Review of methods for coding of speech signals
EURASIP Journal on Audio, Speech, and Music Processing, 2023 Speech is the most common form of human communication, and many conversations use digital communication links. For efficient transmission, acoustic speech waveforms are usually converted to digital form, with reduced bit rates, while maintaining decoded ...

SPEECH COMPRESSION TECHNIQUES: A REVIEW
, 2021 Speech is the vocalizer form of human communication,and based upon the syntactic combination of lexical and vocabularies. The aim of speech coding is to compress the speech signal to the highest possible compression ratio but maintaining user ...

Music as a scaffold for listening to speech: Better neural phase-locking to song than speech
NeuroImage, 2020 Neural activity synchronizes with the rhythmic input of many environmental signals, but the capacity of neural activity to entrain to the slow rhythms of speech is particularly important for successful communication.

Comparative Study of Wideband Speech Spectral Quantization Schemes
, 2000 In this treatise a range of Line Spectrum Frequency (LSF) Vector Quantization (VQ) schemes were studied comparatively, which were designed for wideband speech codecs. Both predictive arrangements and memoryless schemes were investigated.
