English lexical stress is multidimensional in nature and acoustically related to combination of fundamental frequency (F0), duration, intensity and vowel quality. Errors in any or all of these correlates could interfere with perception of the stress contrast, but it is unknown which correlates are most difficult for Bengali speakers to acquire. This study compares the use of these correlates in...

An automatic method to assign lexical stress in Italian from a written text is presented here. This method is based on specific morphological properties of the Italian morphemes, which can only be stressed on the last or the penul timate syllable. Using a morphological analyzer and a morpheme database, the assignment program attempts to analyze each entry into a morpheme followed by one or more...

This paper examines the effects of lexical stress on intensity and duration in Persian both in the presence of the intonational prominence contrast and in the abstraction from the compounding accent condition. A production study was conducted in which 10 speakers produced Persian lexical and reiterant disyllabic minimal stress pairs spoken with and without an accent in a fixed carrier sentence....

In the present study we investigated the effect of semantic context on the perception of words that differ only in the lexical stress pattern. Our study was based on the disyllabic German word AUGUST. Depending on whether the lexical stress is on the first or the second syllable the word refers to either a name or a month. By means of a forced-choice identification experiment we tested to what ...

This study deals with acoustic phonetic modelling in HMM based continuous speech recognition. Context dependent phone models were derived by a decision tree clustering algorithm. In particular, lexical stress was introduced as a clustering variable in addition to the phonetic context. The parameter sharing model was extended by tying HMM states across different target phones. For instance, one ...

The aim of this research is to examine the role of the acoustic correlates of lexical stress in the integration of accentual information in French speakers. A shape/pseudoword matching task is used, as it implies not only a low-level acoustic processing, but also a lexical processing. Results show, on the one hand, an influence of the accentual pattern in the perception of stress; on the other,...
