ConvoZen vs GreyLabs AI: Comparing Voice AI for BFSI Contact Centers 2026

Contact centers in Indian BFSI handle thousands of compliance-heavy calls a day, and most quality assurance teams still audit only a small fraction of them. That gap between call volume and audit coverage is where conversational AI vendors are competing hardest right now. Gartner projects that conversational AI deployments inside contact centers will cut global agent labor costs by $80 billion in 2026, a sign of how fast voice automation has moved from pilot to production budget line.

ConvoZen and GreyLabs AI are both building for this shift, from different starting points. ConvoZen, a contact center and conversation intelligence product built by NoBroker, is an omnichannel conversational AI platform deployed across BFSI, insurance, edtech, proptech, healthcare, and D2C. 

GreyLabs AI is a voice AI platform built exclusively for banks, NBFCs, insurers, and broking firms. This comparison covers focus, channels, language technology, compliance use cases, and commercial model, drawing only on what each company has published.

One Industry vs Several

GreyLabs AI’s product depth sits entirely inside BFSI. Its founding team previously built Cogno AI, a banking-focused conversational AI platform acquired by Exotel in 2021, and GreyLabs has carried that domain focus into voice AI agents for sales, collections, renewals, and policy verification calls . For a bank or NBFC that needs nothing outside this scope, that narrowness can translate into a more tailored sales pitch from day one.

ConvoZen runs comparable BFSI use cases, loan SOP monitoring, collections compliance tracking, and sales rejection analysis, on a platform also deployed in edtech, proptech, insurance, healthcare, and e-commerce. For a financial institution that also runs lending, insurance, or retail lines under one group, or one that expects its conversational AI vendor to support adjacent business units later, that breadth removes a future vendor decision rather than creating one now.

Speech and Language Technology

ConvoZen’s Akshara speech-to-text model is benchmarked against Sarvam Saaras v3 and ElevenLabs Scribe v2 across 9 Indian languages and over 16 hours of evaluation audio, with full methodology and per-language results published in a dated report. On the telephonic-speech benchmark specifically, the closer proxy for real contact center audio, Akshara posts a 20.2% word error rate against 36.2% for Sarvam Saaras v3 and 58.5% for ElevenLabs Scribe v2, a 44% and 65% relative improvement. 

ConvoZen pairs this with the Ragini text-to-speech model, trained on 800+ hours of proprietary Indian voice acting with sub-200ms audio generation latency, and an MSOC architecture that preserves conversation context across channels and sessions.

GreyLabs AI’s public materials describe a speech-to-text engine tuned specifically for BFSI terminology, with third-party trackers describing its accuracy as near-human. We did not find a published benchmark report comparing its model against named competitors on a defined dataset  (4). That is a meaningful gap for a buyer trying to independently verify an accuracy claim before signing.

Channels, Compliance, and Use Cases

ConvoZen’s WhatsApp layer handles text, voice notes, images, video, and documents within one conversation thread, alongside voice and web chat. GreyLabs AI’s documented channel coverage centers on voice AI agents plus email analytics; we found no published documentation of WhatsApp or web-chat support.

On compliance, both platforms target the same pain point. GreyLabs AI markets full call analysis to replace manual audits that the industry typically caps under 5% of calls, applied to sales, collections, and renewal conversations. ConvoZen runs a comparable model across BFSI clients today: Lendingkart moved from auditing a single-digit percentage of calls to 100% automated QA and call scoring across 100+ compliance checkpoints, with a 20% lift in conversions. Jana Small Finance Bank used ConvoZen’s multilingual voice layer across 9+ Indian languages for pre-approved loan and collections outreach, with a 10% boost in resolution rate and 7% sales growth .

Which Platform Fits Your Business

• Consider GreyLabs AI if your contact center operations sit entirely within banking, NBFC, insurance, or broking, and a single-vertical roadmap matters more than channel breadth.
• Consider ConvoZen if you need BFSI-grade compliance monitoring alongside WhatsApp and chat coverage, or your group runs business lines outside BFSI that will eventually need the same conversational AI layer.
• Evaluate both on published benchmark transparency, language coverage for your specific customer base, and how pricing scales once you move past a pilot.

Conclusion

ConvoZen and GreyLabs AI are solving the same underlying problem, thin QA coverage and high compliance exposure in regulated, multilingual contact centers, from different starting points. GreyLabs AI’s advantage is depth in the single vertical it was built for. ConvoZen’s advantage is a published speech benchmark, a wider channel set including WhatsApp, and a platform already running across BFSI and adjacent industries. Which one fits depends on how narrow or broad your conversational AI needs are over the next two years. Book a demo with ConvoZen to see how the comparison holds up against your own call data.
