    How a call is processed.

    From the incoming call to the spoken response. Every stage is measurable, monitorable and replaceable.

    05

    Monitoring

    Logs & analytics

    Five building blocks, one agent.

    Modular architecture: every component has a defined job and can be swapped out.

    01

    Incoming call

    The agent gets its own number and is integrated into your existing phone system without any hardware changes.

    02

    Speech-to-Text

    Neural speech recognition converts audio to text in real time, even with dialects and background noise.

    03

    LLM processing

    Understands intent, holds context-aware conversations and makes decisions on its own, including RAG knowledge and tool execution (calendar, CRM, APIs).

    04

    Text-to-Speech

    Natural speech synthesis with emphasis, pauses and emotional nuance, controllable through the system prompt.

    05

    Monitoring

    Transcripts, intents, actions and sentiment: complete logging of every call.

    The Orchestration Layer.

    The central architecture component that connects all individual systems. Without it, the building blocks would be isolated tools. With it, they become an agent that can act.

    Full control over latency, data flow, model selection and compliance.

    • 01

      Control center

      Coordinates the data flow between all components in real time.

    • 02

      Latency < 1 second

      Parallel processing, intelligent caching, predictive loading.

    • 03

      Always the latest market-leading models

      We continuously integrate the best AI models from the market leaders, GDPR-compliant within ScaleTalk.

    • 04

      Decision logic

      Decides in milliseconds: answer, RAG query, tool or call transfer.
