| 摘 要： | 获取复杂声学背景下的语音流以得到有用信息是一些部门极其重要的工作.研究了在无线话带通信中实现语音流的机器自动检出.结合人的听觉外周和听觉心理的研究,提出了一种基于人耳听觉感知特性的噪声环境下语音流检测方法.该实验采用来自现场的大量的无线话带录音作为测试数据,结果表明,这种新的方法可很好地排除各种噪声的干扰,强噪声环境下表现良好.无论在抗噪方法还是在实际应用中,都有很好的应用前景.

| Abstract: | Taking speech stream from a complicated acoustic environment has many important uses.An automatically extracting method by machine from wireless speech band communication is employed.Combining auditory model and psychoacoustics, a new method for speech detection was proposed based on the human auditory perception properties.Using many wireless speech band records on the spot,the results show that all kinds of noise,especially impulse noise,can be removed effectively. The new method in speech stream detection in adverse environments performed well,and its application prospect is promising not only in denosing but also in practice. |
