Résumé :
The natural tendency for language variation, intensified by Spanish’s territorial growth, has driven sibilant changes and mergers across the Spanish-speaking world. This article aims to present an overview of the most significant processes undergone by sibilant /s/ in various Spanish-speaking areas: devoicing, weakening, aspiration, elision, and voicing. Geographically based phonetic variations, sociolinguistic factors, and Spanish language contact situations are considered in this study. The sibilant merger and its chronological development in modern Spanish, along with geographic expansion, have resulted in multiple contemporary dialectal variations. This historical lack of stability in these sounds has marked modern regional variations. Tracing and framing the sibilants’ geo-linguistic features has received much attention from scholars, resulting in sibilants being one of the most studied variables in Spanish phonetics. In this article, we provide a concise approach that offers the reader an updated sociolinguistic view of the modern cross-dialectal realizations of /s/. It is essential to study sibilant development to describe Spanish dialects, the differences between Transatlantic and Castilian varieties, and the speech features found in Spanish speaking communities in the Americas. Examining sibilance from different approaches with a representative variety of Spanish dialects as examples advances the importance of sociolinguistic phenomena to index language changes.

Résumé :
This study examines individual differences in producing the sibilant contrast in American English and the relation of those differences to 2 speaker characteristics: (a) use of a quantal biomechanical effect (called a "saturation effect") in producing the sibilants and (b) performance on a test of sibilant discrimination. Twenty participants produced the sibilants /s/ and /∫/ in normal-, clear-, and fast-speaking conditions. The degree to which the participants used a saturation effect in producing /s/ and /∫/ was assessed with a custom-made sensor that measured contact of the underside of the tongue tip with the lower alveolar ridge; such contact normally occurs during the production of /s/ but not /∫/. The acuteness of the participants' discrimination of the sibilant contrast was measured using the ABX paradigm and synthesized sibilants. Differences among speakers in the degree of acoustic contrast between /s/ and /∫/ that they produced proved related to differences among them in their use of contact contrastively and in their discriminative performance. The most distinct sibilant productions were obtained from participants who used contact in producing /s/ but not /∫/ and who had high discrimination scores. The participants who did not use contact differentially when producing the 2 sibilants and who also discriminated the synthetic sibilants less well produced the least distinct sibilant contrasts. Intermediate degrees of sibilant contrast were found with participants who used contact differentially or discriminated well. These findings are compatible with a model of speech motor planning in which goals for phonemic speech movements are in somatosensory and auditory spaces.

Résumé :
Purpose This study investigated vowel and sibilant productions in noise to determine whether responses to noise (a) are sensitive to the spectral characteristics of the noise signal and (b) are modulated by the contribution of vowel or sibilant contrasts to word discrimination. Method Vowel and sibilant productions were elicited during serial recall of three-word sequences that were produced in quiet or during exposure to speaker-specific noise signals. These signals either masked a speaker's productions of the sibilants /s/ and /ʃ/ or their productions of the vowels /a/ and /æ/. The contribution of the vowel and sibilant contrasts to word discrimination in a sequence was manipulated by varying the number of times that the target sibilant and vowel pairs occurred in the same word position in each sequence. Results Spectral noise effects were observed for both sibilants and vowels: Responses to noise were larger and/or involved to more acoustic features when the noise signal masked the acoustic characteristics of that phoneme class. Word discrimination effects were limited and consisted of only small increases in vowel duration. Interaction effects between noise and similarity indicated that the phonological similarity of sequences containing both sibilants and/or both vowels influenced articulation in ways not related to speech clarity. Conclusion The findings of this study indicate that sensorimotor control of speech exhibits some sensitivity to noise spectral characteristics. However, productions of sibilants and vowels were not sensitive to their importance in discriminating the words in a sequence. In addition, phonological similarity effects were observed that likely reflected processing demands related to the recall and sequencing of high-similarity words.

