The Ensemble Interval Histogram (EIH) is an auditory model which can be used as a robust \front-end" for speech recognition systems. The utilization of multiple level-crossing detectors in the EIH provides frequency and intensity information, which may be useful for speech processing. Proper determination of the number of levels and the level values is very important for reliable performance of...
Abstract Background: There is always an interaction between man and his environment that can be the cause of physical, physiological and psychological stress on people and also cause discomfort, annoyance, and have direct and indirect effects on their performance and productivity, health and safety. People in their workplace are exposed to many factors related to work activities and environmen...
There are various traditions emphasizing the distinction between the person who speaks and his speech. This shows the importance of understanding and evaluating a speech by itself without considering the speaker. But there are other traditions that emphasize thorough knowledge of speakers so as not to accept everyone's speech. There is an attempt here to study and survey these two groups of tra...
Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...
The widely shocking attacks on the World Trade Center and the Pentagon on September 11 was interpreted differently by various institutions worldwide, ranging from America's legitimate motive to begin a 'war on terror' to defend her 'very freedom', to a pretext for Bush administration to pursue G. H. W. Bush's temptation for 'a new world order'. Various institutions, therefore, made use of their...
background: speech perception ability depends on auditory and extra-auditory elements. the signal-to-noise ratio (snr) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. speech in noise perception difficulty is a common complaint of the elderly. in this study, the importance of snr magnitude as an extra-auditory effect on speech...

in this paper, genetic programming is applied for quality improvement of noisy speech signal. therefore, a system including both spectral subtraction and genetic programming is implemented for speech enhancement. in the proposed method, first noise is reduced by spectral subtraction. in the next step, genetic programming trees are trained for more enhancement of noisy signal by mapping the sign...
Objective: The purpose of the present research was to compare speech intelligibility in children with cochlear implant, with hearing aids and normal hearing in Tehran province. Materials & Methods: Sixty children underwent this analytic and comparative research. They were divided into three groups and each group contains 20 children.
