When equipment is in communication with each other, communication between any two equipment, which can be, directly to be carried out, and is also possible to by means of other equipment
Such as router progress.
As shown in Fig. 2, user generates voice signal by speaking, since sound can pass around in the form of a sound wave
It broadcasts, which can be received by multiple speech ciphering equipments, this is easy to cause the chaotic situation of multiple equipment response.For this purpose,
The present embodiment needle provides a kind of audio signal processing method, and this method can be applied to scene shown in Fig. 2.
Audio signal processing method provided in this embodiment is implemented by each of equipment group speech ciphering equipment, such as
Implemented simultaneously by each of speech ciphering equipment 210, speech ciphering equipment 220, speech ciphering equipment 230 equipment in Fig. 2.As shown in figure 3, should
Method includes the following steps S3100-S3300:
Step S3100 receives current voice signal.
For example, receiving current voice signal by the speech ciphering equipment 210 in Fig. 2.Current voice signal is, for example, to be used for
The wake-up voice signal of speech ciphering equipment is waken up, for example, the brief voice signal being made of several syllables, word or word, for calling out
Speech ciphering equipment wake up further to receive the phonetic order of user's sending.Current voice signal can also be the " tune that user issues
The voices such as big volume " " inquiry weather " " setting alarm clock ".Speech ciphering equipment 210 can for example receive voice letter by microphone
Number, and electrical signal form is converted from sound wave form by voice signal.
After being connected to voice signal, speech ciphering equipment executes following steps S3200:
Step S3200, decision whether voice responsive signal, obtain the result of decision.
For example, after speech ciphering equipment 210 receives current voice quotation marks in Fig. 2, to itself whether needing to believe the voice
Number response carry out decision, the result of decision responded.
In one example, step S3200 includes the following steps S3210-S3230:
Step S3210: speech ciphering equipment obtains the setting index that itself receives voice signal.
For example, the voice signal that the speech ciphering equipment 210 in Fig. 2 is received according to itself, determines that itself receives voice signal
Setting index.At the time of the setting index e.g. receives voice signal, in another example be the intensity for receiving voice signal,
It can also simultaneously include at the time of receive voice signal and receiving the intensity of voice signal.
When at the time of determining that speech ciphering equipment receives voice signal, it is same in advance can be carried out to multiple speech ciphering equipments the time
Step, then is recorded by each speech ciphering equipment at the time of itself receiving voice signal, with guarantee distinct device record when
Between be comparable.
When determining that speech ciphering equipment receives the intensity of voice signal, itself can be measured by speech ciphering equipment and receive voice
The indexs such as magnitude of sound, the loudness of signal, to characterize the intensity of voice signal.
Step S3220 obtains the setting index that other equipment in equipment group receive voice signal.
By taking the speech ciphering equipment in Fig. 2 as an example, the setting index for itself receiving voice signal has been got in speech ciphering equipment 210
In the case where, speech ciphering equipment 220,230 has also got the setting index that itself receives voice signal respectively according to same way.
At this moment, the setting index that itself receives voice signal can be sent to speech ciphering equipment 210 respectively by speech ciphering equipment 220,230, from
And make speech ciphering equipment 210 get speech ciphering equipment 220,230 reception voice signal setting index.
In one example, speech ciphering equipment 210 receives the setting index sent by other equipment in set period of time.It should
Set period of time is, for example, start of calculation at the time of receiving voice signal from speech ciphering equipment 210, in another example being received from speech ciphering equipment 210
The earliest moment of the setting index sent to other equipment starts.The setting of other equipment more than the set period of time is referred to
Mark, speech ciphering equipment 210 can be received no longer.By selecting suitable setting time segment length, it can be avoided reception other equipment
The process for setting index expends more time.
Speech ciphering equipment 220,230 can also obtain other equipment in equipment group by similar fashion and receive voice signal
Set index.
Step S3230: according to the setting index of the setting index of itself and other equipment, whether decision needs voice responsive
Signal.
For any appliance in equipment group, in the setting index situation for obtaining setting themselves index and other equipment
Under, decision itself whether can need voice responsive equipment accordingly.The embodiment of step S3230 is, for example:
(1) in step S3230, the intensity for itself receiving voice signal and other equipment are received language by speech ciphering equipment
The intensity of sound signal is compared, and when the intensity for itself being connected to voice signal is maximum one, is made and is needed voice responsive
The decision of signal.This mode is advantageously implemented in equipment group to be responded apart from the closer equipment of user.
(2) in step S3230, speech ciphering equipment will receive language with other equipment at the time of itself receiving voice signal
It is compared at the time of sound signal, when being earliest one at the time of itself receives voice signal, makes and need to respond language
The decision of sound signal.This mode is advantageously implemented equipment group and makes more quick response to voice signal.
(3) in step S3230, speech ciphering equipment is according to successive and intensity at the time of each equipment institute received voice signal
Size determines the overall target of the voice signal；Equipment itself received voice signal the optimal situation of overall target
Under, make the decision for needing voice responsive signal.This mode comprehensive consideration moment index and intensity index, are conducive to optimize
Response policy.In addition, overall target can more accurately be arrived relative to single index when determining that equipment is at a distance from user.?
