Problems solved by technology

[0004] However, based on timing features and short-term frequency features, it is impossible to effectively identify the noise with large frequency differences and the useful speech signal in the speech data, and then the noise with large frequency differences cannot be filtered from the useful speech signal, resulting in the speech enhancement of the speech signal. less effective

Abstract

The embodiment of the invention provides a speech enhancement model, electronic equipment, a storage medium and a related method. The speech enhancement method comprises the following steps: converting noisy speech data into time-frequency domain feature data; generating a masking value of the noisy voice data according to the long-range correlation of the time-frequency domain characteristic data in the frequency direction; and generating enhanced voice data of the noisy voice data according to the masking value and the time-frequency domain feature data. According to the scheme, the effect of performing voice enhancement on the voice signal can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of speech processing, and in particular, to a speech enhancement model, electronic equipment, storage media and related methods. Background technique [0002] Speech enhancement is a speech processing technology that extracts useful speech signals from the noise background to suppress and reduce noise interference after the speech signal is interfered or annihilated by various noises. Speech enhancement is widely used in real-time communication (RTC) audio and video conferencing, courier classrooms and other scenarios. [0003] At present, when performing speech enhancement on speech data, the timing features of the speech data along the time direction and the short-term frequency features along the frequency direction are extracted, and Jier performs speech enhancement on the speech data according to the timing features and short-term frequency features to suppress the speech dat...
