Voice compression
Encyclopedia
Voice compression may mean different things:
- Speech encodingSpeech encodingSpeech 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 algorithms to represent the resulting...
refers to compression for transmission or storage, possibly to an unintelligible state, with decompression used prior to playback.
- Time-compressed speechTime-compressed speechTime-compressed speech is a technique used, often in advertising, to make recorded speech contain more words in a given time, yet still be understandable.-History:...
refers to voice compression for immediate playback, without any decompression (so that the final speech sounds faster to the listener).
- Audio level compressionAudio level compressionDynamic range compression, also called DRC or simply compression reduces the volume of loud sounds or amplifies quiet sounds by narrowing or "compressing" an audio signal's dynamic range...
