“…It is well known that Spanish vowels are longer before voiced consonants (Chen, 1970;Mendoza et al, 2003;Zimmerman and Sapon, 1958), and that they have an intrinsically different duration induced by height (i.e. low vowels are longer than high vowels; Chládková and Escudero, 2012;Mendoza et al, 2003).…”

“…Additionally, it is known that Spanish vowels are longer before voiced consonants (Chen, 1970;Mendoza et al, 2003;Zimmerman and Sapon, 1958) and that they have intrinsically different durations (i.e. duration is positively correlated with F 1 , thus low vowels are longer than high vowels; Chládková and Escudero, 2012;Mendoza et al, 2003). Morrison (2008) affirmed that L1-Spanish speakers are attuned to duration to some degree due to allophonic variation, and that this experience is transferred to the L2 in one of the initial stages of learning (for a complete account of the proposed developmental stages in L2 learning, see Escudero, 2000).…”

The present study explored the production and perception of the /i/-/I/ vowel contrast in second language (L2)-dominant early learners of American English who no longer fluently speak their first language (L1, Spanish). The production task analyzed the extent to which the early learner group differed from controls (native English speakers and L1-Spanish late-onset learners of English) with regard to duration and spectral centroids. The perception experiment examined how these early learners classified resynthesized stimuli drawn from the /i/-/I/ contrast using distinct acoustic cues - spectral and temporal - in a 2-alternative forced choice identification task. The first experiment revealed that the early learners produced the contrast in a native-like manner in terms of the spectral envelope and duration use. The second experiment found that early learners differed from both control groups in how they categorized the /i/-/I/ continua based on spectrum and duration, and the extent to which they rely on these two cues. The effects of linguistic experience on L2 phonetic behavior are discussed.

“…Cross-linguistically, low vowels tend to be produced with longer duration than high vowels of identical phonological length (House and Fairbanks, 1953, p. 111;Lehiste, 1970, p. 18), so one expects this correlation to hold for Spanish, where vowels have no phonological length contrast. For Spanish women and men from Granada, Mendoza et al (2003) indeed found that the low vowel /a/ was produced longer than the high vowels /i / and/u/. Similarly, Marín Gálvez (1994-1995) found that /a/ was longer than /e/ and /o/, and these longer than /i/ and /u/, for two male speakers of an unspecified variety of Iberian standard Spanish.…”

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 dialect and gender, can be generalized to the following differences between the two dialects. The vowel /a/ has a lower first formant in PS than in IS by 6.3%. The vowels /e/ and /o/ have more peripheral second-formant (F2) values in PS than in IS by about 4%. The consonant /s/ causes more centralization of the F2 of neighboring vowels in IS than in PS. No dialectal differences are found for the effect of phrasal context. Next to the between-dialect differences in the vowels, the present study finds that /s/ has a higher spectral center of gravity in PS than in IS by about 10%, that PS speakers speak slower than IS speakers by about 9%, and that Spanish-speaking women speak slower than Spanish-speaking men by about 5% (irrespective of dialect).

“…The 113 F1-F2 pairs were synthesized with three different durations equidistant on the logarithmic scale, namely, 100, 141, 200 ms. The values of 100 and 141 ms roughly correspond to those of (stressed) vowels in Spanishand Portuguese-speaking men (Mendoza, 2003;Costa, 2004); a third duration of 200 ms was used to add more variability to the stimulus set. Thus, there were 339 stimuli, 113 different F1-F2 pairs with three different duration values.…”

Recent acoustic descriptions have shown that Spanish and Portuguese vowels are produced differently in Europe and Latin America. The present study investigates whether comparable between-variety differences exist in vowel perception. Spanish, Peruvian, Portuguese, and Brazilian listeners were tested in a vowel identification task with stimuli sampled from the whole vowel space. The mean perceived first (F1) and second formant (F2) of every vowel category were compared across varieties. For both languages, perception exhibited the same between-variety differences as production for F1 but not F2, which suggests correspondence between produced F1 and perceived vowel height but not between F2 and frontness. (2011) compared Spanish vowels produced by speakers from Peru and Spain. Betweendialect differences were observed in all three languages. Specifically, Brazilian Portuguese (BP) vowels are slightly longer than European Portuguese (EP) vowels, and BP /e/, /a/, and /O/ have higher F1 values than their EP counterparts, while no dialectal differences were reported for vowel F2. Peruvian Spanish (PS) speakers speak more slowly than European Spanish (ES) speakers but vowels are not significantly longer in PS than in ES, /a/ has higher F1 values in ES than in PS, and /e/ and /o/ are more peripheral in PS than in ES with respect to F2. The present study investigates whether these vowel production differences have similar counterparts in vowel perception, i.e., whether there is a clear interrelation between the production and the perception of vowels.
