Sarvam Language Coverage Multiplier

Sarvam's economics reward agencies that reuse a single voice agent build across many Indic languages. Text-to-speech covers 11 Indic languages and speech-to-text with diarization covers 12, so a Hindi appointment-booking agent can be redeployed for Marathi, Tamil, or Bengali clients by swapping language configuration rather than rebuilding dialogue logic. The Sarvam Voice Agent Starter is priced at $2,250 with 20h setup for one language; each additional language adds configuration hours, not a new build, which lifts effective margin per retainer. Usage sits on the client side: ₹30/hour for speech-to-text and ₹3 per 1,000 characters for TTS, so quote volume estimates before signing. A Pune agency serving clinics across three states can sell one agent architecture three times, then layer document digitization or dubbing as upsells. English-only Western clients see no multiplier, so screen for Indic-language call volume first.
