The Speech Intelligibility Meter will be available as a software license option for TMxCore

The Netherlands - RTW has announced a major new addition to its flagship TMxCore audio metering platform: the Speech Intelligibility Meter.

The new meter helps broadcast and professional audio engineers identify and address speech intelligibility issues in film, television, streaming, and live production. Whether it is unclear dialogue in a drama series, competing background music in reality TV, or crowd noise overwhelming commentators in a sports broadcast, the RTW Speech Intelligibility Meter offers an intelligent, AI-powered solution for identifying speech intelligibility challenges in any production environment.

Developed in close cooperation with Fraunhofer IDMT in Oldenburg, the meter uses objective, AI-based speech intelligibility to deliver an easy-to-interpret measurement of how clearly spoken content is perceived. This empowers engineers to quickly balance dialogue, effects, and music, keeping dialogue intelligible while also improving the listening experience for audiences.

“At RTW we have a long tradition of making complex audio measurements accessible and useful to working engineers,” said Thomas Valter, director of product management & marketing, RTW. “With the Speech Intelligibility Meter, powered by Fraunhofer IDMT’s AI technology, we give broadcasters and post-production professionals an objective tool to ensure dialogue always remains clear and engaging – eliminating the guesswork from critical mixing decisions.”

“Fraunhofer IDMT is committed to developing practical technologies that solve real-world challenges,” said Prof. Dr. Jan Rennies-Hochmuth, group leader for personal hearing systems at the Branch for Hearing, Speech and Audio Technology at Fraunhofer IDMT. “Through our partnership with RTW, this innovation now reaches audio engineers worldwide as a trusted, easy-to-use tool.”

The Speech Intelligibility Meter will be available as a software licence option for TMxCore and showcased at IBC 2025, booth 8.D75.
