Interview: sQLEAR a novel voice quality predictor for 4G and 5G voice services

sQLEAR is a network centric voice QoE algorithm, based on Machine Learning (ML) technology and tailored for drive testing. It’s a cost-efficient optimization solution focusing on real network issues rather than device rooted problems. By creating a huge amount of test and learning data we get about 96% prediction accuracy from the ML algorithm. sQLEAR is developed based on ITU-T P.565 and validated by our customers.
