Technical Field

The present invention belongs to the field of artificial intelligence technology, and in particular relates to a control method and terminal equipment for a voice dialogue robot.

Background Art

With the development of intelligent voice technology, voice-activated conversational robots, represented by smart speakers, have become widely used. Existing voice-activated conversational robots have achieved human-machine voice interaction with users, answering questions or executing corresponding control functions based on the user's voice information. Therefore, the development of voice-activated conversational robots has brought great convenience to people's lives.

However, the voice chatbots currently available on the market typically operate independently. If multiple voice chatbots are located in the same environment but are separated by large distances, users who wish to control multiple robots simultaneously must walk to each robot's location before controlling them individually. This situation results in relatively low control efficiency for the voice chatbots.

DETAILED DESCRIPTION

In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In the following embodiments of the present invention, in order to distinguish the voice messages sent or received by the voice dialogue robot at different times, each voice message is named "first voice message", "second voice message", "third voice message" and "fourth voice message". It is worth noting that the relationship between the voice messages is determined by their functional use and internal logic. "First", "second", "third" and "fourth" are not used to limit the execution order of the voice messages, and therefore their serial numbers should not constitute any limitation on the implementation process of the embodiments of the present invention.

In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

FIG1 shows the implementation process of the control method of the voice dialogue robot provided by an embodiment of the present invention, which includes steps S101 to S104. The specific implementation principles of each step are as follows:

S101: Broadcasting a robot search signal, and upon receiving response information based on the robot search signal, extracting an identification code of the voice dialogue robot from the response information.

In the embodiment of the present invention, the execution subject of each step is a voice dialogue robot, which is called a local voice dialogue robot to distinguish it from various remote voice dialogue robots.

During operation, the local voice dialogue robot continuously emits a robot search signal. When other voice dialogue robots within the signal's transmission range detect this robot search signal, they respond with information based on the robot search signal. Because each voice dialogue robot within the signal's transmission range is located at a different point from the local voice dialogue robot, each voice dialogue robot within the signal's transmission range is referred to as a remote voice dialogue robot.

The response message sent by the remote voice dialogue robot includes the identification code of the voice dialogue robot. The identification code is used to uniquely identify a voice dialogue robot. The identification code can be, for example, a PIN (Personal Identification Number).

Preferably, the response information also includes the device name of the voice dialogue robot. The device name is the name of the voice dialogue robot, which is pre-set by the manufacturer when it leaves the factory and can also be customized by the user.

The identification code and device name included in the same response message are stored in a record in the data table to determine the correspondence between each identification code and its device name. At the same time, the identification code and device name of the local voice dialogue robot are also stored in a record in the data table, and the record is marked as a local record.

S102: Establishing a connection with the voice dialogue robot based on the identification code.

Based on the received identification codes, the local voice chatbot automatically pairs with the remote voice chatbots and sends a link establishment request to each remote voice chatbot. Once the link is established, two-way data or voice communication can be established between the local voice chatbot and the remote voice chatbot.

S103: Acquire a first voice message sent by a user, and determine a control mode of the first voice message.

When the user needs to control the voice dialogue robot, a voice message will be sent to the local voice dialogue robot at the user's current location. The voice message received by the local voice dialogue robot may be, for example, "play the third song in the song list."

In the embodiment of the present invention, different voice messages correspond to different control modes. The control mode indicates how the local voice dialogue robot synchronizes the voice messages. The control modes include stand-alone mode, multicast mode, and broadcast mode.

The stand-alone mode means that the local voice dialogue robot does not need to synchronize the voice information, that is, the control instructions matching the voice information only need to be executed by the local voice dialogue robot.

The multicast mode means that the local voice dialogue robot needs to synchronize the voice information to one or more remote voice dialogue robots.

The broadcast mode means that the local voice dialogue robot needs to synchronize the voice information to all remote voice dialogue robots that are currently connected.

The control mode of the voice information can be preset by the user in the parameter information of the local voice dialogue robot. For example, in the parameter information, the control mode of the voice information of the local voice dialogue robot is uniformly set to the broadcast mode.

