Agreeing to disagree : constant non-alignment of speech gestures in dialogue

Numerous studies suggest that interlocutors in a dialogue align with each other in terms of their articulatory gestures. It is often suggested that this, first, is the consequence of an automatic tendency for imitation and, second, this fosters mutual understanding. Making use of online archives of media, it was tested whether alignment is hence inevitable. The focus was on the pronunciation of the German word. The standard pronunciation is, but speakers with a Swabian accent produce, acoustically reflected in the fricative spectra. We measured the spectra of fricatives in from interviewers while interviewing either a prominent German politician using the Swabian variant or an interviewee using the standard variant. Results showed neither an overall influence of the interviewees' pronunciation on the fricative realization by the interviewer nor a tendency to align over time for interviewer-interviewee pairs with different pronunciations. This shows that phonetic alignment in conversation is a more complex process than most current theories seem to suggest. Moreover, failure to align may not impede mutual understanding.peer-reviewe

The perception of English front vowels by North Holland and Flemish listeners: acoustic similarity predicts and explains cross-linguistic and L2 perception

We investigated whether regional differences in the native language (L1) influence the perception of second language (L2) sounds. Many cross-language and L2 perception studies have assumed that the degree of acoustic similarity between L1 and L2 sounds predicts cross-linguistic and L2 performance. The present study tests this assumption by examining the perception of the English contrast between /e{open}/ and /æ/ in native speakers of Dutch spoken in North Holland (the Netherlands) and in East- and West-Flanders (Belgium). A Linear Discriminant Analysis on acoustic data from both dialects showed that their differences in vowel production, as reported in and Adank, van Hout, and Van de Velde (2007), should influence the perception of the L2 vowels if listeners focus on the vowels' acoustic/auditory properties. Indeed, the results of categorization tasks with Dutch or English vowels as response options showed that the two listener groups differed as predicted by the discriminant analysis. Moreover, the results of the English categorization task revealed that both groups of Dutch listeners displayed the asymmetric pattern found in previous word recognition studies, i.e. English /æ/ was more frequently confused with English /e{open}/ than the reverse. This suggests a strong link between previous L2 word learning results and the present L2 perceptual assimilation patterns

Not all geminates are created equal : evidence from Maltese glottal consonants

Many languages distinguish short and long consonants or singletons and geminates. At a phonetic level, research has established that duration is the main cue to such distinctions but that other, sometimes language-specific, cues contribute to the distinction as well. Different proposals for representing geminates share one assumption: The difference between a singleton and a geminate is relatively uniform for all consonants in a given language. In this paper, Maltese glottal consonants are shown to challenge this view. In production, secondary cues, such as the amount of voicing during closure and the spectral properties of frication noises, are stronger for glottal consonants than for oral ones, and, in perception, the role of secondary cues and duration also varies across consonants. Contrary to the assumption that gemination is a uniform process in a given language, the results show that the relative role of secondary cues and duration may differ across consonants and that gemination may involve language-specific phonetic knowledge that is specific to each consonant. These results question the idea that lexical access in speech processing can be achieved through features.peer-reviewe

On the causes of compensation for coarticulation : evidence for phonological mediation

This study examined whether compensation for coarticulation in fricative-vowel syllables is phonologically mediated or a consequence of auditory processes. Smits (2001a) had shown that compensation occurs for anticipatory lip rounding in a fricative caused by a following rounded vowel in Dutch. In a first experiment, the possibility that compensation is due to general auditory processing was investigated using nonspeech sounds. These did not cause context effects akin to compensation for coarticulation, although nonspeech sounds influenced speech sound identification in an integrative fashion. In a second experiment, a possible phonological basis for compensation for coarticulation was assessed by using audiovisual speech. Visual displays, which induced the perception of a rounded vowel, also influenced compensation for anticipatory lip rounding in the fricative. These results indicate that compensation for anticipatory lip rounding in fricative-vowel syllables is phonologically mediated. This result is discussed in the light of other compensation-for-coarticulation findings and general theories of speech perception.peer-reviewe

