Speech Perception and Production Training Data for Japanese Learners of English

A research document details a study on articulatory target-based training for second language acquisition. The study involved seven Japanese male speakers performing perceptual tests before and after training on American English vowels. The document was authored by Atsuo Suemitsu and last updated in April 2026.

Use Cases

• Analyzing the effect of articulatory feedback on speech perception based on the described ABX perceptual test results.
• Studying individual variability in response to motor-based pronunciation training as mentioned in the description.
• Investigating the relationship between production and perception improvement for non-native vowel sounds like /æ/.
• Evaluating training methods for second language learners based on the described electromagnetic articulography approach.

Strengths

• The study design and results are described in detail, including the number of participants (seven).
• The document is licensed under CC-BY-4.0, allowing for reuse and redistribution.
• The last update date is explicitly provided (2026-04-13).

Limitations

• The dataset is a 690.5 KB DOCX file, which is a small text document, not a structured data file.
• Row count and column-level documentation are absent; data must be extracted from the prose.
• The sample size of seven participants is small, which may limit generalizability.
