Prompts
Prompts guide the agent’s decisions, defining how it interprets requests, responds, and selects actions.

The call flow
Two innovative processing pipelines for calls.
VoiceBooker supports both a modular pipeline using STT, text-based LLMs, and TTS, and a direct speech-to-speech pipeline.
Pipeline 1 · modular speech processing
Modular pipeline: STT → LLM → TTS

Pipeline 2 · direct speech processing
Speech-to-speech.
Audio is understood directly and returned as a spoken response, without separate STT and TTS steps.

The layer that connects it all
Innovative
Voice Engine.
It connects speech, prompts, knowledge, and actions, then coordinates what happens next in the conversation.
Speech, context, and actions working together.
Real-time workflows
Callers can interrupt the agent at any time, creating a natural, human-like conversation flow. If a transaction is interrupted midway, the agent cancels it, retains the conversation context, and continues in response to the caller’s new input.
Flexible models
Combine speech, voice, and LLM models from different providers to tailor the architecture to your use case.
Node.js engine
The powerful Node.js engine connects seamlessly to backend systems. State-based workflows reduce hallucinations, while natively executed code enables highly precise actions.
