Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] A method for identifying the source of mobile phones in an additive noise environment based on fusion features proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:
[0038] Step 1: Select M mobile phones of different mainstream brands and models; then use each mobile phone to obtain P speech samples corresponding to N individuals, and each mobile phone corresponds to a total of N×P speech samples; All speech samples constitute a subset, and a total of M × N × P speech samples of M subsets constitute a basic speech library; wherein, M≥10, M=24 in this embodiment, N≥10, in this embodiment Take N=12, P≧10, and take P=50 in this embodiment.
[0039] In this embodiment, in step 1, there are two ways to use each mobile phone to obtain P voice samples corre...
