The invention discloses a vehicle-mounted KTV control method and device and a vehicle-mounted intelligent network connection terminal, and the method comprises the steps: carrying out the human voice suppression processing of an initial audio signal, and obtaining a first audio signal, wherein the human voice suppression comprises human voice elimination and human voice weakening, and the initial audio signal is a multimedia audio signal; picking up an in-vehicle environment audio signal and carrying out echo cancellation and human voice positioning processing to obtain at least one initial human voice signal, wherein the environment audio signal comprises a first audio signal, a human voice signal and a noise signal; and performing sound modulation on the first audio signal and the initial human voice signal to obtain a target audio signal. Existing software and hardware resources, such as a microphone, a multimedia player, a DSP audio processor and a loudspeaker, of the vehicle-mounted intelligent network connection terminal are utilized, an additional K-singing microphone system or a mobile terminal does not need to be utilized, the function of high-quality karaoke in the vehicle can be achieved, the function of simultaneous karaoke of multiple persons in the vehicle can also be achieved, and the vehicle using experience is greatly improved.

    本发明公开了一种车载KTV控制方法及装置、以及车载智能网联终端,所述方法包括:对初始音频信号进行人声抑制处理,得到第一音频信号;其中,人声抑制包括人声消除和人声弱化,初始音频信号为多媒体音频信号;拾取车内环境音频信号并进行回声消除和人声定位处理,得到至少一个初始人声信号;其中,环境音频信号包括第一音频信号、人声信号和噪音信号;对第一音频信号和初始人声信号进行声音调制,得到目标音频信号。本发明利用车载智能网联终端的现有软硬件资源,例如麦克风、多媒体播放器、DSP音频处理器和喇叭等,而无需利用外加的唱K麦克风系统或移动终端,不仅能实现在车内优质K歌的功能,还能实现车内多人同时K歌的功能,极大提高用车体验。
