Detailed Description
Before a multi-person voice conference begins, a conference system of each conference place needs to be tested, wherein the test of the sound receiving effect in the conference system is an important test item, and in the process of testing the sound receiving effect, the corresponding relation between each microphone and a sound card channel in the conference system needs to be determined. In order to improve the efficiency of constructing the correspondence between the microphones and the sound card channels, an embodiment of the present application provides a conference system, where the conference system includes at least two microphones, a sound card device including at least two sound card channels, and a device for constructing the correspondence between the microphones and the sound card channels. Exemplarily, the conference system 1 as shown in fig. 3 includes four microphones, i.e. a first microphone 111, a second microphone 112, a third microphone 113 and a fourth microphone 114, a sound card device 12, wherein the sound card device 12 provides four sound card channels, i.e. a first sound card channel 121, a second sound card channel 122, a third sound card channel 123 and a fourth sound card channel 124, and a microphone and sound card channel correspondence building means 13.
In this embodiment, the microphone is a receiver having a voice collecting function, and may be a microphone, a mobile phone, a bluetooth headset, an intelligent wearable device, and the like, and the microphone and the sound card device may be connected through wired or wireless communication, in this embodiment (based on the communication connection, the correspondence between the microphone and the sound card device cannot be directly determined). The microphone may also integrate other functions, such as the function of playing audio data, etc.
In the present embodiment, the sound card device 12 refers to a speech processor with a speech information processing function, wherein the sound card device may provide a plurality of sound card channels, and in order to ensure the processing quality of speech information, the sound card device is configured such that one sound card channel can only serve one microphone, that is, there is a unique corresponding relationship between the sound card channel and the microphone. It should be noted that the unique correspondence may be dynamically adjusted according to requirements, and the unique correspondence between the microphone and the sound card channel is still ensured after adjustment, so as to ensure the processing quality of the voice information collected in the conference.
In this embodiment, the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel is connected to the sound card device 12 to receive the test information collected by the sound card device 12. The device 13 for constructing a channel correspondence relationship between a microphone and a sound card includes a processor and a memory, where the processor may include one or more processing units, such as a system on a chip (SoC), a Central Processing Unit (CPU), a Microcontroller (MCU), a memory controller, and the like. The different processing units may be separate devices or may be integrated into one or more processors. For example, the processor may include a speech information processing engine for converting test information (speech information) into different forms of recognition information (text information, waveform information, etc.).
The memory may include one or more memory units, for example, may include a volatile memory (volatile memory), such as: dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), and the like; non-volatile memory (NVM) may also be included, such as: read-only memory (ROM), flash memory (flash memory), and the like. The different memory units may be separate devices or may be integrated or packaged into one or more processors and become a part of the processors. The memory is used for storing computer instructions, identification information, first mapping information related to the test information and the microphone, second mapping information corresponding to the test information and the identification information and the like for the processor to execute.
In some embodiments, the constructing apparatus 13 for the channel correspondence between the microphone and the sound card may be connected to a sound device to play the voice information through the sound device, and may also be connected to a display device to display text information, waveform information, and the like corresponding to the voice information through the display device.
In this embodiment, the constructing apparatus 13 for the correspondence between the microphone and the sound card channel may adopt the method shown in fig. 4 to construct the correspondence between the microphone and the sound card channel, which is specifically as follows:
s401, acquiring all identification information and first mapping information, wherein one identification information corresponds to one sound card channel, one identification information is acquired based on one test information, the first mapping information comprises a corresponding relation between a plurality of microphones and a plurality of test information, one microphone corresponds to one test information, and the different microphones correspond to different test information.
The tester inputs test information into each microphone, and for example, in the conference system shown in fig. 3, the tester needs to input test information into the first microphone 111, the second microphone 112, the third microphone 113, and the fourth microphone 114, respectively. The embodiment does not limit the sequence of the test information input to each microphone by the tester, and the tester inputs the test information to each microphone according to a certain sequence so as to ensure that the test information cannot be input repeatedly or input omission. Illustratively, the test information is input to each microphone in a clockwise order, a counterclockwise order, or a numbering order of the microphones, or the like.
In this embodiment, in order to distinguish different microphones, the tester inputs different test information to the different microphones, and in order to facilitate recording, the tester inputs only one test information to each microphone. That is, there is a unique correspondence between the test information and the microphone.