Résumé :
In this artiele I reanalyze sibilant inventories of Slavic languages by taking into consideration acoustic. perceptive and phonological evidence. The main goal of this study is to show that perception is an important factor which determines the shape of sibilant inventories. The improvement of perceptual contrast essentially contributes to creating new sibilant inventories by (i) changing the place of articulation of the existing phonemes (ii) merging sibilants that are perceptually very close or (iii) deleting them. It has also been shown that the symbol s traditionally used in Slavic linguistics corresponds to two sounds in the IP A system: it stands for a postalveolar sibilant (ʃ) in some Slavic languages, as e.g. Bulagarian, Czech, Slovak, some Serbian and Croatian dialects, whereas in others like Polish, Russian, Lower Sorbian it functions as a retroflex (ʂ). This discrepancy is motivated by the fact that ʃ is not optimal in terms of maintaining sufficient perceptual contrast to other sibilants such as s and ɕ. If ʃ occurs together with s (and sʲ) there is a considerable perceptual distance between them but if it occurs with ɕ in an inventory, the distance is much smaller. Therefore, the strategy most languages follow is the change from a postalveolar to a retroflex sibilant.

Résumé :
We analyze sibilant harmony in the Santiago Atitlán dialect of Tz’utujil (Mayan), a phenomenon that was briefly described by Dayley (1985). Novel data show that the obligatory harmony process (i) is asymmetrical (triggered only by [+ant] sibilants), (ii) progressive, and (iii) applies long-distance. Furthermore, we argue that the process is not stem-controlled. In contextualizing the phenomenon within the typology of sibilant harmony (Hansson 2010), we conclude that it is unique. Finally, we suggest that Santiago Tz’utujil sibilant harmony has been stable diachronically because the target segment /ʃ/ is always in the stressed syllable, thus being salient in the input during acquisition.

Résumé :
The devoicing of sibilants took place in Early Modern Spanish, a phenomenon which has been considered problematic to account for due to its occurrence context (medial intervocalic position). Traditional explanations invoked Basque influence or a structural reorganization in search for a more balanced system. However, phonetically based reasons were proposed by some scholars. This research is a preliminary attempt to support these proposals with experimental data from a comparative grammar perspective. The Catalan sibilant system, which is very similar to the Medieval Spanish one, is acoustically and perceptively studied in order to investigate the acoustic cues of voicing and to determine if devoicing is possible. Results indicate that (a) voicing relies mainly in the proportion of unvoiced frames of the segments, on its duration, and, to a lesser extent, on its intensity; (b) sibilant devoicing occurs in all voiced categories; (c) auditorily, confusion between voiced and voiceless segments can be attested for every sibilant pair, and (d) the misparsings are more common in affricate and in palatal sibilants, [d͡ʒ] being the most prone to be labelled as unvoiced. These findings prove that the historical process in Spanish could have a phonetic basis.

Résumé :
Sibilant harmony in Nkore-Kiga is an interesting problem case for agreement-based theories of harmony, particularly Agreement by Correspondence. Previous work reports that anteriority agreement is controlled by the rightmost sibilant in the stem, and also that the quality of a sibilant is allophonically determined by the following vowel. In such a system, it is impossible for surface-oriented agreement constraints to derive strictly right-to-left harmony. However, we show that Nkore-Kiga does not work in quite this way: sibilants are conditioned not allophonically, but by morphology. This allows the facts of this case to be explained within existing Agreement by Correspondence proposals.

Résumé :
Abstract Cross-linguistically, fricatives are the rarest types of rhotics, found in a few African and European languages (Ladefoged & Maddieson 1996) and as allophones in some Romance languages (Jesus & Shadle 2005; Recasens 2002; Bradley 2006; Colantoni 2006). Acoustic data from Nusu, phonotactic reasoning, and a cognate comparison demonstrate the presence of alveolar fricative rhotics in Tibeto-Burman. The Nusu rhotic appears in syllable-initial position as the first or second consonant and can be realized as alveolar approximants [ɹ] or [ɹʲ], non-sibilant voiced and voiceless fricatives [ɹ̝, ɹ̥], as well as voiced sibilant [ʐ]. In other studies on Nusu, these fricative rhotics have sometimes been reported as retroflex voiced sibilants (Sun & Lu 1986; Fu 1991), but intra-speaker and cross-variety comparison point to classification as rhotics. Evidence from other Tibeto-Burman languages suggests that alveolar fricative rhotics are not limited to Nusu. Together these data challenge the tradition of generally interpreting alveolar fricatives as sibilants.

O estudo dos sistemas de sibilantes do galego foi e segue a ser un dos puntos de maior interese para a lingüística galega por constituíren un terreo de profunda inestabilidade e pola dificultade da súa descrición. Neste artigo analízase, dende o enfoque da fonética acústica, o sistema de sibilantes de catro mulleres da localidade de Zas pertencentes a dous grupos de idade diferentes. Desta análise derívase que as mulleres de maior idade presentan un sistema dunha sibilante única, de realización apicoalveolar. Pola contra, no caso das mulleres máis novas, obsérvase un sistema non descrito anteriormente, formado por dúas unidades: a fricativa interdental xorda /θ/ e a sibilante apicoalveolar /s̺/, no que se mantén a despalatalización do /ʃ/ sen se tratar dunha fala seseante.

