H1: intelligibility, H2: comprehensibility, H3: accentedness, H4: bias towards L2 accents, H5: individual sounds, each with overall and language-specific predictions.本数据集涵盖五项评估维度：H1为可懂度（intelligibility），H2为可理解度（comprehensibility），H3为口音浓重度（accentedness），H4为针对第二语言（L2）口音的偏好偏差，H5为单个音素，所有维度均支持生成整体预测与特定语言预测。
