A real-time voice agent that answers the phone, understands the caller, and gets work done on the call — in every major European language. Under the hood it's a streaming, low-latency pipeline engineered end to end by 23 Solutions. Here's how it works.
Every conversation runs one tight loop, many times a second, for the length of the call. No single step is exotic — the craft is in the seams between them: the latency budget, the turn-taking, and the recovery when a caller does something the script never imagined.
Calls connect over standard SIP telephony with sub-second pickup — inbound or outbound, many at once. No queue, no voicemail, no missed opportunity.
Streaming speech-to-text transcribes the caller as they speak, with voice-activity detection tracking the exact moment a thought ends — so the agent responds in the natural rhythm of a conversation.
A language model reads intent in context — capturing the details a booking needs, remembering what's already been said — steered by a per-industry playbook and strict guardrails.
Through live function calls it checks real availability, books the slot, creates the lead, or routes the request — acting on the business's actual calendar and CRM, never a canned script.
Low-latency speech synthesis answers back with natural prosody, and handles interruptions gracefully — callers can barge in mid-sentence and still be understood.
Conversation dies in the pauses. We account for every millisecond across the pipeline — streaming and overlapping each stage — so replies land in the rhythm of natural speech, barge-in included.
One system recognises, reasons, and replies across every major European language — and can switch mid-call — without a separate build per market.
The agent stays on-task where it matters: clinics and legal callers receive information, never advice; regulated and sensitive verticals carry the right tone and limits by design.
Real businesses route their front desk to this. It's built for 24/7 uptime, high call concurrency, graceful degradation, and a clean hand-off to a human when that's the right call.
A booking only counts when it lands in a real calendar against real availability. VocaAI reads and writes live business systems, with confirmations the caller can rely on.
Voice AI succeeds or fails on unit economics. We tune the pipeline to keep a spoken minute cheap enough to build a durable, profitable product around.