In one example, the equipment nearest with user distance can be selected according to the overall target and is responded.According to related acoustics
Rule, it is assumed that the sound intensity of certain point is I, and the distance of the point to sound source is d, and the propagation time of sound is t, on the one hand, sound intensity I and
Distance d's square is inversely proportional, that is, I ∝ 1/d2, on the other hand, time t is directly proportional to distance d, that is, t ∝ d.Thus may be used
See, equipment can be reflected with user's distance d by the index of two aspects of sound intensity I and propagation time t.In order to measure distance d
Distance, can basisAnd t, and distribute and overall target is calculated with corresponding weight.It is with the speech ciphering equipment in Fig. 2
Example, it is assumed that the intensity value I that speech ciphering equipment 210,220,230 receives voice signal is successively 1,2,3, then corresponding
It is successively 1,0.71,0.57.Assuming that speech ciphering equipment 210,220 and 230 is successively 1,2,3 at the time of receiving voice signal, this
In approximate processing is carried out to propagation time of sound, it is believed that the equipment corresponding propagation time for receiving voice signal earliest is
0s, then the corresponding propagation time t of speech ciphering equipment 210,220,230 is followed successively by 0,1,2.For example successively with the weight of t
It is 0.8 and 0.2, then speech ciphering equipment 210,220 and 230 receives the overall target of voice signalSuccessively
It is 0.8,0.768,0.856, the overall target numerical value is smaller, and it is smaller at a distance from user to represent response apparatus, i.e. overall target
Its smaller index meaning of numerical value it is more excellent.Therefore the overall target of speech ciphering equipment 220 is optimal in this example, which makes accordingly needs
Want the decision of voice responsive signal.In this way, the equipment nearest apart from user can more accurately be selected.
The different embodiments of above-mentioned steps S3230 can be adapted for different equipment group response policies.For example, if
Response policy be selection equipment group in responded apart from the closer equipment of user, can choose above embodiment (1) or
Person (3), wherein the intensity or intensity and the weighted results at moment for receiving voice signal using equipment are as between equipment and user
The measurement index of distance.In another example if response policy is that the equipment that reaction speed is most fast in group is selected to be responded,
It can choose above embodiment (2), wherein as the weighing apparatus of the reaction speed of equipment at the time of receiving voice signal using equipment
Figureofmerit.
After the result of decision responded, speech ciphering equipment executes following steps S3300:
Step S3300 responds voice signal in the case where the result of decision is to need voice responsive signal.
Speech ciphering equipment has determined whether itself needs the result of decision of voice responsive signal by step S3200.In decision
As a result in the case where responding for needs, speech ciphering equipment can call the response of own hardware progress voice signal.
The mode that equipment responds voice signal is, for example, to issue response voice by loudspeaker, in another example being to pass through
Display device shows response figure or response text, in another example being to carry out response prompt by the variation and movement of indicator light.
Speech ciphering equipment is determined by step S3200 itself do not need voice responsive signal in the case where, not to current language
Sound signal is responded.
In audio signal processing method provided in this embodiment, any appliance in equipment group is receiving voice signal
Afterwards to itself whether needing to respond carry out decision, voice signal is responded according to the result of decision, avoids multiple equipment pair
In the problem that the response of same voice signal is chaotic, be conducive to the usage experience for improving user, speech ciphering equipment is made to become more intelligent
It is convenient.
In addition, in audio signal processing method provided in this embodiment, Response Decision of the speech ciphering equipment to voice signal
It is to be made by its own, the decision process of each equipment is relatively independent in group, so as to avoid the decision event of equipment component
Hinder the response performance to equipment group to affect greatly, so that audio signal processing method interaction is stablized in the present embodiment, it can
By property height.
In addition, the transmitting of voice signal setting index can carry out in a local network in the present embodiment, it is not necessarily to and server
Communication, interaction Caton phenomenon caused by can be avoided because of network delay.
A specific example of audio signal processing method is as follows in the present embodiment:
As shown in Fig. 2, speech ciphering equipment 210, speech ciphering equipment 220 and speech ciphering equipment 230 are speaker, three speakers are constituted
Equipment group is simultaneously playing same song.At this point, user wants the weather of inquiry tomorrow, and have issued that " how is weather tomorrow
The voice signal (in this case, all the voice signal is responded without three speakers) of sample ".For the voice signal,
Three speakers are performed both by step S3100-3300 described previously, wherein set index as receiving device and receive voice signal
At the time of.By decision, equipment 210, which determines, itself to be received earliest at the time of voice signal, therefore is rung to voice signal
It answers, starts the weather for broadcasting tomorrow.Equipment 220 and equipment 230 determine at the time of oneself receiving voice signal be not earliest, because
This does not respond voice signal, continues to play song.It can be seen that the audio signal processing method in the present embodiment can
Keep the Speech processing of equipment group more orderly, intelligent.
