Speech coding is an application of data compression to digital audio signals containing speech. Speech coding uses speech-specific parameter estimation...

Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital...

Excitation Coding, abbreviated as HVXC is a speech coding algorithm specified in MPEG-4 Part 3 (MPEG-4 Audio) standard for very low bit rate speech coding. HVXC...

Unified Speech and Audio Coding (USAC) is an audio compression format and codec for both music and speech or any mix of speech and audio using very low...

A speech code is any rule or regulation that limits, restricts, or bans speech beyond the strict legal limitations upon freedom of speech or press found...

Code-excited linear prediction (CELP) is a linear predictive speech coding algorithm originally proposed by Manfred R. Schroeder and Bishnu S. Atal in...

of human behavior, which is speech acts. A basic definition of speech code by sociologist Basil Bernstein is, "...a coding principle is a rule governing...

source coding: encoding is done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for...
