Investigations have been made on the perceptual and acoustic properties of individual phonemes in continuous speech for different speaking rate. Fifteen short sentences spoken by four male speakers have been used as the test material. Each speaker has been asked to pronounce the sentences with three different rates: normal, first and slow. For perceptual experiment, individual CV-syllables have...

The relative perceptual confusability of the coda nasals /m/, /n/, and /ŋ/ was investigated in Southern Min and Mandarin for insight into the nasal mergers that have happened in the history of the Chinese languages. Coda /m/ was the most confusable of the nasals, mirroring the historical pattern in which the bilabial was the first coda nasal to be lost. In both Southern Min and Mandarin, the al...

Two experiments were conducted to test the hypothesis that higher formant normalization results from the auditory integration of F2 and F3 when they are within 3 Bark of each other. In the first experiment, Formants 3-5 were manipulated in both a "hid"-"head" continuum (in which F2 and F3 are within 3 Bark of each other) and a "hood"-"HUD" continuum (in which F2 and F3 are not within 3 Bark of ...

Vowel identity correlates well with the shape of the transfer function of the vocal tract, in particular the position of the first two or three formant peaks. However, in voiced speech the transfer function is sampled at multiples of the fundamental frequency (F0), and the short-term spectrum contains peaks at those frequencies, rather than at formants. It is not clear how the auditory system e...

Certain of the complex spectral effects of vowel nasalization bear a resemblance to the effects of modifying the tongue or jaw position with which the vowel is produced. Perceptual evidence suggests that listener misperceptions of nasal vowel height arise as a result of this resemblance. Whereas previous studies examined isolated nasal vowels, this research focused on the role of phonetic conte...

A simple method for computer recognition of Telugu speech sounds irrespective of speakers is described. A vocabu­ bulary consisting of 871 Telugu words containing the ten vowels (f'O/./a :/,/i/,/i :/,/u/,/u :/,/e/,/e :/./0/ and /0 :/) in constant­ vowel nucleus-consonant (CNC) combination and uttered by three informants was selected as the testing material. Formant frequencies. Flo F2 and F3 of...

In this article, the low back vowel /A/ in word-final positions in Eghlidian dialect, one of Persian dialects, is studied. This vowel is represented phonetically as [A], [o] and [@] in different phonetic environments. Therefore many words were collected via interviewing ten native speakers so that these different alternant forms can be accounted for appropriately. Since one of the authors of th...

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...
