Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. A non-transitory computer-readable recording medium on which a program recorded thereon for causing a computer to function as a sequential utterance estimation apparatus comprising:
keyword detection circuitry configured to generate a keyword detection result indicating a result of detecting an utterance of a predetermined keyword from an input voice;
voice detection circuitry configured to generate a voice section detection result indicating a result of detecting a voice section from the input voice;
sequential utterance detection circuitry configured to generate a sequential utterance detection result indicating that a sequential utterance has been made if the keyword detection result indicates that the keyword has been detected, and if the voice section detection result indicates that the voice section has been detected;
a response sound output circuitry configured to output a predetermined response sound if the keyword detection result indicates that the keyword has been detected and if the sequential utterance detection result does not indicate that a sequential utterance has been detected; and
target sound output circuitry configured to output, as a target sound, the input voice delayed by a length of the response sound if the keyword detection result indicates that the keyword has been detected and if the sequential utterance detection result does not indicate that a sequential utterance has been detected, and output the input voice that is not delayed as the target sound if the keyword detection result indicates that the keyword has been detected and if the sequential utterance detection result indicates that a sequential utterance has been detected.
