The world is not made of words.
The last 4 years of AI have been a triumph of distillation:
take the world, reduce it to tokens, predict the next one.
It built ChatGPT. It will not build a voice that actually understands you.

Text isn't enough

Language is what's left after the world has been compressed into symbols. Every voice carries everything that compression throws away — the warmth behind a smile, the hesitation before a hard truth, the room behind the speaker, the rhythm underneath the language. Speech is texture. Text is residue.

A different foundation

Our Latent Speech Model learns meaning in a continuous latent space — the shape of speech itself, not its transcript.

Built to expand

One foundation for any other downstream speech tasks like Text-to-Speech, Speech-To-Text, Speech Translation, Speech-to-Speech, etc. Each ability is a decoder off the same latent core.

Vaani is a full stack company
We own the models, infrastructure and the deployments.

Models

We build models the way the brain seems to: a single foundation that learns the shape of speech in a latent space — and then specialist decoders that turn that foundation into specific abilities.

  • 👄Voice synthesis (Active)
  • 👂Voice Recognition (In the build)
  • 🧠Voice Reasoning (In the build)

Infrastructure

From our inhouse C++ based fastest orchestration to Flash-Attention 4 specific traning on GPUs with lower memory bandwidth and lesser transistors. Infrastructure engineering is at the heart of Vaani.

  • 🧬Self-evolving Intelligence
  • 🔀Hybrid inference
  • Sub-600 milliseconds P90 latency

Products

Different ways to use the power of Voice AI. From white-glove enterprise deployment to GUI to a single API key. As we own the stack, we control the costs and the performance.

  • 📉Reduction in Costs over time
  • 🎯Better RCA and Performance
  • 🔒Complete sovereignty, guranteed.

One latent foundation.
Many ways to speak it.

Why Vaani, specifically?

All features

Multilingual at the foundation, not at the edges.

ElevenLabs and Cartesia trained on English first and fine-tuned the rest. Sarvam built Indic-only. We built a foundation that's natively multilingual — code-mix included — from day one.

We own every layer between the model and the phone line.

148,000 lines of C++ orchestration, written before the tooling existed. No vendor seams, no stitched latency. When something needs to be faster, we change the engine — not a ticket queue.

20× less data to match category benchmarks.

Our EDL + DAIL training approach learns the structure of speech, not just its statistics. That efficiency is what makes low-resource languages viable — and what makes the next ten languages cheap.

Research-first, deployed in production.

The same latent foundation we publish benchmarks on runs live collections calls for banks. The research isn't a lab exercise — production is the proof it works.

Evidential Speech Learning: Why non-english models are still sub-standard and how to bypass it!

We pre-training a speech model with number of evidences as the core idea. In every language corpus of the world - the dearth of good speech data and its mapping is a major bottleneck to train the models matching or surpassing the quality standards set by ElevenLabs. Vaani's model architecture holds the break-through. Read the study →
