Speech signals degraded by additive noise can affects different applications in telecommunication. The noise may degrades the intelligibility of the speech signals and its waveforms as well. In some applications such as ...

Mel-frequency cepstral coefficients introduced biologically-inspired features into speech technology, becoming the most commonly used representation for speech, speaker and emotion recognition, and even for applications ...

This paper describes a speech enhancement system (SES) based on a TMS320C31 digital signal processor (DSP) for real-time application. The SES algorithm is based on a modified spectral subtraction method and a new speech ...

The phonoarticulatory diadochokinesis test has been recommended to evaluate neurological disorders. It is a speech task that consists of the ability to repeat at high speed a segment of speech. The purpose of this research ...

Background: distance learning (DL) is becoming a higher education modality with a meaningful impact. It offers students flexibility, mobility and choices. Also it can reach a greater number of professionals and students ...

BACKGROUND: One of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis--although frequently used--, as it is influenced by socioeconomic and cultural aspects as ...
