Focus strategies in chadic : the case of tangale revisited

We argue that the standard focus theories reach their limits when confronted with the focus systems of the Chadic languages. The backbone of the standard focus theories consists of two assumptions, both called into question by the languages under consideration. Firstly, it is standardly assumed that focus is generally marked by stress. The Chadic languages, however, exhibit a variety of different devices for focus marking. Secondly, it is assumed that focus is always marked. In Tangale, at least, focus is not marked consistently on all types of constituents. The paper offers two possible solutions to this dilemma

Integrated approaches to prosodic word prediction for Chinese TTS

We focus on integrated prosodic word prediction for Chinese TTS. To avoid the problem of inconsistency between lexical words and prosodic words in Chinese, lexical word segmentation and prosodic word prediction are taken as one process instead of two independent tasks. Furthermore, two word-based approaches are proposed to drive this integrated prosodic word prediction: The first one follows the notion of lexicalized hidden Markov models, and the second one is borrowed from unknown word identification for Chinese. The results of our primary experiment show these integrated approaches are effective.published_or_final_versio

Speech rhythm: a metaphor?

Is speech rhythmic? In the absence of evidence for a traditional view that languages strive to coordinate either syllables or stress-feet with regular time intervals, we consider the alternative that languages exhibit contrastive rhythm subsisting merely in the alternation of stronger and weaker elements. This is initially plausible, particularly for languages with a steep ‘prominence gradient’, i.e. a large disparity between stronger and weaker elements; but we point out that alternation is poorly achieved even by a ‘stress-timed’ language such as English, and, historically, languages have conspicuously failed to adopt simple phonological remedies that would ensure alternation. Languages seem more concerned to allow ‘syntagmatic contrast’ between successive units and to use durational effects to support linguistic functions than to facilitate rhythm. Furthermore, some languages (e.g. Tamil, Korean) lack the lexical prominence which would most straightforwardly underpin prominence alternation. We conclude that speech is not incontestibly rhythmic, and may even be antirhythmic. However, its linguistic structure and patterning allow the metaphorical extension of rhythm in varying degrees and in different ways depending on the language, and that it is this analogical process which allows speech to be matched to external rhythms

An overview of theories of the syntax-phonology interface

This article is intended as a critical survey of the phonological theories of the syntax-phonology interface. These theories can be divided into two main groups, according to the role they attribute to syntactic representations in creating phonological domains. On the one hand there is the Direct Reference Theory, which claims that phonological operations are directly sensitive to syntactic information, in terms of relations of c-command or m-command (i.e., government) holding between the elements participating in phonological processes. On the other, there is the Prosodic Hierarchy Theory of Prosodic Phonology, which defends the view that syntactic and phonological representations are not isomorphic and that there is a distinct level of representation called Prosodic Structure which contains a hierarchically organized set of prosodic constituents. These constituents are built from syntactic structure by a finite set of parameterized algorithms, and phonological processes refer to prosodic constituents rather than to syntactic constituents. Elordieta (1997, 1999) proposes that certain phonological phenomena may be specified to apply in the domains or constituents formed by functional and lexical heads related by feature checking. Seidl's (2001) Minimal Indirect Reference Theory claims that syntactic relationships such as theta-domains determine phonological constituency at the phrasal level. Another important, more recent view is the one that maintains that spellout domains (that is, all the material included in a syntactic phase except for the head of the phase and elements in the specifier of that phase) are interpreted as phonological constituents in PF

Correspondence in OT syntax and minimal link effects

The aim of this paper is the exploration of an optimality theoretic architecture for syntax that is guided by the concept of "correspondence": syntax is understood as the mechanism of "translating" underlying representations into a surface form. In minimalism, this surface form is called "Phonological Form" (PF). Both semantic and abstract syntactic information are reflected by the surface form. The empirical domain where this architecture is tested are minimal link effects, especially in the case of "wh"-movement. The OT constraints require the surface form to reflect the underlying semantic and syntactic representations as maximally as possible. The means by which underlying relations and properties are encoded are precedence, adjacency, surface morphology and prosodic structure. Information that is not encoded in one of these ways remains unexpressed, and gets lost unless it is recoverable via the context. Different kinds of information are often expressed by the same means. The resulting conflicts are resolved by the relative ranking of the relevant correspondence constraints

