摘要:

大多数客观的语音清晰度评估指标的计算需要干净的语音作为参考。这种要求可能会限制这些指标在现实世界场景中的适用性。为了克服这一限制,我们提出了一种基于深度学习的非侵入式语音可懂度评估模型,即STOI-Net。STOI-Net的输入和输出分别是语音频谱特征和预测的STOI分数。该模型是由一个卷积神经网络和双向长短期记忆(CNN-BLSTM)架构与乘法注意力机制的组合。实验结果表明,由STOI-Net估计的STOI分数与实际的STOI分数有很好的相关性时,测试与噪声和增强的语音话语。相关值分别为0.97和0.83,对于可见的测试条件(测试扬声器和噪声类型涉及训练集)和不可见的测试条件(测试扬声器和噪声类型不涉及训练集)。结果证实了STOI-Net在不参考干净语音的情况下准确预测STOI分数的能力。

英文摘要:

The calculation of most objective speech intelligibility assessment metrics requires clean speech as a reference. Such a requirement may limit the applicability of these metrics in real-world scenarios. To overcome this limitation, we propose a deep learning-based non-intrusive speech intelligibility assessment model, namely STOI-Net. The input and output of STOI-Net are speech spectral features and predicted STOI scores, respectively. The model is formed by the combination of a convolutional neural network and bidirectional long short-term memory (CNN-BLSTM) architecture with a multiplicative attention mechanism. Experimental results show that the STOI score estimated by STOI-Net has a good correlation with the actual STOI score when tested with noisy and enhanced speech utterances. The correlation values are 0.97 and 0.83, respectively, for the seen test condition (the test speakers and noise types are involved in the training set) and the unseen test condition (the test speakers and noise types are not involved in the training set). The results confirm the capability of STOI-Net to accurately predict the STOI scores without referring to clean speech.
