AI Technical Summary

Technical Problem

In the prior art, the experience of using karaoke without microphone in the car is poor. The on-board microphone is easy to pick up sounds other than the singer in a noisy environment, resulting in problems such as howling and noise.

Method used

By acquiring the initial audio signal collected by the audio acquisition device, the first song audio signal and the vocal feedback signal are eliminated, and a clean second vocal signal is obtained. The method includes performing vocal accompaniment separation processing on the original song audio based on the vocal accompaniment separation model, and eliminating the song audio signal and the vocal feedback signal in the initial audio signal.

Benefits of technology

Effectively eliminate echoes in the car, ensure a clean second vocal signal, avoid whistling, noise and other problems, and improve the karaoke experience without kilograms in the car.

Abstract

The invention provides an in-vehicle microphone-free karaoke method and device, a vehicle, electronic equipment and a storage medium, and relates to the technical field of audio processing. The method comprises the following steps: acquiring an initial audio signal acquired by an audio acquisition device; eliminating a first song audio signal in the initial audio signal to obtain a first audio signal; the first song audio signal is a feedback signal obtained by outputting a song audio signal output by an audio output device from the audio output device and transmitting the song audio signal to the audio acquisition device; based on a first human voice signal output by an audio output device, eliminating a human voice feedback signal in the first audio signal to obtain a second audio signal; the human voice feedback signal is a feedback signal obtained by outputting the first human voice signal from an audio output device and transmitting the first human voice signal to the audio acquisition device; and determining a second human voice signal to be output based on the second audio signal. The problems of howling, noise and the like can be avoided, and the karaoke experience of microphone-free karaoke in the vehicle is improved.
