Real-time AI voice for live conversations

Voice agents that listen, understand, and respond in natural Indian languages — for customer support, sales, and interactive applications.

Conversational voice agents

Deploy AI voice agents that engage in real-time dialogue with your customers. Natural turn-taking, interruption handling, context awareness across long conversations. Available on phone lines, web widgets, and in-app SDKs. Multi-language: agents can switch languages mid-conversation based on caller preference.

Real-time voice API

Sub-200ms latency from text to audio for live streaming. WebSocket and gRPC endpoints for high-throughput integration. Streaming text-to-speech delivers audio in chunks as it's generated — no wait for full-sentence completion. Ideal use cases: live translation, accessibility tools, voice AI products, gaming NPCs.

Customer support voice AI

Replace or augment your call center with AI voice agents. Handle Tier-1 queries automatically (order status, account info, common troubleshooting). Escalate complex issues to human agents with full context handoff. Available 24/7 in every supported Indian language. Integrates with Freshdesk, Zendesk, Salesforce Service Cloud, and Zoho Desk.

★★★★★
We deployed a Hindi voice agent to handle Tier-1 support for our lending product. It handles 68% of calls end-to-end without needing a human. Our human agents now only handle escalations — higher-value work, better job satisfaction, lower attrition. Nobody talks about this second-order benefit.

Common questions

Frequently asked

What latency can I expect for real-time voice?+
Sub-200ms first-byte on Enterprise plans, sub-400ms on Pro. Latency depends on your integration architecture and network — we provide latency budgets during discovery.
Can the voice agent switch languages during a call?+
Yes. Agents detect language switches automatically or on explicit user request. A caller can start in English and switch to Hindi mid-conversation — the agent follows seamlessly.
How does escalation to a human agent work?+
Configure escalation triggers (specific keywords, sentiment thresholds, or user request). On trigger, the call transfers to your existing call center with full conversation context passed via API.
