Voice Agents: Telephone Pre-qualification with AI.
A Voice Agent takes calls, records the inquiry, provides initial information, and forwards only qualified conversations to your team. No waiting customers, no lost calls, no time lost on standard questions.
Target Audience
Who is this for?
A good fit if...
- Your team handles 30+ calls daily and 40%+ are pure informational questions
- Callers hang up while on hold before anyone answers
- Calls outside business hours on weekends or evenings are lost
- You run a trade, facility management, service, or healthcare business
- You have no dedicated call center team, but still need to be reachable
Less suitable if...
- Your calls consist exclusively of highly complex individual consulting
- You receive fewer than 10 calls per day
- You already use an external call center with satisfactory results
Business Impact
Measurable Results for the Operator Hub
Voice Agents also answer evenings and weekends, summarize inquiries, and route them.
No ringing to nowhere, no frustrating hold music — immediate initial analysis.
Upon handover to a human, the summary is already in the system.
Model calculations based on real project values. Individual savings vary depending on the setup.
Architecture & Approach
The End-to-End Process: From Call to Data Integration
A robust process ensures the agent communicates naturally and reliably hands over when in doubt.
Understanding Speech (Speech-to-Text & NLU)
The customer calls. Their speech is transcribed in real-time. The AI (NLU) immediately recognizes the intent and extracts important data (like customer IDs).
Retrieving Knowledge (Information Retrieval)
If necessary, the system queries your internal knowledge base (RAG) in fractions of a second or checks status updates via API to prepare an informed response.
Answering & Speaking (LLM & Text-to-Speech)
Based on guardrails, the appropriate response is formulated and delivered via highly natural speech synthesis — including tiny pauses for more naturalness.
Action & Seamless Handover
If the inquiry becomes complex, the agent directly routes it to the right department — along with a summary of the conversation so far popping up on the employee's monitor.
Under the Hood
Technical Setup
So you can gauge what's really behind it — no black box promise.
Speech-to-Text (STT)
Real-time transcription of the call via models like Whisper or Azure Speech Services. Support for English with regional dialects. Latency under 500ms for a natural conversation flow.
Natural Language Understanding
Intent recognition via LLM (GPT-4o or comparable) with context-aware prompting. The agent doesn't just understand keywords, but the meaning of the statement — even with paraphrasing or incomplete sentences.
Dialogue Management
State-based conversation control with fallback logic. Defined escalation paths: If the agent is unsure, it forwards to a human — rather than guessing.
Text-to-Speech (TTS)
Natural-sounding speech output via neural TTS models (e.g., Azure Neural Voice, ElevenLabs). Configurable voice, tone, speaking rate, and pauses.
Telephony Integration
Connection via SIP Trunking or Cloud Telephony (Twilio, Vonage, etc.). Compatible with existing PBX systems — no hardware changes required.
Logging & Analytics
Every conversation is transcribed, tagged with intents, and evaluable in a dashboard. Recognition rates, call durations, escalation quotas — everything measurable and traceable.
Typical Stack
The concrete stack is tailored strictly to your existing systems and requirements. No vendor lock-in.
Frequently Asked Questions
Voice Agents — Concrete Answers
Does the Voice Agent sound natural?
Yes. Neural TTS models synthesize a natural voice with configurable tone. Most callers do not notice a difference from a human in the first few seconds.
What happens if the agent doesn't understand a question?
Defined escalation: The agent politely repeats, asks for rephrasing, and routes to a human representative after 2 attempts. No endless fallback loops.
Does this work with our telephone system?
In most cases, yes. The agent can connect via SIP Trunking to almost any PBX system — without replacing hardware. The KI-Erstanalyse checks compatibility.
How much does a Voice Agent cost?
Setup starts in the Starter Package from €2,900. Ongoing costs depend on call volume (telephony + API costs). Typically: €50–300/month for an SME handling 30–100 calls/day.
Can we customize the agent ourselves?
Yes. Texts, greetings, and simple flow logic are documented and accessible. Major adjustments (new workflows, system integrations) are handled within ongoing support.
