In an acoustic study, the influence of stop type, speaker age, and variety on the production of pre- and post-aspiration was analyzed in isolated words produced by 24 speakers of a Western and 24 of an Eastern variety, both divided into two age groups. The results confirmed previous findings of a sound change from pre- to post-aspiration in both varieties. Velar stops showed the longest, bilabials the shortest, and dental stops intermediate pre- and post-aspiration durations. The observed universal VOT-pattern was not found for younger Western Andalusian speakers who showed a particularly long VOT in /st/-sequences. A perception experiment with the same subjects as listeners showed that post-aspiration was used as a cue for distinguishing the minimal pair /pata/-/pasta/ by almost all listeners. Production-perception comparisons suggested a relationship between production and perception: subjects who produced long post-aspiration were also more sensitive to this cue. In sum, the results suggest that the sound change has first been actuated in the dental context, possibly due to a higher perceptual prominence of post-aspiration in this context, and that post-aspirated stops in Andalusian Spanish are on their way to being phonologized.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"7 1","pages":"1-36"},"PeriodicalIF":1.5,"publicationDate":"2016-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70691200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Resyllabification Reconsidered: On the Durational Properties of Word-Final /s/ in Spanish","authors":"Patrycja Strycharczuk, Martin Kohlberger","doi":"10.5334/LABPHON.5","DOIUrl":"https://doi.org/10.5334/LABPHON.5","url":null,"abstract":"Word-final consonants in Spanish are commonly assumed to undergo resyllabification across a word boundary before a following vowel, e.g., /los#otros/ 'the others' is realised as [lo.so.tros]. However, in many dialects of Spanish, word-final pre-vocalic consonants (‘derived onsets’) pattern phonologically with canonical codas and distinctly from canonical onsets. This property of derived onsets has been the subject of much interest in the phonological literature, and has led some linguists to question whether resyllabification indeed applies in all Spanish dialects. In this paper, we evaluate evidence for resyllabification based on acoustic data from 11 speakers of Peninsular Spanish. The results show that word-final pre-vocalic /s/ has increased duration compared to coda /s/, but at the same time, it is shorter compared to word-initial or word-medial pre-vocalic /s/. This result challenges an analysis where derived onsets become phonologically indistinguishable from canonical onsets. We consider an alternative in the form of partial resyllabification, and we further discuss the role of the syllable as a relevant unit in explaining /s/-sandhi in Spanish.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"7 1","pages":"1-24"},"PeriodicalIF":1.5,"publicationDate":"2016-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70691735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Word-types are often tacitly defined as phonologically unique words. Yet, an explicit test of this definition is lacking, and natural language patterning suggests that word meaning could also act as a cue to word-type status. This possibility was tested in a statistical phonotactic learning experiment in which phonological and semantic properties of word-types varied. During familiarization, the learning targets-word-medial consonant sequences-were instantiated either by four related word-types or by just one word-type (the experimental frequency factor). The expectation was that more word-types would lead participants to generalize the target sequences. Regarding semantic cues, related word-types were either associated with different referents or all with a single referent. Regarding phonological cues, related word-types differed from each other by one, two, or more phonemes. At test, participants rated novel wordforms for their similarity to the familiarization words. When participants heard four related word-types, they gave higher ratings to test words with the same consonant sequences, irrespective of the phonological and semantic manipulations.

Natural speech, in contrast, occurs in a variety of communicative contexts where speakers and hearers dynamically adjust their speech to fit their needs. The present paper demonstrates that phonologically informed analysis of specialized speech registers, such as infant-directed speech, can reveal specific ways segmental and supra-segmental aspects of phonology are modulated dynamically to accommodate the specific communicative needs of speakers and hearers. Data for the analyses come from a corpus of Japanese mothers’ spontaneous speech directed to their infant child (infant-directed speech, IDS) and an adult (adult-directed speech, ADS), as well as read speech (RS). The speech samples in the corpus are annotated with segmental, morphological, and intonational information. We will show that the way intonation is exaggerated in Japanese IDS reflects the intonational structure of Japanese, which is different from that of English. We will also demonstrate that rules of phonological grammar, such as devoicing of high vowels and non-high vowels in Japanese, can be differently affected by the needs of the speaker to accommodate the specific characteristics of the listener.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"6 1","pages":"281 - 303"},"PeriodicalIF":1.5,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67024999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We selected a small part of this corpus – interviews of 10 elderly speakers – and conducted multiparametric F0 and duration measurements, focusing on nuclear rising-falling pitch accent patterns. We found strong evidence for a phonological pitch-accent distinction that relies on the difference between a pointed and a plateau-shaped F0 peak. We suggest that the two pitch accents be represented as L+H* and H*+L, and we discuss our findings with regard to possible communicative functions, implications for intonational typology, and the trade-off between F0 range and F0 peak extension in conveying pitch height.