An Algorithm for Estimating the Delay of Telephony Speech

Stephen D. Voran

Abstract: This contribution is provided for informational purposes. It contains a description of an algorithm that has sucessfully been used to estimate the delay of telephony band speech. The algorithm features a coarse stage that uses speech envelopes and a fine stage that uses speech power spectral densities. Observations on the performance of the algorithm and its potential for extension beyond telephone band speech are offered. This algorithm is included in the Draft ANSI T1 Standard on Multimedia Communications Delay, Synchronization, and Frame Rate Measurement.