En el presente estudio, se analiza el ensordecimiento de las sibilantes /z/, /ʑ/ y /ʐ/ de una hablante nativa del polaco de la localidad de Gdynia. En el análisis fonológico, hemos seguido el modelo lineal, propuesto por Chomsky y Halle (1979), y el modelo autosegmental jerárquico de Nuñez-Cedeño (2014), ambos pertenecientes a la fonología generativa. Los resultados muestran que el ensordecimiento de sibilantes alveolares, alveopalatales y retroflejas ocurre en a) posición implosiva, seguidas por una obstruyente sorda, y b) a final de palabra. Asimismo, se encontró el proceso de ensordecimiento de la sibilante retrofleja /ʐ/ cuando esta es antecedida por una oclusiva sorda. Por otro lado, el análisis da cuenta de una condición en la que la secuencia de sibilante sonora final seguida de una oclusiva sonora sería necesaria para la conservación de la sonoridad. Finalmente, explicaremos los procesos observados mediante la formulación de tres reglas fonológicas.

Résumé :
Suomen kielen /s/-sibilantista on olemassa vähän etenkin lasten tuottamaa normiaineistoa ja akustisten mittausten tuloksia. Tämän pro gradu -tutkielman tarkoituksena oli kerätä normiaineistoa suomenkielisten lasten tuottamasta sibilantista sekä analysoida eri vokaalikontekstissa tuotettujen /s/-artikulaatioiden akustisia piirteitä. Lisäksi kiinnostuksen kohteena oli kahden eri ikäryhmän ja sukupuolten väliset erot /s/:n tuottamisessa. Tutkimusta varten kerättiin ääninäytteitä 20 suomenkieliseltä lapselta, joista 10 oli iältään 5–7-vuotiaita ja 10 9–11-vuotiaita. Molemmissa ikäryhmissä oli yhtä paljon tyttöjä ja poikia, ja lapset olivat kielellisesti tyypillisesti kehittyneitä. Lapset toistivat kehyslauseita, joissa /s/ esiintyi 12 eri vokaalikontekstissa. Kerätyt ääninäytteet segmentoitiin ja /s/-artikulaatiot analysoitiin akustisesti. Akustisessa analyysissa käytettiin hyväksi spektraalisia momentteja, joita ovat spektraalinen painopiste (M1), spektrin keskihajonta (M2), vinous (M3) ja huipukkuus (M4). Lisäksi /s/-artikulaatioista analysoitiin spektrihuipun sijainti ja artikulaation kesto. Sibilanttisegmentit arvioitiin myös visuaalisesti spektrogrammitarkastelussa. Tässä tutkimuksessa havaittiin, että suomenkielisten lasten /s/-artikulaatiossa esiintyy paljon variaatiota ja se on akustisilta ominaisuuksiltaan erilainen kuin englanninkielisten lasten tuottama /s/. Vokaalikonteksti vaikuttaa merkitsevästi /s/:n akustisiin piirteisiin, mikä tukee muiden tutkimusten havaintoja. Lasten tuottamia artikulaatioita tarkasteltaessa kävi ilmi, että joissakin toistoissa etenkin korkeassa vokaalikontekstissa frikaatiokohina katkesi keskellä sibilanttiartikulaatiota, mikä voi olla osoitus lasten artikulaatioelinten motorisesta kypsymättömyydestä. Tarkasteltaessa ryhmien välisiä eroja havaittiin, että ikäryhmien välillä löytyi eroa /s/:n keston, spektraalisen painopisteen ja spektrihuipun sijainnin suhteen. Myös tyttöjen ja poikien artikulaation välillä löytyi merkitsevä ero. Pojilla vokaalikonteksti vaikutti /s/:n ominaisuuksiin enemmän kuin tytöillä. Tuloksista voitiin päätellä, että /s/:n akustiset ominaisuudet muuttuvat vielä kouluvuosien aikana, etenkin pojilla. Tämä tutkimus auttaa osaltaan määrittelemään suomenkielisten lasten tuottaman /s/:n tyypillisiä piirteitä, joiden perusteella voidaan päätellä, kuuluuko jonkun lapsen artikuloima /s/ normaalivariaation piiriin, vai onko syytä aloittaa kuntoutus. Lisäksi on huomioitava, että artikulaatio muuttuu vielä kouluvuosien aikana, kun lapsi mukauttaa sibilantin tuoton fyysisiin muutoksiin. Jotta suomenkielisten lasten /s/-artikulaation akustisista piirteistä saataisiin tarkempi kuva, tulisi normiaineistoa kerätä tätä tutkimusta laajemmin eri ikäryhmiltä ja kattavasti koko Suomen alueelta.

