speech compression technique
1Compression artifact — Original image, with good color grade Loss of edge clarity and tone fuzziness in heavy JPEG compression A compression ar …
2Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… …
3Audio compression (data) — For processes which reduce the amount of time it takes to listen to and understand a recording, see time compressed speech. Audio compression is a form of data compression designed to reduce the size of audio files. Audio compression algorithms… …
4Time-compressed speech — is a technique used, often in advertising, to make recorded speech contain more words in a given time, yet still be understandable. Contents 1 History 2 Methods 3 Advantages 4 Disadvantages …
5Lossless data compression — is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be… …
6Dynamic range compression — This article is about a process that intentionally reduces the dynamic range of audio signals. For similar reductions caused by circuit imperfections, see Gain compression. For processes that reduce the size of digital audio files, see Audio… …

8Huffman coding — Huffman tree generated from the exact frequencies of the text this is an example of a huffman tree . The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 bits, as opposed of 288 bits if 36… …
9Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… …
10Index (search engine) — Search engine indexing collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and… …