The unique corresponding relation between each microphone and the test information can be manually recorded, for example, on paper, so as to facilitate subsequent manual comparison, and in order to further improve the accuracy and efficiency of the subsequent process of constructing the channels between the microphones and the sound cards, the unique corresponding relation between each microphone and the test information can be stored in the constructing device 13 for the corresponding relation between the microphones and the sound cards, so as to obtain the first mapping information, and the automated relation constructing process can be completed through the constructing device. Illustratively, the tester inputs test information a at the first microphone 111, test information B at the second microphone 112, test information C at the third microphone 113, and test information D at the fourth microphone 114. Accordingly, the microphone and sound card channel correspondence constructing means 13 records the correspondence between the microphone and the test information, for example, in the form of a data pair, and the first mapping information includes "first microphone-test information a; second microphone-test information B; third microphone-test information C; fourth microphone-test information D ".
In one implementation, the first mapping information is preset mapping information, that is, before a tester performs a test, the first mapping information is already set and stored in the construction device 13 for correspondence between the microphones and the sound card channels, and when the tester performs the test, the tester directly inputs corresponding test information to each microphone according to the mapping information set in the first mapping information. Therefore, the tester does not need to set the test information during testing, and can directly utilize the test information in the first mapping information, so that the energy of the tester is effectively saved, and the efficiency of inputting the test information is improved.
In one implementation, the first mapping information is set by a tester, and the tester inputs the first mapping information into the construction apparatus 13 of the channel correspondence relationship between the microphone and the sound card. Therefore, the most appropriate test information can be set according to the real requirement during testing, so that the effectiveness and the accuracy of the test are improved.
In one implementation, the first mapping information is set by a tester, and the first mapping information is automatically determined by the construction apparatus 13 of the correspondence relationship between the microphone and the sound card channel. Illustratively, the constructing means 13 for microphone and sound card channel correspondence is connected with each microphone to receive the test information sent by each microphone, for example, if the constructing means 13 for microphone and sound card channel correspondence receives the test information a from the first microphone 111, the correspondence is established between the first microphone 111 and the test information a, and the test information a is recorded. Thus, the energy of the tester can be further saved, and the recording efficiency of the test information is improved.
In this embodiment, the test information is voice information, that is, the tester can directly speak out the password to the microphone, so that the tester can input the test information, and the input efficiency of the test information is improved.
As can be seen from the above, the test information corresponding to each microphone is different to distinguish each microphone. Specifically, the test information may have simple indicators, such as "a", "B", etc., which are commonly used identifiers and have general applicability, for example, the test information with the indicator "a" may correspond to the first microphone 111, and may also correspond to other microphones. In some embodiments, the indicator has a strong correspondence with the microphone, that is, the test information with the indicator can only be used for testing the microphone corresponding to the indicator, such as "northwest corner", "southeast corner", etc., and because the microphone is located at a position having a relative fixity in the testing process, the indicator has a strong correspondence with the microphone, and it is impossible to test the microphone located at the southeast corner with the test information with the indicator "northwest corner". Based on the strong correspondence between the indicator and the microphone, if the tester sets the test information in the test process, the tester can quickly determine the indicator corresponding to the currently tested microphone, thereby improving the efficiency of setting the test information. If the first mapping information is preset mapping information, the tester can quickly and accurately determine the testing information based on the strong correspondence between the indicator and the microphone.
After the tester inputs corresponding test information in all the microphones, the test information is collected into the sound card channels corresponding to the microphones, and then the test information output from each sound card channel is identified and processed by the constructing device 13 for corresponding relationship between the microphones and the sound card channels to obtain identification information, and the corresponding relationship between the microphones and the sound card channels is determined based on each identification information. In this embodiment, the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel may use the method shown in fig. 5 to obtain the identification information, which is as follows:
and S501, receiving all the test information sent by the tester.
In this embodiment, the constructing apparatus 13 of the corresponding relationship between the microphone and the sound card channel receives the test information through the sound card channel, and as can be seen from the above, the test information is the voice information, and the constructing apparatus 13 of the corresponding relationship between the microphone and the sound card channel receives the voice information through the sound card channel. Illustratively, the constructing apparatus 13 for microphone and sound card channel correspondence receives the test information E through the first sound card channel 121, receives the test information F through the second sound card channel 122, receives the test information G through the third sound card channel 123, and receives the test information H through the fourth sound card channel 124. The test information E, the test information F, the test information G, and the test information H in this example are consistent with the test information a, the test information B, the test information C, and the test information D, and in the current scenario, since it is not directly known which test information is received by the sound card channel, different letter codes are used for distinguishing.
