Voice Agent Pricing Calculator - Compare voice agents API costs and simulate latency

by
The Voice Agent Pricing Calculator helps developers compare STT, LLM, and TTS providers to build optimal voice AI agents. Calculate realistic per-minute costs and visualize end-to-end latency across the entire voice-to-voice pipeline.

I built Voice Agent Pricing Calculator to solve a real problem: understanding the true costs and latency of building voice AI agents. The calculator shows detailed breakdowns of STT, LLM, and TTS costs, with accurate latency visualization for each component in the voice-to-voice loop. Engineers can now see exactly where bottlenecks occur and make better provider choices. Try different combinations of GPT-4o, Claude, Gemini, Deepgram, ElevenLabs, Cartesia and more to find your ideal stack. Would love your feedback on what else would be helpful for voice AI developers!
