Mandarin Speakers' English Phonetic Training Scores Across Six Contrasts

Li, Ying's dataset contains individual participant accuracy scores from a 16-week classroom-based audiovisual high-variability phonetic training study. It includes perception and production accuracy for six English sound contrasts, measured at pre-test, immediate post-test, and two-month delayed post-test intervals. The data was published via Harvard Dataverse in April 2026.

Use Cases

• Evaluate the efficacy of audiovisual phonetic training based on pre/post-test accuracy scores.
• Analyze the role of articulatory visual salience in learning based on the described training method.
• Compare perception and production gains for different English sound contrasts based on the six listed pairs.
• Study the retention of phonetic training effects based on the two-month delayed post-test scores.

Strengths

• Data covers a 16-week longitudinal study with three distinct measurement time points.
• Includes both perception and production accuracy scores for six specific English sound contrasts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
