Log in with your Sarvam account and open **Voice Agents** from the left menu to start building: #### [Open Voice Agents](https://platform.sarvam.ai/samvaad) Log in at platform.sarvam.ai/samvaad to create, deploy, and manage your agents. ![The Sarvam platform home screen. The left navigation lists Sarvam API, Voice Agents, Sarvam Creative, and Sarvam Doc AI; the main area shows product cards and a credits balance.](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/sarvam-api-docs.docs.buildwithfern.com/3124f05358412ac8e5259ebb2904cf6ef18c1a6dffa1928330a5b8b3219e0ea4/voice-agents/images/wheretofind.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260730%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260730T094503Z&X-Amz-Expires=604800&X-Amz-Signature=e8b9bab213b958ec978a52940caa53ce01eec5bba6e939ee325f80dd2dfe6065&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject) ## What it is Voice Agents is a platform for building, deploying, and monitoring **conversational agents (voice and text)** that let you talk to your customers at scale. Author an agent once and run it across the channels your customers already use, in 10 Indian languages and English. #### [Build](/conversations/build/overview) Design agent behavior, voice, language, tools, and conversation flow. #### [Deploy](/conversations/deploy/overview) Test in test agent, connect telephony, and go live on phone numbers. #### [Monitor](/conversations/monitor/overview) Track analytics and build custom boards for agent performance. ## What is a conversational agent? A conversational agent is software that talks with your end customers in natural language to get something done: answer a question, collect information, complete a transaction, or hand off to a human. Instead of navigating a menu or filling a form, the customer simply speaks or types, and the agent responds. Agents come in two primary modalities: | Modality | The customer… | How it works | | --------- | ------------------ | -------------------------------------------------------------------- | | **Voice** | Speaks and listens | A real-time ASR → LLM → TTS loop (see [Architecture](#architecture)) | | **Chat** | Types and reads | Text in, text out, with support for richer message types | The same underlying agent design (prompts, tools, knowledge, and variables) powers both. What changes is how the customer sends and receives turns, and which [channel](#channels) the agent runs on. ## Languages Agents operate across **10 Indian languages and English**: Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, and Odia, plus English. They can also handle code-mixed speech, alphanumerics, and proper nouns. Additional languages, including Assamese, Urdu, and Konkani, up to the full IN22 set of 22 scheduled Indian languages, are also available on the **enterprise tier** on request. ## Channels The same agent can be deployed to multiple channels: | Channel | Use it for | | ------------------------ | ------------------------------------------------------------ | | Telephony | Inbound and outbound phone calls | | WhatsApp | Chat over WhatsApp | | Web | A voice or chat widget embedded in your site | | API | Driving the agent programmatically from your own application | | SDK (agent as a service) | Embedding the agent into your application with our SDKs | ### Availability by agent type Voice agents are generally available on every channel except WhatsApp. Text agents, and voice agents on WhatsApp, are available to enterprise customers on request. | Channel | Voice agent | Text agent | | ------------------------ | :---------: | :--------: | | Telephony | | | | Web | | | | API | | | | SDK (agent as a service) | | | | WhatsApp | | | Generally available   ·   Enterprise, on request This documentation currently covers **voice agents**. Text agents and the enterprise-only options above aren't covered here yet. To enable them, [contact us](https://www.sarvam.ai/contact-us) about the enterprise plan. ## What you can build Common agents teams run on Voice Agents: * Appointment booking and reminders * Payment follow-ups and collections * Cart recovery * Inbound customer support * Marketing communication and lead generation Many teams use Voice Agents as an alternative to traditional CRM-driven outreach: they engage users directly through conversation, drive strong outcomes, and capture rich feedback from the conversational data itself. Agents can call your systems, CRM, core banking, payments, and others, through [tools](/conversations/build/tools), so they can act, not just answer. ## Self-hosted models Every model in the Voice Agents stack, speech recognition, reasoning, and speech synthesis, is **self-hosted by Sarvam** rather than called out to a third-party provider. That gives you: * **Data residency in India**: all data, including any PII, stays within India, which matters for compliance and data-protection requirements. * **Lower latency**: no external network hops between stages, which matters most for real-time voice. * **Higher reliability**: the stack doesn't depend on the uptime or rate limits of an outside API. * **More control over quality**: the models are tuned and versioned together as one stack. See [Models](/conversations/build/models) for the models behind the stack. ## Build your first agent in 5 minutes Follow the [Quickstart](/conversations/quickstart) to create a voice agent, test it in test agent, and place your first call.
