摘要:

降噪是现代助听器的重要组成部分,并且包括在大多数市售设备中。然而,基于深度学习的最先进算法要么不考虑实时和频率分辨率约束,要么在非常嘈杂的条件下导致质量差。为了改善噪声环境下的单声道语音增强,我们提出了CLCNet,一个基于复值线性编码的框架。首先,我们定义了复线性编码(CLC)的线性预测编码(LPC),这是应用在复频域的动机。其次,我们提出了一个框架,结合复杂的频谱图输入和系数输出。第三,我们定义了一个参数归一化复值频谱图,符合低延迟和在线处理。我们的CLCNet进行了评估的混合EUROM数据库和现实世界的噪声数据集记录与助听器,并与传统的实值维纳滤波器增益。

英文摘要:

Noise reduction is an important part of modern hearing aids and is included in most commercially available devices. Deep learning-based state-of-the-art algorithms, however, either do not consider real-time and frequency resolution constrains or result in poor quality under very noisy conditions. To improve monaural speech enhancement in noisy environments, we propose CLCNet, a framework based on complex valued linear coding. First, we define complex linear coding (CLC) motivated by linear predictive coding (LPC) that is applied in the complex frequency domain. Second, we propose a framework that incorporates complex spectrogram input and coefficient output. Third, we define a parametric normalization for complex valued spectrograms that complies with low-latency and on-line processing. Our CLCNet was evaluated on a mixture of the EUROM database and a real-world noise dataset recorded with hearing aids and compared to traditional real-valued Wiener-Filter gains.
