Throat microphones (TM) which are robust to background noise can be used in environments with high levels of background noise. Speech collected using TM is perceptually less natural. The objective of this paper is to map the spectral features (represented in the form of cepstral features) of TM and close speaking microphone (CSM) speech to improve the former’s perceptual quality, and to represe...
Background and purpose: We can examine the language abilities of a person through five parameters of speech quality including speech fluency, speech complexity, speech exactness, speech rate and lexical accessibility. These parameters are examined by the secondary parameters including mean length of utterance (MLÜ), mean length of five long utterances, mean number of verb in sentence, mean nu...
Monitoring speech quality in telephone networks is a two-step procedure. First, all data which are relevant for speech quality have to be measured during network operation. Then, models can be defined which calculate quality indices on the basis of the measurements. This talk will give an overview of monitoring approaches related to speech communication quality, which is one component of the qu...
Most traditional objective indices don’t distinguish between a real sound and a perceived sound, and therefore, these indices have limitations in regard to the evaluation of the real effect of an algorithm under investigation on the auditory perception of a hearingimpaired person. Though several objective indices, such as perceptual evaluation of speech quality (PESQ) and composite measurements...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
This article presents a framework for overviewing the performance of fundamental frequency (F0) estimators and evaluates its effectiveness. Over the past few decades, many F0 estimators and evaluation indices have been proposed and have been evaluated using various speech databases. In speech analysis/synthesis research, modern estimators are used as the algorithm to fulfill the demand for high...

this paper is a short review on the jann and content of speech and language rehabilitation services and the trend of their institutionalization in iran. a summary of formal education in speech and language therapy in iran as originated by establishing a 4 year bs rehabilitation program in the college of rehabilitation sciences in tehran in 1974 is given. since then, speech and language rehabili...
The author shows that the use of high-resolution spectrum estimation methods instead of Fourier-based techniques can improve the accuracy of measurement of spectral parameters of distorted waveforms encountered in power systems, in particular the estimation of the power quality indices (such as inter/harmonic groups and subgroups). The comparison of the frequency and amplitude estimation error,...
