J-AESOP Rating Data (6_01 & 6_02)

This dataset contains the perceptual rating data for English (Task 6_01) and Japanese (Task 6_02) speech from the J-AESOP corpus (Yazawa et al., 2025). Rating 6_01.csv includes 10-point ratings of all speakers' English speech for segmental accuracy, prosody, fluency, and nativelikeness. The raters consisted of native listeners of American English (n = 4), Japanese (n = 4), other Asian languages (n = 4), and European languages (n = 4). These ratings were originally collected as part of Konishi (2022). Rating 6_02.csv includes 100-point ratings of all speakers’ Japanese speech for foreign-accentedness and comprehensibility. All raters were native listeners of Japanese (n = 26). Of these, 10 raters were recruited for Yazawa et al. (2023), and an additional 16 were recruited for Yazawa et al. (2024).
