UDP
User Datagram Protocol (UDP) is one of the core protocols of the

Internet protocol suite

. Using

UDP, programs on networked computers can send short messages known as

datagrams

to one another.

UDP does not provide the reliability and ordering guarantees that

TCP

does; datagrams may arrive out of

order or go missing without notice. However, as a result, UDP is faster and more efficient for many
lightweight or time-sensitive purposes.

speech processing

wherein, the presence or absence of human speech is detected from the audio samples.
