Sumeru Vaani
Vaani is Sumeru Systems' enterprise voice-synthesis platform, built Indic-first. It turns text into natural Indian-English, Hindi, Telugu, and Tamil speech - with an enterprise pronunciation dictionary, provider-neutral routing across best-in-class voice models, batch and personalized synthesis, and the governance an enterprise voice program needs.
An enterprise voice program, Indic-first.
From a single line of copy to thousands of personalized messages - Vaani makes voice that sounds right in the languages your customers actually speak, and keeps it governed.
Natural Indic speech
Production-grade text-to-speech for Indian-English, Hindi, Telugu, and Tamil - tuned for the names, code-mixing, and pronunciations that generic Western voices get wrong.
Enterprise pronunciation dictionary
One canonical lexicon - brand names, products, acronyms - drives every backend uniformly, so a word is said the same way on every voice model and in every message.
Batch & personalized synthesis
Generate thousands of personalized voice messages from a template plus your data - built for BFSI workflows like collections, KYC, and payment reminders.
Provider-neutral routing
Route each request across best-in-class voice models by latency, quality, cost, and language. Bring your own keys; the router is fail-open, so a degraded provider drops to the next-best tier instead of erroring.
Governance & spend control
Per-tenant budgets, usage analytics, and cost attribution - with cost quotes before you synthesize, RBAC, and per-tenant rate limits so spend never runs away.
Trust & data residency
Multi-tenant isolation, region-scoped audio artifacts, an immutable audit log, and SLA-backed native verification of Indic pronunciation.
Own the pronunciation. Route the rest.
Vaani separates what is said from how it sounds, then routes to whichever voice model fits - so pronunciation is consistent and you're never locked to one vendor.
Voice Intelligence Layer
Your enterprise dictionary feeds pronunciation (grapheme-to-phoneme) that resolves to canonical IPA phonemes. One lexicon entry then drives every backend the same way - so pronunciation stops being at the mercy of each vendor's mechanism.
Conditioning controls
Accent, emotion, and prosody ride on top of the phonemes as style controls, on the backends that support conditioning - so a message can sound calm and formal or warm and upbeat without changing the words.
Provider-neutral Voice Router
Every request is routed by latency, quality, cost, and language across the voice models you've configured. No vendor SDK shape leaks into your integration, and failover is automatic and fail-open.
Governed, auditable, and yours to control.
Voice at scale is a spend, security, and compliance surface. Vaani treats it like one from day one.
RBAC & SSO
Role-based access control across every privileged action, with SSO (SAML / SCIM) on the enterprise plan.
Budgets & spend governance
Per-tenant budgets, usage analytics, and cost attribution - plus a quote endpoint that prices a job before it runs.
Immutable audit & export
Every privileged action is written to an append-only audit log you can export to CSV for compliance.
Data residency
Region-scoped audio artifacts and strict tenant isolation, enforced at the data layer.
Bring your own keys
Use your own Sarvam, ElevenLabs, or Azure credentials - Vaani stays provider-neutral and never locks you in.
Native verification SLA
Human, native-speaker verification of Indic pronunciation offered as an SLA-backed deliverable, not a best-effort promise.
