Some acoustic and articulatory correlates of phrasal stress in Spanish

چکیده
All spoken languages show rhythmic patterns. Recent work with a number of different languages (English, Japanese, Mandarin Chinese, and French) suggests that metrically (hierarchically) assigned stress levels of the utterance show strong correlations with the amount of jaw displacement, and corresponding F1 values. This paper examines some articulatory and acoustic correlates of Spanish rhythm; specifically, we ask if there is a correlation between phrasal stress values metrically assigned to each syllable and acoustic/articulatory values. We used video recordings of three Salvadoran Spanish speakers to measure maximum jaw displacement, mean F0, mean intensity, mean duration, and mid-vowel F1 for each vowel in two Spanish sentences. The results show strong correlations between stress and duration, and between stress and F1, but weak correlations between stress and both mean vowel intensity and maximum jaw displacement. We also found weak correlations between jaw displacement and both mean vowel intensity and F1.

Jaw displacement and phrasal stress in Mandarin Chinese
Spoken languages have rhythmic structures, often phonologically described in terms of the metrical phrasal stress patterns of that language [1, 2, 3, 4]. Recent studies with English, Japanese, and Spanish suggest that rhythmic phrasal stress patterns are articulated by syllable to syllable jaw displacement variations, with concomitant syllable to syllable changes in vocal tract resonance freque...

Foreign language learners tend to avoid phonological difficulties and simply transfer sounds whether from their L1 or any pre-existing L2. Phonological awareness (PA) gives students an active role in understanding their own potential in improving pronunciation through several methods. However, such methods are likely to be restricted to only passive learning methods, such as repetition, reading...

This paper examines some articulatory and acoustic characteristics of American English. The results suggest that the jaw may be the articulatory organizer of phrasal rhythm, manifested acoustically through the F2-F1 pattern. Utterance prominence, such as contrastive emphasis, is additionally manifested by increased F0 along with increased duration on the prominent word. The rhythmical organizat...
متن کاملLexical Stress, Phrasal Accent and Prosodic Boundary in the Realization of Domain-Initial Stops in Dutch
This study examines the effects of prosodic boundaries, lexical stress, and phrasal accent on the acoustic realization of stops (/t, d/) in Dutch, with special attention paid to language-specificity in the phonetics-prosody interface. The results obtained from various acoustic measures show systematic phonetic variations in the production of /t d/ as a function of prosodic position, which may b...
