| Summary: | Improving voice quality over wireless communication becomes a demanding
feature for social media apps like facebook, whatsapp and other
communication channels. Voice-over-internet protocol (VoIP) helps us to
make quick telephone calls over the internet. It includes various mechanism
which are signaling, controlling and transport layer. Over wireless links,
packet loss and high transmission delay damage voice quality. Here VoIP
quality will be measured by three main elements which are signaling
protocol, audio codec and transport layer. To improve the overall voice
quality, we need to combine these three elements properly to get the best
score. Otherwise perceptual speech quality will not be the right tool to
measure the voice quality. Here we will use Mean Opinion Score (MOS) for
calculated jitter values and end to end delay. At the end, best combination of
audio codec & signaling protocol produced the quality speech. |
