The Frame Constraint on Experimentally Elicited Speech Errors in Japanese

Area of Science:

• Psycholinguistics
• Phonetics
• Speech Production

Background:

• The syllable position effect in speech errors suggests language frames constrain sound ordering.
• Evidence primarily comes from Indo-European languages and naturally occurring errors.
• Limited research exists on experimentally elicited errors and non-Indo-European languages.

Purpose of the Study:

• To investigate the syllable position effect in experimentally elicited Japanese sound errors.
• To determine if the mora, a basic sound unit in Japanese, exhibits this effect.
• To contribute to understanding cross-linguistic constraints on speech production.

Main Methods:

• Experimentally elicited sound errors in Japanese participants.
• Analysis of error patterns focusing on the position of sounds within morae.
• Comparison of results with existing theories on the syllable position effect.

Main Results:

• The syllable position effect was observed in Japanese mora errors.
• Sound errors demonstrated a tendency for sounds in similar mora positions to be swapped.
• Findings align with the hypothesis of frame-based constraints on sound sequencing.

Conclusions:

• The syllable position effect is not limited to Indo-European languages.
• Japanese mora errors provide evidence for universal or widespread frame constraints in speech production.
• This study enhances our understanding of the interplay between linguistic content and structural frames in spoken language.
