Specific embodiment
In being described below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etc
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specifically
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
As Fig. 1 shows a kind of structure diagram of automobile data recorder provided in an embodiment of the present invention, the driving recording
Instrument includes：It microphone 11, filter circuit 12, signal processing module 13, central processing unit 14,4G wireless communication modules 15 and raises one's voice
Device 16,
The central processing unit 14 connects the signal processing module 13, and the microphone 11 connects the filter circuit 12
Input terminal, the output terminal of the filter circuit 12 connects the input terminal of the signal processing module 13, the signal processing mould
The output terminal of block 13 connects the loud speaker 16, and the 4G wireless communication modules 15 connect the central processing unit 14.
In embodiments of the present invention, passive filtering and active filter circuit can be used in filter circuit 12, and the present invention is not to making
Filter circuit is specifically limited, and can be used active filter circuit, be could be used that passive filter circuit.The one of the present invention
In kind embodiment, the filter circuit 12 is active filter circuit, and the filter circuit 12 is used to gather the microphone 11
Voice signal be filtered, specifically, the filter circuit 12 is used for limiting speech band, will be beyond language it is dry
It disturbs and removes with noise.
Further, the signal processing module 13 includes signal conversion unit 131 and signal codec unit 132.Its
In, the signal conversion unit 131 is used to the filtered voice signal being converted into digital signal；The signal codec
Unit 132 is used to encode the digital signal by the coded format of setting.
Speech signal is analog signal, it is necessary to be converted to digital signal after the filtered processing of speech signal, the present invention one
In a embodiment, filtered speech signal is subjected to analog/digital conversion, by 3 steps：Sampling quantifies and encodes.Wherein,
Sampling also referred to as samples, exactly with a time upper discrete class value (being known as sampling value or sample) come instead of a continuous frequency band
Limited signal, typically according to Nyquist's theorem (sampling theorem), by the frequency of 2 times or more higher than sound highest frequency
(being typically 44.1KHz) samples sound.Quantify to be exactly that each sample for obtaining sampling is converted to number from analog quantity
Word amount represents, therefore also referred to as A/D conversions (analog/digital conversion), the sample after quantization are represented with several bits.
Coding is the storage and processing for the ease of computer, data compression is carried out to the data after sampling and quantization, to reduce data
Amount is organized data into according still further to certain defined form as file, so as to computer to it into line access and processing.In the world
Current is quantified and is encoded by PCM modulation systems, and sound can be become to one section of binary code, this section of code represents
Be exactly the sound on some time point intensity.There is this section of code, it is possible to it is stored, is played, the operations such as duplication.
Further, the central processing unit 14 is used to pass through the 4G wireless communication modules 15 by institute's predicate after coding
Sound signal is sent to Cloud Server 17, and passes through the 4G wireless communication modules 15 and receive the parsing of the Cloud Server 17 institute predicate
The feedback signal that sound signal obtains；Wherein, the feedback signal includes speech answering signal.
In embodiments of the present invention, after Cloud Server 17 receives speech signal, language identification and feature extraction are carried out, from
Feedback signal corresponding with current language feature is searched in the database of Cloud Server.
Further, the central processing unit 14 is used to according to the speech answering signal loud speaker 16 be controlled to carry out
Speech play.
Digital signal is first decoded by central processing unit, i.e., digital code is converted into corresponding level, forms rank
Then scalariform signal carries out low-pass filtering.According to signal and the theory of system, digital staircase shape signal is considered as preferable impulse
The convolution of sampled signal and rectangular pulse signal, then by convolution theorem, the frequency spectrum of digital signal is exactly impulse sampled signal
The product of frequency spectrum and rectangular pulse frequency spectrum (i.e. Sa functions).In this way, it is compensated by the use of the inverse of Sa functions as spectral characteristic, by number
Signal can revert to sampled signal.By sampling thheorem, the frequency spectrum of sampled signal was just simulated originally through ideal low-pass filter
The frequency spectrum of signal.Obtained analog signal is finally subjected to speech play after loud speaker amplifies.
Further, the feedback signal further includes open command signal and cut-off command；
The central processing unit 14 is used to open the driving recording of the automobile data recorder according to the open command signal
Function and the driving record function that the automobile data recorder is closed according to the cut-off command.
The structure diagram of another automobile data recorder provided in an embodiment of the present invention as shown in Figure 2, the driving note
Record instrument further includes：The display module 21 being connected with the central processing unit 14；The feedback signal further includes navigation path planning
Command signal；
The central processing unit 14 is used for according to the navigation path planning command signal planning travelling line, and passes through institute
Display module 21 is stated to be shown.For example, after user language input " navigation ", Cloud Server receives the speech signal of user
Afterwards, speech recognition is carried out, for the signal of feedback " opening navigation " to central processing unit, central processing unit receives feedback after identifying successfully
Automobile data recorder is controlled to open navigation feature after signal, and controlling loudspeaker plays " unlatching is navigated successfully, please input destination ".
After user language input " destination ", Cloud Server feeds back a navigation path planning command signal, centre after identifying successfully
Device is managed according to the navigation path planning command signal planning travelling line, and passes through the display module and is shown, finally
Controlling loudspeaker plays " starting to navigate ".
It is described according to the speech answering signal loud speaker progress speech play to be controlled to be pushed away including playing ambient services
Recommend information.For example, user speech input " around having what milk tea shop ", after Cloud Server parses user voice signal, feedback letter
Number to central processing unit, central processing unit carries out net by look-up command of the 4G wireless communication modules in the voice signal
Network is searched, after central processing unit receives the ambient services recommendation information searched and obtained by the 4G wireless communication modules, control
It makes the display module and shows that the ambient services recommendation information and/or the control loud speaker play the ambient services and recommend
Information.
It is described according to the speech answering signal loud speaker progress speech play to be controlled to be carried including playing short message input
Show voice.For example, when user needs to input short message, phonetic entry " sends an SMS to so-and-so ", and Cloud Server parsing user is defeated
The voice entered feeds back the signal of " sending an SMS to so-and-so " to central processing unit, and central processing unit is opened short according to feedback signal
Believe sending function, and controlling loudspeaker plays " please input short message content ", after user speech input " short message content ", is sent to institute
State Cloud Server.
