Elision of /h, ?/ in the Shirazi Dialect of Persian (SHDP) : an optimality theory based analysis
(2010)
Until recently, many researchers have shown interest in studying lenitions, which are examples of the most common universal types of phonological processes. Elision of laryngeals (glottal fricative /h/ and glottal stop /?/) is one of the most common phonological alternations exhibited in the Shirazi dialect of Persian (SHDP) which to the knowledge of the researchers, has not been studied to date. This paper seeks to provide a description of the facts about this common phonological alternation in the addressed regional dialect of Persian and points out some main differences between the behavior of these processes in SHDP and Standard Persian (SP). The analysis is cast in an Optimal Theoretic (OT) framework (McCarthy and Prince 1995, 2001), which holds that linguistic forms are the outcome of interaction among violable universal constraints. The present study shows that the addressed processes of consonant deletion in SHDP are restricted by syllabic position and are conditioned by coda position, intervocalic position or consonant clusters. They are usually blocked in the onset, but there are cases where reduction is allowed in the onset of the stressed syllable. Thus, the study adds SHDP to the list of languages which permit lenition in the onset of the stressed syllable. The addressed processes of elision are always blocked in word-initial position and laryngeal elision is always followed by Compensatory lengthening (CL), even after deletion from the onset of the stressed syllable.

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.
This article deals with the Tashlhiyt dialect of Berber (henceforth TB) spoken in the southern part of Morocco. In TB, words may consist entirely of consonants without vowels and sometimes of only voiceless obstruents, e.g. tft#tstt "you rolled it (fem)". In this study we have carried out acoustic, video-endoscopic and phonological analyses to answer the following question: is schwa, which may function as syllabic, a segment at the level of phonetic representations in TB? Video-endoscopic films were made of one male native speaker of TB, producing a list of forms consisting entirely of voiceless obstruents. The same list was produced by 7 male native speakers of TB for the acoustic analysis. The phonological analysis is based on the behaviour of vowels with respect to the phonological rule of assibilation. This study shows the absence of schwa vowels in forms consisting of voiceless obstruents.
In this study, cross-dialectal variation in the use of the acoustic cues of VOT and F0 to mark the laryngeal contrast in Korean stops is examined with Chonnam Korean and Seoul Korean. Prior experimental results (Han & Weitzman, 1970; Hardcastle, 1973; Jun, 1993 &1998; Kim, C., 1965) show that pitch values in the vowel onset following the target stop consonants play a supplementary role to VOT in designating the three contrastive laryngeal categories. F0 contours are determined in part by the intonational system of a language, which raises the question of how the intonational system interacts with phonological contrasts. Intonational difference might be linked to dissimilar patterns in using the complementary acoustic cues of VOT and F0. This hypothesis is tested with 6 Korean speakers, three Seoul Korean and three Chonnam Korean speakers. The results show that Chonnam Korean involves more 3-way VOT and a 2-way distinction in F0 distribution in comparison to Seoul Korean that shows more 3-way F0 distribution and a 2-way VOT distinction. The two acoustic cues are complementary in that one cue is rather faithful in marking 3-way contrast, while the other cue marks the contrast less distinctively. It also seems that these variations are not completely arbitrary, but linked to the phonological characteristics in dialects. Chonnam Korean, in which the initial tonal realization in the accentual phrase is expected to be more salient, tends to minimize the F0 perturbation effect from the preceding consonants by taking more overlaps in F0 distribution. And a 3-way distribution of VOT in Chonnam Korean, as compensation, can be also understood as a durational sensitivity. Without these characteristics, Seoul Korean shows relatively more overlapping distribution in VOT and more 3-way separation in F0 distribution.