As an embodiment of the present invention, as shown in FIG2 , the above S103 specifically includes:

S1031: Analyze the first voice message sent by the user to obtain keywords in the first voice message.

In the embodiment of the present invention, when a voice message sent by a user is received, the voice message is analyzed by a preset voice recognition algorithm.

Specifically, the speech recognition process includes: framing the speech information using a preset frame length and frame shift to obtain M (M is an integer greater than zero) frame waveforms; extracting acoustic features, such as MFCC (Mel-Frequency Cepstral Coefficients), from each frame waveform to obtain an N-dimensional vector corresponding to each frame waveform. Since the pronunciation of a word is composed of phonemes, a phonetic unit finer than a phoneme, and a phoneme contains three states, in embodiments of the present invention, the N-dimensional vector corresponding to each frame waveform is input into a pre-acquired acoustic model, such as a hidden Markov model, to output the probabilities of each state corresponding to the frame waveform; the state with the highest probability is determined as the state corresponding to the frame waveform. By determining the states corresponding to each frame waveform, every three consecutive states are combined into a phoneme. After combining multiple phonemes, the word corresponding to the speech information is output, thereby achieving the conversion of speech information into text.

After converting the voice information into corresponding text and performing word segmentation on the text, each word segmented is a keyword of the voice information.

S1032: If the keyword is different from any of the device names stored in the data table, determining that the control mode of the first voice information is a broadcast mode.

The data table generated in S101 stores the device names of each remote voice dialogue robot. Each keyword obtained at the current moment is compared with each device name in the data table to determine whether each keyword is the same as any device name in the data table.

For each keyword in the voice information, if it is different from any device name in the data table, it is determined that the control mode of the voice information sent by the user is the broadcast mode.

In an embodiment of the present invention, by real-time analysis of keywords in voice information and determining that the control mode of the voice information is a broadcast mode when the keywords are different from the device name in the data table, personalized setting of the control mode of the voice information is achieved, avoiding the user having to uniformly set the control mode of all voice information in the parameter information of the voice dialogue robot on this end, thereby improving the flexibility of setting the control mode, and thus allowing the user to send voice information of different control modes based on the judgment rules of the control mode, thereby improving the control flexibility of the voice dialogue robot.

S104: If the control mode is the broadcast mode, the first voice information is synchronized to the voice dialogue robot associated with the identification code, so that the voice dialogue robot executes the control instruction matching the first voice information.

When the control mode of the voice information is the broadcast mode, the stored identification codes are read in the data table, and the voice information is synchronously sent to the remote voice dialogue robots associated with each identification code, so that each voice dialogue robot that receives the voice information can execute the control instructions matching the voice information.

Preferably, for each voice dialogue robot that receives the voice information, the voice information can also be synchronized to other remote voice dialogue robots based on the above steps S101 to S104, thereby expanding the propagation range of the voice information and realizing synchronous control of voice dialogue robots with a farther distribution range.

In an embodiment of the present invention, by broadcasting a robot search signal, it is possible to detect each voice dialogue robot within the signal search range, thereby automatically obtaining the identification codes of each voice dialogue robot in a different location from the local voice dialogue robot and achieving communication connection with the remote voice dialogue robot; by making the voice information correspond to the stand-alone mode, multicast mode, or broadcast mode, and accurately determining the control mode of the voice information according to the actual needs of the user, it is ensured that when the control mode of the voice information received by the user is the broadcast mode, the voice information can be synchronized to each connected voice dialogue robot, thereby enabling the user to voice control multiple voice dialogue robots at distant locations based on a voice message sent by the user. The user no longer needs to go to the location of each voice dialogue robot to perform voice control, thus improving the control efficiency of the voice dialogue robot.

On the basis of the above embodiments, as another embodiment of the present invention, the synchronization method of voice information when the control mode is the multicast mode is further limited. As shown in Figure 3, after the above S104, it also includes:

S105: If the control mode is a multicast mode, then in a data table storing the correspondence between identification codes and device names, the identification code corresponding to the device name carried by the first voice message is searched, and the correspondence between the identification code and the device name is obtained from the response information.

