摘要
本文在讨论声音感知特征的基础上,提出了一个作为语音信号预处理系统的语音响度感知模型,由此得到的响度谱可用于语音识别。
In this paper, the psychoacustic fundamentals which are active in human speech perception are discussed and a model of loudness sensation that can be favourably used as a speech signal preprocessing system is presented, the loudness spectrum is obtained from the model and can be used for speech recognition.
