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...

Storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. We used stochastic inter-frame interpolators and vector quantization (VQ) as a new method for developing a high quality 1200 BPS speech vocoder. The objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 BPS standard vocoders (as CELP).

Speech sciences deal with the acoustical characteristics of speech by means of sophisticated soft wares as well as hard wares. Although, a speech science is a well known science in the developed countries, especially the western societies, however, it has been remained almost unknown in Iran, though, in recent years a group of scholars have been involved in this branch of science. The applicati...

Abstract   Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...

the main goal of early detection of hearing impairment in children is early intervention. there is growing interest in early detection of hearing impairment in developing countries. the main purpose of this study was to investigate the spoken language development in severe to profound hearing impaired children and compared their speech intelligibility with normal hearing children at the same ag...

the current study was carried out to investigate the functions of the ritual speech act of ‘ya allah’ (literally meaning ‘o god’) employed by iranians in social interactions. to this end, sixty-two persian native speakers of different age groups, ranging from 35 to 85, of both genders were observed in 250 natural situations such as daily interactions, gatherings, public or private places and lo...

background and aim: it will be discussed about five mechanisms in relation to speech in noise perception; including neural encoding and decoding, centrifugal pathways, pitch perception, asymmetric sampling in time and cognitive skills. these mechanisms are related to each other and each is important to recognize speech in noise. in this article, we have tried to rely on the latest studies to de...

the use of the internet as a source of information gathering, self-help and support is becoming increasingly recognized. parents and professionals of children with hearing impairment have been shown to seek information about different communication approaches online. cued speech is a very new approach to persian speaking pupils. our aim was to develop a useful website to give related informatio...
