Impression formation control device, method and program
According to an embodiment of the present invention, when impression formation for a listener with respect to a speaker is controlled, a speech voice signal of the speaker is acquired, a voice feature is extracted from the speech voice signal, a bias to an impression made on the listener by the speech voice signal is determined based on the extracted voice feature, a bias control signal for controlling the bias occurs based on a determination result of the bias and information indicating a preset control direction of the bias, and a stimulation control signal for giving external stimulation to the listener is generated in accordance with the bias control signal, and the generated stimulation control signal is output.
1 . An impression formation control device controlling impression formation for a listener with respect to a speaker, the impression formation control device comprising:
a first processing unit configured to acquire a speech voice signal of the speaker;
a second processing unit configured to extract a voice feature from the speech voice signal;
a third processing unit configured to determine a bias to an impression made on the listener by the speech voice signal based on the voice feature;
a fourth processing unit configured to generate a bias control signal for controlling the bias based on a determination result of the bias and information indicating a preset control direction of the bias; and
a fifth processing unit configured to generate a stimulation control signal for giving external stimulation to the listener in accordance with the bias control signal, and output the generated stimulation control signal.
2 . The impression formation control device according to claim 1 ,
wherein the second processing unit is configured to extract at least one of a fundamental frequency, a voice speed, and an intonation from the speech voice signal as a voice feature, and
wherein the third processing unit is configured to compare the extracted voice feature with a preset determination condition and determine the bias generated in the listener based on a comparison result.
3 . The impression formation control device according to claim 1 , wherein, when the external stimulation is a temperature, the fourth processing unit is configured to generate the bias control signal for designating a control direction and a control amount of the temperature based on the determination result of the bias and information indicating the preset control direction of the bias, and
wherein the fifth processing unit is configured to generate the stimulation control signal for giving the external stimulation to the listener by a change in the temperature in accordance with the bias control signal and output the generated stimulation control signal.
4 . The impression formation control device according to claim 1 , wherein, when the external stimulation is hardness, the fourth processing unit is configured to generate the bias control signal for designating a control direction and a control amount of the hardness based on a determination result of the bias and information indicating the preset control direction of the bias,
wherein the fifth processing unit is configured to generate the stimulation control signal for giving the external stimulation to the listener by the change in the hardness in accordance with the bias control signal and output the generated stimulation control signal.
5 . An impression formation control method of controlling impression formation for a listener with respect to a speaker, the impression formation control method being executed by an information processing device, the method comprising:
acquiring a speech voice signal of the speaker;
extracting a voice feature from the speech voice signal;
determining a bias to an impression made on the listener by the speech voice signal based on the voice feature;
generating a bias control signal for controlling the bias based on a determination result of the bias and information indicating a preset control direction of the bias; and
generating a stimulation control signal for giving external stimulation to the listener in accordance with the bias control signal, and outputting the generated stimulation control signal.
6 . A non-transitory computer readable medium storing a program, wherein execution of the program causes a computer to function as the impression formation control device according to claim 1 .
