Operating inputs
Adjust call volume and agent speech share to estimate model cost only.
Assumptions
- Korean speech estimate: 250 chars/min
- AI talk ratio: 50%
- FX: 1 USD = ₩1,370
- Model pricing uses each voice's cost_per_1k_chars value.
agent minutes/call = average call length × AI talk ratio
chars/call = agent minutes × 250
annual chars = chars/call × annual calls
annual USD = annual chars ÷ 1000 × $/1k
