Sentence examples for modulation spectrum and from inspiring English sources

Table 2 shows the results obtained with SC systems operating on modulation spectrum and Mel-spectrum features and the MLP-based systems trained with multi-condition data.

Distortions due to reverberation have a direct impact on the modulation spectrum, and they also cause substantial difficulties for human listeners [15],[15].

The paper is organized as follows: Section Related work gives an overview of the auditory-inspired features including gammatone filter bank processing, modulation spectrum and non-linearity processing.

It incorporates a combination of gammatone filtering, modulation spectrum and non-linearity for feature extraction in the recognition chain to improve robustness, more specifically the ASR in adverse acoustic conditions.

(b) Traces obtained from fusing the probability estimates obtained with the full modulation spectrum and the probability estimates obtained from nine modulation bands (weights obtained with a genetic algorithm).

Table2 shows the results for gammafrequency with modulation spectrum (GFCC-MS), gammafrequency with modulation spectrum and non-linearity (GFCC-MS-NL) and gammafrequency with non-linearity (GFCC-NL) feature extraction techniques.

In total, a 205-dimensional feature vector is obtained: 19 LLD (and 19 delta coefficients), each summarised by 5 functionals ((19+19)·5=120), 12 LTAS features, 2 modulation spectrum features, and the equivalent sound level, yield a total of 205 features.

We deliberately use unadorned implementations of both the modulation spectrum analyser and the sparse coder, because we see a need for identifying what are the most important issues that are involved with a fundamentally different approach to representing speech signals and with converting the representations to state posterior estimates.

The overall power spectrum and modulation spectrum are preserved.

The present paper describes an alternate approach, in which the gammatone filtering, non-linearity and modulation spectrum for feature extraction are combined.