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"6 1","pages":"433 - 468"},"PeriodicalIF":1.5,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67025048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of word frequency on vowel duration and the lexical diffusion of long-vowel shortening are also examined. The findings confirm the observation made in the previous literature that the vowel length contrast is on its way out in the language, and that this sound change is nearing completion. We also find a significant effect of frequency on long-vowel duration: other things being equal, these vowels are shorter in high-frequency words than in low-frequency words. The rate of change does not differ significantly depending on the frequency of words apart from the high-frequency words reaching the endpoint of change and bottoming out in the change earlier than mid- and low-frequency words. The observed frequency effect is compatible with a model in which the frequency effect on duration comes from on-line factors that affect phonetic implementation of speech sounds, along with an across-the-board lenition bias that drives the sound change, not from stored tokens of word-specific variants.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"6 1","pages":"469 - 503"},"PeriodicalIF":1.5,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67025049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Workers recruited in a crowdsourcing marketplace, because of their varying levels of commitment and education, make more mistakes than workers in a controlled laboratory setting. Methods for compensating transcriber mistakes are desirable because, with such methods available, crowdsourcing has the potential to significantly increase the scale of experiments in laboratory phonology. This paper provides a brief tutorial on statistical learning theory, introducing the relationship between dataset size and estimation error, then presents a theoretical description and preliminary results for two new methods that control labeler error in laboratory phonology experiments. First, we discuss the method of crowdsourcing over error-correcting codes. In the error-correcting-code method, each difficult labeling task is first factored, by the experimenter, into the product of several easy labeling tasks (typically binary). Factoring increases the total number of tasks, nevertheless it results in faster completion and higher accuracy, because workers unable to perform the difficult task may be able to meaningfully contribute to the solution of each easy task. Second, we discuss the use of explicit mathematical models of the errors made by a worker in the crowd. In particular, we introduce the method of mismatched crowdsourcing, in which workers transcribe a language they do not understand, and an explicit mathematical model of second-language phoneme perception is used to learn and then compensate their transcription errors. Though introduced as technologies that increase the scale of phonology experiments, both methods have implications beyond increased scale. The method of easy questions permits us to probe the perception, by untrained listeners, of complicated phonological models; examples are provided from the prosody of English and Hindi. The method of mismatched crowdsourcing permits us to probe, in more detail than ever before, the perception of phonetic categories by listeners with a different phonological system.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"52 1","pages":"381 - 431"},"PeriodicalIF":1.5,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67025046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study examines how the seemingly successful perceptual identification of voicing varies across stimulus items recorded in reading vs. non-reading procedures and with and without full minimal pairs present in the experimental list. Results of a series of identification tasks reveal that Russian listeners’ identification responses are more in line with underlying voicing for the stimuli recorded during word-reading and with minimal pairs included among the experimental items. This shows that voicing judgments are strongly influenced by the acoustic differences produced when speakers encounter orthographic forms or lexical competition. At the same time, perceptual neutralization is also not complete for the items recorded without such exposure, which indicates that listeners’ ability to recover underlying voicing is not limited to the production contexts involving written forms or minimal pairs.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"46 1","pages":"147 - 165"},"PeriodicalIF":1.5,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67024989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are claims that it is not aerodynamically possible to open the velum for nasalization while maintaining frication noise. We present aerodynamic data from 14 native Scottish Gaelic speakers to determine how the posited nasalized fricatives in this language are realized. Most tokens demonstrate loss of nasalization, but nasalization does occur in some contexts without aerodynamic conflict, e.g., nasalization with the consonant realized as an approximant, nasalization of [h̃], nasalization on the preceding vowel, or sequential frication and nasalization. Furthermore, a very few tokens do contain simultaneous nasalization and frication with a trade-off in airflow. We also present perceptual evidence showing that Gaelic listeners can hear this distinction slightly better than chance. Thus, instrumental data from one of the few languages in the world described as having nasalized fricatives confirms that the claimed sounds are not made by producing strong nasalization concurrently with clear frication noise. Furthermore, although speakers most often neutralize the nasalization, when they maintain it, they do so through a variety of phonetic mechanisms, even within a single language.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"6 1","pages":"197 - 241"},"PeriodicalIF":1.5,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67024993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such patterns always involve comparisons between words in the same morphological paradigm (e.g., singular and plural forms with the same stem). The lone exception to this generalization is Ichimura (2006), who argues that a nasal contraction pattern in Japanese is blocked by potential homophony between verbs with different stems. We present experimental evidence that homophony avoidance is not part of the correct synchronic description of the environment in which this pattern applies; rather, nasal contraction does not productively delete stem-final vowels. However, homophony avoidance does appear to affect the probability with which contraction applies. We conclude that homophony avoidance affects phonological behavior, but that absolute homophony-related blocking is restricted to morphological paradigms.","PeriodicalId":45128,"journal":{"name":"Laboratory Phonology","volume":"6 1","pages":"167 - 195"},"PeriodicalIF":1.5,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/lp-2015-0006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67024991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
