The invention discloses a cabin navigation voice prompt multimedia volume control method and system, and belongs to the technical field of automobile volume adjustment, and the method comprises the steps: S1, vehicle setting judgment; s2, detecting the vehicle speed, judging the current vehicle state, and calling a volume compensation factor according to the vehicle state; s3, detecting a navigation voice prompt volume level, and calling a volume suppression factor according to different volume level states; s4, detecting decibel difference values between the navigation voice prompt volume and the multimedia playing volume, and calling an inhibition factor according to different volume difference values; s5, after calling the multimedia volume level through various compensation factors and inhibition factors, outputting the multimedia volume level; s6, setting a sampling period as T, and keeping the output volume unchanged in the sampling period; and S7, after the sampling period T is exceeded, performing state detection and output volume adjustment of the next sampling period on the real-time state. According to the method, information such as different vehicle conditions, multimedia audio playing states, navigation voice prompt setting states and the like is identified to realize dynamic adjustment of voice prompt of a cabin pre-installed navigation application on multimedia volume suppression, so that optimal function experience and sound perception effect of multimedia and navigation are realized under different working conditions of a vehicle; interference among different sound sources in the driving process is avoided, and the sound sense experience of a user is improved.
本发明公开了一种座舱导航语音提示多媒体音量控制方法及系统,属于汽车音量调节技术领域,包括:S1、车辆设置判断;S2、检测车辆车速,判断当前车辆状态,并根据车辆状态调用音量补偿因子;S3、检测导航语音提示音量等级,根据不同音量等级状态调用音量抑制因子;S4、检测导航语音提示音量与多媒体播放音量的分贝差值,根据不同音量差值调用抑制因子;S5、多媒体音量等级经过各类补偿因子及抑制因子调用后,进行输出;S6、采样周期设定为T,在采样周期内,输出音量保持不变;S7、超过采样周期T后,对实时状态进行下一个采样周期的状态检测及输出音量调节。该方法通过识别不同车况、多媒体音频播放状态、导航语音提示设置状态等信息来实现座舱预装导航应用的语音提示对多媒体音量抑制的动态调节,实现车辆在不同的工况条件下,多媒体及导航最优的功能体验及声觉感知效果,避免驾驶过程中不同音源间的干扰,改善了用户的声觉体验。