For any keyword in the voice message, if it is the same as the device name of the local voice dialogue robot, the control mode of the voice message is determined to be stand-alone mode; if it is the same as any device name other than the local device name in the data table, the control mode of the voice message is determined to be multicast mode, and it is determined that the voice message sent by the user carries the device name.

When the control mode of the voice information is the multicast mode, the identification code corresponding to the device name carried in the voice information is read from the data table.

S106: Synchronize the first voice information to the voice dialogue robot associated with the found identification code, so that the voice dialogue robot executes the control instruction matching the first voice information.

Based on the identification codes read at the current moment, the voice dialogue robots associated with the identification codes are selected from the currently connected remote voice dialogue robots. Only the voice messages sent by the user are synchronized to the selected voice dialogue robots.

The embodiments of the present invention are applicable to scenarios where a user needs to control multiple voice dialogue robots specified in an area. For example, if there are five voice dialogue robots distributed in the current area, and the device names of the voice dialogue robots are Alice, Bob, Colly, Doggy, and Ella, respectively, and the user is currently at Alice's location, then when the user needs to control Alice, Colly, and Ella to play Wang Leehom's songs at the same time, the user can send a voice message to Alice, "Alice, you play Wang Leehom's songs with Bob and Ella." At this time, Alice, who receives the voice message, will synchronize the voice message to Bob and Ella, thereby ensuring that Alice, Colly, and Ella can all obtain the voice message and jointly execute the control instructions that match the voice message.

In an embodiment of the present invention, in multicast mode, by identifying the device name carried in the voice information, obtaining the identification code corresponding to the device name, and synchronizing the voice information sent by the user to each voice dialogue robot associated with the identification code, the user can accurately send voice information carrying different device names, thereby realizing remote synchronous control of the specified voice dialogue robot, avoiding the situation where the voice information can only be broadcast to all connected voice dialogue robots when notifying the remote voice dialogue robot, thereby realizing effective control of the voice dialogue robot and avoiding the transmission of invalid information.

As another embodiment of the present invention, as shown in FIG4 , the control method of the voice dialogue robot further includes:

S107: If the second voice information synchronized by the voice dialogue robot is received, the function type of the second voice information is determined.

The function type of a voice message refers to the function achieved by the voice chatbot after executing the control instructions that match the voice message. Voice message function types include, but are not limited to, timed reminders, music playback, and question answering.

If a user sends a voice message, and the voice message is used to control the voice dialogue robot to issue a reminder when the preset time arrives, the function type of the voice message is a timed reminder.

When receiving a voice message synchronized from any remote voice dialogue robot to the local voice dialogue robot, the voice message is parsed to determine the function type of the voice message.

For example, if it is recognized that the voice information contains time information and the word "reminder", the function type of the voice information is determined to be a timed reminder.

S108: If the function type is a timed reminder, when the reminder time corresponding to the second voice message arrives, the distance between the current time and the user's location is detected.

The time information contained in the voice message is the reminder time corresponding to the voice message. If the current system time of the local voice dialogue robot is the reminder time, the local voice dialogue robot detects the real-time location distance between it and the user.

In one example, the location distance may be detected by: obtaining the location information reported in real time by the locator carried by the user to determine the user's geographic location; calculating the distance between the geographic location and the location of the local voice dialogue robot; and determining the calculated distance as the location distance between the local voice dialogue robot and the user at the current moment.

S109: If the location distance is less than a preset threshold, a prompt message is issued.

If the distance is less than a preset threshold, the local voice dialogue robot will issue a prompt message so that the user can receive the prompt message. The prompt message includes but is not limited to audio prompts and flashing prompts.

In another embodiment of the present invention, the local voice dialogue robot activates its built-in camera to scan for faces within its camera area. In this case, the camera's maximum camera range is set to the preset threshold. If a face is detected within the maximum camera range, the user is determined to be less than the preset threshold, and a prompt is issued.

