This egocentric selection by the cortex, which emphasizes behaviorally-relevant and frequently occurring signals, results in increased response amplitudes, sharper neural tuning and decreased response latency for subcortical neurons that are matched to the parameters of the characterizing sound [52], [57], [58].
To better characterize sounds that are quite different from speech, a high-resolution spectrogram patch (a window of spectrogram frames stacked together) is directly used as input shown in Fig. 1 a.
This study describes the development of a model to characterize sound environments, in urban agglomerations, which takes into account both temporal and spatial structure.
The flow of heat is governed by equations that are similar to the wave equation used to characterize sound propagation in air.
Based on a run-time geometric analysis of the deforming surface, we identify resonating regions characterizing the sound being produced.
The success of this design is strongly linked with the accuracy of the acoustic models in characterizing the sound pressure level distribution inside the train coach.
Similarly, i-vectors find new axes for describing the information that characterizes speech sounds in the 120,000-dimension space.
The Center for Cellular Construction is organized around five interacting projects that are designed to facilitate the iterative process that characterizes sound research in both basic science and applied R&D settings.
Finally, we demonstrate how the emergent ensembles contour the high-energy spectro-temporal modulations of natural sounds, forming a discriminative representation that captures the full range of modulation statistics that characterize natural sound ensembles.
However, HMM has the shortcoming of assuming the observations being independent within each state, which makes it ineffective in modeling the fine details of speech temporal evolutions that are important in characterizing nonstationary speech sounds [1].
Compared with wild-type littermates, S321X heterozygotes showed significant differences in 5 of the 16 measures characterizing the animals' sounds: they emitted fewer USDs (Fig. 4b), fewer ultrasounds (USIs and USDs) with frequency jumps (Fig. 9), high-noise DCs with lower SPLs (Fig. 11b) and USIs with longer inter-call intervals (Fig. 8c).