S502, converting each piece of test information into corresponding identification information based on a preset identification mode.
In this embodiment, the identification manner refers to a manner for subsequently comparing the received test information with each piece of test information in the pre-stored first mapping information, and the preset identification manner refers to an identification manner set in the test process. Correspondingly, in order to satisfy different recognition modes, the constructing device 13 for the correspondence relationship between the microphone and the sound card channel converts each piece of test information into the recognition information corresponding to the recognition mode by using different speech information processing engines after receiving the test information, so as to satisfy the requirement of subsequently adopting the preset recognition mode and comparing the test information and the recognition information in the pre-stored first mapping information.
The identification mode may be audiometric identification, that is, a specific content to be identified is obtained from the test information in an audiometric mode, so as to compare the content with each test information in the pre-stored first mapping information. Based on this audiometric recognition, because the test information received by the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel is the voice information, the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel does not need to perform special processing on the received test information, and can directly use the test information as the recognition information.
The identification mode may be reading identification, that is, the specific content to be identified is obtained from the test information in a reading mode, so as to compare the content with each test information in the pre-stored first mapping information. Based on the reading and recognition manner, since the test information received by the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel is the voice information, the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel needs to convert the received test information into the text information first, so as to use the converted text information as the recognition information. The process of converting the test information into the text information by the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel may refer to the following flow:
s5021, acquiring a corresponding relation between voice and text;
and S5022, converting the voice information into corresponding text information based on the corresponding relation between the voice and the text.
The identification mode may be waveform identification, that is, the waveform is used as a specific content to be identified to be compared with each piece of test information in the pre-stored first mapping information. Based on the waveform recognition, since the test information received by the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel is the voice information, the constructing apparatus 13 for the correspondence relationship between the microphone and the sound card channel needs to convert the received test information into the waveform information first, so as to use the converted waveform information as the recognition information. Illustratively, the constructing apparatus 13 for the channel correspondence between the microphone and the sound card is provided with a speech information processing engine having a waveform collecting and recognizing function, and the engine can collect waveform information in the test information.
As can be seen from the manner in which the above-described construction apparatus 13 for the correspondence between the microphone and the sound card channel acquires the identification information, one identification information corresponds to one sound card channel. For example, the test information E corresponds to the identification information E, the test information F corresponds to the identification information F, the test information G corresponds to the identification information G, and the test information H corresponds to the identification information H. Accordingly, the identification information e corresponds to the first sound card channel 121, the identification information f corresponds to the second sound card channel 122, the identification information g corresponds to the third sound card channel 123, and the identification information h corresponds to the fourth sound card channel 124.
S402, constructing second mapping information, wherein the second mapping information comprises a second corresponding relation between each piece of identification information and the test information.
In this step, the test information refers to the test information sent by the tester, and also refers to the test information in the pre-stored first mapping information, that is, the above example test information a, test information B, test information C, and test information D, and the identification information indicates the test information converted by the speech recognition engine 13, that is, the above example identification information e, identification information f, identification information g, and identification information h. By comparing the test information a, the test information B, the test information C, the test information D with the identification information e, the identification information f, the identification information g, and the identification information h, the correspondence between the test information and the identification information can be determined.
Based on different preset identification modes, the specific identification process is also different, and the specific identification process is as follows:
if the preset recognition mode is audiometric recognition, the recognition information is test information (voice information), and the construction device 13 for the correspondence relationship between the microphone and the sound card channel can control the sound device to directly play the recognition information. In one implementation, the tester listens to the identification information to obtain specific content carried in the identification information, and compares the specific content with the test information to determine a corresponding relationship between the identification information and the test information. In one implementation, the device 13 for constructing a correspondence between a microphone and a sound card channel further includes a device acquisition having a sound recognition function and a semantic analysis function, and recognizes the played recognition information through the device, so as to obtain the specific content carried in the recognition information, and compare the specific content with the test information to determine the correspondence between the recognition information and the test information.
