Abstract This paper analyzes the acoustic properties of Spanish stressed mid vowels from a corpus of over 2,800 tokens produced by Galician-dominant bilinguals and Spanish monolinguals. Following principles of bilingual speech production theory, we explore whether these vowels present lexically conditioned open variants [ɛ] and [ɔ] not present in monolingual Spanish. In combination with linguistic factors, we also examine whether bilingual mid-vowel production in our corpus is related to social variables. Assuming a linguistic repertoires perspective that links variation to identity performance, we argue that Spanish /e/ and /o/ are sociolinguistic variables in Galicia and that the distribution of their variants can be exploited to perform social meaning.

The purpose of this study was to describe the acoustic characteristics of Spanish vowels in subjects who had undergone a total laryngectomy and to compare the results with those obtained in a control group of subjects who spoke normally. Our results are discussed in relation to those obtained in previous studies with English-speaking laryngectomized patients. The comparison between English and Spanish, which differ widely in the size of their vowel inventories, will help us to determine specific or universal vowel production characteristics in these patients. Our second objective was to relate the acoustic properties of these vowels to the perceptual data obtained in our previous work (J. L. Miralles & T. Cervera, 1995). In that study, results indicated that vowels produced by alaryngeal speakers were well perceived in word context. Vowels were produced in CVCV word context by two groups of patients who had undergone laryngectomy: tracheoesophageal speakers (TES) and esophageal speakers. In addition a control group of normal talkers was included. Audio recordings of 24 Spanish words produced by each speaker were analyzed using CSL (Kay Elemetrics). Results showed that F1, F2, and vowel duration of alaryngeal speakers differ significantly from normal values. In general, laryngectomized patients produce vowels with higher formant frequencies and longer durations than the group of laryngeal subjects. Thus, the data indicate modifications either in the frequency or temporal domain, following the same tendency found in previous studies with English-speaking laryngectomized speakers.

In this paper, I address the problem of including diphthong vowels into a Dispersion Theory (Flemming 2004) framework. First, I review the main aspects of Dispersion Theory in Flemming (2004), which gives an analysis of vowel inventories using a perception-based account of contrast, but noticeably omits diphthongs, which–while different from monophthongs–are highly productive, contrastive members of vowel inventories. Next, in order to correctly represent and incorporate diphthongs, I discuss acoustic properties of diphthongs and their presence in vowel inventories cross-linguistically. Diphthongs are compared to the monophthong inventory using production data to assess their relative positions in the vowel space. The English vowel production data should reflect the language-specific constraint ranking of *Effort with the maximum contrast and minimum distance constraints as predicted in Flemming's theory.                To derive diphthongs, Flemming (2004)’s constraints as well as additional constraints from Minkova & Stockwell (2003) are used to account for the distance between the two offset targets. An additional constraint is proposed to account for the strong preference in the English production data to centralize the onset targets. Derivations for individual diphthong productions compared to possible surrounding candidates are provided in the analysis.

The present study examines the acoustic properties of infant-directed speech (IDS) as compared to adult-directed speech (ADS) in Norwegian parents of 18-month-old toddlers, and whether these properties relate to toddlers’ expressive vocabulary size. Twenty-one parent- toddler dyads from Tromsø, Northern Norway participated in the study. Parents (16 mothers, 5 fathers), speaking a Northern Norwegian dialect, were recorded in the lab reading a storybook to their toddler (IDS register), and to an experimenter (ADS register). The storybook was designed for the purpose of the study, ensuring identical linguistic contexts across speakers and registers, and multiple representations of each of the nine Norwegian long vowels. We examined both traditionally reported measures of IDS: pitch, pitch range, vowel duration and vowel space expansion, but also novel measures: vowel category compactness and vowel category distinctiveness. Our results showed that Norwegian IDS, as compared to ADS, had similar characteristics as in other languages: higher pitch, wider pitch range, longer vowel duration, and expanded vowel space area; in addition, it had less compact vowel categories. Further, parents’ hyper-pitch, that is, the within-parent increase in pitch in IDS as compared to ADS, and vowel category compactness in IDS itself, were positively related to toddlers' vocabulary. Our results point towards potentially facilitating roles of parents’ increase in pitch when talking to their toddler and of consistency in vowel production in early word learning.

Mandarin Vowels

The present study aims to document the developmental profile of static and dynamic acoustic features of vowel productions in monolingual Mandarin-speaking children aged between three and six years in comparison to adults. Twenty-nine monolingual Mandarin children and 12 native Mandarin adults were recorded producing ten Mandarin disyllabic words containing five monophthongal vowel phonemes /a i u yɤ/. F1 and F2 values were measured at five equidistant temporal locations (the 20–35–50–65–80% points of the vowel's duration) and normalized. Scatter plots showed clear separations between vowel categories although the size of individual vowel categories exhibited a decreasing trend as the age increased. This indicates that speakers as young as three years old could separate these five Mandarin vowels in the acoustic space but they were still refining the acoustic properties of their vowel production as they matured. Although the tested vowels were monophthongs, they were still characterized by distinctive formant movement patterns. Mandarin children generally demonstrated formant movement patterns comparable to those of adult speakers. However, children still showed positional variation and differed from adults in the magnitudes of spectral change for certain vowels. This indicates that vowel development is a long-term process which extends beyond three years of age.
