This exercise explores the historical relationship between tone, aspiration, prefixes and stem initial consonants in Tibetan. (The stem-initial consonant is underlined in those words that have prefixes or initial clusters; [ts], [tsh], [tç], [tçh], etc., all count as single consonants.) Other phonetic developments are also explored.
Consonants exhibit more variation in their phonetic realization than is typically acknowledged, but that variation is linguistically constrained. Acoustic analysis of both read and spontaneous speech reveals that consonants are not necessarily realized with the manner of articulation they would have in careful citation form. Although the variation is wider than one would imagine, it is limited by the phoneme inventory. The phoneme inventory of the language restricts the range of variation to protect the system of phonemic contrast. That is, consonants may stray phonetically into unfilled areas of the language's sound space. Listeners are seldom consciously aware of the consonant variation, and perceive the consonants phonemically as in their citation forms. A better understanding of surface phonetic consonant variation can help make predictions in theoretical domains and advances in applied domains.
We measure face deformations during speech production using a motion capture system, which provides 3D coordinate data of about 60 markers glued on the speaker's face. An arbitrary orthogonal factor analysis followed by a principal component analysis (together called a guided PCA) of the data has showed that the first 6 factors explain about 90% of the variance, for each of our 3 speakers. The 6 derived factors, therefore, allow us to efficiently analyze or to reconstruct with a reasonable accuracy the observed face deformations. Since these factors can be interpreted in articulatory terms, they can reveal underlying articulatory organizations. The comparison of lip gestures in terms of data derived factors suggests that these speakers differently maneuver the lips to achieve contrast between /s/ and /R/. Such inter-speaker variability can occur because the acoustic contrast of these fricatives is shaped not only by the lip tube but also by cavities inside the mouth such as the sublingual cavity. In other words, these tube and cavity can acoustically compensate each other to produce their required acoustic properties.
Cet article propose une réflexion sur la manière dont la langue bàsàa (Bantu A 43 parlée au Cameroun) exprime la relativisation. En l’absence d’une classe grammaticale de pronoms relatifs la langue utilise la classe des démonstratifs. La stratégie démonstrative mise en place peut selon les cas, associer la classe des locatifs pour déterminer les degrés de définitude. La langue distingue également les relatives restrictives des relatives non-restrictives qui sont soit descriptives, soit emphatiques. Du point de vue prosodique, la fin de la relative en bàsàa coïncide avec une finale de Groupe Intonatif.
Símákonde is an Eastern Bantu language (P23) spoken by immigrant Mozambican communities in Zanzibar and on the Tanzanian mainland. Like other Makonde dialects and other Eastern and Southern Bantu languages (Hyman 2009), it has lost the historical Proto-Bantu vowel length contrast and now has a regular phrase-final stress rule, which causes a predictable bimoraic lengthening of the penultimate syllable of every Prosodic Phrase. The study of the prosody / syntax interface in Símákonde Relative Clauses requires to take into account the following elements: the relationship between the head and the relative verb, the conjoint / disjoint verbal distinction and the various phrasing patterns of Noun Phrases. Within Símákonde noun phrases, depending on the nature of the modifier, three different phrasing situations are observed: a modifier or modifiers may (i) be required to phrase with the head noun, (ii) be required to phrase separately, or (iii) optionally phrase with the head noun.

This paper offers an extensive analysis of the reflexes of the Proto-Indo-European word-initial cluster *sk- in Proto-Slavic. It is argued that the regular reflex of this cluster is the Proto-Slavic *x-, but that *sk- was analogously re-introduced in a great number of cases under the influence of prefixed forms and cases where forms with and without the so-called "s-mobile" co-existed in Slavic. This conclusion is in accordance with the fact that *x- < *sk- is far more common in derivationally isolated words that do not occur with prefixes.
While the perilinguistic child is endowed with predispositions for the categorical perception of phonetic features, their adaptation to the native language results from a long evolution from the end of the first year of age up to the adolescence. This evolution entails both a better discrimination between phonological categories, a concomitant reduction of the discrimination between within-category variants, and a higher precision of perceptual boundaries between categories. The first objective of the present study was to assess the relative importance of these modifications by comparing the perceptual performances of a group of 11 children, aged from 8 to 11 years, with those of their mothers. Our second objective was to explore the functional implications of categorical perception by comparing the performances of a group of 8 deaf children, equipped with a cochlear implant, with normal-hearing chronological age controls. The results showed that the categorical boundary was slightly more precise and that categorical perception was consistently larger in adults vs. normal-hearing children. Those among the deaf children who were able to discriminate minimal distinctions between syllables displayed categorical perception performances equivalent to those of normal-hearing controls. In conclusion, the late effect of age on the categorical perception of speech seems to be anchored in a fairly mature phonological system, as evidenced the fairly high precision of categorical boundaries in pre-adolescents. These late developments have functional implications for speech perception in difficult conditions as suggested by the relationship between categorical perception and speech intelligibility in cochlear implant children.
It has been hypothesized that sounds which are less perceptible are more likely to be altered than more salient sounds, the rationale being that the loss of information resulting from a change in a sound which is difficult to perceive is not as great as the loss resulting from a change in a more salient sound. Kohler (1990) suggested that the tendency to reduce articulatory movements is countered by perceptual and social constraints, finding that fricatives are relatively resistant to reduction in colloquial German. Kohler hypothesized that this is due to the perceptual salience of fricatives, a hypothesis which was supported by the results of a perception experiment by Hura, Lindblom, and Diehl (1992). These studies showed that the relative salience of speech sounds is relevant to explaining phonological behavior. An additional factor is the impact of different acoustic environments on the perceptibility of speech sounds. Steriade (1997) found that voicing contrasts are more common in positions where more cues to voicing are available. The P-map, proposed by Steriade (2001a, b), allows the representation of varying salience of segments in different contexts. Many researchers have posited a relationship between speech perception and phonology. The purpose of this paper is to provide experimental evidence for this relationship, drawing on the case of Turkish /h/ deletion.
