摘要： A speech signal isolation system configured to isolate and reconstruct a speech signal transmitted in an environment in which frequency components of the speech signal are masked by background noise. The speech signal isolation system obtains a noisy speech signal from an audio source. The noisy speech signal may then be fed through a neural network that has been trained to isolate and reconstruct a clean speech signal from against background noise. Once the noisy speech signal has been fed through the neural network, the speech signal isolation system generates an estimated speech signal with substantially reduced noise.
摘要翻译： 一种语音信号隔离系统，被配置为隔离和重构在其中语音信号的频率分量被背景噪声屏蔽的环境中发送的语音信号。 语音信号隔离系统从音频源获得有噪声的语音信号。 然后可以通过经过训练的神经网络馈送噪声语音信号，以隔离和重建来自背景噪声的干净的语音信号。 一旦噪声语音信号已通过神经网络馈送，则语音信号隔离系统产生具有显着降低的噪声的估计语音信号。
