Building Voice AI Agents in India: Why Sarvam Voice Agents

If you are building a voice agent for customers in India, Sarvam Voice Agents gives you the whole stack in one platform: speech recognition, reasoning, and speech synthesis built for Indian languages, plus telephony, testing, outbound campaigns, and analytics. Pricing is per minute, from ₹3.50 on pay as you go down to ₹3 on higher plans.

What you get in one platform

11 Indian languages plus English. Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, and Assamese, including code-mixed speech, alphanumerics, and proper nouns. See Overview.
Sarvam’s own models, self-hosted by Sarvam. Saaras v4 for speech recognition, Bulbul v3 and v4 for speech synthesis, and sarvam-105b-conversations for real-time dialogue, orchestrated for you. See Models.
Data residency in India. All data, including any PII, stays within India.
A run-time built for real phone calls. Interruptions and barge-in, language switching mid-call, voicemail detection, hold, long silences, and correct pronunciation of names and numbers are handled out of the box. See Run-time.
Telephony included. Rent an Indian number from Sarvam or bring your own provider. The same agent also runs on WhatsApp, web, and API.
Test before you go live. Run simulated test calls against scripted scenarios.
Outbound at scale and analytics. Run campaigns, then read call logs, analytics, and custom boards.
Build from your AI assistant. Connect Claude, Cursor, or VS Code over the MCP server to build, test, and deploy agents.

Build it yourself vs Sarvam Voice Agents

A production voice agent needs more than a speech API. Here is what you would assemble yourself, and what Voice Agents already includes.

You need	Build it yourself	Sarvam Voice Agents
Speech recognition for Indian languages	Choose and integrate an ASR provider	Saaras v4, included
Reasoning (LLM)	Choose, host, and prompt a model	`sarvam-105b-conversations`, routed automatically
Indian-language voices	Choose and integrate a TTS provider	Bulbul v3 and v4, included
Turn-taking, barge-in, orchestration	Run a framework such as LiveKit or Pipecat and tune it	Harness and run-time, included
Phone numbers and telephony	Contract and integrate a telephony provider	Rent a number for ₹59 per 30 days, or bring your own
Testing	Build your own test harness	Simulated test runs at ₹2 per run
Outbound campaigns	Build scheduling and dialling	Campaigns, included
Analytics	Build logging and dashboards	Analytics and boards, included
Data residency	Check each vendor separately	All data stays in India
Billing	Several vendors and invoices	One per-minute rate from one credit balance

What it costs

Plan	Voice agent rate
Pay as you go	₹3.50 per minute
Pro	₹3.25 per minute
Growth	₹3.15 per minute
Business	₹3.00 per minute
Enterprise	Committed-volume pricing, postpaid

Self-serve plans are prepaid from your credit balance. Enterprise is postpaid and invoiced monthly. For example, 10,000 minutes a month costs ₹35,000 on pay as you go. Telephony is billed separately.

When to use the APIs instead

Use Sarvam’s speech-to-text, text-to-speech, and chat APIs directly if you already run your own orchestration (for example LiveKit or Pipecat) and want full control of every component. For everything else, start with Voice Agents.
