摘要翻译：
在这项研究中，我们提出了一个深度神经网络，用于从无声的唇动视频中重建可理解的语音。我们采用听觉谱图作为语音的频谱表示，并采用相应的语音生成方法，得到了一种更自然的语音重建。我们提出的网络包括一个自动编码器，从听觉频谱图中提取瓶颈特征，然后将其作为目标用于我们的主唇读网络，该网络由CNN、LSTM和全连接层组成。实验结果表明，该自动编码器能够重建出98%的原始听觉声谱图，并提高了主唇读网络重建语音的质量。我们的模型在不同说话人上联合训练，能够提取单个说话人的特征，并给出了有希望的重建可理解语音的结果，具有较高的词识别精度。

英文摘要：
  In this study, we propose a deep neural network for reconstructing intelligible speech from silent lip movement videos. We use auditory spectrogram as spectral representation of speech and its corresponding sound generation method resulting in a more natural sounding reconstructed speech. Our proposed network consists of an autoencoder to extract bottleneck features from the auditory spectrogram which is then used as target to our main lip reading network comprising of CNN, LSTM and fully connected layers. Our experiments show that the autoencoder is able to reconstruct the original auditory spectrogram with a 98% correlation and also improves the quality of reconstructed speech from the main lip reading network. Our model, trained jointly on different speakers is able to extract individual speaker characteristics and gives promising results of reconstructing intelligible speech with superior word recognition accuracy.
