摘要:

主观测试是评估语音质量和可懂度的金标准;然而,它们耗时且昂贵。因此,与人类感知相一致的客观度量至关重要。本研究使用中文语音数据集评估常用客观度量与主观语音质量和可懂度之间的相关性。此外,提出了新的客观度量,利用深度学习技术结合现有客观度量来预测主观质量和可懂度。所提出的深度学习模型在不显著影响预测性能的情况下减少了训练数据量。我们分析了深度学习模型,以理解客观度量如何反映主观质量和可懂度。我们还探讨了将主观语音质量评分纳入语音可懂度预测的影响。我们的发现为客观度量与人类感知之间的关系提供了有价值的见解。

英文摘要:

Subjective tests are the gold standard for evaluating speech quality and intelligibility; however, they are time-consuming and expensive. Thus, objective measures that align with human perceptions are crucial. This study evaluates the correlation between commonly used objective measures and subjective speech quality and intelligibility using a Chinese speech dataset. Moreover, new objective measures are proposed that combine current objective measures using deep learning techniques to predict subjective quality and intelligibility. The proposed deep learning model reduces the amount of training data without significantly affecting prediction performance. We analyzed the deep learning model to understand how objective measures reflect subjective quality and intelligibility. We also explored the impact of including subjective speech quality ratings on speech intelligibility prediction. Our findings offer valuable insights into the relationship between objective measures and human perceptions.
