Problems solved by technology

If you want to get good low-frequency performance, you will need very thick sound-absorbing / sound-insulating materials. In other words, passive noise reduction has high requirements for the internal space of the product, and is not suitable for products with small size or requirements for appearance design.

Abstract

The invention discloses a device voice noise reduction method, an electronic device and a storage medium, and the device voice noise reduction method is characterized in that at least one noise microphone is arranged near a noise source in the device, and a voice microphone is arranged outside the device. The method comprises the following steps: performing echo cancellation on an initial voice signal based on a noise signal collected by a noise microphone and the initial voice signal collected by a voice microphone to obtain an echo cancellation voice signal; and inputting the echo cancellation voice signal into a pre-trained neural network model to suppress the equipment noise in the echo cancellation voice signal. And finally, clean user voice is obtained, and the voice intelligibility is greatly improved, so that effective real-time communication between users is established.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a device voice noise reduction method, an electronic device and a storage medium. Background technique [0002] At present, with the rapid development of the medical industry, some advanced medical equipment, such as nuclear magnetic resonance (MR, Magnetic Resonance) and electronic computer tomography (CT, Computed Tomography) and other advanced medical equipment, have solved more medical problems. However, during MR and CT scans, the subject and the doctor are in two separate rooms. When the machine is turned on, the high-intensity noise is generated, making it impossible for the doctor and the subject to communicate. [0003] At present, the existing products on the market mainly adopt active noise reduction and passive noise reduction. Active noise reduction is to collect the target noise (equipment spontaneous noise, environmental noise, etc.) through ...
