The speech enhancement techniques are often employed to improve the quality and intelligibility of the noisy speech signals. This paper discusses a novel technique for speech enhancement which is based on Singular Value Decomposition. This implementation utilizes a Genetic Algorithm based optimization method for reducing the effects of environmental noises from the singular vectors as well as t...

in recent years, sub-band speech recognition has been found useful in addressing the need for robustness in speech recognition, especially for the speech contaminated by band-limited noise. in sub-band speech recognition, the full band speech is divided into several frequency sub-bands, with the result of the recognition task given by the combination of the sub-band feature vectors or their lik...

BACKGROUND Wide cleft palate is a common congenital anomaly, particularly in developing countries with limited access to plastic surgeons and specialized centers. It can be severe may contribute the development of oronasal fistula, which occur up 78% cases. Despite numerous surgical techniques for wide repair, best method remains unclear. This study aimed identify repair minimize occurrence fis...

BACKGROUND Noninvasive positive-pressure ventilation (NPPV) is commonly used to improve ventilation and oxygenation in patients with acute respiratory failure (ARF). Mask leak and intolerance due to facial discomfort or claustrophobia often occur with NPPV and are frequently cited reasons for treatment failure. METHODS Retrospective review of patient records from a tertiary-care referral hosp...

this study was an attempt to find out to what extent efl learners at different levels of language proficiency experience inner speech as mental rehearsal and to identify some of the characteristics and functions of their inner speech. for this purpose, one hundred seventy-four iranian female students majoring in english translation at islamic azad university, tehran central branch, took part in...

setup of an emotion recognition or emotional speech recognition system is directly related to how emotion changes the speech features. in this research, the influence of emotion on the anger and happiness was evaluated and the results were compared with the neutral speech. so the pitch frequency and the first three formant frequencies were used. the experimental results showed that there are lo...

Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
