Aligning prosody and syntax in property grammars
نویسندگان
چکیده
We propose in this paper a new approach for representing the prosody/syntax interface. We use for this a particular formalism, called Property Grammars, in which all information is represented by means of constraints. We show how alignment constraints can implement such an interface. One of the interests of these constraints, in comparison with other approaches such as optimality theory, is the possibility of representing different information at the same level (allowing then a parallel treatment of prosody and syntax). This discussion is illustrated with the example of dislocated constructions.

Tree grammars as models of prosodic structure
The common ToBI system of transcription assumes a sequential model of prosody. Many linguists argue for a tree structure explaining the synchronization and interaction among prosodic units. Could tree grammars, used previously in syntax-based language modeling, be used to model prosodic trees? We present a method of converting sequential transcripts into trees, and then demonstrate that modelin...
متن کاملSSCC: A Software Tool Based on Extended Ordered Attribute Grammars
Attribute grammars are a formalism for specifying computations on syntax trees. SSCC (a Sufficiently Smart Compiler Compiler) is a practical attribute-grammar system based on a polynomial-time extension to Kastens’s ordered attribute grammars. The new class of attribute grammars is strictly larger than the class of ordered attribute grammars, and it retains the property that there is a polynomi...
متن کاملUsing an HPSG grammar for the generation of prosodic structures
In this paper, we report on an experiment showing how the introduction of prosodic information from detailed syntactic structures into synthetic speech leads to better disambiguation of structurally ambiguous sentences. Using modifier attachment (MA) ambiguities and subject/object fronting (OF) in German as test cases, we show that prosody which is automatically generated from deep syntactic in...
متن کاملImproving the Robustness of Prosody Dependent Language Modeling Based on Prosody Syntax Dependence
This paper presents a novel approach that improves the robustness of prosody dependent language modeling by leveraging the dependence between prosody and syntax. A prosody dependent language model describes the joint probability distribution of concurrent word and prosody sequences and can be used to provide prior language constraints in a prosody dependent speech recognizer. Robust Maximum Lik...
متن کاملAdvantages of Constituency: Computational Perspectives on Samoan Word Prosody
In this paper, we computationally implement and compare grammars of Samoan stress patterns that refer to feet and that refer only to syllables in Karttunen’s finite state formalization of Optimality Theory, and in grammars that directly state restrictions on surface stress patterns. The grammars are defined and compared in the highlevel language of xfst to engage closely with specific linguisti...