Extending AuToBI to prominence detection in European Portuguese

This paper describes our exploratory work in applying the Automatic ToBI annotation system (AuToBI), originally developed for Standard American English, to European Portuguese. This work is motivated by the current availability of large amounts of (highly spontaneous) transcribed data and the need to further enrich those transcripts with prosodic information. Manual prosodic annotation, however, is almost impractical for extensive data sets. For that reason, automatic systems such as AuToBi stand as an alternate solution. We have started by applying the AuToBI prosodic event detection system using the existing English models to the prediction of prominent prosodic events (accents) in European Portuguese. This approach achieved an overall accuracy of 74% for prominence detection, similar to state-of-the-art results for other languages. Later, we have trained new models using prepared and spontaneous Portuguese data, achieving a considerable improvement of about 6% accuracy (absolute) over the existing English models. The achieved results are quite encouraging and provide a starting point for automatically predicting prominent events in European Portuguese.info:eu-repo/semantics/publishedVersio

Prosodic reading and reading comprehension in university

This study was aimed at investigating the students’ English reading comprehension on the basis of the importance of prosodic reading in university level by first, measuring the levels of reading prosody and reading comprehension, characterizing the acoustic characteristics produced by the students, and at last associating the first variable to the second variable. Prosodic reading levels were measured by using Multidimensional Fluency Scale, containing four dimensions. To explore the six types of syntactically complex structures produced by the students orally, this study conducted a descriptive analysis, only focused on some features. The findings showed that the students experienced moderate level of reading prosody and reading comprehension. Also, it could be reported that a significant correlation was found between the two variables. The study reported that prosodic reading contributed to reading comprehension with r-obtained .538. A thorough analysis explained that some other related predictors influenced students’ comprehension, like difficulties in recognizing the vocabulary, lack of knowledge to review the four types of sentences, and the length of the passage. Among four dimensions, only pace and expression & volume did contribute to reading comprehension much. Different pause structures produced by the students and the native speakers were clearly identified. This was shown as many students had a long pause and sound hesitate due to their inability to decode the words. Moreover, most of them could not comprehend the sentence structure of the text, when to pause, which words were needed to be stressed, and the intonation used. As a result, they read in a two-three phrases and declined to notice where the endings of sentences and clauses were definitely stated. These results confirmed that pause structure commits as a pivotal factor in determining students’ reading comprehension

Prosodic Focus Within and Across Languages

The fact that purely prosodic marking of focus may be weaker in some languages than in others, and that it varies in certain circumstances even within a single language, has not been commonly recognized. Therefore, this dissertation investigated whether and how purely prosodic marking of focus varies within and across languages. We conducted production and perception experiments using a paradigm of 10-digit phone-number strings in which the same material and discourse contexts were used in different languages. The results demonstrated that prosodic marking of focus varied across languages. Speakers of American English, Mandarin Chinese, and Standard French clearly modulated duration, pitch, and intensity to indicate the position of corrective focus. Listeners of these languages recognized the focus position with high accuracy. Conversely, speakers of Seoul Korean, South Kyungsang Korean, Tokyo Japanese, and Suzhou Wu produced a weak and ambiguous modulation by focus, resulting in a poor identification performance. This dissertation also revealed that prosodic marking of focus varied even within a single language. In Mandarin Chinese, a focused low/dipping tone (tone 3) received a relatively poor identification rate compared to other focused tones (about 77% vs. 91%). This lower identification performance was due to the smaller capacity of tone 3 for pitch range expansion and local dissimilatory effects around tone 3 focus. In Seoul Korean, prosodic marking of focus differed based on the tonal contrast (post-lexical low vs. high tones). The identification rate of high tones was twice as high than that of low tones (about 24% vs. 51%), the reason being that low tones had a smaller capacity for pitch range expansion than high tones. All things considered, this dissertation demonstrates that prosodic focus is not always expressed by concomitant increased duration, pitch, and intensity. Accordingly, purely prosodic marking of focus is neither completely universal nor automatic, but rather is expressed through the prosodic structure of each language. Since the striking difference in focus-marking success does not seem to be determined by any previously-described typological feature, this must be regarded as an indicator of a new typological dimension, or as a function of a new typological space
