Metrical segmentation in Dutch: vowel quality or stress?

Area of Science:

• Psycholinguistics
• Speech Perception
• Phonology

Background:

• English listeners segment continuous speech using metrically strong syllables.
• Dutch and English share metrical properties but differ in acoustic salience and stress-vowel quality dependency.

Purpose of the Study:

• Investigate the metrical segmentation strategy in Dutch listeners.
• Determine if Dutch listeners rely on metrical cues or stress for word segmentation.

Main Methods:

• Three experiments using word-spotting tasks with Dutch monosyllabic words and disyllabic nonwords.
• Manipulation of stress and vowel quality to assess their impact on word identification.

Main Results:

• Stress significantly impacts Dutch listeners' ability and speed in spotting words.
• Vowel quality shows a small effect on error scores but not on response latencies.
• No evidence suggests Dutch listeners apply a metrical segmentation strategy.

Conclusions:

• Dutch listeners do not employ a metrical segmentation strategy for word identification.
• Speech segmentation strategies are influenced by language-specific phonological and lexical regularities.
• Stress, rather than metrical strength, appears to be a primary cue for Dutch word segmentation.
