The proposed methods aim at greatly reducing the computational requirements while maintaining good measurement accuracy. The delay measurement is based on the cross correlation; the computation reduction is achieved by using either downsampled speeches or sparse speeches for the two methods, respectively. The echo-path loss is also measured by using the obtained delay information. The performance under codec distortion, packet loss, noise, and double talk conditions is examined through simulations and real field measurements. The results show that the proposed methods are effective and accurateenDistortion measurementSpeechPage description languagesNonlinear distortionDelay estimationInternet telephonyLoss measurementPerformance lossCodecsAdded delayNonintrusive Measurement of Echo-Path Parameters in VoIP EnvironmentsArticle
