摘要:

知道房间的几何和声学参数可以有益于诸如音频增强现实、语音去混响或音频取证之类的应用。在本文中,我们研究的问题,联合估计的总表面积,体积,以及频率相关的混响时间和平均表面吸收的房间在一个盲目的方式,基于双通道嘈杂的语音记录从多个,未知的源接收器的位置。提出了一种新的利用单通道和通道间线索的卷积神经网络架构,并在一个大型的、逼真的模拟数据集上进行了训练。模拟和真实数据的结果表明,在一个房间中使用多个观测值显着减少了所有目标量的估计误差和方差,使用两个通道有助于估计表面和体积。该模型优于最近提出的盲体积估计方法所考虑的数据集。

英文摘要:

Knowing the geometrical and acoustical parameters of a room may benefit applications such as audio augmented reality, speech dereverberation or audio forensics. In this paper, we study the problem of jointly estimating the total surface area, the volume, as well as the frequency-dependent reverberation time and mean surface absorption of a room in a blind fashion, based on two-channel noisy speech recordings from multiple, unknown source-receiver positions. A novel convolutional neural network architecture leveraging both single- and inter-channel cues is proposed and trained on a large, realistic simulated dataset. Results on both simulated and real data show that using multiple observations in one room significantly reduces estimation errors and variances on all target quantities, and that using two channels helps the estimation of surface and volume. The proposed model outperforms a recently proposed blind volume estimation method on the considered datasets.
