Abstract

The invention relates to a pickup and noise reduction method and device and a server. The pickup and noise reduction method comprises the steps that a pickup and noise reduction model is established;awakening voice is monitored in real time; and the wake-up voice is input into the pickup noise reduction model, and a pure control instruction is input to drive an electric appliance through the purecontrol instruction. According to the invention, noise reduction optimization can be carried out on pickup according to the characteristic curves of bottom noise and wind noise of various electric appliance models, the wake-up rate is improved, wrong wake-up is avoided, and the user experience is improved.

Description

technical field [0001] The present application belongs to the technical field of speech processing, and in particular relates to a sound pickup and noise reduction method, device and server. Background technique [0002] With the rapid development of Internet of Things technology, people use smart home products more and more frequently, and it is more and more common to use the voice wake-up function on smart home products. However, the currently used voice wake-up technology is difficult to successfully wake up the device in a noisy environment, or false wake-up occurs, resulting in poor wake-up effect and affecting user experience and other bottleneck problems. Contents of the invention [0003] In order to overcome at least to a certain extent the problem that the currently used voice wake-up technology is difficult to successfully wake up the device in a noisy environment, or causes false wake-up, resulting in poor wake-up effect and affecting user experience, this app...
