An Investigative Proposal On Speech Coding For VoiP Communication

• Broschiertes Buch

Produktbeschreibung

The work embodied in this is based on Data security. This is one of the major concerns for digital data as well as voice transmission through non-privatized networks. Hence, a significant amount of research work is needed to provide reliable and secured data/voice transmission. The CS-ACELP algorithm based G.729 codec is standardized as voice codec by ITU-T for multimedia and Voice over Internet Protocol (VoIP) applications. The encoding scheme for CS-ACELP speech codec described in this work provides on-fly security for the encoded data for a secured speech transmission. This method is based on the periodically changing the track sequence of fixed code-book index for every 100 ms speech samples sampled at a rate of 8000 samples per second and also, adapting a new technique to encode the fixed code-book index. This book presents efficient way of providing data security for G.729 codec.
