Description

Wake-up control method and device and computer storage medium

Technical Field

The present disclosure relates to wake-up technologies in the field of intelligence, and in particular, to a wake-up control method and apparatus, and a computer storage medium.

Background

Artificial Intelligence Internet of Things (AIoT), i.e., Artificial Intelligence (AI) plus Internet of Things (IoT, Internet of Things), is also known as world wisdom interconnection, i.e., an Internet of Things that is energized by Artificial Intelligence, big data, cloud computing. An important scenario for AIoT is an intelligent smart home scenario.

An AIoT intelligent home scene based on an intelligent voice assistant is the mainstream of a future intelligent home interaction mode. Based on this, many manufacturers in the industry have quit the smart speaker product, or have the smart voice assistant built in different kinds of devices, such as smart tv, smart watch, smart alarm clock, smart car rearview mirror, etc.

When multiple intelligent voice assistant devices exist in the same or adjacent scenes, and a user calls a wakeup word, multiple voice assistants can be awakened, and a disordered response is caused. One idea for solving such problems is to coordinate and unify the devices in the cloud, that is, when a plurality of voice assistant devices belonging to the same account or a related account are awakened, the voice assistant devices in the cloud perform judgment, and select a nearby voice assistant (e.g., an awakening application that arrives first in a certain time window) to awaken. However, this processing method requires that the wake-up requirement of each voice assistant is transmitted to the cloud for processing, which results in a slow response speed of the voice assistant device to the wake-up word.

Example one

Fig. 1 is a flowchart illustrating a wake-up control method according to an exemplary embodiment, where the wake-up control method is applied to a first device having a voice interaction function, as shown in fig. 1. For example, the first device is installed with an application having a voice interaction function, such as a voice assistant application for recognizing voice information of the user. The embodiments of the present application may be applied to various first devices including, but not limited to, fixed devices and mobile devices, for example, the fixed devices include, but are not limited to: personal Computers (PC), televisions, air conditioners, wall-mounted ovens, and the like; the mobile devices include, but are not limited to: cell-phone, panel computer, wearable equipment, audio amplifier, alarm clock etc.. The wake-up control method includes the following steps.

In step S11, when the first voice message is detected, it is recognized whether the first voice message includes a preset wake-up word.

In this embodiment, the first voice information is voice data of the user collected by the first device.

In this embodiment, the preset wake-up word is a word set in the first device and used for triggering a wake-up response.

In step S12, when it is determined that the first voice message includes the preset wake-up word, monitoring whether there is first preemption state information broadcast by the second device.

Here, the second device and the first device may be the same type or different types. Illustratively, the first device and the second device are both speakers. Still illustratively, the second device is an air conditioner, and the first device is a television.

That is to say, the first device and the second device can both recognize the collected voice data sent by the user at the same time, and recognize the awakening word for triggering to awaken the user to respond according to the voice data.

In some embodiments, the second device may also detect the first voice message, and recognize whether the first voice message includes a preset wake-up word, where the preset wake-up word is also a word set in the second device for triggering a wake-up response. That is, the wake-up word for triggering the wake-up response of the second device is the same as the wake-up word for triggering the wake-up response of the first device.

In other embodiments, the second device may also detect the first voice message, and recognize whether the first voice message includes a second preset wake-up word, where the second preset wake-up word is a word set in the second device and used to trigger a wake-up response. That is, the wake-up word used to trigger the wake-up response of the second device is different from the wake-up word used to trigger the wake-up response of the first device.

In practical application, the second device and the first device are in the same intelligent system, and the intelligent system can be an intelligent home system or an intelligent office system.

Therefore, when the first voice message is determined to contain the preset awakening word, the awakening response is not immediately carried out, and whether the first preemptive state information broadcasted by the second equipment exists is monitored, so that whether the awakening response is carried out or not is determined according to the monitoring condition, and the phenomenon of false response is prevented.

In some embodiments, said monitoring whether there is first preemption-state information broadcast by the second device comprises:

Wherein the duration of the second time window is a first fixed value; or

The duration of the second time window is a first random value; or

Here, the first reference factor includes, but is not limited to, a voice intensity or a sound pressure intensity of the first voice information.

That is, the listening duration may be a fixed value, a random value, or a value adjusted according to the voice information parameter. Therefore, the awakening control method is wider in adaptability and higher in practicability.

Illustratively, the listening duration is adjusted according to the voice intensity of the first voice message, for example, if the received voice intensity is high, which indicates that the user is closer to the device, the listening duration is reduced on the basis of the first fixed value, for example, a value is reduced or multiplied by a coefficient < 1, etc.

In step S13, second preemption state information is broadcast if the first preemption state information is not monitored.

