A REVIEW OF DIFFERENT SPEECH CODING METHODS

Speech coding is a lossy type of coding and hence the output signal does not exactly sound like the input. Speech coding is useful for long distance communication, message encryption and quality of speech. Speech coding has been major issue in the area of digital speech processing and telecommunication fields. Keywords: Speech coding, LPC, Sub band, MELP

©Yao Wang, 2006 EE3414: Speech Coding 13 Speech Coding • Speech coders are lossy coders, i.e. the decoded signal is different from the original • The goal in speech coding is to minimize the distortion at a given bit rate, or minimize the bit rate to reach a given distortion • Figure of Merit

research examines the effectiveness of VoIP speech coding in mitigating audio adversarial attacks when compared to more primitive forms of audio preprocessing and shows that an ensemble defense in tandem with speech coding is more robust than other forms of preprocessing defenses in mitigating adversarial examples. This research also proposes

tual quality of the synthesized speech. Narrowband (NB) coding refers to coding of speech signals whose bandwidth is less than 4 kHz (8 kHz sampling rate), while wideband (WB) coding refers to coding of 7-kHz-bandwidth signals (14–16 kHz sampling rate). NB coding is more common than WB coding mainly because of the narrowband nature

Speech Coding • It is a procedure to represent a digitized speech signal using as few bits as possible while maintaining the speech quality. • It is the process to convert speech signal with higher bit rate to lower bit rate. • It is a speech compression process.

Waveform Coding - an overview | ScienceDirect Topics

Time domain waveform codecs encode the speech signal as a full-band signal and map it into as close a replica of the input as possible. The difference between various coding schemes is their way of using prediction to reduce the variance of the signal to be encoded in order to reduce the number of bits necessary to represent the encoded waveform.
