Listening taking over half of the learners’ time and effort (Nunan, 1998), forms a basis for acquiring much of a language. There are factors affecting listening comprehension and its perception, such as the speech rate, phonological properties of the text, the quality of the recording, the learners’ anxiety, and listening comprehension strategies (Goh, 2000; Hamouda, 2013). At the Iran Language...

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).

Background: Rapid advances in technology, especially in the field of telecommunication, have led to extraordinary levels of mothers’ exposures to radiofrequency electromagnetic fields (RF-EMFs) prior to or during pregnancy.Objective: The main goal of this study was to answer this question whether exposure of women to common sources of RF-EMFs either prior to or during pregnancy is related to ...

One of the important issues in speech emotion recognizing is selecting of appropriate feature sets in order to improve the detection rate and classification accuracy. In last studies researchers tried to select the appropriate features for classification by using the selecting and reducing the space of features methods, such as the Fisher and PCA. In this research, a hybrid evolutionary algorit...

800x600 background: nowadays, mothers are continuously exposed to different sources of electromagnetic fields before and even during pregnancy.   it has recently been shown that exposure to mobile phone radiation during pregnancy may lead to adverse effects on the brain development in offspring and cause hyperactivity. researchers have shown that behavioral problems in laboratory animals which ...

Abstract The reproducibility of scientific studies grounded on language corpora requires approaching each step carefully, from data selection and pre-processing to significance testing. In this paper, we report our reproduction a recent study based well-known conversational corpus (Switchboard). reproduced Cohen Priva et al. (J Acoust Soc Am 141(5):2989–2996, 2017) focuses speech rate convergen...
