Automatic Sound Signals Quality Estimation

This document discusses automatic sound signal quality estimation. It describes the basic components of an estimation system, including test signals, synchronization, and analytical modules. It also reviews existing quality estimation methods like AI, SII, STI, and C50. The proposed system generates test signals, synchronizes original and processed signals, and analyzes similarity to provide objective quality metrics. Potential applications include estimating quality of voicemail transmission, IP calls, and cellular/satellite connections. Further development areas are also outlined.
