AI Voice Agent
Software that answers phone calls with a natural-sounding voice, understands what the caller wants and executes actions (bookings, orders, transfers) without human supervision.
What is an AI voice agent
An AI voice agent is a program that picks up phone calls and converses with the caller using natural-sounding voice synthesis. It understands natural language via speech recognition + a language model (GPT-5, Claude), then responds and executes actions: books in calendar, takes orders, opens tickets, transfers to a human.
How it works technically
Standard 2026 flow: caller dials → voice orchestration platform (e.g. Vapi) receives audio via SIP/WebRTC → audio → transcript via speech recognition → AI model generates response → text-to-speech (e.g. ElevenLabs) synthesizes natural voice → audio plays back. Total latency: 400-1000ms per round-trip.
Use cases
- Automatic bookings for medical/dental clinics, salons
- Lead qualification for real estate agencies
- Tier-1 customer support for e-commerce and utilities
- Automatic order or delivery confirmations
- 24/7 answer for small businesses that can't afford night reception
Why it matters for businesses
In Romania, over 40% of calls to SMBs go unanswered outside business hours. An AI voice agent can handle those calls, qualify them, and often resolve them. Typical 2026 costs: €600-1,200/month for an SMB with 1,500-3,000 calls/month - about one third of a receptionist's salary.
