Willoński Laboratory

Acoustics Based
Boutique Research Center

We study the voice, the pause, and the manner of service — and translate the acoustics of hospitality into protocols luxury brands can train, audit, and trust.

The Audit Read our research

Our service

Customer Experience Audit

We analyze the phone calls and in-person interactions of receptionists, hosts, and front-of-house professionals for the world's most demanding rooms — high-end hotels, luxury boutiques, fine dining. Voice, manners, politeness, composure: measured, trained, tested.

Vocal customer service

Recorded phone interactions are scored on warmth, clarity, latency, and recovery. Every line of the call surfaces in the report.

In-person service

Greeting, posture, tone and pacing on the floor — trained against the acoustic and behavioural standards of top-tier hospitality.
