摘　　要：从语音与话带数据的特点出发，结合现有的研究成果和自己的实验数据，讨论了几种语言与话带数据的鉴别方法。所使用的参数是：信号的短时幅度与能量、一阶和二阶过零率、自相关函数及基音周期等。Based on the characteristics of speech and voiceband data,as well as available research fruit and authors' research practice, several speech/voiceband data discriminationmethods are proposed. The involved parameters are short-time amplitude and energy,lst-and2nd-order zero-crossing rate,autocorrelation function and pitch period.
