Moreover, after the speech content of the user is converted into the audio signal by the sound pickup 130, the audio signal can be directly transmitted to the mobile intelligent terminal through the bluetooth module 150, so as to realize the bluetooth communication function. The user just need not break away from the steering wheel with the hand and control mobile intelligent terminal in the driving process to and can keep the sight on the vehicle advancing direction all the time, and then improve driving safety. The vehicle-mounted multi-microphone mobile phone interaction recorder 100 can be matched with most mobile intelligent terminals and the vehicle machine 300, and is good in compatibility effect.

Referring to fig. 1, the pickup 130 may optionally include at least two first microphones respectively disposed at two opposite sides of the recorder body 110. Through arranging two first microphones on different positions, can realize the effect of microphone array, promptly, utilize two first microphones to receive the difference between the phase place of audio frequency sound wave, filter the sound wave of gathering, can reject partial environment background sound effectively, and then improve the accuracy that follow-up speech recognition module 140 discerned the audio information that adapter 130 gathered to and the audio frequency definition when the bluetooth is conversed.

Optionally, the voice recognition module 140, the bluetooth module 150, and the FM transmitter 160 are integrated on the main control board 120. The operation convenience and the assembly efficiency when the main control panel 120 after integration is assembled to the recorder body 110 can be improved.

Further, the functional module also includes a speaker 170. The speaker 170 is used for broadcasting the instruction execution result or the incoming call information of the mobile phone, so that the user can conveniently confirm the completion condition of the previous voice interaction instruction, judge whether the next voice interaction instruction needs to be sent or not, and judge whether the call needs to be answered or not. For example, when the user speaks a voice interaction instruction content such as "play next song", the vehicle-mounted multi-microphone mobile phone interaction recorder 100 collects, identifies and converts the voice interaction content into a control instruction, and then transmits the instruction to the mobile intelligent terminal through the bluetooth module 150 to control the mobile intelligent terminal to stop the song being played and switch to the next song, and then the speaker 170 broadcasts audio information such as "switched song" to inform the user of the instruction execution result, and if the user is still unsatisfied with the switched song, the vehicle-mounted multi-microphone mobile phone interaction recorder 100 continues to execute the above process. Or, when the mobile intelligent terminal has a call coming in to be answered, the speaker 170 will broadcast "a certain call, whether answering" so as to inform the user in time; if the user decides to reject the incoming call and speaks a call such as "hang up", the in-vehicle multi-microphone handset interaction recorder 100 controls the mobile intelligent terminal to hang up the incoming call, and the speaker 170 broadcasts "hang up call" to inform the user of the instruction execution result.

Further, the functional module further includes a camera module 180, at least two speakers 170 are provided, and the at least two speakers 170 are respectively provided at the left and right sides of the camera module 180. Without loss of generality, the tachograph is typically mounted in the central symmetry plane of the vehicle and in the area close to the front windscreen, while the camera module 180 comprises a camera for taking images of the environment in front of the vehicle. By the two speakers 170 respectively arranged at the left side and the right side of the camera module 180, the user can clearly and accurately receive the audio information broadcasted by the speakers 170 no matter where the user is in the vehicle.

Optionally, the voice recognition module 140 further includes an echo cancellation unit electrically connected to both the speaker 170 and the car machine 300, and the functional module further includes a second microphone 250 electrically connected to both the voice recognition unit and the echo cancellation unit. The second microphone 250 is also used for acquiring the speech content of the user, and combines with the speech recognition unit to recognize the speech content and convert the speech content into a control instruction, so as to directly control the vehicle-mounted multi-microphone mobile phone interaction recorder 100 to perform related operations, such as turning on or off the dongle function, starting the camera module 180 to take a snapshot, uploading a video, and the like. In addition, the second microphone 250 operates separately from the sound pickup 130 and also serves to perform echo cancellation on an audio signal played by the speaker 170 or the car stereo in combination with an echo cancellation unit. The Echo Cancellation unit can filter out interference of radio station and multimedia music emitted from the speaker 170 or the car audio itself by using AEC (Automatic Echo Cancellation) technology. Since FM radio or multimedia music is played by the car stereo, these sounds are also recorded by the microphone 130 and the second microphone 250, and are ambient noise during speech recognition with respect to the user's speech content. It should be noted that, in the AEC technique, by acquiring the audio signal sent by the main control board 120 to the speaker 170 or the car 300 to the car audio and comparing the audio signal with the audio signal recorded by the second microphone 250, the echo cancellation unit can cancel the audio signal played by the speaker 170 or the car audio in the recorded audio signal, thereby improving the accuracy and the success rate of the voice recognition.

Further, the voice recognition module 140 further includes a noise filtering unit electrically connected to both the voice recognition unit and the sound pickup 130, and the audio information collected by the sound pickup 130 is processed by the noise filtering unit and then transmitted to the voice recognition unit. The noise filtering unit is provided with a general noise filtering algorithm, and can filter out wind noise and tire noise which are specific under the vehicle running environment.