The mental lexicon is fully specified : evidence from eye-tracking

Four visual-world experiments, in which listeners heard spoken words and saw printed words, compared an optimal-perception account with the theory of phonological underspecification. This theory argues that default phonological features are not specified in the mental lexicon, leading to asymmetric lexical matching: Mismatching input ("pin") activates lexical entries with underspecified coronal stops ('tin'), but lexical entries with specified labial stops ('pin') are not activated by mismatching input ("tin"). The eye-tracking data failed to show such a pattern. Although words that were phonologically similar to the spoken target attracted more looks than unrelated distractors, this effect was symmetric in Experiment 1 with minimal pairs ("tin"- "pin") and in Experiments 2 and 3 with words with an onset overlap ("peacock" - "teacake"). Experiment 4 revealed that /t/-initial words were looked at more frequently if the spoken input mismatched only in terms of place than if it mismatched in place and voice, contrary to the assumption that /t/ is unspecified for place and voice. These results show that speech perception uses signal-driven information to the fullest, as predicted by an optimal perception account.peer-reviewe

How are words reduced in spontaneous speech?

Words are reduced in spontaneous speech. If reductions are constrained by functional (i.e., perception and production) constraints, they should not be arbitrary. This hypothesis was tested by examing the pronunciations of high- to mid-frequency words in a Dutch and a German spontaneous speech corpus. In logistic-regression models the "reduction likelihood" of a phoneme was predicted by fixed-effect predictors such as position within the word, word length, word frequency, and stress, as well as random effects such as phoneme identity and word. The models for Dutch and German show many communalities. This is in line with the assumption that similar functional constraints influence reductions in both languages

Is vowel normalization independent of lexical processing?

The author wishes to thank James McQueen, Klaus Kohler, Randy Diehl, and an anonymous reviewer for comments on an earlier version of this article and Marloes van der Goot, Laurance Bruggeman, and Jet Sueters for running the experiments.Vowel normalization in speech perception was investigated in three experiments. The range of the second formant in a carrier phrase was manipulated and this affected the perception of a target vowel in a compensatory fashion: A low F2 range in the carrier phrase made it more likely that the target vowel was perceived as a front vowel, that is, with a high F2. Recent experiments indicated that this effect might be moderated by the lexical status of the constituents of the carrier phrase. Manipulation of the lexical status in the present experiments, however, did not affect vowel normalization. In contrast, the range of vowels in the carrier phrase did influence vowel normalization. If the carrier phrase consisted of mid-to-high front vowels only, vowel categories shifted only for mid-to-high front vowels. It is argued that these results are a challenge for episodic models of word recognition.peer-reviewe

How phonological reductions sometimes help the listener

In speech production, high-frequency words are more likely than low-frequency words to be phonologically reduced. We tested in an eye-tracking experiment whether listeners can make use of this correlation between lexical frequency and phonological realization of words. Participants heard prefixed verbs in which the prefix was either fully produced or reduced. Simultaneously, they saw a high-frequency verb and a low-frequency verb with this prefix—plus 2 distractors—on a computer screen. Participants were more likely to look at the high-frequency verb when they heard a reduced prefix than when they heard a fully produced prefix. Listeners hence exploit the correlation of lexical frequency and phonological reduction and assume that a reduced prefix is more likely to belong to a high-frequency word. This shows that reductions do not necessarily burden the listener but may in fact have a communicative function, in line with functional theories of phonology.peer-reviewe

Servant Leadership and Its Effect on Employee Job Satisfaction and Turnover Intent

Experts expect a shortage of more than 900,000 nurses by 2022, according to the United States Bureau of Labor Statistics Employment Projections. Turnover in nursing contributes significantly to the shortage and often results from poor leadership of nurse managers. The purpose of this quantitative study was to investigate how servant leadership behaviors affected the psychological state and behavioral response of staff nurses as reflected by job satisfaction and turnover intention. Specifically, the research question addressed whether servant leadership positively contributes to the psychological states and the behaviors of staff nurses leading to greater job satisfaction. The study design was correlational, nonexperimental, and cross-sectional. Use of a questions from existing surveys combined into a single survey, from 284 staff nurses at a Pennsylvania hospital, provided the data for the research. Correlation analysis determined the strength and direction of servant leadership constructs and the dependent variables of turnover intention and job satisfaction. Multiple linear regression analysis predicted the influence of job satisfaction and turnover intention, demonstrating a strong, positive correlation linking servant leadership behaviors, the psychological state of engagement and job satisfaction. The study contributed to filling the gap in health care management by providing a picture of how servant leadership behaviors influenced job satisfaction and retention of nursing staff. Implications for positive social change may lead hospital administrators to encourage the adoption of servant leadership behaviors, by nurse managers, resulting in greater staff nurse job satisfaction, improved patient quality outcomes, sustainable organizational financial success, and expanded community health
