VAD Voice Activity Detection
{"Image DocumentName": "VAD Voice Activity Detection", "Image ImageDescription": "On average, about 35 percent of calls are silence. In traditional voice networks, all voice calls use a fixed bandwidth of 64 kbps regardless of how much of the conversation is speech and how much is silence. When VoIP is used, this silence is packetized along with the conversation. VAD suppresses packets of silence, so instead of sending IP packets of silence, only IP packets of conversation are sent. Therefore, gateways can interleave data traffic with actual voice conversation traffic, resulting in more effective use of the network bandwidth.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
