Speech coding and compression
Webdissimilar speech coding forma ts, promising results show that the proposed technique may achieve homogeneous re-sults with different speech compression algorithms. With a database of 14 speakers, speaker recognition experiments show an accuracy close to 100% after the analysis of 30 seconds of active speech for most of the considered speech WebSpeech compression is the process of compressing a speech signal to reduce its size for easy transmission. This paper investigates two techniques to compress the speech signal and reconstruct...

Much of the later work in speech compression was motivated by military research into digital communications for secure military radios, where very low data rates were used to achieve effective operation in a hostile radio environment. At the same time, far more processing power was available, in the form of VLSI circuits, than was available for earlier compression techniques. As a result, modern speech compression algorithms could use far more complex techniques tha… WebSep 12, 2003 · Traditional speech and audio coding and compression will remain important even as bandwidth increases dramatically to the home, to the office, and in wireless …
