One of the central aims in research on anaphora is to discover the factors that determine the choice of referential expressions in discourse. Ariel (1988; 2001) offers an Accessibility Scale where referential expressions, including demonstratives, are categorized according to the values of anaphoric (i.e. textual) distance that each of these has in relation to its antecedent. The aim of this paper is to test Ariel’s (1988; 1990; 2001) claim that the choice to use proximal or distal anaphors is mainly determined by anaphoric distance. This claim is investigated in relation to singular demonstratives in a corpus of Classical Arabic (CA) prose texts by using word count to measure anaphoric distance. Results indicate that anaphoric distance cannot be taken as a consistent or reliable determinant of how anaphors are used in CA, and so Ariel’s claim is not supported by the results of this study. This also indicates that the universality of anaphoric distance, as a criterion of accessibility, is defied.

This paper presents an acoustic phonetic study of Polish V#V sequences designed to shed light on the phonological representation of glottal marking. Independent phonological evidence from Polish suggests that initial vowels contain an "empty onset" that may be realized as glottal marking. The results of the experiment suggest that glottal marking in Polish is quite robust, and may be realized by increases in spectral balance. In the Onset Prominence environment, the "empty onset" is derived from phonetic principles, realized as specification for the Vocalic Onset layer of structure. VO parameter settings capture important ambiguities in speech perception and allow for a unified analysis of glottal marking, distributional restrictions on Polish vowels, and ambiguities underlying palatalization processes.

The use of large speech corpora in phonetic research depends to a great extent on the availability and quality of phonetic segmentation and transcriptions. As a rule, the best quality of segmentation is achieved by human transcribers who perform time-consuming and tedious manual work. However, tools for automatic segmentation exploiting typically HMM-based forced alignment methods have been developed for different languages. In recent years, two automatic systems as free online services have become available for Estonian: (1) the system developed at Tallinn University of Technology (https://phon.ioc.ee/dokuwiki/doku.php?id=projects:tuvastus:est-align.et), and (2) the multi-lingual tool WebMAUS (https://clarin.phonetik.uni-muenchen.de/BASWebServices/). In this study we evaluate the performance of the two systems against human transcribers. The test set includes Estonian read speech produced by: (1) four L1 adult subjects, (2) six L1 adolescents, and (3) four L2 adult subjects. The reference segmentation data including 27 sentences from L1 subjects and 10 sentences from the other subjects were produced manually as Praat textgrid files with two tiers (word-level orthographic and phoneme-level SAMPA transcription); the automatic systems have produced similar textgrid files. In total, 1179 word boundaries and 5050 phone boundaries were compared. The results show that both systems performed more accurately for L1 adult speech and were less accurate in the case of adolescent and L2 speech. While the TUT system outperformed WebMAUS in L1 adult speech, then in L1 adolescents and L2 speech WebMAUS produced more accurate results. Despite the deviations in phone boundaries, the durations of vowel and consonant segments measured from automatic and manual segmentations of L1 adult speech differ only marginally. This suggest that the accuracy of both automatic systems seems to be sufficient for speech technology needs and could also be used in acoustic studies of L1 adult speech. However, both systems need improvements in order to reach the accuracy of automatic segmentation tools available for English.
