The purpose of the research is to examine how conscious manipulation of facial expressions aids acquisition of foreign vowels by learners, regardless of their native language and the culture they have been brought up in. Taking advantage of achievements derived from such disciplines as psychology of emotions and phonetics depicted as a physical process, an attempt is made to find a tool that improves teaching/learning of foreign vowels, that is to say, an effort is put in search of a useful method to make the phonetic process faster and more accurate. Teachers of English are encouraged to put the method, which is described in detail in the paper, into practice with their own mother languages and to share opinions about the method with colleagues. Similarly, it is believed that it can be applied to courses of other languages than just English. Teachers of those languages are encouraged to try to use it, too.展开更多

Even though there has been a dispute on the precise number of Arabic vowels that exist between language studies, this study used the opinion that the Arabic language has three vowels;the elongation of each vowel gave the other three because this is the opinion of classical Arabic linguists which is the source of the Modern Standard Arabic (MSA). Studies said that the first and second formant values (F1, F2) can represent the vowels. In this study, the formants were measured using LPC (Linear Predictive Coding), verifying the measurement to see if the measured follows the pattern of formants measurements of the other studies, and the formants were used to investigate the relationship between short and long vowels. Furthermore, the study figured out if the dialect of speakers can affect the values of formants, even if the spoken language is MSA, some statistical measurements were calculated to evaluate the relationship.展开更多

Arabic Speech Recognition is not as good as English speech recognition due to the short vowels not being recognized. And the Arabic language is unlike the English language in characteristics such as the number of vowels. English has more than 24 vowels that are close to each other in pronunciation. The Arabic language only has three short vowels that are far from each other in utter and measurement, by elongating those short vowels, long vowels arose. Researchers said that the vowels could be recognized using formants. The formants’ measurements of Arabic vowels are far from each other too, so it is possible to recognize them so that Arabic Speech recognition can give more accurate results. The paper applies this idea to the corpus Phonemes of Arabic. It uses the Euclidian distance method to measure the distances between formant values to recognize Arabic from words with a CV3 structure, the Linear Predictive Coding method and MATLAB to develop the programs that will extract the formants and calculate the means of the short vowels by using the corpus to identify the short vowels within words in the corpus. The results showed that if highly qualified readers were chosen to read the Arabic text, then higher rates of recognition of the short vowels involved in words will be achieved. This paper revealed that some of the characteristics of a language can be utilized for vowel recognition or to enhance the existing methods for speech recognition.展开更多

In such a case, they tend to use their native language sounds in speaking the foreign language. Since some Chinese and English vowel sounds are easy to be confused, applying IPA cardinal vowels in the teaching of English pronunciation will help Chinese learners identify the difference between an English vowel sound and a Chinese vowel sound and thus enables them to make intelligible English speech sounds.展开更多

This paper proposed a parametric statistical modeling for the analysis of these vowels.The parameters were described empirically with the method of probability distribution. The effects of the multiparameter classifications were estimated by the binary and multinomial logistic models, and the method of support vector machine was adopted to carry out the pattern recognition of the classifications. The results show that the parameters of duration, DCT_(1-3)are significant to the external classification, and the parameters of DCT_(0-3) have significant main effects on the internal classification. The automatic testing shows that the hit rate of the external pattern recognition is only 43.6% but the rate is 96.1% of the internal. It indicates that the abrupt feature should be additive rather than distinctive.展开更多

The excitation pattern describes these changes psychoacoustically as inner expression. This study investigates the relations between excitation patterns and their phonetic qualities for Chinese steady-state vowels. First, the peak positions of the envelope of excitation patterns were measured on a database. The results demonstrated that each Chinese vowel has its own special position for the representative peak of the excitation pattern. Second, to examine the sufficiency of these results, a series of experiments that consisted of identification and evaluation tasks were conducted, in which spectral components of natural isolated vowels were manipulated to create certain excitation patterns. Subjects' responses of these stimuli show that the position of the representative peak of the excitation pattern of a vowel plays a crucial role on its phonetic identity. The results suggest that the phonetic identity of vowels is determined by the position of the representative peak of the excitation pattern evoked by it, and other peaks, if any, do not have phonetic meaning. Additionally, several phenomena about speech perception are discussed on the basis of this study.展开更多

Each variable has two realizations: rural [o, o:, e, e:] respectively and urban [a, a:, a, a:] respectively.Fathers use the rural vowels more than mothers, but the difference is statistically insignificant. Like fathers, boys use more rural vowels than girls. However, the difference between boys and girls is statistically significant. No correlation emerged between the children’s and parents’ use of the variants, indicating that children are not acquiring their parents5 exact frequencies, which suggests developmental effect rather than statistical learning of parental input effect. The boys’ higher use of the rural forms after age eight is attributed to a social, psychological polarization process between boys and girls to create a highly differentiated gendered linguistic behavior in line with another highly differentiated gendered linguistic behavior related to a stereotypical consonant variable, (q), which is observed in both parents and children.展开更多

This research will describe how the teacher used some Arabic language methods as a teaching strategy to improve her EFL students' reading, writing, and understanding of English grammar. The research took place over a period of two years in Lebanon and four years in Saudi Arabia. Data consists of comparative tables, videos of two samples of students using Arabic to learn English, and pictures of the teacher using Arabic for comparative in grammar. Results revealed an increase in the level of understanding and comprehension of students in both the elementary and intermediate levels.展开更多
