一种确定非噪声音频信号类别的方法及装置
摘要：
本发明公开了一种确定非噪声音频信号类别的方法，首先，获取非噪声音频信号的特征参数；然后，根据所述特征参数，利用决策树初步判决所述非噪声音频信号的类别；最后，根据所述非噪声音频信号的语境和所述初步判决的结果，确定所述非噪声音频信号的类别。本发明还公开了一种确定非噪声音频信号类别的装置。本发明通过不依赖于编码器算法的非噪声音频信号的特征参数，对所述非噪声音频信号的类别进行判定，增强了算法的独立性和可移植性。
摘要（英）：

The invention discloses a method for determining categories of non-noise audio signals. Firstly, characteristic parameters of the non-noise audio signals are obtained. Then, the categories of the non-noise audio signals are judged primarily by a decision tree according to the characteristic parameters. At last, the categories of the non-noise audio signals are determined according to contexts of the non-noise audio signals and the result of the primary judgment. A device for determining the categories of the non-noise audio signals is also disclosed. The categories of the non-noise audio signals are judged by the characteristic parameters of the non-noise audio signals which do not depend on encoder algorithm. And the independence and the portability of the algorithm are enhanced.
