Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A method of masking an audio advertisement, a computer-readable storage medium, and an electronic device according to embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, the method provided in this embodiment is a method for shielding audio advertisements based on a car terminal, and includes the following steps:
step S110, generating a shielding characteristic database, and identifying whether audio advertisements appear in the audio information according to the voice characteristics in the shielding characteristic database, wherein the voice characteristics of the audio advertisements are stored in the shielding characteristic database.
Specifically, in this embodiment, a masking feature database may be generated by the speech engine and whether an audio advertisement appears in the audio information may be identified according to speech characteristics in the masking feature database. The speech engine is primarily used for speech recognition, and can convert audio information into computer-readable input and recognize speech characteristics in the audio information.
In one embodiment, as shown in fig. 2, generating the mask feature database comprises:
and step S111, receiving a shielding starting instruction, and acquiring an advertisement audio signal according to the shielding starting instruction.
Wherein, the starting shielding instruction is an instruction sent by a user. Generally, when a user listens to an audio program, if an advertisement is inserted into the audio program, the user may send a start masking instruction to the car end. As shown in fig. 3, fig. 3 is a time axis for generating a shielding feature database, and a user may send a start shielding instruction within a period of time after a time node at which an advertisement appears, and a car-end receives the start shielding instruction and starts to collect an advertisement audio signal according to the start shielding. In this embodiment, the start masking command may be a voice start masking command and a touch start masking command. Specifically, a user can input a touch start shielding instruction through a button arranged on a vehicle machine or through a vehicle machine display device; or the car machine system is integrated with a voice recognition module, a user sends a voice starting shielding instruction through voice, and the voice recognition module collects the voice of the user and receives the voice starting shielding instruction.
If the vehicle-mounted system receives the starting shielding instruction and indicates that the current audio signal is the advertisement audio signal, the vehicle-mounted system can collect the advertisement audio signal through the microphone.
Further, as shown in fig. 3, when the car-in-vehicle system receives the start-up masking command, it starts timing at the same time to record the advertisement duration of the corresponding audio advertisement.
And step S113, receiving the shielding ending instruction, and ending the collection of the advertisement audio signal according to the shielding ending instruction.
As shown in fig. 3, within a period of time after the time node of advertisement ending, the user may issue an ending shielding instruction to the vehicle end. Similarly, the end mask instruction may be a voice end mask instruction or a touch end mask instruction. Specifically, a user can input a touch ending shielding instruction through a button arranged on a vehicle machine or through a vehicle machine display device; or the vehicle-mounted machine system is integrated with a voice recognition module, a user issues a voice ending shielding instruction through voice, and the voice recognition module collects the voice of the user and receives the voice ending shielding instruction so as to end the collection of the advertisement audio signal.
Step S115, sending the collected advertisement audio signal to a voice engine so that the voice engine can identify the voice characteristic of the collected advertisement audio signal and generate a shielding characteristic database according to the voice characteristic of the advertisement audio signal.
In this embodiment, a speech engine may be used to automatically identify the collected advertisement audio, convert the advertisement audio into text, extract the speech characteristics of the advertisement audio signal, and store the speech characteristics to form a mask feature database. The voice characteristics of the advertisement audio signal may include keyword information and brand information, where the keyword information may be "discount", "free", "saving money", or a unique keyword corresponding to each advertisement, and it can be understood that, in order to improve the accuracy of advertisement identification, there may be many keyword information of each advertisement.
Further, as shown in fig. 3, the in-vehicle system finishes timing and counts the advertisement duration while receiving the shielding instruction. When the voice characteristics of the audio advertisements are stored in the shielding characteristic database, the vehicle-mounted system simultaneously stores the corresponding advertisement duration. Thus, the mask feature database contains the voice characteristics of the audio advertisement and the corresponding advertisement duration. When a user hears a new advertisement, the car machine system can execute the operation so as to learn different audio advertisements and improve the content of the shielding characteristic database.
Specifically, as shown in fig. 4, after the mask feature database is generated, when the radio is turned on, the car terminal collects the audio signal of the radio in real time and sends the audio signal to the speech engine, and the speech engine determines whether the speech characteristics of the collected audio signal match the speech characteristics stored in the mask feature database.
In step S130, if it is identified that the audio advertisement appears in the audio information, the audio advertisement is masked.
If the voice characteristics of the collected audio signals are matched with the voice characteristics stored in the shielding characteristic database, the currently played audio signals can be judged to be audio advertisements, and the voice engine can send shielding instructions, so that the vehicle terminal can shield the audio advertisements according to the shielding instructions.
In one embodiment, the car terminal may mute the radio to block the audio advertisement or switch to another audio channel and time the block duration, and switch back to the original audio channel to block the audio advertisement when the block business reaches the advertisement duration of the advertisement. Alternatively, the car end may also perform other user's favorite operations, such as playing music that is pre-stored in the system.
Furthermore, after the vehicle end identifies the audio advertisement being played, the vehicle end starts to time while starting to shield, and when the timing time reaches the advertisement time length corresponding to the audio advertisement in the shielding characteristic database, the vehicle end finishes shielding, so that automatic shielding is realized, the advertisement playing time length is automatically recovered by utilizing the fixed characteristic of the advertisement playing time length after shielding, and the normal use of a user is not influenced while the audio advertisement is shielded. It can be understood that, since there is an error between the time point when the user issues the start masking command and the end masking command and the time point when the advertisement starts and ends, as shown in fig. 4, there is an error between the time when the vehicle end starts to mask the advertisement and the time when the advertisement ends to mask the advertisement and the time when the advertisement starts and ends. Of course, the error is small, and the normal listening of the audio program by the user after the shielding is finished is not influenced.
It should be noted that, in the foregoing embodiment, the speech engine may be disposed at a vehicle end, or may be disposed at a cloud server, which is not limited in this application.
According to the shielding characteristic database storing the voice characteristics of the audio advertisements, whether the audio advertisements appear in the audio information is identified by utilizing the voice self-learning function of the voice engine according to the voice characteristics in the shielding characteristic database, if the audio advertisements appear in the audio information, the audio advertisements are shielded, the audio advertisements in the radio can be automatically shielded, the audio advertisements are automatically recovered by utilizing the characteristic that the playing time of the advertisements is fixed after being shielded for a period of time, the automation and intelligence level of a vehicle is improved, and the vehicle using experience of a user is improved.
In addition, another embodiment of the present application provides an electronic device, which includes a memory, a processor, and a masking program for audio advertisements, stored in the memory and executable on the processor, where the processor implements the aforementioned method for masking audio advertisements when executing the masking program for audio advertisements.
According to the electronic equipment, the audio advertisements in the radio are automatically shielded through the shielding method of the audio advertisements, the audio advertisements are automatically recovered by using the characteristic that the playing time of the advertisements is fixed after being shielded for a period of time, the automation and intelligence level of vehicles is improved, and the vehicle using experience of users is improved.