This paper presents an Optimality-Theoretic analysis (Prince and Smolensky, 1993) of sibilant harmony in Navajo. This Optimality- Theoretic (OT) analysis uses correspondence theory (McCarthy and Prince, 1995) to account for changes in the [±anterior] feature in coronal segments in the verbal conjunct domain. Specifically, the place of articulation of the rightmost coronal fricative segment determines the place of articulation of all other coronal fricatives in the verbal conjunct domain via Ident, Agree and Max constraints. This OT analysis is innovative in that it posits a constraint that protects pronominal-argument morphemes from deletion.

Résumé :
L'objectif de cette thèse est de décrire de manière analytique le spectre du bruit de friction en mettant en évidence l'affiliation des pics spectraux aux cavités du conduit vocal, par le biais de la modélisation acoustique et avec l'aide des données IRM de 7 langues [30 locuteurs]. Les résultats sont les suivants : 1. La dispersion des sibilantes dans l'espace articulatoire dépend du système phonologique [contrastes [+/- antérieur], [+/- distribué], ou les deux]. En français [+/- antérieur], 7 locuteurs], la variation inter-individuelle est importante. 2. Cette variation est due à deux variantes articulatoires du /ʃ/ : (a) plutôt apical, comportant une cavité sublinguale, accompagné de protrusion labiale, et semblable au /ʂ/ polonais ; et [b] palatalisé, mettant en œuvre le bombement du dos de la langue, comparable au /ɕ/ polonais. L'équivalence acoustique des deux variantes est démontrée par une simulation acoustique systématique. 3. En polonais, où la différence articulatoire est phonémique, /ʂ/ est caractérisé par un pic ultra-bas [1,5-1,8 kHz], affilié à la cavité antérieure, d'après la simulation acoustique à l'aide de fonction d'aire réelles de deux locuteurs. 4. Les données articulatoires présentent systématiquement une constriction dentale étroite. D'après la modélisation acoustique, la protrusion labiale aurait comme effet d'abaisser la fréquence d'un formant affilié spécifiquement à la cavité labiale. En somme, la présence de deux constrictions étroites linguale et dentale rend possible le contrôle quasi indépendant d'au moins deux résonances. Cette spécificité garantit aux sibilantes un bruit distinctif qui permet d'expliquer la richesse de leurs inventaires

Résumé :
In binyan hitpa'el, the reflexive and reciprocal verbal conjugation in Modern Hebrew, the /t/ of the /hit-/ prefix categorically metathesizes with a following sibilant (/s/, /z/, /∫/, or /t⁀s/), giving forms like [histakel] instead of expected forms like *[hitsakel]. It has been theorized that this metathesis may be perceptual, serving to place the /-t-/ in prevocalic position where it can be better perceived by listeners, the direction of metathesis being the more common sibilant + stop sequence in Modern Hebrew (Hume 2004), or that it may be auditory, based on a tendency for the sibilant noise to decouple from the rest of the speech stream, resulting in listener confusion about the place of the sibilant within the word (Blevins & Garrett 2004). Based on data from a speech perception experiment using English speakers, who listened to masked stimuli similar to hitpa'el verbs, I argue that Blevins & Garrett (2004)'s account is correct, with English speaking listeners evincing a tendency to misperceive stop + sibilant sequences as sibilant + stop sequences, despite the higher frequency of stop + sibilant sequences in English.

