[0002] With the rise of connected devices and the Internet, everything is connected, making it possible for two seemingly unrelated devices to be connected, so the interaction and management between devices has become particularly important. The interconnection between Bluetooth devices in the car has attracted the attention of technicians in this field. After the Bluetooth devices in the car are connected, it can provide convenience for users to view information, answer calls, send and receive voice messages, etc. while driving.

[0003] At present, the most widely used scenario for interconnection between Bluetooth devices in the car is the interconnection between the car computer and the mobile terminal. After the car computer and the mobile terminal are interconnected, the content on the mobile terminal interface can be projected onto the car computer display screen. For example, the navigation interface, music playback interface, etc. can be projected through the car computer. While the interconnection between the two brings convenience to users, there is also the disadvantage of recording delay. Specifically, after the car computer and the mobile terminal are interconnected, if the user records voice in the communication application of the mobile terminal, the voice message finally sent to the target object will be partially missing. The reason for this phenomenon is: after the car computer and the mobile terminal are interconnected, after the communication application of the mobile terminal receives the recording command, the mobile terminal defaults to recording by the car computer, and the car computer needs to switch to the microphone channel of the mobile terminal, which may cause some voice messages to be missing during the switching process. Summary of the invention

[0007] The vehicle computer sends the first recording segment to the mobile terminal;

[0008] After sending the first recording instruction, the mobile terminal waits for a second time to activate the second microphone of the local device to start recording, and then receives a recording end instruction to generate a second recording segment, wherein the second time is less than or equal to the first time;

[0022] Figure 3 is a structural block diagram of a Bluetooth device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1 , shows a step flow chart of a recording method according to an embodiment of the present invention.

[0025] The recording method of the embodiment of the present invention comprises the following steps:

[0026] Step 101: After receiving a first recording instruction sent by a mobile terminal, the vehicle computer turns on a first microphone of the vehicle computer to record a first recording segment of a first duration.

[0027] The first recording instruction is generated after the mobile terminal receives a recording instruction from a preset application.

[0028] The recording method provided in an embodiment of the present invention is applied to a Bluetooth interconnection system, which includes a vehicle computer and a mobile terminal. A Bluetooth connection is pre-established between the vehicle computer and the mobile terminal, and both the vehicle computer and the mobile terminal have a microphone recording function. A preset application is installed in the mobile terminal, and communication with others can be carried out through the installed preset application. The preset application can be an instant messaging application, such as WeChat, QQ, etc.

[0029] After the car computer and the mobile terminal establish a Bluetooth connection, the two devices can obtain microphone permissions from each other. Microphone permission is applied for when the car computer and the mobile terminal are connected for the first time. Once the microphone permission is granted, there is no need to repeat the microphone permission acquisition process after the software is subsequently opened.

[0030] After the preset application installed on the mobile terminal detects that the recording button is triggered, it generates a first recording instruction and sends the generated first recording instruction to the vehicle computer. The vehicle computer turns on the first microphone of the vehicle for recording. At the same time, the recording task is switched back to the mobile terminal from the vehicle computer. The mobile terminal turns on the second microphone for recording after waiting for a second time period, and the second time period is less than or equal to the first time period.

[0031] The process of switching the recording task from the vehicle computer to the mobile terminal takes a certain amount of time. During this period of time, the first microphone of the vehicle computer maintains the recording state and records the voice output by the user. The first duration is greater than or equal to the duration required for Bluetooth to switch audio I / O. The first duration can be flexibly set by technicians in this field. For example, the first duration can be set to 2 seconds, 3 seconds or 4 seconds, etc.

[0032] Step 102: The vehicle computer sends the first recording segment to the mobile terminal.

[0033] Step 103: After sending the first recording instruction, the mobile terminal waits for a second time period to activate the second microphone of the mobile terminal to start recording, and then receives a recording end instruction to generate a second recording segment.

[0034] The second duration is less than or equal to the first duration.

[0035] Step 104: The mobile terminal splices the first recording segment and the second recording segment according to a preset rule to generate a target recording segment.

[0036] The preset rules can be set by those skilled in the art according to actual needs, and there is no specific limitation on this in the embodiments of the present invention. For example: when the second duration is equal to the first duration, there may be no duplication between the first recording segment and the second recording segment. In this case, the first recording segment and the second recording segment can be directly spliced, and the first recording segment can be spliced ​​before the second recording segment; for another example: when the second duration is less than the first duration, there may be duplication between the first recording segment and the second recording segment. In this case, the first recording segment can be adaptively cropped before splicing, or the second recording segment can be adaptively cropped before splicing, etc.

