We present in this paper a novel subspace approach for single channel speech enhancement and speech recognition in highly noisy environments. Our algorithm is based on principal component analysis and the optimal subspace selection is provided by a minimum description length criterion. This choice overcomes the limitations encountered with other selection criteria, like the overestimation of th...

This paper illustrates the advantages of using the Discrete Cosine Transform (DCT) as compared to the standard Discrete Fourier Transform (DFT) for the purpose of removing noise embedded in a speech signal. The derivation of the Minimum Mean Square Error (MMSE) ®lter based on the statistical modelling of the DCT coecients is shown. Also shown is the derivation of an over-attenuation factor bas...

This paper presents a speech enhancement method based on the tracking and denoising of the formants of a linear prediction (LP) model of the spectral envelope of speech and the parameters of a harmonic noise model (HNM) of its excitation. The main advantages of tracking and denoising the prominent energy contours of speech are the efficient use of the spectral and temporal structures of success...

the confrontation between iranian and western musical cultures and especially taking the idea of western orchestra is a topic that had incongruous dimensions in iranian music. therefore, this process leads up to some questions: what is the relationship between the multiplicity of musical performance and identity of iranian music? and the other question: did such a process in its different dimen...

Evaluation has been suggested to be one of the main trends in current NIME research. However, the meaning of the term for the community may not be as clear as it seems. In order to explore this issue, we have analyzed all papers and posters published in the proceedings of the NIME conference from 2012 to 2014. For each publication that explicitly mentioned the term “evaluation”, we looked for: ...

When generating musical sound on a digital computer, it is important to have a good model whose parameters provide a rich source of meaningful sound transformations. Three basic model types are used widely today for musical sound generation: instrument models, spectrum models, and abstract models. Instrument models attempt to parameterize a sound at its source, such as a violin, clarinet, or vo...

Music training may strengthen auditory skills that help children not only in musical performance but in everyday communication. Comparisons of musicians and non-musicians across the lifespan have provided some evidence for a "musician advantage" in understanding speech in noise, although reports have been mixed. Controlled longitudinal studies are essential to disentangle effects of training fr...

Body movements in man are frequently observed in relation to musical rhythms. In this study we have investigated the effect of strongly rhythmic music on corticospinal drive to the ankle extensor and flexor muscles involved in foot tapping. Surface electromyographic (EMG) recordings were made from tibialis anterior (TA) and lateral gastrocnemius (LGN) muscles in 12 normal subjects. Rock music w...
