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). Two things govern the outbound side in Europe: it calls only numbers you hold consent for, because an automated call is a stricter legal category than a human one, and it says it is an AI in its opening line, as Article 50 of the EU AI Act has required since August 2026. Operational tier, built on Claude with a low-latency speech layer. For pure inbound reception, see the Call Answering Agent; for building the consent list in the first place, see the AI Sales Agent.

How the Voice Agent (EL / EN) actually works.
| Job-to-be-done | Hold goal-directed phone conversations at volume, in Greek or English, and act on the outcome |
| Tier | Operational (departmental flow) |
| Underlying model | Anthropic Claude + low-latency speech-to-text / text-to-speech |
| Trigger | Outbound: scheduled call list, filtered to numbers with recorded consent · Inbound: incoming call to a number |
| Inputs | Call objective + script guardrails, consented contact list (outbound), knowledge base, calendar/CRM access |
| Consent gate | Fail-closed. No outbound number is dialled without a consent record attached, with its source and timestamp. Unverifiable records are blocked, not assumed. |
| AI disclosure | Discloses that it is an AI in the opening line, per EU AI Act Article 50 (applicable since 2 August 2026). Not configurable off. |
| Tools available | Telephony (SIP), calendar, CRM read+write, live transfer, SMS follow-up |
| Autonomous decisions | Conversation flow, when to confirm/repeat, when to transfer, follow-up channel |
| Escalation rules | Caller asks for a human → immediate transfer · Out-of-scope request → transfer · Low confidence / distress detected → transfer with context |
| KPIs measured | Calls handled, completion rate, transfer rate, average handle time, booking/qualification rate, CSAT |
| Eval suite | 22 test cases incl. accent/interruption handling and transfer triggers. Greek + English transcripts reviewed. |
What it does
The work it takes off your team.
Lead qualification
Calls inbound enquiries, asks your qualifying questions, scores the lead, and books the fit ones onto a human's calendar.
Feedback calls
Runs post-service or post-purchase calls, captures structured feedback and sentiment, flags unhappy customers for follow-up.
Natural Greek
Speaks fluent, natural Greek (and English): handles interruptions, clarifications, and informal phrasing, not a rigid IVR tree.
Live handoff
Transfers to a person the moment the caller asks or the request goes out of scope: with a spoken summary so the human starts informed.
Logging
Every call transcribed, summarised, and logged to your CRM with outcome and next action. Full audit trail.
Consent gate
Outbound dials only where a consent record exists, with source and timestamp. An automated call is a stricter legal category than a human one, so the gate fails closed rather than guessing.
Declares itself
Says it is an AI in its opening line, as the EU AI Act has required since August 2026. On a call the person agreed to receive, saying so disarms people faster than pretending would.

What it looks like in practice
A typical run.
- Morning, Agent works the day's confirmation list: calls tomorrow's appointments, confirms or reschedules, updates the calendar.
- Throughout the day, Answers overflow inbound calls, qualifies enquiries, books the fit ones, transfers anything out of scope.
- Afternoon, Runs feedback calls on last week's completed jobs, captures structured sentiment.
- End of day, Sends a digest: calls made/taken, confirmations, bookings, transfers, unhappy customers flagged.
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.
Can it make cold calls to people who have not consented?
No, and that is a deliberate limit rather than a missing feature. An automated call, where a system dials and holds the conversation without a human, is treated more strictly in European law than a person picking up a phone: it needs express prior consent, and in Germany there is no business-to-business exception at all, with the existing-customer exception covering email but not calls. So the outbound list is filtered to numbers with a consent record before anything is dialled. If you need to reach businesses that have not consented yet, that first approach is made by a person, and the AI Sales Agent is the system that researches them, prepares the briefing and builds the consent list the voice agent then works.
Does it have to say it is an AI?
Yes. Article 50 of the EU AI Act, applicable since 2 August 2026, requires that a person be told they are interacting with an AI system unless that is already obvious. Our agent discloses it in the opening line and we do not offer a version that hides it. In practice it costs less than people expect: on a call the recipient has already agreed to receive, saying so plainly tends to lower their guard rather than raise it.
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.
