We are pleased to congratulate all delegates who successfully completed the Designing for Speech Intelligibility (DSI) training course, held on 25 June 2026 at Audiologic’s headquarters in Harlow.

Presented by Tony Stacey, a specialist in speech intelligibility and voice alarm system design, the course provided delegates with a comprehensive understanding of the principles and practical application of speech intelligibility in public address and voice alarm systems.

The course covered the key principles of speech intelligibility, including the factors that affect STI performance, system design techniques, measurement and verification methods, and the application of current standards and best practice.

Following both the training and assessment, all delegates successfully passed the course, proving their understanding of this important and highly specialised subject.

We would like to thank Tony Stacey for delivering another engaging and informative course, and to Audiologic for hosting the event and providing excellent facilities and hospitality.

Demand for specialist training in speech intelligibility continues to grow as organisations look to design and commission systems that meet the highest standards of performance and compliance. This course forms part of ISCVE’s ongoing commitment to supporting professional development across the sound, communications and audiovisual industries.