In this way, when the first preemption state information broadcast by the second device is not monitored, the second preemption state information is broadcast to compete for the wakeup response to the first voice information.

In some embodiments, the method still further comprises:

Therefore, compared with a wake-up control mode that the first device and the second device both send wake-up requests to the server to request the cloud server to determine who to wake up the response, signaling consumption can be saved.

In some embodiments, said not responding to said first voice message comprises:

Therefore, the first equipment monitors the first preemption state information broadcasted by the second equipment based on the first voice information, the second equipment wakes up and responds based on the first voice information, and the first equipment does not wake up and respond to the first voice information, so that the second equipment can be prevented from being interfered.

In some embodiments, said broadcasting said second preemption-state information comprises:

Wherein the duration of the third time window is a second fixed value; or

The duration of the third time window is a second random value; or

Here, the second reference factor includes, but is not limited to, a voice intensity or a sound pressure intensity of the first voice information.

That is, the broadcast duration may be a fixed value, a random value, or a value adjusted according to the voice information parameter. Therefore, the awakening control method is wider in adaptability and higher in practicability.

Illustratively, the adjustment is performed according to the voice intensity of the received voice information, for example, if the voice intensity of the voice information is high, it indicates that the user is closer to the device, the preemption time is increased based on the original listening duration, for example, a certain value is increased or a certain coefficient > 1 is multiplied.

Illustratively, a user speaks a "pinky" at a location in the living room, and speakers 1 and 2 at different distances from the location can both receive and recognize the "pinky" which is a wake-up word that wakes up the devices of speakers 1 and 2. In this situation, the user actually wants to wake up the loudspeaker 1 closer to the user, not the loudspeaker 2 farther from the user. In the process of monitoring the preemption state and sending the preemption state by the sound box 1, the monitoring duration or the preemption duration can be adjusted according to the sound pressure intensity, and similarly, in the process of monitoring the preemption state and sending the preemption state by the sound box 2, the monitoring duration or the preemption duration can also be adjusted according to the sound pressure intensity.

In step S14, after broadcasting the second preemption state information, a wake-up response triggered by the preset wake-up word is performed.

According to the technical scheme, the first device can locally analyze whether to wake up the response according to the monitoring condition, does not need to send a wake-up request to the cloud server to request the cloud server to determine whether to wake up the response, can save signaling consumption, can locally determine whether to wake up the response based on the preset wake-up word, and improves the response speed of the preset wake-up word.

In some embodiments, the performing a wake-up response triggered by the preset wake-up word after broadcasting the second preemption state information includes:

In this way, the first device sends a wakeup response request message to the cloud server after broadcasting the second preemption state information; if the second preemption state information is not broadcast, a wake-up response request message is not sent to the cloud server; unnecessary signaling consumption can be saved. In addition, compared with the wake-up control mode that the first device and the second device both send wake-up requests to the cloud server to request the cloud server to determine who to wake up the response, the problem of too long transmission delay caused by sending the wake-up requests to the cloud server by multiple devices can be avoided, and the response speed of the preset wake-up words is improved.

In the foregoing solution, step S14 may be replaced by:

It should be noted that the preset number of rounds may be set by the system, or may be set or adjusted by the user according to the actual situation, such as the number of devices.

In practical applications, it may happen that the first device broadcasts the second preemption state information without monitoring the first preemption state information broadcast by the second device, and at the same time, the second device broadcasts the first preemption state information without monitoring the second preemption state information broadcast by the first device. Therefore, the awakening control mode that the awakening response triggered by the preset awakening word is carried out after the number of times of broadcasting the second preemption state information reaches the preset number of times is adopted, and the phenomenon that the awakening response to the first voice information is triggered by the first equipment and the second equipment at the same time can be effectively avoided due to the fact that the first equipment and the second equipment compete for the preset number of rounds.

In the foregoing solution, the performing a wake-up response triggered by the preset wake-up word after the number of times of broadcasting the second preemption state information reaches a preset number of times includes:

if the number of times of broadcasting the second preemption state information by the first device reaches a preset number of times, sending a wake-up response request message to a cloud server;

Therefore, the cloud server determines whether the first device performs the wakeup response. Exemplarily, if the number of times that the first device broadcasts the second preemption state information reaches a preset number of times, sending a wakeup response request message to the cloud server; after the number of times of broadcasting the first preemption state information reaches a preset number of times, the second device sends a wakeup response request message to the cloud server; then, the server determines who to perform the wake-up response according to a preset rule, such as a random allocation principle.

In some embodiments, the method further comprises:

if the network device intercepts a wakeup response request message sent by a first device for a first voice message and a wakeup response request message sent by a second device for the first voice message, a target device is determined from the first device and the second device according to a preset rule such as a random distribution principle or a near distribution principle, and the wakeup response request of the target device is released.