If the preset recognition mode is reading recognition, the recognition information is converted text information, and the construction device 13 for the correspondence between the microphone and the sound card channel can control the display to directly display the recognition information. In one implementation, a tester reads the identification information to obtain specific content carried in the identification information, and compares the specific content with the test information to determine a corresponding relationship between the identification information and the test information. In one implementation, the device 13 for constructing a correspondence between a microphone and a sound card channel further includes a device having text recognition and semantic analysis functions, and the device collects and recognizes the displayed recognition information, so as to obtain the specific content carried in the recognition information, and compares the specific content with the test information to determine the correspondence between the recognition information and the test information.
If the preset identification mode is waveform identification, the identification information is detected waveform information, and the construction device 13 for the correspondence relationship between the microphone and the sound card channel acquires waveform information corresponding to each piece of test information to use the acquired waveform information as a representative of the test information for subsequent comparison. The correspondence between the identification information and the test information is determined by comparing the waveform information of the detected identification information and the waveform information of the acquired test information.
In the process of establishing the corresponding relationship between the identification information and the test information, the corresponding relationship is established between the identification information and the test information which are consistent. And summarizing the constructed corresponding relation between all the identification information and the test information to obtain second mapping information. By way of example, through the above-mentioned construction process, second mapping information "identification information e — test information a" may be obtained; identification information f-test information B; identification information g-test information C; identification information h-test information D ".
In some embodiments, if the test information carries an indicator having a strong correspondence with the microphone, accordingly, the converted identification information may also have indication information corresponding to the indicator. At this time, the constructing apparatus 13 for the correspondence between the microphone and the sound card channel acquires corresponding instruction information from the identification information and acquires corresponding instruction words from the test information, and the constructing apparatus 13 for the correspondence between the microphone and the sound card channel can establish the correspondence between the identification information and the test information by using the instruction information and the instruction words as intermediate information only by comparing the instruction information and the instruction words. Illustratively, the test information a carries the indicator "southwest corner", the test information B carries the indicator "northwest corner", the test information C carries the indicator "southeast corner", and the test information D carries the indicator "northeast corner". Identification information e is provided with indication information 'southwest corner', identification information f is provided with indication information 'northwest corner', identification information g is provided with indication information 'southeast corner', identification information h is provided with indication information 'northeast corner', and second mapping information 'identification information e-test information A' can be obtained based on each indication word and indication information; identification information f-test information B; identification information g-test information C; identification information h-test information D ".
The preset identification mode may adopt one or a combination of several types, and when a combination of several types of identification modes is adopted, the identification process corresponding to each identification mode refers to the identification process disclosed above, and is not described herein again.
In some embodiments, based on the second mapping information, it may be determined whether a microphone is available. Specifically, if the identification information does not exist, the microphone is not available, that is, the microphone cannot receive sound; if the identification information is invalid information such as messy codes, the microphone is not usable, namely the microphone can receive sound, but the sound receiving quality is poor, such as excessive noise.
Further, if the above situation exists, before the corresponding relationship between the microphone and the sound card channel is constructed, the invalid information may be removed from the acquired identification information, so as to avoid affecting the subsequent comparison process.
S403, constructing a corresponding relation between the microphone and the sound card channel based on the first mapping information and the second mapping information.
Based on the above description, it can be seen that the first mapping information reflects a corresponding relationship between the test information and the microphone, and the second mapping information reflects a corresponding relationship between the test information and the identification information, and it can be seen that, if the same amount of test information exists in both the first mapping information and the second mapping information, the test information can be used as intermediate information to construct a corresponding relationship between the identification information and the microphone. Further, since the identification information and the sound card channel have a corresponding relationship, the identification information may be used as intermediate information to construct a corresponding relationship between the microphone and the sound card channel, which may refer to the construction process shown in fig. 6, and specifically includes the following steps:
s601, the identification information is used as target identification information one by one, and target test information corresponding to the target identification information is obtained from the second mapping information.
And S602, acquiring a target microphone corresponding to the target test information from the first mapping information.
S603, establishing a corresponding relation between a target sound card channel corresponding to the target identification information and the target microphone.
In this embodiment, the identification information to be compared is referred to as target test information, and first, the test information corresponding to the target identification information, i.e., the target test information, is selected from the second mapping information. And acquiring a microphone corresponding to the target test information, namely a target microphone, from the first mapping information.
