ARCA è l'archivio istituzionale ad accesso aperto della ricerca dell'Università Ca' Foscari Venezia e nasce nel 2014 con lo scopo di raccogliere, diffondere e conservare la produzione scientifica dell'Università. Costituisce di fatto il catalogo della ricerca di Ateneo.ARCA è un sistema Open Access: è non solo consultabile da tutti e visibile nei motori di ricerca, ma anche interoperabile con il portale cerCa. In questo modo vengono valorizzate la produzione scientifica dell'Ateneo e la visibilità dei ricercatori.
EnglishA grammatical component to supply information to a text-to-speech system is presented. It is composed of four modules: a lexicon, a morphological recognizer, a syntactic preanalyzer, a parser. The parser is composed of a bottom-up algorithm implementing a context-free grammar for Italian simply as Recursive Transition Networks (RTN). No conditions are introduced on the arcs: this will constitute the topic of future work. The paper deals extensively with Fo contours and focus assignment rules in Italian by introducing Pierrehumbert's notational system [4]. We found that an Fo peak usually obtains in coincidence with the focussed syllable: this may be either realized as a fall or as a rise followed or preceded by a trailing/leading Fo movement in the opposite direction. The combination of the two tones High/Low and Low/High can appear also on other constituents - Phonological Words - but the steepness of the jump or dipping is remarkably inferior to the one occurring in focussed constituents.

| Abstract: | A grammatical component to supply information to a text-to-speech system is presented. It is composed of four modules: a lexicon, a morphological recognizer, a syntactic preanalyzer, a parser. The parser is composed of a bottom-up algorithm implementing a context-free grammar for Italian simply as Recursive Transition Networks (RTN). No conditions are introduced on the arcs: this will constitute the topic of future work. The paper deals extensively with Fo contours and focus assignment rules in Italian by introducing Pierrehumbert's notational system [4]. We found that an Fo peak usually obtains in coincidence with the focussed syllable: this may be either realized as a fall or as a rise followed or preceded by a trailing/leading Fo movement in the opposite direction. The combination of the two tones High/Low and Low/High can appear also on other constituents - Phonological Words - but the steepness of the jump or dipping is remarkably inferior to the one occurring in focussed constituents. |
