Appointment confirmations
Calls to confirm, remind, or reschedule: and writes the result back to your calendar. Cuts no-shows without tying up reception.
Operational tier · Voice
An AI voice agent that actually sounds human, in Greek.
It makes and takes phone calls in natural Greek or English: confirming appointments, qualifying inbound leads, running feedback calls. It understands replies, handles interruptions, and hands the call to a person the moment it should.
What does an AI voice agent do?
A voice agent holds a real phone conversation. It speaks in natural Greek or English, understands the caller's replies in real time, follows a goal (confirm an appointment, qualify a lead, collect feedback), and acts on the outcome, booking, logging, or transferring to a human with context. It runs outbound (proactive calls) and inbound (answering). Operational tier, built on Claude with a low-latency speech layer. Best for high-volume, bounded conversations where tone and Greek-language fluency matter. For pure inbound reception, see the Call Answering Agent.

FAQ
Questions about the Voice Agent (EL / EN).
Does the Greek actually sound natural?
Yes, with the current generation of speech models, Greek is fluent and natural, not robotic. We review real call transcripts in both languages during the eval phase and tune until tone and handling meet the bar before go-live.
What happens when it can't handle something?
It transfers to a human immediately (on request, on any out-of-scope topic, or on low confidence) and gives the person a spoken summary so the caller never has to repeat themselves.
Is it different from the Call Answering Agent?
They overlap but differ in focus. The voice agent is built for proactive, goal-directed conversations (outbound confirmations, qualification, feedback). The Call Answering Agent is built for inbound reception, answering your main line, triaging, and routing. Many clients run both.
How is this billed?
Build as a Spark engagement; running costs are telephony minutes plus Claude + speech usage, billed at cost. We size it on call volume during discovery.
