SIZE IS 4msec AND CODING RATE IS 64Kbps. The name of the coding scheme is G.711. and we will run the simulation for 900 second by taking the packet size 1 and we will run the same simulation for the other one by making the speech activity disabled .
THIS SHOW THE GRAPH OF THE VOICE PACKET DELAY VARIATION FOR SPEECH ACTIVITY DETECTION ENABLED AND DISABLED ONES

HERE WE ARE CALCULATING THE THROUGHPUTVALUES OF THE ENABLED ONES AND DISABLED ONES THE THROUGHPUTÂ  GIVES US THE INFORMATION ABOUT THE DELIVERY OVER A COMMUNICATION CHANNEL. AND HERE WE ARE THE VALUES OF THE THROUGHPUTFROM THE GRAPH WE CAN UNDERSTAND THAT IF THE SPEECH ACTIVITY IS DISABLED THE USAGE OF THE BANDWIDTH IS HIGH AND THE PERCENTAGE OF THE OVERHEAD IS HIGH. DUE TO THIS THE STREGTH OF THE CONNECTION WILL GET WEAK. AND IF THE CONSUMPTION OF NTHE BANDWIDTH IS HIGH MEANS THENÂ  TRAFFIC IS ALSO HIGH WHICH LEADS TO THE CONGESTION. AND THE ROUTER CANNOT BEAR THE TRAFFIC AND AUTOMATICALLY THE LINK WHICH WAS THERE BETWEEN THE NODES WILL BE TERMINATED WHICH RESULTS IN THE LOSS OF DATA.DUE TO THIS QUALITY OF SERVICE IS REDUCED.

THE ABOVE GRAPH SHOWS THE UTILIZATION OF THE BANDWIDTH WHEN THE SPEECH DETECTION ENABLED AND DISABLED here the utilzation of the bandwidth for disabled packet is high and enabled packet is lowfrom this we can understand this  that by using the speech activity detection we can send the data at a faster rate in low time with the low bandwidth which results in the low traffic.
