Sanas vs. Krisp: No Comparison

If you're evaluating real-time speech AI for CX, you'll likely compare Sanas and Krisp. The largest operations in the world already ran that comparison on live calls, at scale, side by side. They chose Sanas. Here's why.

The Summary

The Market Already Ran This Evaluation

You don't have to take our word for any of this. The head-to-heads have been run, at a scale no lab test can match.

• Teleperformance deployed Sanas and Krisp simultaneously across 12,000 agents in India and the Philippines — the largest live side-by-side evaluation in the category. They chose Sanas.

   

• Enterprises including SoFi and Huntington Bank evaluated Krisp and came to Sanas. The pattern in those evaluations was consistent: output that sounded robotic, and support that was slow to respond when it mattered.

   

• 25 of the top 25 BPOs run Sanas in production.

   

• Comcast, UnitedHealth, CVS, Cigna, Citi, Capital One, Verizon, AT&T, IBM, UPS. The most demanding, most regulated, most scrutinized operations on earth put speech AI through procurement, security review, and live pilots - and chose Sanas.

As the market is proving, Sanas is enterprise-grade. Krisp is not.

Accent Translation: The OG

Sanas invented real-time accent translation and built it from the ground up, in house. We created the category and continue to lead it. We've run Accent Translation in production since 2021; Krisp entered the category in April 2025. That 4-year difference shows up in the product everywhere.

Coverage without enrollment. Sanas Universal Accent Translation covers every accent, every geography, out of the box. Zero enrollment: the model personalizes each agent's voice from the first call. Krisp requires an enrollment step per agent. At 500+ seats, with real turnover and quarterly program launches, that friction compounds into missed onboarding windows and stalled ramps. Enrollment is a demo-scale design decision that breaks at enterprise scale.

A real voice, preserved. Sanas uses zero-shot voice cloning. The agent sounds like themselves — same energy, same warmth, same person. Krisp's conversion flattens identity and expressiveness, and in high-stakes conversations where tone builds trust, that flattening costs you. Callers notice. CSAT notices.

Bidirectional across the platform. Agents are clearer to the callers, callers are clearer to the agents, on every product in the Sanas suite.

The published numbers settle the rest. Sanas beats Krisp on every published objective metric — NISQA, DNSMOS-sig, DNSMOS-bak, DNSMOS-ovr — with a +15.6% NISQA margin on background voice cancellation alone. Our benchmarks are published and independently verifiable. Krisp's accuracy claims are self-reported. 

Noise Cancellation is a Feature. Speech Enhancement is Embedded as a Pillar Across the Whole Product Suite.

Krisp filters background sound. That's the entire job, and it was state of the art a decade ago.

Sanas Speech Enhancement rebuilds voice and audio from the ground up, in both directions, at studio quality. It repairs what filtering can't reach: codec degradation, VoIP quality loss, packet issues, and the hardware chaos of work-from-home floors.

And it's load-bearing for everything you build next. Conversation intelligence, sentiment, auto-summaries — your entire AI stack runs on transcripts, and transcripts are only as good as the audio underneath them. Line degradation that noise cancellation ignores silently corrupts every system downstream. If you're investing in AI on top of your calls, filtered audio is a cracked foundation.

Language Translation: Compare Accuracy, Not Inventory.

Krisp advertises 60+ languages. Sanas supports 30+. A straight language count is not the right thing to compare; it’s more about performance. 

Sanas matches Krisp on latency and beats them on accuracy against independent industry standards — and beat OpenAI, Google, and Apple in the same testing. Auto language detection means the agent never waits, selects, or asks the caller what language they're speaking.

Most contact centers run one to three active language pairs. Sanas turns an English-speaking floor into a multilingual operation across 30+ languages: no bilingual hiring constraint, no interpreter queue, none of the 45–90 second connect times or per-minute interpreter fees. If your operation genuinely runs more pairs than that, send us your list and we'll confirm coverage on the spot.

Speech Intelligence: Real-time Compliance vs. A Report About What Happened in the Past

Krisp's analytics arrive after the call: summaries, coaching scores, knowledge retrieval. Useful for training. Useless in the moment that matters. Sanas provides the post-call layer too — and then goes where Krisp can't.

Sanas Speech Intelligence monitors every call in real time and flags compliance risk, script deviation, PII exposure, and escalation signals to the supervisor while the call is still live. A post-call report documents the violation. A live alert prevents it.

The architecture is what regulated industries actually require: everything on-device, PII redacted locally, no audio leaving the machine, no cloud dependency, no CCaaS integration — which means it deploys on BPO floors where the enterprise client controls the stack. In healthcare and financial services, where Sanas already operates at scale, one missed script deviation is regulatory exposure. Manual monitoring covers a fraction of calls. SI covers all of them.

Krisp has no answer to this. Post-call analytics and real-time compliance architecture are not the same category of product.

One Platform Is Built for Enterprise

Krisp serves consumers, prosumers, and workforce users from the same platform it sells to contact centers. Sanas was built for enterprise from the start, and the footprint shows it: 200+ of the world's leading enterprises, all 25 of the top 25 BPOs, a million devices across 40+ countries, four years in production.

You can see that focus in the product. On-device deployment options. An enterprise portal built for multi-tier hierarchies, so a BPO can manage multiple enterprise clients from one console. SSO, auto-activation, zero-touch provisioning. And deployment support with engineers who can be on-site — when something breaks in week one of a 1,000-agent pilot, response time decides whether the program survives. Our customers told us why they switched: they tried Krisp, and they needed a partner who would pick up the phone.

Building on Sanas

The Sanas SDK is a server-side speech AI foundation: it cleans and normalizes voice before it hits downstream systems, cutting word error rate without touching the rest of the stack. Telcos, CCaaS platforms, and teams building agentic voice AI use it for one simple reason — clean audio in, better results out of everything that follows.

Krisp shipped a translation SDK in February 2026. Sanas ships the infrastructure layer that the world's largest voice operations already run on.

It's Sanas. Hands Down.

Teleperformance ran Sanas and Krisp side by side across 12,000 live agents and chose Sanas — along with every top-25 BPO in the world. Sanas has run Accent Translation in production for four years with zero enrollment; Krisp entered the category in 2025 and still requires an enrollment step for every agent. Sanas Speech Enhancement rebuilds the call from the ground up, while Krisp's noise cancellation filters background sound and stops there. In Language Translation, Sanas beats Krisp on accuracy at matching speed — and beat OpenAI, Google, and Apple in the same testing. Sanas Speech Intelligence flags compliance risk while the call is still live; Krisp delivers a report after it ends. And underneath it all, Sanas is a platform built for enterprise from day one — 200+ enterprises, a million devices, 40+ countries — with an SDK for anyone building on top. The benchmarks are published. The numbers are public. Four years in, it's no longer a debate.
