Which to choose
The right fit depends on what you need
Choose Vocily if
- You are below Sarvam's volume tiers: Vocily starts at ₹3.10/min against their ₹3.50 pay-as-you-go rate.
- You want Sarvam's speech models for one language and a different voice or LLM for another, inside the same agent.
- You want the agent to remember each caller across phone calls and WhatsApp, and to fall back to another speech or language model if one fails mid-call.
- You want 10 concurrent calls without a monthly fee or a volume commitment.
Choose Sarvam if
- You need a vendor with ISO 27001 and SOC 2 Type II reports today.
- You run more than 65,000 minutes a month and want the ₹3.00/min end-to-end rate from one vendor.
- You want simulated test calls graded by an AI judge, branching multi-state flows, and SQL analytics boards.
- Your numbers are on Exotel, Twilio or Tata Tele Smartflo, or you need a do-not-call list on campaigns.
