Method and apparatus for providing service for voice interaction in vehicle

A method performed by an apparatus for providing a voice interaction service, the method comprising:

• determining, by a processor, a confidence value using a first spoken voice of a user;
• comparing, by the processor, the confidence value with a predefined value to determine a voice interaction mode, the voice interaction mode including a first mode and a second mode, the first mode being a mode for providing a response to the user, the second mode being a mode for performing a control operation, the control operation being an operation of understanding the user's spoken voice and controlling at least one in-vehicle device in accordance with the user's intent;
• determining, by the processor, a response intent using the first spoken voice based on determining the voice interaction mode as the first mode, the response intent being an intent to be conveyed to the user;
• providing, by the processor, a feedback to the user using the response intent;
• and
• maintaining or changing, by the processor, the voice interaction mode based on whether a second spoken voice of the user includes an intent slot, and the feedback,
• wherein the first spoken voice is a voice spoken by the user before the feedback is provided, the second spoken voice is a voice spoken by the user after the feedback is provided, and the intent slot is a slot reflecting a user's intent.

A non-transitory computer-readable recording medium storing instructions, the instructions executed by a computer causing the computer to perform:

• determining a confidence value using a first spoken voice of a user;
• comparing the confidence value with a predefined value to determine a voice interaction mode, the voice interaction mode including a first mode and a second mode, the first mode being a mode for providing a response to the user, the second mode being a mode for performing a control operation, the control operation being an operation of understanding the user's spoken voice and controlling at least one in-vehicle device in accordance with the user's intent;
• determining a response intent using the first spoken voice based on determining the voice interaction mode as the first mode, the response intent being an intent to be conveyed to the user;
• providing a feedback to the user using the response intent;
• and
• maintaining or changing the voice interaction mode based on whether a second spoken voice of the user includes an intent slot, and the feedback,
• wherein the first spoken voice is a voice spoken by the user before the feedback is provided, the second spoken voice is a voice spoken by the user after the feedback is provided, and the intent slot is a slot reflecting a user's intent.
