Abrégé

The present disclosure provides a method for detecting voice using an in-ear audio sensor, including performing the following processing on each frame of input signals collected by the in-ear audio sensor: calculating a count change value based on at least one feature of an input signal of a current frame, wherein the at least one feature includes at least one of an estimated signal-to-noise ratio, a spectral centroid, a spectral flux, a spectral flux difference value, spectral flatness, energy distribution, and spectral correlations between adjacent frames; adding the calculated count change value with a previous count value of a previous frame to obtain a current count value; comparing the obtained current count value with a count threshold; and determining the category of the input signal of the current frame based on the comparison result and feature attributes, wherein the category includes noise, voiced sound, or unvoiced sound.

Abrégé

Methods and systems are proposed for a communication network. In one example, a system for a vehicle comprises a controller of the vehicle comprising instructions stored in memory thereof that when executed enable the controller to gather data related to a vehicle event at a location and store the data in memory in response to the location being free of a road-side unit (RSU), where the controller is further configured to establish a vehicle-to-infrastructure network in wireless communication with the vehicle at a second location different from the location.

Abrégé

A vocal removal method and a system thereof are provided. In the vocal removal method, a voice separation model is generated and trained to process a real-time input music to separate the voice and the accompaniment. The vocal removal method further comprises the steps of feature extraction and reconstruction to obtain the voice minimized music.
