The three dimensions geometry of microphone array and sound source position is as shown in Figure 7.I-th pair microphone 1 and 2 is in x-axis
On, we are using the midpoint of line as reference origin 0, it is assumed that the time difference (path difference) of sound source to the two microphones is ti, wheat
The position vector m of gram wind 1 and 2i1、mi2Represent, s represents sound source position vector, then sound source s should meet vector equation：
∥mi1-s∥-∥mi2- s ∥=tic (3)
Wherein, τiIt is the path difference between two microphones, c is the velocity of sound under current media.It can be obtained by formula (3)
Know, the location of sound source is on a hyperboloid.
According to shown in Fig. 9, wherein sound source S position isIt is transformed into rectangular coordinate system and is：
mi1=(- | mi1-mi2|/2,0,0)
mi2=(| mi1-mi2|/2,0,0)
By s, mi1,mi2Substitution formula (3), both sides square can obtain：
cos2(θ)/(tic)2-sin2(θ)/(|mi1-mi2|(tic)2(the 4r of)=1/2) (4)
Because sound field is far field, i.e., when distance r is distant, 1/ (4r2) leveling off to zero, then this up-to-date style (5) can be approximated to be:
θ=cos-1(tic/|mi1-mi2|) (5)
As can be seen here, when the time delay between knowing microphone and apart from when, it is possible to approximately try to achieve θ angles.Work as sound source
For far field sound source when, the possible position of sound source can be represented with the conical surface at θ angles.As long as it is poor (path difference) to try to achieve relative time
ti, it is possible to approx try to achieve deflection of the sound source for two microphone line midpoints.It can just be obtained by two microphones
The possible position face of one sound source, pass through an array for including multiple microphones, it is possible to obtain multi-acoustical possible position
Face.The focus in these faces i.e. the position of sound source.But in actual conditions, due to error, it tends not to enough all meet at
A bit, be exactly sound source position as long as so find apart from the closest position in several faces, i.e. the position of user.

Step S106, obtain the voice signal of each voice collection device collection of voice collection device array；
Step S107, time delay value T of each voice signal relative to reference signal is calculated, according to corresponding T pairs of time delay value
Each voice signal compensates, so that each voice signal after compensation is identical；
Step S108, a wave beam is formed to all voice signal weighted sums, adjust the weights of weighted sum to obtain
The maximum wave beam of power output；
Step S109, the point corresponding to the maximum wave beam of search power output, the position of the point is customer location.
Auditory localization (customer location) based on beamforming algorithm, signal caused by sound source reach voice collection device battle array
Each voice collection device of row, due to raw path difference, the signal that each voice collection device receives can have difference, in order to
Corresponding signal can be obtained, the signal of each voice collection device is compensated, phase is changed into by the signal after compensation
Together.By forming a wave beam to voice signal weighted sum, maximum that of power output is tried to achieve by constantly adjusting weights
Individual wave beam, finally by the point searched for corresponding to prominent wave beam, the position of this point is exactly the position of sound, i.e. user
Position.

Previously selected code word identifies problem, and prompts to be determined as invasion simultaneously if not answering in limiting time or after restriction enquirement number
Open alarm.Now, microphone array starts to work asynchronously, and receives voice signal.
If intruder says sound, auditory localization is opened.So-called auditory localization, that is, pass through the letter of multiple microphone picks
Number and microphone array topological structure, you can it is determined that the position of one or more sound sources in space.In far field, voice is known
In other scene, after determining target sound source position, you can using beam forming technique, pick up target direction voice, suppress other sides
To interference, signal to noise ratio can be effectively lifted, reduces reverberation, lifts speech recognition accuracy.Voice knowledge is carried out to user's voice directions
Other algorithm enhancing, strengthens the phonetic recognization rate that speech recognition subsystem is directed to the direction.
Synchronous, if detecting, intruder says sound, can synchronously carry out the recording of sound bite, if follow-up judge
Intruder is invader, then the storage of intruder's sound clip is called for subsequent user and consulted into local storage.
After voice messaging input speech recognition engine, the voice messaging is identified engine, and means of identification is optional
Including：
Carry out determining whether to invade using the code word pairing word of user's training in advance in system.User is initially using
During the system, it is necessary to if opening intrusion detection, system can prompt the training that user carries out a customized code word pairing word,
A user-defined code word pairing word is obtained after training, speech recognition engine matches word and time of invader based on the code word
Answer and carry out template matches, if invader can not say user-defined code word pairing in limiting time or in restriction number
Word, then judge current intruder for invader.User can reset code word pairing word, when the training process of neologisms is with initial setting
Unanimously.
The code word problem answers being pre-filled with using user in system carry out determining whether to invade.User initially makes
With that, it is necessary to open intrusion detection, can select code word word preset in system during the system, the code word word is directed to this knowledge
Other engine has done the training of small sample amount, and speech recognition engine can identify various preset code word paired-word sounds.If swarm into
Person can not say the code word pairing word that user selectes in limiting time or in restriction number, then judge current intruder for invasion
Person.User can select code word problem answers again, consistent when process is with initial setting.Once judge current intruder for invasion
Person, alert.Prompting has cracker to swarm into, it is necessary to handle.
