Abstract
A signal processing device includes: an input unit to which a microphone signal including a mixed sound in which a target sound and a sound other than the target sound are mixed and a one-dimensional time-series signal acquired by an auxiliary sensor and synchronized with the target sound are input; and a sound source extraction unit that extracts a target sound signal corresponding to the target sound from the microphone signal on the basis of the one-dimensional time-series signal.
Claims19
A signal processing device comprising:
- an input unit to which a microphone signal including a mixed sound in which a target sound and a sound other than the target sound are mixed and a one-dimensional time-series signal acquired by an auxiliary sensor and synchronized with the target sound are input;
- and
- a sound source extraction unit that extracts a target sound signal corresponding to the target sound from the microphone signal on a basis of the one-dimensional time-series signal.
A signal processing method comprising:
- inputting a microphone signal including a mixed sound in which a target sound and a sound other than the target sound are mixed and a one-dimensional time-series signal acquired by an auxiliary sensor and synchronized with the target sound to an input unit;
- and
- extracting a target sound signal corresponding to the target sound from the microphone signal on a basis of the one-dimensional time-series signal by a sound source extraction unit.
A program for causing a computer to execute a signal processing method comprising:
- inputting a microphone signal including a mixed sound in which a target sound and a sound other than the target sound are mixed and a one-dimensional time-series signal acquired by an auxiliary sensor and synchronized with the target sound to an input unit;
- and
- extracting a target sound signal corresponding to the target sound from the microphone signal on a basis of the one-dimensional time-series signal by a sound source extraction unit.
