although the function of neuro-vocal system of the human body was previously suggested in the second half of the 17th century by italian surgeon antonio valsalva”, but its use in speech therapy during the past 30 years. however, its role has not been considered properly for teaching the speech method in the schools of dramatic arts. the present study aims to shed some light on the extreme need ...

one of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. speech synthesis is granting human abilities to the computer for speech production. data-based approach and process-based approach are the two main approaches on speech synthesis. each approach has its varied challenges. unit-selection speech synthesis and statistical parametr...

Objectives: Speech and language development is one of the main aspects of evolution in humans and is one of the most complex brain functions such that it is referred to as one of the highest cortical functions such as thinking, reading and writing. Speech and language disorders are considered as a major public health problem because they cause many secondary complications in the childhood and a...

Background: Previous studies have shown that interaural-time-difference (ITD) training can improve localization ability. Surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (ITD ENV). We sought to investigate the reliability of an ITD ENV-based training program in speech-in-noise perception a...

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...

This study investigated the effectiveness of colligational corpus-based instruction on enhancing the pragmalinguistic knowledge of speech act of request among Iranian intermediate EFL learners. The objective of the study was to find out whether or not providing students with corpora through using colligational instruction had any significant effects on enhancing their pragmalinguistic knowledge...

objectives: one of the most effective methods to describe speech disorders is the measurement of speech intelligibility. the speech intelligibility indicates the extent of acoustic signals that correctly speaker produces and hearer receives. the purpose of this study was to investigate the speech intelligibility in the persian children with down syndrome, age range was 3 to 5 years, who had spo...
