AI Voice Agent Cost Simulator
Model your AI voice agent costs by volume and simulate the call flow before you build

Before committing to a voice automation build, simulate the call. This tool lets you walk through a conversation as if you were the caller — testing how the AI handles questions, objections, off-script responses, and handoffs to live agents.
What Is a Voice AI Agent?
A voice AI agent is a phone bot powered by large language models and text-to-speech. Unlike the frustrating DTMF phone trees of the past, modern voice agents understand natural speech, hold context across turns, and hand off seamlessly to a human when needed.
Typical uses:
- Inbound call answering (after hours, overflow)
- Appointment reminders and confirmations
- Lead qualification calls for high-volume campaigns
- Collections and payment reminder calls
What the Simulator Tests
- Intent recognition — does the agent understand what the caller wants?
- Entity extraction — can it capture name, date, reason for call accurately?
- Interruption handling — what happens when the caller speaks over the agent?
- Escalation logic — does it hand off at the right moment?
- CRM write-back — does the transcript and outcome get logged correctly?
Platforms This Applies To
- Retell AI — production-grade voice agents with Twilio integration
- Vapi — developer-friendly voice AI
- ElevenLabs + custom LLM — for maximum voice quality
- Bland AI — high-volume outbound calling

Build Your Voice Agent
After simulating your flow, I can build and deploy a production voice agent with full CRM integration — the same architecture behind voice agents I've built for real estate, dental, and multilingual salon booking. Book a scoping call to get started.
