【摘要】 将线性预测倒谱系数LPCC作为语音特征相似度的评价参数,采用欧氏距离来衡量语音的相似度,据此分析测试者语音与标准语音(或参考语音)间的偏差,以此给出测试者语音质量优劣的评价结果。该评价方法有助于语言学习者提高发音质量和朗读能力,并为语言口语教学评价提供一种新思路和新方法。更多还原

【Abstract】 Using Euclidean distance to measure phonological similarity, based on LPCC of linear prediction cepstrum coefficient as evaluation parameters of speech feature similarity, we analyse the deviation between speech and standard speech(or reference speech) by testers to be given the evaluation results of the voice quality. This evaluation method is helpful to improve the quality of pronunciation and reading ability, and it also provides a new way for the evaluation in language teaching.更多还原
