In step S60, when determining in voice command there is no wake-up signal, voice assistant equipment will not execute any
Operation.
The step of determining the intermediate equipment among multiple voice assistant equipment is discussed in detail referring to Fig. 3.
Fig. 3 is the flow chart for showing the intermediate equipment among the multiple voice assistant equipment of determination according to the embodiment.
In step s310, default intermediate equipment obtains between each voice assistant equipment and other voice assistant equipment
The average value of distance.Default intermediate equipment is any one voice assistant equipment in multiple voice assistant equipment.In other words,
Arbitrarily assume that any one voice assistant equipment is intermediate equipment.For example, multiple voice assistant equipment can determine in advance through consultation
If intermediate equipment.It should be understood that also obtaining the average value of the distance between other voice assistant equipment of default intermediate equipment.
It can be communicated between multiple voice assistant equipment, for example, when multiple voice assistant equipment are in consolidated network,
When by scanning surrounding speech assistant equipment based on location technology (such as, Ibeancon technology etc.), each voice assistant equipment
The distance between the voice assistant equipment and other voice assistant equipment can be automatically obtained.In particular, default intermediate equipment can

Between equipment.
Fig. 2 is returned, in step s 40, is received from the intermediate equipment and indicates have among the multiple voice assistant equipment
There is the response of the voice assistant equipment of highest priority.
Preferably, the priority of the multiple voice assistant equipment is determined as follows:
First, the priority of voice assistant equipment is determined according to the first characteristic of voice assistant equipment.Voice assistant equipment
The first characteristic be to issue the distance between position with wake-up signal.Voice assistant equipment and wake-up signal issue between position
Apart from smaller, the priority of voice assistant equipment is higher.In particular, in general, user wishes the voice assistant nearest away from oneself
Equipment executes voice command.Therefore, the distance between position is issued with wake-up signal to determine according to voice assistant equipment first
The priority of voice assistant equipment is (that is, voice assistant equipment issues smaller, the voice assistant in the distance between position with wake-up signal
The priority of equipment is higher).
Second, in the identical situation of the first characteristic, determine that voice assistant is set according to the second characteristic of voice assistant equipment
Standby priority, or the random relative priority determined between the identical voice assistant equipment of the first characteristic.Voice assistant is set
The second standby characteristic is at the time of sending wake request.More early, voice assistant at the time of voice assistant equipment sends wake request
The priority of equipment is higher.In particular, issuing identical feelings at a distance between position in voice assistant equipment and wake-up signal
Under condition, determine the priority of voice assistant equipment (that is, voice assistant at the time of sending wake request according to voice assistant equipment
More early at the time of equipment transmission wake request, the priority of voice assistant equipment is higher), or random determining voice assistant equipment
Between relative priority.
Third determines under the first characteristic and the identical situation of the second characteristic according to the third characteristic of voice assistant equipment
The priority of voice assistant equipment, or the random phase determined between the first characteristic and the identical voice assistant equipment of the second characteristic

Standby model and/or version.The quality for the network that voice assistant equipment is connected is better, and the priority of voice assistant equipment is got over
The model and/or version of height or voice assistant equipment are newer, and the priority of voice assistant equipment is higher.In particular, in language
At the time of sound assistant equipment issues identical the distance between position and voice assistant equipment transmission wake request with wake-up signal
In identical situation, the quality of the network connected according to voice assistant equipment or the model and/or version of voice assistant equipment
(that is, the quality for the network that voice assistant equipment is connected is better, voice assistant is set the original priority for determining voice assistant equipment
Standby priority is higher or the model and/or version of voice assistant equipment are newer, and the priority of voice assistant equipment is higher), or
Person determines the relative priority between voice assistant equipment at random.
4th, in the first characteristic, the second characteristic and the identical situation of third characteristic, according to the 4th of voice assistant equipment the
Characteristic determines the priority of voice assistant equipment, or random determining first characteristic, the second characteristic and the identical language of third characteristic
Relative priority between sound assistant's equipment.4th characteristic of voice assistant equipment is voice assistant equipment and the intermediate equipment
Distance.Voice assistant equipment is smaller at a distance from the intermediate equipment, and the priority of voice assistant equipment is higher.Specifically
It says, issues identical, voice assistant equipment at a distance between position with wake-up signal in voice assistant equipment and send wake request
The quality of network or the model of voice assistant equipment and/or version phase that moment is identical and voice assistant equipment is connected
With in the case where, according to voice assistant equipment determined at a distance from the intermediate equipment voice assistant equipment priority (that is,
Voice assistant equipment is smaller at a distance from the intermediate equipment, and the priority of voice assistant equipment is higher), or language is determined at random
Relative priority between sound assistant's equipment.The mode of the priority of the above-mentioned multiple voice assistant equipment of determination is only example, but
It is without being limited thereto.
Since voice assistant equipment is likely located at the different direction in space, each voice assistant equipment and wake-up signal are sent out
The distance between out position may be different, thus user is when issuing wake-up signal, and what each voice assistant equipment received calls out
The intensity of awake signal may be different, when each voice assistant equipment receives wake-up signal, are not immediately performed wake operation, and
It is to send intermediate equipment in the request for the carrying of respective voice assistant device-dependent message.As an example, wake-up signal
Intensity includes the decibel value of wake-up signal and/or the energy value of wake-up signal.
Optionally, when the voice assistant equipment is intermediate equipment, intermediate equipment has voice assistant for what is received
The request of device-dependent message is according to priority ranked up in descending order, and the voice assistant with highest priority is selected to set
It is standby to be used as target wake-up device.Target wake-up device refers to execute the voice assistant equipment of the voice command of user's sending.
It selects the voice assistant equipment with highest priority to avoid as target wake-up device to receive in each voice assistant equipment
The strong and weak relevant information of the wake-up signal arrived is (for example, the strength information of wake-up signal and/or the intensity letter based on wake-up signal
Breath calculates the voice assistant equipment obtained and wake-up signal issues the distance between position etc.) in identical situation, it can not determine
The problem of target wake-up device.
In step s 50, when the voice with highest priority that the voice assistant equipment is the response instruction helps
When hand equipment, wake-up signal is responded.
After voice assistant equipment receives response, voice assistant equipment by response facility information parameter and itself
Facility information parameter is matched, and when successful match, will be responded to wake-up signal (that is, the voice assistant equipment is called out
Wake up, into preset interactive voice state) and voice command is continued to execute, otherwise wake-up signal is not responded and put
It abandons and executes voice command.Only the voice assistant equipment (that is, target wake-up device) with highest priority carries out wake-up signal
Response, remaining voice assistant equipment do not respond the wake-up signal.
Optionally, it when the voice assistant equipment is the intermediate equipment, is received from the multiple voice assistant equipment
Wake request, and determine based on wake request the priority of the multiple voice assistant equipment, it will indicate that the multiple voice helps
The response of voice assistant equipment among hand equipment with highest priority is sent to the multiple voice assistant equipment.