[0037] The generated target recording segment contains all the voice content output by the user. The user does not need to wait for a certain period of time before outputting the voice, and the voice content output by the user will not be lost.

[0038] Step 105: The mobile terminal sends the target recording segment to the target object through a preset application.

[0039] The recording method provided by the embodiment of the present invention, on the one hand, because during the process of switching the recording task from the vehicle computer to the mobile terminal, the vehicle computer turns on the first microphone of the local computer for recording, and sends the first recording segment recorded by the first microphone to the second Bluetooth device for splicing. The target recording segment finally generated includes both the user's initial recording and the second recording segment recorded after the second microphone of the mobile terminal is turned on, which can ensure the comprehensiveness of the recorded voice message. On the other hand, this method of solving the recording delay is a process of data interaction and processing between the two Bluetooth devices of the vehicle computer and the mobile terminal, which is unaware of the user end and can improve the user experience.

[0040] In an optional embodiment, the mobile terminal splices the first recording segment and the second recording segment according to a preset rule. When generating a target recording segment, the mobile terminal splices the first recording segment and the second recording segment in sequence in chronological order to generate the target recording segment.

[0041] This method of directly splicing the first recording segment and the second recording segment takes less time.

[0042] In an optional embodiment, the mobile terminal splices the first recording segment and the second recording segment according to a preset rule to generate a target recording segment in the following manner:

[0043] The mobile terminal determines whether there is duplicate data at the end of the first recording segment and the beginning of the second recording segment; if there is duplicate data, deduplicates the end and the beginning; and sequentially splices the deduplicated first recording segment and the second recording segment to generate a target recording segment.

[0044] In the absence of duplicate data, the first recording segment and the second recording segment are directly concatenated in sequence to generate a target recording segment.

[0045] This optional method of generating a target recording segment does not contain duplicate data in the generated target recording segment, which can improve the consistency between the target recording segment and the user's output voice content.

[0046] In an optional embodiment, after the vehicle computer receives the first recording instruction sent by the mobile terminal, before the first microphone of the vehicle computer is turned on to record the first recording segment of the first duration, the following steps may be further performed:

[0047] The vehicle computer determines a first type of the mobile terminal; and the vehicle computer determines a first duration of a first audio segment to be recorded based on the first type.

[0048] The types of mobile terminals may include but are not limited to: mobile terminals of IOS system, mobile terminals of Android system, etc. Different types of mobile terminals have different corresponding response durations. If the response duration of the mobile terminal is longer, the first duration needs to be set to a larger value; conversely, if the response duration of the mobile terminal is shorter, the first duration needs to be set to a smaller value. The vehicle computer stores the correspondence between various types of mobile terminals and durations. After determining the first type of the mobile terminal, the duration corresponding to the first type can be determined based on the stored correspondence, and the duration corresponding to the first type is determined as the first duration.

[0049] In this optional manner, the first duration can be flexibly determined according to the type of the mobile terminal, and the determined first duration is closer to the actual duration required for Bluetooth switching audio I / O.

[0050] Based on the above description of the first duration, a brief example of the size of the second duration is provided.

[0051] Assuming that the response time of the mobile terminal is X seconds, it takes Y seconds to transmit the recording command between the mobile terminal and the vehicle computer, and the vehicle computer sends the recording command to the mobile terminal after the recording starts. The time it takes for the vehicle computer to receive the recording command and start recording is the response time X. Then, the time from the mobile terminal sending the recording command to the vehicle computer to the start of recording is greater than or equal to X+Y seconds, that is, the second time is greater than or equal to X+Y seconds. The first time must be longer than the second time to ensure that the recording is not missing.

[0052] For example: X is 2 seconds, Y is 0.5 seconds, then the second duration is greater than or equal to 2.5 seconds. It should be noted that 2 seconds, 0.5 seconds and 2.5 seconds are only examples. In the actual implementation process, it is also necessary to flexibly determine the response time of the mobile terminal and the time it takes for the vehicle and mobile terminal to transmit data. This embodiment of the present application does not impose specific restrictions on this.
