基于PESQ的空乘人员语音质量评价系统设计与实现

Design and Implementation of Air Stewardess Speech Quality Evaluation System Based on PESQ

设计并开发了一套基于PESQ的空乘人员语音质量评价系统。详细介绍了ITU-T推荐的P.862建议的PESQ算法,并将其与声压级、1/3倍频程一起构成了一种新的语音质量的客观评价标准,设计并实现了系统的软硬件。该系统作为飞机综合训练舱服务训练系统的一个子系统,为空乘人员的模拟训练提供了有力的工具,具有较高的应用价值。

An stewardess speech quality evaluation system is designed and implemented based on PESQ. The PESQ arithmetic which is proposed by ITU-T P. 862 recommendation is introduced. The PESQ arithmetic, voice press level and one-third octave bands spectrum make a new speech quality evaluation standard, according which software and hardware are designed and implemented. To be a subsystem of airplane serving and training system, it provides a powerful tool for air stewardess simulate training and it has a high application value.
