Speech quality evaluation is an extremely important problem in modern communication networks. Service providers always strive to achieve a certain Quality of Service (QoS) in order to ensure customer satisfaction. Modeling the speech quality becomes an urgent issue. In this project a computable model for different time scale speech quality evaluation, called E-Model is developed. The results in...
This paper describes two experiments aimed at exploring the relationship between objective properties of speech and perceived pronunciation quality in read and spontaneous speech, with a view to determining whether such quantitative measures can be used to develop objective pronunciation tests. Read and spontaneous speech of two groups of 60 learners of Dutch as a second language was scored for...
Recently, in the language testing field, automatic speech recognition (ASR) technology has been used to automatically score speaking tests. This paper investigates the impact of audio quality on ASR-based automatic speaking assessment. Using the read speech data in the International English Speaking Test (IEST) practice test, we annotated audio quality and compared scores rated by humans, speec...
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 senior student 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 inte...
This paper analyzes the performance of various single channel speech enhancement systems when they are applied to automatic speech recognition (ASR) systems as a preprocessor. Until now the researches on speech enhancement algorithms have focused on improving the perceptual quality of speech signal. However, it has not been verified yet whether the improvements of the perceptual quality also in...
