Silent communication method, silent communication system and storage medium

Abstract

The invention discloses a silent communication method, a silent communication system and a storage medium, which are used for meeting information communication requirements in some specific scenes. The silent communication method comprises the steps of respectively collecting a first IMU signal, a first EMG signal and a first voice signal during the speaking process of a first user; determining the first form position change information of the joint muscle according to the first IMU signal; determining the first myoelectricity change information according to the first EMG signal; extracting first acoustic representation feature information from the first voice signal; training based on the first form position change information, the first myoelectricity change information and the first acoustic representation feature information to obtain a voice prediction model; and recognizing voice information expressed by the second user in a voice expression process of the second user by utilizing the voice prediction model.

Description

technical field [0001] The present invention relates to the technical field of voice signal processing, in particular to a silent communication method, system and storage medium. Background technique [0002] In some specific scenarios, such as in a noisy environment, because the surrounding environment is too noisy, the sound will be affected, resulting in the inconvenience of voice communication, and even affect the transmission of information; and in some environments that require extremely quiet Communication will affect other people. [0003] At present, there are already some high-precision electronic larynxes. In the medical field, there are also many electronic devices that assist people with vocal impairment. The vibration signal when speaking achieves the purpose of reconstructing the voice signal. However, these devices have the following problems. First, it is inconvenient to use the breath to operate. It relies on the hose put into the throat to work, which is...

Problems solved by technology

However, these devices have the following problems. First, it is inconvenient to use the breath to operate. It relies on the hose put into the throat to work, which is very unfriendly to the human body. Second, the electronic throat is converted into an analog signal through a vibration signal and then uses a digital signal for audio. For signal conversion, you need to press the sensor with your hand to make it close to your throat, and in some cases there will be problems such as distortion
