Abstract
A method of generating a sympathetic back-channel signal is provided. The method includes receiving a voice signal from a user, determining whether predetermined timing is timing at which a back-channel signal is output in response to the input of the voice signal at the predetermined timing, storing the voice signal that has been input so far if the predetermined timing is the timing at which the back-channel signal is output as a result of the determination, determining back-channel signal information based on the stored voice signal, and outputting the determined back-channel signal information.
Claims11
A system for method of generating a sympathetic back-channel signal, comprising:
- a microphone;
- memory;
- an output unit;
- and
- a processor configured to:
- receive a voice signal from a user through the microphone;
- determine whether the voice signal has a length corresponding to a predetermined first timing threshold;
- determine whether a bundle interval having a length corresponding to a predetermined second timing threshold is input after receiving the voice signal that has the length corresponding to the first timing threshold;
- determine an output timing for outputting back-channel signal information as a timing at which the bundle interval is input;
- store, in the memory, the voice signal input up to the output timing;
- determine the back-channel signal information based on the stored voice signal;
- and
- output the determined back-channel signal information through the output unit.
A system for generating a sympathetic back-channel signal, comprising:
- a microphone;
- memory;
- an output unit;
- and
- a processor configured to:
- receive a voice signal from a user through the microphone;
- determine whether a predetermined output timing for outputting a back-channel signal has occurred in response to the received voice signal;
- store, in the memory, the voice signal received up to the predetermined output timing when the predetermined output timing has occurred;
- generate voice recognition results based on the stored voice signal;
- determine whether text according to the voice recognition results indicates a paragraph boundary point or a sentence end point;
- and
- output back-channel signal information having a predetermined first length or more for displaying reaction information corresponding the stored voice signal when the text indicates the paragraph boundary point or the sentence end point.
