Based on this, the embodiments of the present disclosure provide a method, an apparatus, an electronic device, a computer-readable storage medium, and a computer program product for recommending multimedia information, which can be applied to various transportation vehicles, such as airplanes, high-speed rails, ships, buses, private cars, and the like, to provide targeted and personalized multimedia information services for passengers, thereby improving the riding experience of the passengers.

As shown in fig. 1, some embodiments of the present disclosure provide a method 100 for recommending multimedia information, which includes the following steps S101 to S104.

In step S101, voiceprint information of a passenger seated in a vehicle is acquired.

In step S102, an attribute category corresponding to the passenger is determined from a plurality of attribute categories based on the voiceprint information of the passenger.

In step S103, a multimedia information mode that recommends multimedia information to the passenger is selected from the plurality of multimedia information modes according to the attribute category corresponding to the passenger and the correspondence between the plurality of attribute categories and the plurality of multimedia information modes.

In step S104, according to the selected multimedia information mode, multimedia information corresponding to the selected multimedia information mode is presented on a multimedia interaction device installed in the vehicle in association with a seat on which the passenger is seated.

Taking a vehicle as an airplane as an example, a multimedia interaction device, such as a multimedia video entertainment device, is equipped in front of or above most of the passenger seats, so that passengers can enjoy and relax during a trip, and a more comfortable and relaxed travel experience can be obtained.

In some embodiments of the present disclosure, the plurality of attribute categories includes a plurality of age categories and/or at least two gender categories. The plurality of multimedia information modes include at least two of an old man mode, a child mode, a teenager mode, a middle-aged mode, a male mode and a female mode, and each multimedia information mode is set corresponding to one attribute category. For example, in one embodiment, the plurality of attribute categories includes: child category, geriatric category, male category, and female category. The plurality of multimedia information modes include a child mode, an old man mode, a man mode, and a woman mode.

The multimedia information corresponding to the selected multimedia information mode may include: a display interface and/or multimedia content corresponding to the selected multimedia information mode. Multimedia content includes, for example, animations, movies, television shows, songs, news, web hotspots, short videos, novels, and the like. The display interface refers to an interaction style displayed by a screen of the multimedia interaction device. For example, for a child passenger, the display interface is designed as a card ventilation grid, and the recommended multimedia content on the interface is cartoons, children songs and children stories. For example, for lady passengers, the display interface is designed to be a beauty-only style, and the multimedia content recommended on the interface is beauty information, emotion episodes and entertainment news. For example, for male passengers, the display interface is designed to be a business-biased style, and the multimedia content recommended on the interface is financial information, action films and sports news. For another example, for an elderly passenger, the display interface is designed to be a Chinese style, and the multimedia content recommended on the interface is art, revolutionary movies, and classical songs.

In the disclosed embodiment, multimedia information is recommended for the passenger based on the passenger's voiceprint. Voiceprints are a spectrum of sound waves that are not only characteristic, but also relatively stable. After the adult, the voice of a person can be kept relatively stable for a long time, and whether a speaker deliberately imitates the voice and tone of other people or speaks in whisper with slight voice, even if the imitation is completely vivid, the voice print of the speaker is always different. Therefore, the attribute type of the passenger can be judged according to the voiceprint, and the voiceprint can be used for identity recognition.

In the scheme of the embodiment of the disclosure, after a passenger sits, an attribute category corresponding to the passenger is determined according to voiceprint information of the passenger, then a multimedia information mode recommending multimedia information to the passenger is determined according to the attribute category corresponding to the passenger and corresponding relations between a plurality of attribute categories and a plurality of multimedia information modes, and then the recommended multimedia information is displayed on the multimedia interaction device. Therefore, the multimedia information recommended to the passengers by the multimedia interaction equipment is not uniform, and the targeted and personalized recommendation is carried out according to the attribute types corresponding to the passengers, so that the riding experience of the passengers can be improved, and the journey experience is better.

In some embodiments of the present disclosure, the aforementioned step S101 includes: and responding to the voice awakening instruction of the passenger to the multimedia interaction device, and acquiring voiceprint information carried in the voice awakening instruction sent by the passenger. After the passenger sits, the passenger sends a voice wake-up instruction, for example, sends a voice wake-up word "XX hello", at which time the multimedia interaction device is woken up and obtains the voiceprint information of the passenger from the voice wake-up word sent by the passenger.

In other embodiments of the present disclosure, the foregoing step S101 includes: and responding to a non-voice operation awakening instruction of the passenger to the multimedia interaction device, and acquiring voiceprint information carried in the voice of the passenger. After the passenger sits, the passenger wakes up the multimedia interaction device by clicking a physical key or a virtual key matched with the multimedia interaction device, and then voice (not limited to a fixed wake-up word, but any sentence or word in a conversation) sent by the passenger is captured by the multimedia interaction device and voiceprint information is obtained from the voice.

In still other embodiments of the present disclosure, the step S101 includes: and acquiring voiceprint information carried in the voice of the passenger in real time or according to a set time interval. The voiceprint acquisition module of the multimedia interaction device is in a working state in real time or according to a set time interval, and when a passenger on a seat is replaced, voiceprint information of the passenger can be acquired in time, so that personalized multimedia information recommendation service is provided for the passenger according to the steps of the method.

