Patent Application Titled "Dialogue Processing Apparatus, a Vehicle Having Same, and a Dialogue Processing Method" Published Online (USPTO 20180182382)

By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Lee, Kyung Chul (Seongnam-Si, KR), filed on June 26, 2017, was made available online on July 5, 2018.

The assignee for this patent application is Hyundai Motor Company.

Reporters obtained the following quote from the background information supplied by the inventors: "Embodiments of the present disclosure relate to a dialogue processing apparatus, a vehicle having a dialogue processing apparatus, and a dialogue processing method.

"As technologies for vehicles are developed, various functions for user convenience have been provided in addition to the driving function, which is a basic function of the vehicle.

"As the functions performed by the vehicle become variable, the user operation load has increased. The increase of the user operation load has reduced the concentration of the user during vehicle operation, thereby interfering with safe driving. In addition, a user who is unfamiliar with the operation of the vehicle cannot properly utilize the functions performed by the vehicle."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "It is an aspect of the present disclosure to provide a dialogue processing apparatus that can monitor an intensity of an acoustic signal that is input in real time and that can determine that speech recognition has started and that the intensity of the input acoustic signal is equal to or greater than a reference value. The disclosed dialogue processing apparatus allows a user to start speech recognition by an utterance without performing an operation for an additional trigger.

"It is another aspect of the present disclosure to provide a dialogue processing apparatus that is capable of providing a response and service appropriate for a user's intention by determining whether a dialogue is continuously performed or whether a dialogue with a new subject has started. In this aspect, the determining is based on a domain and a keyword extracted from an input speech.

"The present disclosure is also directed to a dialogue processing method and to a vehicle, each having the dialogue processing apparatuses as described above. Additional aspects of the present disclosure are set forth, in part, in the detailed description below and, in part, will be apparent to those of ordinary skill in the art from the description, or may be learned by practice of the present disclosure.

"In accordance with one aspect of the present disclosure, a dialogue processing apparatus includes a monitor configured to compare a level of an input signal with a reference level in real time, and configured to determine that a user's speech is input when the level of the input signal is greater than the reference level. The dialogue processing apparatus also includes a speech recognizer configured to output an utterance in the form of text by performing speech recognition on the input signal when it is determined that the user's speech is input. The dialogue processing apparatus further includes a natural language processor configured to extract a domain and a keyword based on the utterance and includes a dialogue manager configured to determine whether a previous context is maintained based on the domain and the keyword.

"In one embodiment, the reference level is determined based on a level of a background signal that is input in a state in which a user's speech is not uttered.

"In one embodiment, the dialogue processing apparatus further includes a storage device configured to store the level of the background signal. In this embodiment, the storage device determines that the input signal is the background signal when the level of the input signal is equal to or less than the reference level. The storage device in this embodiment also updates the stored level of the background signal using the level of the input signal.

"In one embodiment, the dialogue manager determines whether a previous context that is started is present based on information related to a pre-stored previous context. When the previous context that is started is present, the dialogue manager may determine whether the previous context that is started is ended. When a predetermined reference time is expired from when the previous context is started, the dialogue manager may determine that the previous context is ended. When the reference is not expired, the dialogue manager may determine whether a context is changed by comparing information related to the previous context with information related to a current context.

"In one embodiment, the dialogue manager determines whether the context is changed by comparing a domain and a keyword extracted from the previous context with a domain and a keyword extracted from the current context. When it is determined that the context is not changed, the dialogue manager may provide a dialogue and service having a continuity with a previous dialogue and service performed in the previous context. When it is determined that the context is changed, the dialogue manager may end the previous context and start the current context as a new context.

"In accordance with another aspect of the present disclosure, a vehicle includes a microphone configured to receive a sound by always being opened, and configured to convert the input sound into an electrical input signal. The vehicle also includes a monitor configured to compare a level of the input signal with a reference level in real time, and configured to determine that a user's speech is input when the level of the input signal is greater than the reference level. The vehicle further includes a speech recognizer configured to output an utterance in the form of text by performing speech recognition on the input signal when it is determined that the user's speech is input. The vehicle also includes a natural language processor configured to extract a domain and a keyword based on the utterance, and includes a dialogue manager configured to determine whether a previous context is maintained based on the domain and the keyword.

"In one embodiment, the reference level is determined based on a level of a background signal that is input in a state in which a user's speech is not uttered.

"In one embodiment, the vehicle further includes a storage device configured to store the level of the background signal. In this embodiment, the storage device determines that the input signal is the background signal when the level of the input signal is equal to or less than the reference level. The storage device in this embodiment also updates the stored level of the background signal using the level of the input signal.

"In one embodiment, the dialogue manager determines whether a previous context that is started is present based on information related to a pre-stored previous context.

"When the previous context that is started is present, the dialogue manager may determine whether the previous context that is started is ended. When a predetermined reference time is expired from when the previous context is started, the dialogue manager may determine that the previous context is ended. When the reference is not expired, the dialogue manager may determine whether a context is changed by comparing information related to the previous context with information related to a current context.

"In one embodiment, the dialogue manager determines whether the context is changed by comparing a previous domain and a keyword extracted from the previous context with a domain and a keyword extracted from the current context.

"When it is determined that the context is not changed, the dialogue manager may provide a dialogue and service having a continuity with a previous dialogue and service performed in the previous context. When it is determined that the context is changed, the dialogue manager may end the previous context and start the current context as a new context.

"In accordance with another aspect of the present disclosure, a dialogue processing method includes comparing a level of an input signal input via a microphone that is always opened with a reference level in real time. The dialogue processing method also includes determining that a user's speech is input when the level of the input signal is greater than the reference level. The dialogue processing method further includes performing a dialogue processing process by performing speech recognition on the input signal when it is determined that the user's speech is input.

"In one embodiment, the reference level is determined based on a level of a background signal that is input in a state in which the user's speech is not uttered.

"In one embodiment, the dialogue processing method further includes determining that the input signal is the background signal when the level of the input signal is equal to or less than the reference level and includes updating the stored level of the background signal using the level of the input signal.

"In one embodiment, the performance of the dialogue processing process includes determining whether a previous context that is started is present based on information related to a pre-stored previous context.

"In one embodiment, the performance of the dialogue processing process includes determining, when the previous context that is started is present, whether the previous context that is started is ended.

"In one embodiment, the determination of whether the previous context that is started is ended includes determining that the previous context is ended when a predetermined reference time is expired from when the previous context is started.

"In one embodiment, the performance of the dialogue processing process includes determining whether a context is changed by comparing information related to the previous context with information related to a current context, when a predetermined reference time is not expired.

"In one embodiment, the determination of whether a context is changed includes determining whether the context is changed by comparing a previous domain and a keyword extracted from the previous context with a domain and a keyword extracted from the current context.

"In one embodiment, the performance of the dialogue processing process includes providing a dialogue and service having a continuity with a previous dialogue and service performed in the previous context when it is determined that the context is not changed.

"In one embodiment, the performance of the dialogue processing process includes terminating the previous context and starting the current context as a new context when it is determined that the context is changed."
