Speech Intelligibility and Audio Monitoring in OTT

The paper details ways of controlling speech intelligibility in OTT and broadcast production, primarily based on a new metric, Loudness to Dialog Ratio (LDR), and on calibrated sound monitoring at a moderate listening level. Principles of Loudness normalization are described; as is a study to define and quantify LDR for use in broadcast and OTT. Findings may be applied during mixing or dubbing, used for default settings in NGA delivery, and in automated QC as a key machine learning parameter. The article is facts-based and free of commercial bias.