Résumé :
Speech production in children with Down’s syndrome (DS) has been found to be variable and inconsistent. Errors are concentrated in consonants that are typically late developing, such as fricatives. It has been suggested that inconsistency in speech production in DS is a result of a motor speech deficit but there is little detailed articulatory evidence to support this claim. This study (with data from MRC grant ‘Assessment and Treatment of Impaired Speech Motor Control in Children with Down's syndrome’ (G0401388)) provides a detailed phonetic analysis of the voiceless sibilants /s/ and /ʃ/, in a group of young people with DS, by means of auditory and articulatory analysis. The aim of the study is to assess fine motor ability and articulation variability at word level production in a group of speakers with well-established difficulties in speech articulation. The study analysed data from 25 children with DS, 10 typically developing children and 8 adult speakers, recorded using EPG. Perceptual measures were compared with quantitative analyses of EPG data, along with visual analysis of articulation patterns based on a new set of articulation taxonomies. The data is presented by group and in the form of 5 case studies. The case studies provide a means to analyse the relationship between articulation and auditory information in detail and to compare these with supplementary motor control measures. The results show presence of atypical articulation patterns for speakers with DS for both perceptually acceptable tokens, and those in error. Higher levels of within-speaker articulation variability are presented in comparison to the TD control group. Further findings suggest presence of articulation patterns in the TD speakers previously unidentified in EPG studies. Similar to previous studies, the results find that speakers with DS are a highly variable group and that speakers display a combination of typical and atypical speech patterns, influenced by speech motor control difficulties.

A análise das consoantes fricativas sibilantes nas CSM partiu da consideração das possibilidades de representação e de variação gráfica para essas consoantes, através da comparação entre os manuscritos originais das cantigas do corpus. Em primeiro lugar, foi feito um mapeamento das ocorrências das consoantes fricativas sibilantes do corpus, levando-se em consideração sua posição na sílaba (se no onset ou na rima), tendo, como objetivo, apresentar o sistema das consoantes fricativas empregado pelos trovadores que compuseram as cantigas religiosas em galego-português. A análise do sistema consonantal do Português Arcaico (PA), especificamente no que concerne às fricativas sibilantes, foi embasada, principalmente, nas teorias fonológicas não lineares, especialmente os modelos de Geometria de Traços (CLEMENTS; HUME, 1995) e, para o Português Brasileiro (PB), Cagliari (1998a). A abordagem inicial dos dados, para estabelecer se há ou não oposição entre os sons representados pelos grafemas focalizados, foi tomada a partir do modelo estruturalista de Pike (1947), segundo a leitura que dele faz Cagliari (2002). O corpus de base, para o PA, foi constituído pelas CSM, que são a maior coleção de poemas religiosos em louvor de Santa Maria compostos em galego-português, mandada compilar por Afonso X (1121-1284), rei de Castela. A justificativa para a escolha de textos poéticos como corpus desta pesquisa deve-se ao fato de que, por meio da análise das rimas encontradas nas CSM, é possível obter pistas satisfatórias sobre a realização fônica de consoantes em momentos passados da língua, dos quais não se têm registros orais. Nesta pesquisa, optou-se por trabalhar com as cantigas religiosas porque estudos revelam que as...
The purpose of this study is to map the sibilant fricative consonants existing in the Cantigas de Santa Maria (CSM). The following are the fricative graphemes on which we focused: , , , , <ç>, , and . The analysis of the sibilant fricative consonants in the CSM started from the consideration of the representation and graphic variation possibilities for these consonants, by means of comparison among the original manuscripts of the cantigas contained in the corpus. First, the occurrence of sibilant fricative consonants on the corpus were mapped according to their position in the syllable (whether onset or on the rhyme), with the purpose of presenting the fricative consonant system employed by the troubadours who composed the religious cantigas in Galician-Portuguese. The analysis of the Archaic Portuguese (AP) consonantal system, specifically on what concerns the sibilant fricative consonants, was mainly based on non-linear phonological theories, specially the Feature Geometry models (CLEMENTS; HUME, 1995), and, for Brazilian Portuguese (BP), Cagliari (1998). In order to establish the existence or non-existence of opposition between the sounds represented by the focused graphemes, the initial data approach was employed based on Pike´s (1947) structuralist model, following Cagliari’s (2002) understanding. The base corpus for AP was comprised of the CSM, which are the largest collection of religious poems in praise of Saint Mary, composed in Galician-Portuguese, whose compilation was requested by Afonso X (1121-1284), king of Castile. The reason behind the selection of poetic texts as the corpus of this research lies in the fact that, through the analysis of the rhymes found in the CSM, it is possible to obtain satisfactory clues about the phonetic realization of consonants in past moments of the language, of which no oral records are available. For this research, we chose to work with religious cantigas because ...