Further, the functional module further comprises a MIC interface 190 and a codec 210 electrically connected between the microphone 130 and the speech recognition module 140, and the codec 210 is electrically connected to the MIC interface 190. The audio information collected by the sound pickup 130 is sent to a Codec 210(Codec) through the MIC interface 190, and then the Codec 210 converts the input audio into a PCM (Pulse Code Modulation) encoded audio stream after D/a conversion, so as to achieve the highest fidelity level.

The codec 210 does not have a Voice recognition capability, and therefore, the Voice recognition function is completed through a professional Voice recognition software VUI (Voice User Interface) running in an AP (Application processor) on the main control board 120. Due to the computational power limitation of the AP, the VUI speech recognition technology requires higher efficiency and better resource consumption, and is mainly based on DP (Dynamic Programming) algorithm for pattern recognition. The DP algorithm is based on an unknown input model and a reference model. In order to calculate the difference between the unknown input model and the reference model, the distortion on the time axis has to be shifted. The best correspondence between the two models is the minimum cumulative value that can be efficiently calculated using the DP algorithm to recognize various commands such as playing music, increasing or decreasing volume, waking up a cell phone voice assistant, answering a call, and rejecting the call. In this embodiment, the fixed voice command includes: the small mirror is good, the volume is increased, the volume is reduced, the previous phone is broadcasted, the next phone is broadcasted, the music is paused, the phone is answered, the phone is refused, and the phone is hung up, so that the direct recognition can be obtained on the AP. In addition, after the interactive recorder with the multi-microphone mobile phone is turned on, the FM transmitter 160 is turned on by the FM transmitting application of the AP in the previously saved state, and is set to the corresponding frequency.

Further, the functional module further includes a SIM card socket 220 for loading a SIM card to communicate with the mobile network; the audio information collected by the sound pickup 130 and the second microphone 250 is transmitted to the cloud server 400 after establishing communication with the mobile network through the SIM card. By utilizing the powerful computing and analyzing capability of the cloud server 400, the audio information collected by the sound pickup 130 and the second microphone 250 can be selectively transmitted to the cloud server 400 for voice recognition and converted into an instruction, and then the instruction is transmitted to the vehicle-mounted multi-microphone mobile phone interaction recorder 100 to control the mobile intelligent terminal to execute the instruction according to the instruction. By utilizing the more powerful voice cloud analysis function of the cloud server 400, the efficiency of voice recognition can be improved, and the requirement on the calculation analysis performance of the AP of the vehicle-mounted multi-microphone mobile phone interaction recorder 100 can be reduced.

Optionally, bluetooth module 150 employs the bluetooth 4.0 protocol. The bluetooth 4.0 protocol has the advantages of faster transmission speed and low power consumption, and is favorable for bluetooth communication connection between the bluetooth module 150 and the mobile intelligent terminal. However, the present design is not limited thereto, and in other embodiments, the bluetooth module 150 may also adopt a bluetooth 4.2 protocol or a bluetooth 5.0 protocol.

Further, the functional module further includes an emergency call button 230 exposed on the recorder body 110, and the emergency call button 230 is electrically connected to the SIM card socket 220. When the vehicle-mounted multi-microphone mobile phone interaction recorder 100 is in an on state, and the emergency call key 230(SOS key) is pressed for 2 seconds, the SIM card automatically dials a preset telephone number, such as an emergency contact telephone or a road rescue telephone or 110 or 120, so that the user can quickly respond to an emergency. For example, when a vehicle rollover accident occurs during driving, the user cannot escape from the cab by himself, but can get close to the emergency call button 230 on the recorder body 110, and can contact an emergency contact person in time to seek help.

Further, the functional modules further include a video display module 240, and the video display module 240 is disposed on a side of the recorder body 110 away from the camera. The video display module 240 may facilitate a user to preview image information captured by the camera module 180. in particular, a user generally has a higher interest in capturing image information captured by a camera used to capture the environment in front of the vehicle.

Optionally, the video display module 240 includes a display screen exposed on the recorder body 110, and the emergency call button 230 and the display screen are disposed on the same side of the recorder body 110. Without loss of generality, the display screen is arranged towards the driver, so that the driver can see the emergency call key 230 while seeing the display screen, the driver can conveniently recognize and touch the emergency call key 230, and convenience in using the emergency call key 230 in an emergency is improved.

In order to make it easier for the user to touch and press the emergency call key 230, optionally, the length direction of the emergency call key 230 is arranged in parallel with the width direction of the display screen, and the ratio of the length of the emergency call key 230 to the width of the display screen is set between 0.6 and 0.8. It should be noted that parallel refers to parallel and near parallel. The ratio of the length of the emergency call button 230 to the width of the display screen is too high to facilitate the miniaturization of the product size of the car-mounted multi-microphone handset interaction recorder 100, while too low to facilitate the user to touch the emergency call button 230, especially, the awareness of the user and the range of the movable limbs may be limited in an emergency situation.
