations, over ₹1,058 crore, and launched its own suite of speech, text, document-vision, and text-to-speech models at a June 2026 summit. Maya Research, a two-person Bengaluru startup founded in 2025 by recent NYU graduates, built its open-source Maya1 voice model on free cloud credits with no venture funding before it later raised $1.9 million; the model briefly ranked in the top handful of open-weight voice models globally on the Speech Arena leaderboard.
Company | Website | What They Do |
|---|---|---|
Sarvam AI | Bengaluru AI lab building LLMs and speech models for Indian languages; government-backed sovereign model developer; released 30B/105B open models in Feb 2026 | |
smallest.ai | Lightweight, low-latency text-to-speech models (sub-100ms) built for business applications and voice cloning | |
Shunya Labs | Research-forward voice AI company building custom speech models, voice agents, and secure Indic AI deployments | |
Maya Research | Bengaluru startup behind Maya1, an open-source TTS model that ranked among the top open-weight voice models globally; $1.9M raised in 2025/26 | |
BharatGen | IIT Bombay-led government-funded consortium building sovereign multimodal models for Indian languages: speech (Shrutam), text (Param), document vision (Patram), and TTS (Sooktam) |
What Happens To Voice Data After The Call Ends?
Conversation intelligence is the layer nobody notices until a compliance audit or a bad quarter forces someone to ask "what did our agents actually say on these calls?" These tools record, transcribe, and score calls after the fact, and increasingly in real time.
Convin markets itself as a full contact-center conversation intelligence suite: automated QA across 100% of calls, live agent-assist prompts, and an AI-driven learning management system for coaching. Mihup positions directly against Convin on the strength of native support for 120+ Indian languages and proprietary phoneme-level technology for Indic speech, with BFSI clients like Titan and Asian Paints. ConvoZen has moved further up the stack into running AI-powered outbound calling and WhatsApp campaigns on top of its conversation-intelligence base.
Company | Website | What They Do |
|---|---|---|
CONVIN | Contact-center conversation intelligence: 100% automated QA, real-time agent assist, and AI-driven coaching across calls, chats, and emails | |
ConvoZen | Conversational intelligence platform that has expanded into running its own AI calling and WhatsApp campaigns | |
Mihup | India-focused conversation intelligence with native support for 120+ Indian languages and real-time agent assist; used by Titan, Asian Paints | |
VocalLabs | Conversation intelligence and QA player in the Indian contact-center market; limited independent public detail | |
Prodloop | Conversation intelligence and QA player in the Indian contact-center market; limited independent public detail |
Where Does Localization Fit Into The Voice Stack?
Localization and dubbing sit slightly outside the calling stack but feed everything above it, no agent platform or foundational model is useful in 22 languages without the language data and adaptation work this layer does. Devnagri has repositioned itself as a "sovereign language AI infrastructure layer," aimed at helping regulated enterprises run audit-ready workflows across languages rather than just translating marketing copy. Desible.ai, a Bengaluru startup, has built a multichannel (voice, WhatsApp, SMS, email) automation engine that leans heavily on localized, human-like voice interactions for BFSI and health-insurance clients.
Company | Website | What They Do |
|---|---|---|
Devnagri | Sovereign language AI infrastructure for regulated enterprise workflows across Indian languages, with audit-ready, domain-trained models | |
desible.ai | Bengaluru-based multichannel (voice, WhatsApp, SMS, email) automation platform for enterprise customer conversations, used by BFSI and health-insurance clients | |
60db | Dubbing and audio-localization player; limited independent public detail |
Is Voice AI Just Part Of A Bigger CX Platform Now?
For the largest consumer internet companies in India, yes. Zomato's Nugget is the sharpest example: it started three years ago as an internal tool and now handles over 15 million support interactions a month across Zomato, Blinkit, and Hyperpure, combining AI voice agents, real-time learning, and automated quality audits, before Zomato spun it out as a product other businesses can buy. Haptik, founded in 2013 and acquired by Reliance's Jio Platforms in 2019, remains one of the older players here, running mobile-first conversational AI across WhatsApp, web, and voice for telecom and fintech clients.
Worth tracking as consolidation rather than a standalone story: Verloop.io used to be an independent CX platform in this category, but it's now part of NuPlay (formerly Nurix AI) after that acquisition.
Company | Website | What They Do |
|---|---|---|
Haptik | Mobile-first conversational AI platform (owned by Jio Platforms) spanning voice, WhatsApp, web, and app channels for telecom and fintech use cases | |
BotSpace | Multi-channel CX platform combining chat and voice automation; limited independent public detail | |
Nugget (by Zomato) | Zomato's internally built AI support platform, now offered externally; handles 15M+ interactions/month across Zomato, Blinkit, and Hyperpure |
What's The Difference Between A Voice AI Platform And A BPO That Uses One?
BPO-tech companies still put human callers on the phone, they've just started layering AI tooling underneath them: quality monitoring, lead routing, and now voice agents working alongside human agents rather than replacing them outright. SquadStack is the clearest case of a company outgrowing its own category. It started as a human calling-talent marketplace and now markets itself as "India's largest-scale Voice AI platform for consumer sales," blurring the line between BPO-tech and category 2 above. Whether it fully repositions as a pure agent platform is worth watching over the next year.
Company | Website | What They Do |
|---|---|---|
SquadStack | Started as a human-calling talent marketplace, now markets itself primarily as a large-scale voice AI platform for consumer sales | |
Futwork | Gig-based human calling workforce platform, blending distributed human agents with quality and routing tooling |
What Non-Voice Infrastructure Do These Companies Lean On?
Not everything in this stack is voice-specific. videosdk provides live video and WebRTC infrastructure, Surat-based and GVFL-backed, that voice AI companies frequently reach for when they need real-time media pipes alongside their calling stack.
Company | Website | What They Do |
|---|---|---|
videosdk | Live video and WebRTC infrastructure provider; not voice-specific but commonly used alongside voice AI stacks |
Is Any Of This Being Used For Public Good, Not Just Sales Calls?
Yes, and it's the category most likely to get skipped in a "top voice AI companies" list because it isn't a company at all. EkStep Foundation, a non-profit digital public goods foundation behind projects like Sunbird and ONEST, recently co-ran "Listen at Scale" with Sarvam and AI4Bharat, a multilingual voice AI rollout reaching millions of citizens across healthcare, agriculture, and government services.
Organization | Website | What They Do |
|---|---|---|
EkStep Foundation | Non-profit digital public infrastructure foundation; co-ran "Listen at Scale," a multilingual voice AI rollout with Sarvam and AI4Bharat reaching millions across healthcare, agriculture, and government services |
Where Is This Heading Next?
The next 12 months will separate the agent-platform layer into two tiers: a small group of companies with real production deployments, DLT-compliant infrastructure, and vertical depth in BFSI, healthcare, or collections, and a much larger group still selling demos. Consolidation is already starting, NuPlay folding in Verloop.io and SquadStack drifting into pure voice AI positioning are both early signs. The layer to watch closest, though, is foundational models: Sarvam, Gnani, BharatGen, and Maya Research are all racing to build Indic speech and language models good enough that the entire agent-platform layer stops depending on foreign models tuned for English, and whoever wins that race effectively sets the cost floor for everyone building on top.
