Abstract
Deterioration of voice extraction performance when positions of a plurality of microphones are changed is prevented. A signal processing device according to an embodiment of the present technology includes a voice extraction unit that performs voice extraction from signals of a plurality of microphones, in which the voice extraction unit uses, when respective positions of the plurality of microphones are changed to positions where other microphones have been present, respective signals of the plurality of microphones as signals of the other microphones. Thus, it is possible to cancel the effect of changing the positions of respective microphones on the voice extraction.
Claims11
A signal processing device comprising a voice extraction unit that performs voice extraction from signals of a plurality of microphones, wherein
- the voice extraction unit uses, when respective positions of the plurality of microphones are changed to positions where other microphones have been present, respective signals of the plurality of microphones as signals of the other microphones.
A signal processing method comprising
- a voice extraction step of performing voice extraction from signals of a plurality of microphones, wherein
- in the voice extraction step, when respective positions of the plurality of microphones are changed to positions where other microphones have been present, respective signals of the plurality of microphones are used as signals of the other microphones.
A program executed by an information processing device that performs voice extraction from signals of a plurality of microphones,
- the program causing the information processing device to implement a function of, when respective positions of the plurality of microphones are changed to positions where other microphones have been present, using respective signals of the plurality of microphones as signals of the other microphones.
