VoIP Speech Quality Simulation and Evaluation |
The paper first presents briefly the current ITU P.861 PSQM
Sun L, Wade G, Lines BL, Le Foll D, Ifeachor E
objective speech quality measurement algorithm. Then the influence of packet
loss and packet size on objective speech quality are simulated and analysed
on a VoIP simulation platform. The limitations and possible improvements of
the PSQM algorithm for use in VoIP applications are also given, together
with future work.
