Hammerstein Model for Speech Coding [PDF]
A nonlinear Hammerstein model is proposed for coding speech signals. Using Tsay's nonlinearity test, we first show that the great majority of speech frames contain nonlinearities (over 80% in our test data) when using 20-millisecond speech frames. Frame

Speech rhythms and multiplexed oscillatory sensory coding in the human brain.
Cortical oscillations are likely candidates for segmentation and coding of continuous speech. Here, we monitored continuous speech processing with magnetoencephalography (MEG) to unravel the principles of speech segmentation and coding.

We propose an approach for cognitive coding of speech by unsupervised extraction of contextual representations in two hierarchical levels of abstraction. Speech attributes such as phoneme identity that last one hundred milliseconds or less are captured in the lower level of abstraction, while speech attributes such as speaker identity and emotion that ...

Speech spectral quantizers for wideband speech coding [PDF]
AbstractIn this treatise a rangeof Line Spectrum Frequency(LSF) Vector Quantization (VQ) schemes were studied comparatively, which were designed forwideband speech codecs.Both predictive arrangements and memoryless schemes were investigated. Specifically, both memoryless Split Vector Quantization (SVQ) and Classified Vector Quantization (CVQ) were ...