In some embodiments of the present disclosure, the aforementioned step S101 includes: voiceprint information carried in a voice in a set space associated with a seat on which a passenger sits is acquired. In the embodiment, the setting spaces associated with different seats are different, and the multimedia interaction device can capture voiceprint information carried in voice generated by a passenger in the corresponding associated setting space, so that after the passenger sits on the seat, the voiceprint information carried in the voice can be captured by the corresponding multimedia interaction device as long as the voice is generated, and the passenger does not need to manually operate the physical device.

In other embodiments of the present disclosure, the foregoing step S101 includes: voiceprint information carried in a voice input by a voice input device associated with a seat on which a passenger is seated is acquired. In this embodiment, after the passenger sits, the passenger can send out voice through a microphone specially configured for the multimedia interaction device or an earphone containing the microphone, so that the multimedia interaction device can quickly and accurately capture voiceprint information carried in the voice.

In some embodiments of the present disclosure, the aforementioned step S102 includes the following sub-steps one and two.

In sub-step one, the voiceprint characteristics of the passenger are identified from the voiceprint information of the passenger.

In the second sub-step, according to the voiceprint characteristics of the passenger, the attribute category corresponding to the passenger is determined from the plurality of attribute categories.

The voiceprint features include formants, wavelengths, frequencies, intensities, rhythms, and the like, regardless of the speech content. The frequency value and the trend of the resonance peak are the most stable characteristics, and the resonance peak has strong specificity and the highest utilization value.

As shown in fig. 2, a method 200 for recommending multimedia information according to some embodiments of the present disclosure further includes the following steps S201 to S204 based on the foregoing embodiments.

In step S201, in response to the voiceprint feature library not including the identified voiceprint feature, the identified voiceprint feature is stored in the voiceprint feature library, and an Identity (ID) corresponding to the identified voiceprint feature is created for the passenger.

In step S202, the operation record of the passenger on the multimedia information in the predetermined time period is stored in the storage device.

In step S203, the preference of the passenger is determined from the stored operation record.

In step S204, a correspondence between the identity of the passenger and the preferences of the passenger is established.

As mentioned above, voiceprints can be used for identification due to their specificity and stability. The voiceprint characteristics of the passengers and the matched identification marks are stored in the voiceprint characteristic library, and when the passengers take the vehicle next time and use the multimedia interaction device, the identification marks of the passengers can be identified through the voiceprint characteristics of the passengers, so that the multimedia information corresponding to the preferences of the passengers can be recommended to the passengers.

In one embodiment, determining the preferences of the passenger based on the stored operation records comprises: determining the operation frequency of the passenger on the multimedia information from the stored operation records; and determining the preference of the passenger according to the operation frequency of the passenger on the multimedia information. The passenger's preference for multimedia information is typically reflected in the frequency of their operation on the multimedia information, e.g., a passenger prefers to watch a spyware, which is typically clicked more frequently than other types of dramas.

As shown in fig. 3, the method 300 for recommending multimedia information according to some embodiments of the present disclosure further includes the following steps S301 to S304 on the basis that the correspondence between the identity of the passenger and the preference of the passenger is established.

In step S301, in response to the voiceprint feature library including the identified voiceprint features, an identity corresponding to the identified voiceprint features is determined.

In step S302, the preferences of the passenger are determined according to the correspondence between the identity of the passenger and the preferences of the passenger.

In step S303, multimedia information corresponding to the preference of the passenger is acquired.

In step S304, multimedia information corresponding to the preference of the passenger is presented on the multimedia interacting device.

When the passenger uses the multimedia interactive device on the vehicle for the first time, the multimedia interactive device recommends the multimedia information corresponding to the attribute class thereof to the passenger with reference to steps S101 to S104 of the aforementioned method 100 for recommending multimedia information. Since the voiceprint feature library does not include the corresponding voiceprint feature of the passenger, the multimedia interaction device establishes the correspondence between the identification and the preference for the passenger when the passenger uses the voiceprint feature library.

When the passenger takes the vehicle again and uses the multimedia interaction device, the multimedia interaction device recommends the multimedia information corresponding to the preference of the passenger for the passenger according to the established corresponding relation between the identity of the passenger and the preference of the passenger. For example, a passenger with identity 0001 may correspond to a preference of "spyware", a passenger with identity 0002 may correspond to a preference of "romance", a passenger with identity 0003 may correspond to a preference of "kyoto art", and so on. When the identity mark corresponding to the voiceprint feature of the passenger is 0001, a plurality of spyware dramas serving as recommended multimedia information contents are displayed on the multimedia interaction equipment, and meanwhile, the display interface can be displayed in a spyware theme background style.

In the above embodiments of the present disclosure, the voiceprint feature library may be located in a cloud server or a multimedia interaction device, and the storage device may be located in the cloud server or the multimedia interaction device. In some embodiments, the multimedia interaction device and the cloud server perform data synchronization through a wireless network, and the voiceprint feature library and the storage device may perform data synchronization update in real time, at certain time intervals, or when a connection is made over the network. Therefore, the multimedia interaction device can perform personalized recommendation according to the preference of the passenger when the passenger takes the vehicle, whether the passenger takes the same vehicle or not, and whether the passenger sits in the same seat or not, so that the riding experience of the passenger is further improved, and the journey experience is better.
