Abstract
The description of system for full-duplex speech communication through Internet is presented. The frame-independent codecs at rates 4800, 9600 and 19200 bps were used for speech compression. The special protocol based on User Datagram Protocol (UDP) was used for data transmission. The paper consists from three parts. In the first part we briefly show the description of our codecs. In the second part we give the description of our protocol for organization of full-duplex speech link. In the third part we present our experimental system for speech communication which uses codecs and protocol from the first and second parts. Our developments were used in the “etalkRadio” project, which provides the organization of live shows in Internet. The detailed description of this project will be present on http://www.etalkradio.net.