Preferably, in the above example, if a human face is detected within the maximum camera range, the facial features of that face are compared with the facial features of a preset user to determine whether the person currently within the camera range is the owner of the voice dialogue robot. If so, it is determined that the distance between the user and the local voice dialogue robot is less than a preset threshold, and a prompt message is issued; if not, it is determined that the distance between the user and the local voice dialogue robot is greater than the preset threshold, and no prompt message is issued.

In an embodiment of the present invention, after receiving a timed reminder voice message, the user can be determined to be in the vicinity of the local voice dialogue robot by determining in real time at the reminder moment whether the distance between the user and the local voice dialogue robot is less than a preset threshold. If the user is not in the vicinity of the local voice dialogue robot, it will be difficult for the user to receive the reminder message from the local voice dialogue robot. Therefore, the reminder message is only issued when the distance between the user and the local voice dialogue robot is less than the preset threshold, achieving a more effective reminder effect. At the same time, it also avoids multiple voice dialogue robots that receive voice messages from issuing reminders at the same time, thereby reducing the energy consumption of the voice dialogue robot. In addition, by recognizing the facial features of the detected human face, the voice dialogue robot can accurately issue reminders to the owner of the voice dialogue robot, thereby improving the accuracy of the reminder.

As an embodiment of the present invention, as shown in FIG5 , the above S106 specifically includes:

S1061: Obtain the local device name.

In multicast mode, before the local voice dialogue robot synchronizes the voice information sent by the user to one or more designated remote voice dialogue robots, it first obtains the device name pre-stored by the local voice dialogue robot, that is, the local device name.

S1062: Delete the voice segment containing the local device name in the first voice information.

The voice message sent by the user is identified to determine the voice segment containing the local device name. The voice segment is intercepted and deleted so that the voice message sent by the user no longer carries the local device name.

S1063: Synchronize the first voice information after deleting the voice segment to the voice dialogue robot associated with the found identification code, so that the voice dialogue robot executes a control instruction that matches the first voice information after deleting the voice segment.

According to the identification codes found in the above S105, the remote voice dialogue robots to be synchronized are determined, and the voice message no longer carrying the local device name is sent to the voice dialogue robots to be synchronized.

For example, if a user sends a voice message to Alice saying "Alice, Bob, and Ella play Wang Leehom's songs together", then since Alice's local device name is "Alice", the voice segment containing "Alice" is deleted from the voice message, resulting in "Bob and Ella play Wang Leehom's songs together"; Alice synchronizes the voice message "Bob and Ella play Wang Leehom's songs together" to Bob and Ella.

Since each remote voice dialogue robot executes steps S101 to S106 above upon receiving the synchronized voice information, i.e., resynchronizing the voice information with the corresponding voice dialogue robot based on the device names carried in the voice information, in this embodiment of the present invention, by deleting the voice segments containing the local device name from the voice information, each remote voice dialogue robot will no longer parse the local device name upon receiving the synchronized voice information, and thus will not repeatedly synchronize the voice information with the source end, thereby improving information synchronization efficiency.

In one embodiment of the present invention, based on the aforementioned embodiments, if a voice message synchronized from a remote voice dialogue robot is received, a timing function is activated. If a voice message synchronized from the remote voice dialogue robot is received again within a preset time period, the similarity between these voice messages is calculated. If the similarity exceeds a preset threshold, the voice messages are determined to be the same voice message actually uttered by the user. In this case, the voice message with the strongest signal strength is selected to execute the control instruction that matches the voice message.

In an embodiment of the present invention, since the voice message sent by the user may be detected by multiple nearby voice dialogue robots at the same time, under broadcast mode or multicast mode, the multiple voice dialogue robots will synchronize the voice message to each remote voice dialogue robot. Therefore, any remote voice dialogue robot may receive multiple voice messages with different signal strengths but the same content. In this case, by determining the similarity of each voice message received successively within a preset time period, and when the similarity is greater than a threshold, filtering out the voice message with the strongest signal strength, it is possible to prevent the voice dialogue robot from repeatedly executing the same control instruction. Since the filtered voice message has the strongest signal strength, it is possible to improve the accuracy of recognition when identifying the control instruction that matches the voice message.

It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
