Detailed description of the invention
Fig. 1 is the flow chart of the location-based control method of ordering of embodiment one.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Embodiment one
As shown in Figure 1, present embodiments providing a kind of location-based control method of ordering, comprising the following steps:
S1: the acoustic information of active user is obtained by sound collection equipment；The sound collection equipment is highly preferred,
Annular microphone array is used to acquire the acoustic information of active user；This step is primarily to get the sound of corresponding user
Message breath, this is also the basis of following all steps.It can be with highly efficient accurate acquisition round table surrounding by annular microphone
Acoustic information, the sound source information got is more clear, then the later period carry out voiced translation also it will be made more accurate.It should
Annular microphone is generally positioned on dining table, is directed to the microphone number that different dining tables is provided with different quantity, such as needle
For table for four, the quantity that microphone is possessed in annular microphone is four, is directed to six people's tables, possesses wheat in annular microphone
The quantity of gram wind is six, is directed to ten people's tables, and the quantity that microphone is possessed in annular microphone is ten；Had in this way
When gymnastics is made, can set each seat has a corresponding microphone.Other than above-mentioned such mode, it can also set
The microphone of fixed quantity is set, such as whether a few people's tables, possessing the quantity of microphone in annular microphone is six；Because
It only needs to complete to position by microphone in this process, without making everyone that can distribute to obtain a wheat
Gram wind, but, when being configured, that seat for possessing recording permission must have the corresponding microphone of distribution,
In order to preferably carry out information reception.
Additionally provide another embodiment in the present embodiment to carry out the wake-up of the control method, general wake-up
Mode can directly realize the switch of speech recognition system by power button, it is this be it is the most original, it is also not smart enough；
It can be selected in an alternative way as one kind in the present embodiment, and speech recognition system can also be arranged and be in normal
The state opened can only compare consuming electricity in this way, and be readily formed many unnecessary " instructions of ordering ", but its
A kind of mode be can be used as to be implemented, be only not belonging to be focused on the highly preferred mode of description in the present invention.
In the present embodiment most preferably, being that can carry out speech recognition system by the way of keyword wake-up
It wakes up, for example be set as " beginning of ordering " or " starting to order dishes " for keyword is waken up, when sound collection equipment collects in this way
Information when, then by the speech recognition system being in the standby state wake up to work, thus realize really from
Dynamicization processing.So that more smooth that can be carried out of ordering.Due to being not that owner can control the progress of meeting,
So need to be arranged one or more user to plan as a whole, a user is set most preferably to plan as a whole, because
Generally will not be especially more for the number of ordering, so it is proper be managed collectively only to need a user.By this user
Voiceprint be stored in advance in the server, the default wake-up word that only he says just has the function of starting.So-called sound
Line (Voiceprint) is the sound wave spectrum for the carrying verbal information that electricity consumption acoustic instrument is shown.Modern scientific research shows sound
Line not only has specificity, but also has the characteristics of relative stability.After adult, the sound of people can keep it is long-term relatively it is stable not
Become.It is demonstrated experimentally that no matter talker is deliberately to imitate other people sound and the tone, or whisper in sb.'s ear is softly talked, even if imitating only
Wonderful only Xiao, vocal print be not but identical always.So using this identification method of vocal print, more efficient is identified.
When the default wake-up word received, whether judgement voiceprint corresponding with default wake-up word is stored in server
In, if it is, starting sound collection equipment.It here, can be according to the habit of user when carrying out the default setting for waking up word
Be used to be configured, for example, it is common can be set " meeting starts ", such routinely words and phrases, corresponding restaurant can also be according to
According to the corporate culture of oneself, different wake-up words is set.For example " grandmother, I comes " can be set in this way in the wake-up word of outer husband's family
More individual character allow the system to have higher user's stickiness more for the wake-up mode of characteristic.So that single
System can different mode discrimination with higher in this way, also easily facilitate different enterprises have it is more personalized
Customization.
When carrying out waking up word setting, following manner can be set to, " ask everybody peace and quiet, preparation starts to order dishes."
When such setting, has higher anti-interference.Since when user carries out a dining room, at this time friend
Between can talk, sometimes can accidentally trigger speech recognition system, will result in certain starting fault in this way, can be from one
Determine to reduce user in degree to the trust of system stability.Therefore relatively long language is set, it can be made to wake up difficulty
It increases.More importantly when finishing " it is quiet to ask everybody ", it can be by information as detection ambient noise come really
Recognize, if be the clearly instruction of presider's sending of ordering, if after finishing, ambient noise is substantially reduced, then explanation is certain
Being will be formally into the mode of ordering, at this point, starting speech recognition system.After start-up, the speech recognition system, can also be into
Whether one step issues inquiry, ordered and started with confirmation, when the information is affirmative acknowledgement (ACK), then starting completely.
