Relationships between Speech Intelligibility Measures for Sound Systems
A number of metrics exist to measure the potential speech intelligibility performance of a sound system. Most of these are derived from techniques developed for assessing natural speech intelligibility in auditoria rather than directly for sound systems whose acoustic characteristics and performance are highly frequency dependent. The paper compares measurements made on 81 sound systems that covered a wide variety of applications and acoustic environments. It was found that intelligibility metrics such as STI, RaSTI, C50 and C80 showed a high degree of inter correlation whereas surprisingly other measures such as RT60, EDT and % Alcons showed little or no correlation.
