This paper examines four acoustic properties (duration F0, F1, and F2) of the monophthongal vowels of Iberian Spanish (IS) from Madrid and Peruvian Spanish (PS) from Lima in various consonantal contexts (/s/, /f/, /t/, /p/, and /k/) and in various phrasal contexts (in isolated words and sentence-internally). Acoustic measurements on 39 speakers, balanced by(More)
This study reports on the acoustic properties of the front vowel /i/ and the fronted back vowel /u/ in Standard Southern British English (SSBE). These two vowels are realized with very similar (and for some tokens overlapping) values of F2, so that F2 does not seem to be a reliable acoustic cue for the distinction between the two vowels. To test further(More)
We investigate whether there is a within-speaker effect of a higher F0 on the values of the first and the second formant. When asked to speak at a high F0, speakers turn out to raise their formants as well. In the F1 dimension this effect is greater for women than for men. We conclude that the general formant raising effect might be due to the physiology of(More)
L2 studies demonstrate that learners differ in their speech perception patterns. Recent explanations attribute this variation to the different initial stages with which learners start their L2 development. Spanish listeners' categorization of Standard Southern British English and American English vowels is compared. The results show that, on the basis of(More)
It has been observed that in production, the boundary between the vowels /i/ and /e/ is diagonal, i.e. it involves both F1 and F2; in perception, by contrast, the boundary has been observed to be horizontal, i.e. listeners do not use F2 as a cue for distinguishing the two vowels. The same is true of the /u–o/ boundary. With computer simulations of virtual(More)
Naive listeners' perceptual assimilations of non-native vowels to first-language (L1) categories can predict difficulties in the acquisition of second-language vowel systems. This study demonstrates that listeners having two slightly different dialects as their L1s can differ in the perception of foreign vowels. Specifically, the study shows that Bohemian(More)
In some languages (e.g. Czech), changes in vowel duration affect word meaning, while in others (e.g. Spanish) they do not. Yet for other languages (e.g. Dutch), the linguistic role of vowel duration remains unclear. To reveal whether Dutch represents vowel length in its phonology, we compared auditory pre-attentive duration processing in native and(More)
We present a method for assessing categorical perception from continuous discrimination data. Until recently, categorical perception of speech has exclusively been measured by discrimination and identification experiments with a small number of repeatedly presented stimuli. Experiments by Rogers and Davis [1] have shown that using non-repeating stimuli(More)
The present study investigated whether listeners perceptually map phonetic information to phonological feature categories or to phonemes. The test case is a phonological feature that occurs in most of the world's languages, namely vowel height, and its acoustic correlate, the first formant (F1). We first simulated vowel discrimination in virtual listeners(More)
This study explored effects of simultaneous use of late bilinguals' languages on their second-language (L2) pronunciation. We tested (1) if bilinguals effectively inhibit the first language (L1) when simultaneously processing L1 and L2, (2) if bilinguals, like natives, imitate subphonemic variation, (3) if bilinguals' imitation operates(More)
