What counts as a voice minute? Wall-clock duration of the LiveKit room — billed from agent-joined to call-end, rounded up to the nearest second. Ringing time is not billed.
Do you charge for noise cancellation? No. Self-hosted DTLN, GTCRN, and Hush noise suppression are included in the platform fee at no additional charge.
Can I bring my own LLM, STT, or TTS keys? Yes. BYOK is supported for all major providers. Provider costs bill to your account with the provider, not to us — we only charge the ₹1.5/min platform fee plus a small orchestration overhead.
Can I bring my own Twilio or Vobiz phone number? Yes. Native BYOK for Twilio and Vobiz SIP. Your number, your provider account, your provider invoice — we add ₹0/mo for BYOK phone numbers.
Is GST included? All ₹ prices on this page are pre-GST. GST (18%) is added on the invoice for Indian customers. For international customers, GST does not apply.
What is the cheapest voice AI in India? ThinnestAI's flat ₹1.5/min platform fee is the lowest published rate among Indian voice-AI platforms as of 2026. Combined with self-hosted Aero TTS (₹0/min platform-side TTS) and Vega STT (₹0/min platform-side STT for 22 Indian languages + 200+ worldwide), total cost drops below ₹2/min including provider pass-through for many call profiles.
