摘　　要：传统的日语学习者语音评价和正音训练存在效果不佳、效率低下等问题,尤其涉及特殊音拍和普通音拍的差异和区分这一音长控制难点。本研究面向应用于计算机辅助发音训练的客观评价模型构建,以日语促音的音长控制与产出为对象,利用统计分析明确母语者主观评价依据,探讨可客观评价学习者音长控制能力的客观指标。各类音长指标和主观评价间的相关性分析表明:相较于传统基于特殊音拍长度对发音进行评价的观点,元音起始点(Vowel onset)指标与主观评价值的相关系数最高(整体0.47,最高0.72),可以更好地反映评价者主观心理感知特征。回归分析表明:该指标对评价值的影响更显著,纳入模型后可提高客观评价精度。该结果提示教学中应重视学生对单词整体节奏的把握,而非仅着眼于局部音长。Evaluation and correction of L2 learners’speech are confronted with problems like inaccuracy and inefficiency.To provide an automatic objective evaluation of naturalness in timing control for Computer-Aided Pronunciation Training(CAPT),Japanese L2 timing characteristics were analyzed to correlate with the corresponding subjective evaluation scores given by native speakers.An objective measurement based on the vowel onset as a key perceptual and psycho-acoustic marker was proposed to estimate a subjective evaluation of L2 speakers’production.The experimental results showed that the vowel onset measurement had a significantly higher correlation(r=0.48,p<0.001 across all words;r=0.72 as maximum,p<0.001 in the specific word)with the subjective evaluation score,which was more stable than other measurements solely focusing on the local phonemic length differences.The linear regression analysis showed that the vowel onset measurement affected the evaluation more than the others(standardized coefficient=0.61,p<0.001 across all words).These results suggest that applying the parameters that can reflect the native evaluators’psycho-perceptual characteristics would be more effective for building up an objective evaluation of L2 timing control.New insights of paying more attention to the learners’proficiency of the overall rhythm of the word than the local length were assumed as well.