S2: use auditory localization technology with location sound information position；The auditory localization technology is based on time delay
The algorithm of estimation or the algorithm based on High-Resolution Spectral Estimation or the algorithm based on rarefaction representation, and the positioning step has
Body are as follows: after using auditory localization technological orientation sound position, close in addition to the wheat nearest with acoustic information position
Remaining microphone outside gram wind.When navigating to specific position, the microphone in face of it is most preferably only opened, and is incited somebody to action
Remaining microphone is closed, and is capable of the acoustic information of more efficiently acquisition current speaker in this way, and masks a part of theory
Words person's speaks in a low voice, and sound will not be caused to obtain in a kind of state that comparison is chaotic because many places sound source is generated.Because if
When talker is not one, and open simultaneously has multiple microphones at this time, then can not just judge their come
Source strength is weak, and can only open the wheat in face of speaker by all typings of all acoustic informations, so that certain confusion can be generated
If gram wind, whether can need to record corresponding information by sound intensity, audio direction etc. to position, and judge be
It is no to carry out recording replacement etc..
It is that the algorithm core based on TDE is accurate estimation to propagation delay to the auditory localization technology, general logical
It crosses and cross correlation process is done between signal microphone obtains.Sound source position information is further obtained, can be asked by being simply delayed
It is calculated with geometry or directly carries out the methods of controlled power response search using cross correlation results.Such algorithm is real
Existing relatively easy, operand is small, convenient for processing in real time, therefore in practice with most wide.
Time Delay Estimation Algorithms based on broad sense cross-correlation function introduce a weighting function, carry out to cross-spectral density
Adjustment, to optimize the performance of time delay estimation.According to the difference of weighting function, there are many different changes for broad sense cross-correlation function
Shape uses broad sense cross-correlation-phse conversion method (Generalized Cross Correlation in the present embodiment
PHAse Transformation, GCC-PHAT).GCC-PHAT method itself has certain antinoise and anti-reverberation ability,
But when signal-to-noise ratio reduces and reverberation enhances, which sharply declines.
Discovery microphone is practiced to the more big then reception to microphone of the maximum value of GCC-PHAT function by long-time
Signal is more reliable, that is, received signal quality is higher.Broad sense cross-correlation function Time Delay Estimation Algorithms are according to two Mike's wind
Number cross-correlation function peak value carry out estimation time delay value.In sonic location system, what each array element of microphone array received
Echo signal both is from the same sound source.Therefore, there is stronger correlation between each channel signal.Ideally, lead to
Cross the correlation function calculated between every two paths of signals, so that it may determine the time delay between two microphone observation signals.To complete
At the positioning of sound source.
SRP-PHAT (Steered Response Power-Phase Transform) based on phse conversion weight can
Control the auditory localization algorithm of responding power.Although there are many sound localization method based on microphone array, phse conversion adds
The controllable responding power SRP-PHAT auditory localization algorithm of power has stronger robustness, it can be achieved that true environment in reverberant ambiance
In auditory localization, therefore the algorithm can also be used as one of the present embodiment embodiment to be implemented.SRP-PHAT
There is no particular requirement to the formation of microphone, therefore be also applied for distributive array, therefore works as and be laid in based on distributive array
Positioning system, the algorithm can be used.
The basic principle of SRP-PHAT algorithm is to calculate all microphones to the phase for receiving signal in imaginary sound source position
The sum of the broad sense cross-correlation GCC-PHAT function of weighting is converted, finding in entire sound source space makes the maximum point of SRP value be sound
Source position estimation.SRP-PHAT has stronger robustness to reverberation, but in low signal-to-noise ratio SNR (Signal-to-
NoiseRatio) its positioning performance is poor in environment.It is above-mentioned it is several be specific auditory localization technology, but its be only wherein
Three kinds, when specific information collection, which is not limited to above-mentioned three kinds, and user can be according to the actual situation
To be designed.
S3: judging whether the acoustic information position stores in the server, if so, thening follow the steps S4；This
One step is primarily to filter out the user for having permission of ordering dishes, and when all users are when speaking, only selects therein
Possess permission of ordering dishes to completing corresponding order.
After navigating to the position of sound source, begin to obtain the user for possessing permission from backstage.Do not have in sound source position
Before change, the sound result identified can all correspond to this position.Because the present embodiment is by position to determine whether note
The acoustic information of the speaker is recorded, so corresponding position will be distributed before most starting to carry out meeting, such as one
Before a annular point dining table, there are 8 seats, number is 1,2,3,4,5,6,7 and 8 respectively, and stipulated that only No. 1 sound is believed
Breath can be recorded and record, and the sound of other number cannot, it is this when, general to send out when ordering food
The user of this dinner party sits on No. 1 position, then starts to order food operation.Or when being configured, setting two
A seat makes it possess permission of ordering, and for specific setting means in the present embodiment without limiting, dining room can be according to certainly
Oneself actual demand is set, and different settings is carried out for different seats in a restaurant, so can open when designing
This setting is put, so that the owned permission in each dining room goes to modify.
