Human listeners use lexical stress for word segmentation and disambiguation. We look into using lexical stress for speech recognition by examining a Dutch-language corpus. We propose that different spectral features are needed for different phonemes and that, besides vowels, consonants should be taken into account.

The current study examined the acoustic cues to lexical stress produced by speakers with spastic dysarthria and healthy control speakers. Of particular interest was the effect of stress location, which represented whether lexical stress was on the first vs. second syllable of the word. Results suggest that speakers with dysarthria convey lexical stress differently than do control speakers. The ...

The acoustic realization of vowels with lexical stress generally differs substantially from their unstressed counterparts, which are more reduced in spectral quality, shorter in duration, weaker in intensity and tend to have a flatter spectral tilt. Therefore, in a continuous speech recognizer (CSR) it would appear profitable to train separate models for the stressed and unstressed variants of ...

To assign lexical stress when reading, the Greek reader can potentially rely on lexical information (knowledge of the word), visual–orthographic information (processing of the written diacritic), or a default metrical strategy (penultimate stress pattern). Previous studies with secondary education children have shown strong lexical effects on stress assignment and have provided evidence for a d...

The aim of this research is to examine whether French speakers are able to store and retrieve lexical stress information, using a task in which shapes and Spanish pseudowords are matched. The role of the acoustic correlates of lexical stress in the integration of the accentual information was also studied. Results do not seem to support the hypothesis of ‘stress deafness’.

Recently we reported that spoken stressed and unstressed primes differently modulate Event Related Potentials (ERPs) of spoken initially stressed targets. ERP stress priming was independent of prime-target phoneme overlap. Here we test whether phoneme-free ERP stress priming involves the lexicon. We used German target words with the same onset phonemes but different onset stress, such as MANdel...
