Patent ID: 7120576

Claim:
A method for detecting music in a speech signal having a plurality of frames, said method comprising: defining a music threshold value for a first parameter extracted from a frame of said speech signal; defining a background noise threshold value for said first parameter; defining an unsure threshold value for said first parameter, wherein said unsure threshold value falls between said music threshold value and said background noise threshold value; wherein if said first parameter does not fall between said music threshold value and said background noise threshold value, classifying said speech signal as music if said first parameter is in closer range of said music threshold value than said unsure threshold value; and classifying said speech signal as background noise if said first parameter is in closer range of said background noise threshold value than said unsure threshold value; wherein if said first parameter falls between said music threshold value and said background noise threshold value, classifying said speech signal as music or background noise based on analyzing a plurality of first parameters extracted from said plurality of frames.
