Automatic vowel quality description using a variable mapping to an eight cardinal vowel reference set
نویسندگان
چکیده
This paper investigates the possibility of describing vowels phonetically using an automated method. Models of the phonetic dimensions of the vowel space are built using two multi-layer perceptrons trained using eight cardinal vowels. The paper aims to improve the positioning of vowels in the open-close dimension by experimenting with a parameter in the model which is the parameter which controls the slope of the sigmoid function employed in the multi-layer perceptrons.

A quantitative theory of cardinal vowels and the teaching of pronunciation
The problem of devising a reference sys tem for specifying the phonetic value of vowels is discussed. The c lass ica l theory of Cardinal Vowels is examined a s well a s previous quantitative frameworks for describing vowel pronunciation.

This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...
متن کاملCritique of the IPA vowel quadrangle, especially the use of vowel points in it
The globally widespread kind of description of vowels by points in the IPA quadrangle with the cardinal vowels as references is very often not trustworthy in its detailed specification. The reasonable interpretation of a dot registration is namely that the vowel quality is very narrowly pinpointed. However, most phoneticians do not have the capacity to judge vowels in this detailed way. Consequ...

This paper examines the influence of the first language on the accuracy with which trained phoneticians judge isolated monophthongs taken from the phoneme systems of two different languages. The main finding of this study was that the speaker’s as well as listener’s L1 background have a significant influence on judgements which were made by means of the IPA vowel diagram. This paper consists of...
