speech coding
1Speech coding — is the application of data compression of digital audio signals containing speech. Speech coding uses speech specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression …
2Speech processing — is the study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation whereby speech processing can be seen as the intersection of digital signal processing and natural language… …
3Speech Code Theory — refers to a framework for communication in a given speech community. As an academic discipline, it explores the manner in which groups communicate based on societal, cultural, gender, occupational or other factors.A basic definition of speech… …
4Speech synthesis — Stephen Hawking is one of the most famous people using speech synthesis to communicate Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented… …

6Linear predictive coding — (LPC) is a tool used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model. It is one of the most… …
7Harmonic Vector Excitation Coding — Harmonic Vector Excitation Coding, abbreviated as HVXC is a speech coding algorithm used in MPEG 4 standard for very low bit rate speech coding. HVXC supports bitrates of 2 and 4 kbit/s. Technology HVXC is a parametric speech codec, which in… …
8Joint source and channel coding — In information theory, joint source–channel coding is the encoding of a redundant information source for transmission over a noisy channel, and the corresponding decoding, using a single code instead of the more conventional steps of source… …
9Harmonic Vector Excitation Coding — (HVXC) ist ein auf die Übertragung von Sprache optimiertes Verfahren zur Kompression von Audiodaten. Trotz sehr geringer Bitraten sind HVXC kodierte Daten für die Übermittlung von Sprache in einer akzeptablen Qualität geeignet. Eingesetzt wird es …
10Linear Predictive Coding — (LPC) ist ein in der Audio Signalverarbeitung und Sprachverarbeitung unter anderem für die Audiodatenkompression und Sprachanalyse verwendetes Verfahren, das mittels Audiosynthese arbeitet. Dabei wird der Stimmtrakt (des Menschen) modellhaft… …