When thering are multiple users to possess to order permission, the problem of there is also change in location, in order to enable it possesses
Higher the degree of automation, the present embodiment additionally provide such mode to be implemented.Where the acoustic information got
When position change, then return step S2 is to relocate acoustic information；It is again right after the direction of voice changes
The direction of voice is positioned, and step S2 is returned to, and reacquires the information of sound source position and corresponding people.If it is original speech
People piped down, whether finish, if it has not ended, talking after waiting for if needing to judge entirely to order
People, then step S3 starts.Finish if ordered, whether terminate, order and finish just to stop recording if inquiry being prompted to order, quasi-
Standby confirmation of ordering.Because the orientation of sound constantly changes, if being merely able to record one during entirely ordering
The information of user, then it is very imperfect to order；And when number is more, all information requires one
User if confirming, can aggravate the task of the user, and the process that entirely to have dinner is not special happiness.So
During entirely ordering, in addition to that can recognize current sound, when the bearing change of sound, which can also
With the situation according to reality come positioning again to complete the acquisition to acoustic information.
S4: the menu name information in acoustic information is extracted, and generates instruction of ordering.This step is primarily to extraction sound
The menu name information for including in message breath, but the confirmation of this menu name information is not merely to recognize wherein to possess dish
It is just directly extracted after product name information, but need further to judge；Only when this vegetable is selected in confirmation
It just extracts and generates instruction of ordering.For example, when have " how is fish-flavoured shredded pork? " it is not certainly when such information
It needs to extract, just be extracted when only occurring declarative sentence, " I wants fish-flavoured shredded pork." so also being needed in this process to obtaining
The acoustic information got carries out semantics recognition, only confirms that the sentence is just to order food operation when ordering food again.
S5: when receive order END instruction when, all menu name information for getting are read by loudspeaker.For
Enable information on services during entirely ordering more accurate, receive order END instruction when, pass through
Loudspeaker is read out the titles of all vegetables obtained.Because it is different from meeting to order, when meeting adjourned,
The generation of pause is had, and this process of ordering is different, does not have pause after ordering, also will do it friendship between friend
It talks, so needing to close the system using direct mode, to prevent stop to unnecessary vegetable.What is closed
When, and can there is physics to close mode and software closing mode, it is to click directly on power switch that physics, which closes mode,；And software
Closing mode is closed by saying word as " end of ordering "；It is preferred in this embodiment to be closed using software
The mode closed.After receiving such instruction, the catalogue of ordering that can be sent completely is confirmed whether it is institute to current user
These vegetables having.
S6: the validation of information instruction that active user issues is received；After user hears out all vegetables, if accurate nothing
It misses, then directly reply does not need modification or information as no mistake of ordering is given to system and goes to be further confirmed that.
And thering is a vegetable to be not intended to the either not no point of user suddenly when having modification, such as among user, then it is said
Spoken instructions as " should not fish-flavoured shredded pork " are given to system and go further to be judged out.
S7: instructing according to validation of information to judge whether to need to modify corresponding instruction of ordering, if it is, modification corresponds to
Instruction of ordering；System needs further to analyze the content information for including in the words after receiving such instruction, than
If " should not fish-flavoured shredded pork " be to confirm this entry of the fish-flavoured shredded pork in menu directory to deleting by semantic analysis, and when out
When language as existing " increasing eggplant to stew ", need to realize by increasing vegetable by semantic analysis confirmation, this
When then increase corresponding dish information in menu directory.
S8: final instruction of ordering is sent to server end to complete to order.Final instruction of ordering refer to by
All dish informations of user's confirmation, when getting such final dish information, it is only necessary to by these information
It is sent to background server and goes confirmation, at this time background server is sent to rear kitchen and goes to prepare for a meal.It thus can be real
It now entirely orders operation.Due to ordering, operation has been completed, and is closed sound collection equipment so at this time needing to control or is made
It obtains sound collection equipment in a dormant state, is ordered food so that the system can not receive to order dishes to instruct, to prevent
User is overdue.
It is at this time still corresponding to possess the power of ordering when the user of the dining table needs to add dish during having dinner
The user of limit goes to wake up the sound collection equipment.Wake-up word at this time is preferably different with wake-up word at first
Sample can set it to " needing to add dish ".Be conducive in this way one completion have dinner during judgement so that being tied
It can be more convenient when calculation.
