<p>A method for determining the type of non-noise audio signal is disclosed, said method comprises: acquiring feature parameters of non-noise audio signal; determining initially the type of non-noise audio signal with decision tree according to said feature parameters; determining the type of said non-noise audio signal according to linguistic environment of said non-noise audio signal and initial determination result. Furthermore an apparatus for determining the type of non-noise audio signal is disclosed, with the method and apparatus, the type of non-noise audio signal is determined according to its feature parameters which is independent onencoder algorithm, and independency and portability of the algorithm is enhanced.</p> |
