车载麦克风布置研究

Research on the Layout of Microphones in Vehicles

麦克风在车内应用广泛,不同车辆的麦克风数量也各不相同。麦克风布置的合理性直接影响语音识别率,是语音控制功能得以实现的重要硬件基础。文章首先分析麦克风单体在整车布置中需要关注的要素,然后逐个分析不同数量语音麦克风在整车中的布置方式,最后分析其他类型麦克风在整车中的布置方式。

The microphones are widely used in car applications,and the number of micro⁃phones varies among different vehicles.The rationality of microphone layout directly affects the speech recognition rate and is an important hardware foundation for the implementation of voice con⁃trol functions.Firstly,the elements that need to be considered in the overall arrangement of indi⁃vidual microphones in the vehicle are analyzed.Then,the layouts of different quantities of speech mi⁃crophones in the vehicle are analyzed one by one.Finally,the arrangements of other types of micro⁃phones in the vehicle are analyzed.
