Acoustic Analysis of EkeGusii Vowel System

This study describes the vowel system of EkeGusii(“Bantu E.42”)(Guthrie,1948)in an acoustic phonetics perspective using oral data got from purposively sampled subjects:four adult males,four adult females and four children(two boys and two girls all 8 years old)equally from the two dialects of EkeGusii(EkeMaate and EkeRogoro Dialects).In order to capture the distribution characteristics of the vowel acoustic concentration,the group frequency means are normalized using Lobanov’s(1971)algorithm.Two viewpoints are the subjects of analysis in EkeGusii vowels:(a)acoustic vowel space as projected by the intersection of F2 vs.F1 or quadrilateral,and(b)spatial features of high,low,front and back.These qualities are mainly influenced by the physiology of speakers and social variability as occasioned by gender,age and dialect.The results indicate that children have no gender difference in formants,and have the highest frequencies for all formants,followed by adult females and then adult males.Furthermore,acoustic vowel space and spatial features are affected by gender,age,and dialect.A vowel pattern,replicated by all informants,is realized in the dispersion of the vowels within the chart influenced by gender and age.This study found out that EkeGusii seems to adopt a seven-vowel system of/i eɛaɔo u/with a length contrast.

A Useful System in Learning and Teaching English Pronunciation——IPA Cardinal Vowels System

The paper introduces the cardinal vowels system invented by the famous English phonetician Daniel Jones.This system enables a teacher to describe to his students a foreign vowel by comparing it with the nearest vowel in his mother tongue,which makes the learning of a foreign sound much easier to his students.Two cases of teaching Chinese students English vowels are taken as an example to illustrate the point.IPA cardinal vowel system is of use in terms of teaching and learning English.Two suggestions are put forward in the end.

Letters of the Hebrew Alphabet:As Sound Notation

While Bronze Age Proto-Sinaic and Proto-Canaanite syllabic inscriptions were found engraved on fragments of pottery and stone,evidence of early alphabetic script was also inscribed in ink onto a massive parchment scroll,known as the Torah.Albeit the contours of those original characters transformed over time,it took the clairvoyant genius of Moses,and later the scribes of Ancient Israel,to configure and adapt ancient semitic prototypes into phonetic letters,producing the greatest literary document in the history of the world,the Bible.This article summarizes the acoustic properties of that alphabet,with further historical considerations.

On the Vowel Changes of English Language in History

The Vowel changes of English are more dramatic and complicated in every period of English development. Especially theGreat Vowel Shift from Middle English to Modern English influenced the whole English phonetic system. This paper examines thevowel changes in each period of English development and aims at concluding the rules of the language change and development.

Payload Capacity Scheme for Quran Text Watermarking Based on Vowels with Kashida

The most sensitive Arabic text available online is the digital Holy Quran.This sacred Islamic religious book is recited by all Muslims worldwide including non-Arabs as part of their worship needs.Thus,it should be protected from any kind of tampering to keep its invaluable meaning intact.Different characteristics of Arabic letters like the vowels(),Kashida(extended letters),and other symbols in the Holy Quran must be secured from alterations.The cover text of the Quran and its watermarked text are different due to the low values of the Peak Signal to Noise Ratio(PSNR)and Embedding Ratio(ER).A watermarking technique with enhanced attributes must,therefore,be designed for the Quran’s text using Arabic vowels with kashida.The gap addressed by this paper is to improve the security of Arabic text in the Holy Quran by using vowels with kashida.The purpose of this paper is to enhance the Quran text watermarking scheme based on a reversing technique.The methodology consists of four phases:The first phase is a pre-processing followed by the second phase-the embedding process phase—which will hide the data after the vowels.That is,if the secret bit is“1”,then the kashida is inserted;however,the kashida is not inserted if the bit is“0”.The third phase is the extraction process and the last phase is to evaluate the performance of the proposed scheme by using PSNR(for the imperceptibility)and ER(for the capacity).The experimental results show that the proposed method of imperceptibility insertion is also optimized with the help of a reversing algorithm.The proposed strategy obtains a 90.5%capacity.Furthermore,the proposed algorithm attained 66.1%which is referred to as imperceptibility.

AN ANALYSIS OF ACOUSTIC CHARACTERISTICS OFCLEFT PALATE SPEECH WITH COMPUTERIZED SPEECH SIGNAL PROCESSING SYSTEM

The acoustic characteristics or the chinese vowels of 24 children with cleft palate and 10 normal control children were analyzed by computerized speech signal processing system (CSSPS),and the speech articulation was judged with Glossary of clert palate speech(GCPS).The listening judgement showed that the speech articulation was significantly different between the two groups(P<0.01).The objective quantitative measurement suggested that the formant pattern(FP)of vowels in children with cleft palate was different from that of normal control children except vowel[a](P< 0.05).The acoustic vowelgraph or the Chinese vowels which demonstrated directly the relationship of vocal space and speech perception was stated with the first formant frequence(F1)and the second formant frequence(F2).The authors conclude that the values or F1 and F2 point out the upward and backward tongue movement to close the clert, which reflects the vocal characteristics of trausmission of clert palate speech.

Using Formants to Compare Short and Long Vowels in Modern Standard Arabic

This study was concerned with the short vowels in modern standard Arabic words with Consonant Vowel-Consonant Vowel-Consonant Vowel (CVCVCV) structure, and the long vowels in words with Consonant Vowel Vowel-Consonant (CVVC). 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.

Perception of English Tense and Lax Vowel Contrasts in Chinese Learners of English

Recognition of vertical vowel graphemes of Korean characters based on combination of vowel graphemes

Korean characters consist of 2 dimensional distributed consonantal and vowel graphemes. The purpose of reducing the 2 dimensional characteristics of Korean characters to linear arrangements at early stage of character recognition is to decrease the complexity of following recognition task. By defining the identification codes for the vowel graphemes of Korean characters, the rules for combination of vowel graphemes are established, and a recognition algorithm based on the rules for combination of vowel graphemes, is therefore proposed for vertical vowel graphemes. The algorithm has been proved feasilbe through demonstrating simulations.

Using Formants to Extract Short Vowels from Arabic Words with (Consonant Vowel)³Structure

Arabic texts suffer from missing short vowels. 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.

从八思巴字对音看《蒙古字韵》的“寒”韵——兼论《中原音韵》的桓欢韵及其在近代汉语中的语音性质

《中原音韵》的桓欢韵,在《蒙古字韵》中是"八寒"韵的一部分,其韵母标为on,主元音是o,与寒山韵的主元音a形成明显的对立。但从音理上讲,大中原地区不可能出现独立桓欢韵的圆唇主元音,所以《蒙古字韵》中on的实际音值当为un。但从八思巴字的体系来看,o不可能作介音,我们认为这是由于不同语言(或文字体系所反映)的元音系统构型不同,对译时因没有相当的音位,而取相对音近的成分替代造成的后果。
