We use the terms speech coding and voice coding interchangeably in this paper. Speech coding is a widely accepted terminology, and there seems to be no reason to distinguish between voice and speech, unless a restricted definition of one or the other is adopted. Generally, it is desired to reproduce the voice signal, since we are interested in not only knowing what was said, but also …

SPEECH CODING Speech coding is a talent of compressing and then converting speech signals for effective transmission or stowage. Speech coding system initially having the input speech signal which is in the form of analog in nature is need to digitized using a sampler, analog to digital converter and a filter. Speech coding techniques are mainly two types which are

Human voice). For each time slice (eg 20ms): Analyse the audio signal to determine how the signal was produced. Determine the model parameters that fit. Send the model parameters. At the receiver, synthesize the voice from the model and received parameters. Larynx (vocal cords) Vocal tract (resonance) Lips and tongue Speech formation

• Voice Coders (Vocoders): • Speech signal is assumed to be generated from a model which is controlled by some parameters. • During encoding, parameters of the model are estimated from the input speech signal. • Then the parameters are transmitted as the encoded bit-stream. • Quality of the decoded speech depends on model. • Low bit rate coder.

• Speech coding refers to a process that reduces the bit rate of a speech file • Speech coding enables a telephone company to carry more voice calls in a single fiber or cable • Speech coding is necessary for cellular phones, which has limited data rate for each user (<=16 kbps is desired!).

speech coding include cellular communication, voice over internet protocol (VOIP), videoconferencing, electronic toys, archiving, and digital simultaneous voice and data (DSVD), as well as numerous PC-based games and multimedia applications. Speech coding is the art of creating a minimally redundant representation of the speech signal that can
Speech coding - Wikipedia
https://wiki-mirror.cla.umn.edu/wiki/Speech_coding
Speech coding is an 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 modeled parameters in a compact bitstream. Some applications of …

Example of coding techniques ZIP: no transformation nor quantization, apply VLC (LZW) to the stream of letters (symbols) in a file directly, lossless coding PCM for speech: no transformation, quantize the speech samples directly, apply fixed length binary coding ADPCM for speech: apply prediction to original samples, the predictor is adapted from one speech frame …