For example, the network device may be a router.

Therefore, when a plurality of devices request to wake up the same voice message, the only device is determined locally to send the wake up request to the server, so that only one device sending the wake up request to the server through the router is required for the voice message sent by the user at the same time, the process of local identification and judgment is realized, and the calculation load of the server is reduced.

Example two

Fig. 2 is a flowchart illustrating a wake-up control method according to an exemplary embodiment, where the wake-up control method is applied to a cloud server, as shown in fig. 2. The wake-up control method includes the following steps.

In step S21, a wake-up response request message sent by the first device is received, where the wake-up response request message is: and when the detected first voice information contains a preset awakening word, the first equipment does not monitor the first preemption state information sent by the second equipment, and broadcasts the second preemption state information and then sends the second preemption state information.

In step S22, a wakeup grant response message is returned to the first device based on the wakeup response request message, where the wakeup grant response message is used for the first device to perform a wakeup response triggered by the preset wakeup word.

Therefore, only one device which sends the awakening request to the server in the first device and the second device is used for the first language information, so that the calculation burden of the server side can be reduced, the server side can respond to the awakening request quickly, and the response speed is improved.

In some embodiments, said returning an agreement wakeup response message to said first device based on said wakeup response request message comprises:

Therefore, the cloud server determines whether the first device performs the wakeup response.

In some embodiments, the method further comprises:

According to the technical scheme of the embodiment of the disclosure, the first device sends the awakening response request message to the cloud server after broadcasting the second preemption state information; if the second preemption state information is not broadcast, a wake-up response request message is not sent to the cloud server; in addition, compared with a response mode that the first device and the second device both send the awakening requests to the cloud server to request the cloud server to determine who awakens the response, the problem that transmission delay is too long due to the fact that multiple devices send the awakening requests to the cloud server can be avoided, and response speed of the preset awakening words is improved.

EXAMPLE III

Fig. 3 is a schematic diagram illustrating how to screen the voice assistant device a for a wake-up qualification twice according to an exemplary embodiment, where, as shown in fig. 3, the voice assistant device a, the voice assistant device B, the voice assistant device C, and the voice assistant device D are in the same smart home system, and the wake-up words corresponding to the four voice assistant devices are the same. The user speaks a wakeup word, the monitoring durations T1B and T1D of the voice assistant device B and the voice assistant device D are relatively long, the monitoring durations T1A and T1C of the voice assistant device A and the voice assistant device C are equal and smaller than T1B and T1D, both the voice assistant device A and the voice assistant device C send preemption state information, the duration of sending the preemption state information by the voice assistant device A is T3A, the duration of sending the preemption state information by the voice assistant device C is T3C, and T3A is T3C, because the voice assistant device B and the voice assistant device D find that the voice assistant device A and the voice assistant device C have sent the preemption state information, the preemption state information is not sent based on the wakeup word any more, namely the contention wakeup qualification fails; the duration of the first round of competition of voice assistant device a and voice assistant device C, T4A and T4C, is equal, after the first round of competition is over, it is determined who won' T be won, and then the second round of competition is entered, in the second round of competition, voice assistant device a at T1A ₂ After the duration, finding that the preemption state information is not monitored, and then sending a preemption state message; while the listening duration of voice assistant device C in the second round of contention is at T1C ₂ Greater than T1A ₂ Therefore, since the voice assistant device C monitors that the voice assistant device a broadcasts the preemption state information, the voice assistant device a does not send the preemption state information based on the wakeup word any more, and finally, the voice assistant device a robs the wakeup qualification.

It should be noted that, through 1 round of contention, there may still be a plurality of voice assistant devices sending preemption state information, and optionally, after the voice assistant device obtaining the wakeup opportunity ends the duration corresponding to the round of contention, the voice assistant device starts from monitoring the preemption state and performs M (M > ═ 0) rounds of additional wakeup contention, so as to reduce the number of cases that the voice assistant devices are woken up. It should be noted that the duration corresponding to each round of competition can be shortened randomly or according to factors such as sound intensity.

Taking bluetooth broadcast as an example, the time interval of bluetooth broadcast ranges from 20ms to 10.24s, the interval difference is an integral multiple of 0.625ms, and the broadcast duration is about 1.25 ms. Generally, a user does not feel the 200ms delay, so that about ten rounds of awakening competition can be performed (on the premise of ensuring user experience), and the unique awakening terminal can be determined in a home environment or a working environment.

Therefore, the coordination work of awakening a plurality of devices can be completed locally and quickly, the devices which need to be awakened actually can be identified quickly, and in addition, compared with the situation that a plurality of devices send awakening requests to a server to request the server to determine who awakens to respond, the transmission delay can be reduced, and the signaling consumption can be saved.
