Embodiment Construction
[0044] The present invention will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0045] Such as figure 1 Shown, the present invention comprises the following steps:
[0046] Step S1: By collecting the voice signals of each channel collected by the sound collection microphone and related sound pickup components, the digital signal and acoustic information of the sound source are respectively extracted; in practical applications, since the collection devices have been differentiated, each The speaker's real-time voice digital signal.
[0047] This step requires the following specific instructions:
[0048] First, the voice signal recorded by a single sound pickup device cannot actually provide sufficient information to tell whether there is crosstalk at the moment. , only different sound sources can be separated from the mixed voice recorded by the sound pickup device, but it is impossible to determine which s...
