车内通信音频规范 |
ITU-T P.1150建议书描述了车内通信(ICC)系统的通信要求,利用机动车辆车厢中集成的麦克风和扬声器放大对话,以改进机动车辆中所有乘员之间的通信。
本建议书规定了功能和质量的基本水平,以确保ICC的运作质量,使机动车驾驶员在与其他乘客交谈时,觉得没有必要通过转头提高自己的声音。这种方式的优点包括有助于防止司机分心。
为满足这些要求,本文定义了在机动车辆车厢内使用音频区进行音频区之间的语音通信,并为确保这些区之间有良好的语音清晰度和质量还定义了测试规范。本建议涵盖以下方面的要求和测试方法:
1)系统稳定性; 2)语音清晰度; 3)语音质量; 4)讲话人的定位精度。
驾驶员或乘客使用可佩戴耳机(音频电话)不属于本建议的讨论范围。 |
