Abstract

The present invention disclosed a voice enhancement system based on low -cost wearable sensors.The system includes wearable devices and intelligent devices, which include wearable devices include micro -control unit, audio processing unit, filter, in -ear headset and piezoelectric ceramics.Under the control, the sound signals and cervical vibration signals in the ear canal are collected when the user speaks, and it is transmitted to the smart terminal.Time -frequency diagram or time sequence, input to the deep learning model of pre -training, and obtain the target quality voice signal. The resolution of the target quality voice signal and the user's hearing sense is better than the signal of the wearable device collection.The present invention can convert low -cost wearable sensor signals into high -quality signals in the case of protecting user privacy and suitable for daily use.

Description

technical field [0001] The present invention relates to the technical field of wearable devices, and more particularly, to a speech enhancement system based on low-cost wearable sensors. Background technique [0002] As one of the most important functions of the device, human-computer interaction is limited by the design of the wearable device, which affects the user experience. In the interaction of wearable devices, voice interaction is a more natural and low-cost way to learn. Among wearable devices, smart earphones occupy most of the market share, and similar neck-mounted devices (smart necklaces, neck-mounted headphones) are also an emerging wearable device that may be accepted by users. For wearable devices, they only need to be equipped with a microphone to complete the voice input interaction. However, due to the characteristics of the microphone itself, it is more sensitive to external environmental noise, which will also result in the recorded data containing mor...
