Cognitive load associated with speaking clearly in reverberant rooms [PDF]

Scientific Reports
Communication is a fundamental aspect of human interaction, yet many individuals must speak in less-than-ideal acoustic environments daily. Adapting their speech to ensure intelligibility in these varied settings can impose a significant cognitive burden.
