Ishita uses Sarvam AI's Bulbul v3 — a voice engine trained specifically on Indian English and Hindi, not an American call center model. When a caller breaks into Hindi mid-sentence, she follows. When a corporate guest speaks formally, she matches that too. She doesn't sound like a robot. Most callers don't realise.
