Abstract
A signal processing device (10) includes: a speech enhancement unit (11) that generates, from an observation signal, an enhancement signal in which a voice of a speaker is enhanced; an original sound addition unit (12) that adds the observation signal to the enhancement signal; and a speech recognition unit (13) that performs speech recognition on the enhancement signal to which the observation signal is added by the original sound addition unit (12).
Claims18
A signal processing device comprising:
- a speech enhancement unit that generates, from an observation signal, an enhancement signal in which a voice of a speaker is enhanced;
- an addition unit that adds the observation signal to the enhancement signal;
- and
- a speech recognition unit that performs speech recognition on the enhancement signal to which the observation signal is added by the addition unit.
A signal processing method executed by a signal processing device, the signal processing method comprising:
- a process of generating, from an observation signal, an enhancement signal in which a voice of a speaker is enhanced;
- a process of adding the observation signal to the enhancement signal;
- and
- a process of performing speech recognition on the enhancement signal to which the observation signal is added in the adding process.
A signal processing program for causing a computer to execute:
- generating, from an observation signal, an enhancement signal in which a voice of a speaker is enhanced;
- adding the observation signal to the enhancement signal;
- and
- performing speech recognition on the enhancement signal to which the observation signal is added in the adding step.
