    • A method for providing audible signals (such as speech) to a driver of a vehicle which appear to originate from a virtual sound source in front of the driver, so that it will feel normal for the driver to respond interactively by speaking without turning the head to the source of the audible signal. The driver's head position is estimated according to data provided by sensors in the driver's seat, and this position data, together with acoustical characteristics of the vehicle interior, is used to derive a transfer function for filtering electrical audible signals to the loudspeakers to simulate a virtual sound source in front of the driver.
    • 一种用于向车辆的驾驶员提供可听见的信号(例如语音)的方法,其似乎源于驾驶员前面的虚拟声源,使得驾驶员通过说话而不转动头来交互响应将感觉正常 到可听信号的来源。 驾驶员头部位置根据驾驶员座椅中的传感器提供的数据来估计,并且该位置数据以及车辆内部的声学特性被用于导出用于将扬声器的电声信号滤波到模拟虚拟 声源在司机面前。
