The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.

Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the far-field speech adaptation device and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.

As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a far-field speech adaptation program.

In the far-field speech adaptation device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the far-field speech adaptation device of the present invention may be provided in the far-field speech adaptation device, and the far-field speech adaptation device calls the far-field speech adaptation program stored in the memory 1005 through the processor 1001 and executes the far-field speech adaptation method provided by the embodiment of the present invention.

An embodiment of the present invention provides a far-field speech adaptation method, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the far-field speech adaptation method according to the present invention.

In this embodiment, the far-field speech adaptation method includes the following steps:

step S10: and when a far-field voice adaptation scheme switching instruction is detected, modifying the far-field voice configuration item in the initial configuration file to obtain a target configuration file.

It should be noted that the execution subject of the present embodiment may be the far-field speech adaptation device with the data processing, network communication, and program running functions, for example: the television may also be other devices capable of implementing the same or similar functions, and this embodiment is not particularly limited to this. In this embodiment and the following embodiments, the far-field speech adaptation method of the present invention is described by taking a television as an example.

It is understood that the far-field speech adaptation scheme switching instruction refers to an instruction to switch the current far-field speech adaptation scheme.

It will be appreciated that a configuration file is a computer file that can configure parameters and initial settings for some computer programs, the configuration file including annotation content and configuration item content, and thus, the configuration file can be modified by modifying the configuration item content.

In a specific implementation, the remote speech configuration items may include a built-in microphone, an algorithm type, a company name, a microphone number, a performance function attribute, a hotword function, a voiceprint function, and the like, and the remote speech configuration items are already configured with corresponding values, and this embodiment is not particularly limited to specific values, and this embodiment is also not particularly limited to the content of the far-field speech configuration item.

Further, to acquire the initial configuration file, before the step S10, the method further includes: acquiring key identification information, and searching target configuration data corresponding to the key identification information in a preset mapping relation; and configuring the default configuration file according to the target configuration data to obtain an initial configuration file.

It should be noted that the key identification information refers to information capable of identifying the attribute of the current system, for example: the model and the chip have corresponding configuration data for each type and chip of television, and the type of the key identification information is not specifically limited in this embodiment.

It can be understood that, a developer in the preset mapping relationship may pre-store the corresponding relationship between the key identification information and the configuration data, so that the target configuration data corresponding to the current key identification information may be found through the preset mapping relationship.

In a specific implementation, the default configuration file may be a blank configuration file, and the initial configuration file may be obtained by adding the target configuration data to the default configuration file.

According to the embodiment, the initial configuration file is obtained according to the key identification information, and different configuration files are configured for each type of equipment, so that the initial configuration file can be more accurate, and a far-field voice adaptation scheme can be automatically switched.

Step S20: and analyzing the target configuration file to generate an attribute configuration item.

Further, the step S20 includes: restarting the system service, and analyzing the target configuration file through a preset program when restarting is completed to generate an attribute configuration item.

It should be noted that the preset program refers to a code which is written in advance by a developer and added into the system, and can be analyzed again after restarting the system service, for a user, the television can be restarted when the developer wants to restart, and for the developer, the upper-layer application and the bottom-layer service can be restarted when the developer wants to restart.

It can be understood that the attribute configuration items may include whether there are multiple audio functions, whether there is a built-in microphone, whether the algorithm is a software algorithm or a DSP algorithm, a company name, a serial number of the microphone, how many channels the microphone has, whether voiceprints are supported, whether hotwords are supported, and the like, and may further include other attribute configuration items, which is not particularly limited in this embodiment.

In the embodiment, the system service is restarted, and the configuration file can be reanalyzed, so that the content of the attribute configuration item can be more accurate, and a far-field voice adaptation scheme can be automatically switched.

Step S30: and switching the current far-field voice adaptation scheme according to the attribute configuration item.

It can be understood that each attribute configuration item is assigned with a value, and the current remote voice adaptation scheme can be switched according to the value of each attribute configuration item.

Further, after step S30, the method further includes: determining a target far-field voice adaptation scheme according to a switching result; acquiring adaptation effect data of the target far-field voice adaptation scheme; and when the adaptation effect data does not meet the preset condition, switching the target far-field voice adaptation scheme.

It can be understood that after the switching of the current far-field speech adaptation scheme, the target far-field speech adaptation scheme after the switching, i.e. an adaptation scheme between the upper layer application and the bottom layer service, can be obtained.

It should be understood that the fitting effect data refers to the fitting effect data of the target far-field speech fitting scheme and the current system. The preset condition refers to a condition preset by a developer, and may be set such that the occupancy of the CPU does not exceed a certain value, for example: 10%, 15%, etc., which are not specifically limited by the present embodiment, and the preset condition may be set according to the actual situation, which is also not specifically limited by the present embodiment.

In a specific implementation, when a target far-field speech adaptation scheme is an upper-layer application adaptation scheme, if the adaptation effect is not good, switching to a bottom-layer service adaptation scheme is performed, and if the adaptation effect is good, switching is not required; when the target far-field voice adaptation scheme is the bottom-layer service adaptation scheme, if the adaptation effect is not good, switching to the upper-layer application adaptation scheme is performed, and if the adaptation effect is good, switching is not needed.

The embodiment also judges the adaptation effect of the switched far-field speech adaptation scheme after the switching of the current far-field speech adaptation scheme, and can automatically switch to another far-field speech adaptation scheme under the condition of poor adaptation effect, thereby improving the user experience.

In this embodiment, when a far-field speech adaptation scheme switching instruction is detected, a far-field speech configuration item in an initial configuration file is modified to obtain a target configuration file, and then the target configuration file is analyzed to generate an attribute configuration item, and then a current far-field speech adaptation scheme is switched according to the attribute configuration item. In this embodiment, a required target configuration file can be obtained by modifying a far-field voice configuration item in an initial configuration file, then the target configuration file is re-analyzed, and the attribute configuration item generated after analysis is switched to a required far-field voice adaptation scheme.

Referring to fig. 3, fig. 3 is a flowchart illustrating a far-field speech adaptation method according to a second embodiment of the present invention.

Based on the first embodiment described above, in the present embodiment, the step S10 includes:

step S101: and when a far-field voice adaptation scheme switching instruction is detected, selecting a target automation script from the pre-configured automation scripts according to the far-field voice adaptation scheme switching instruction.

It should be noted that the preconfigured automation script is a script that is written into the system by the developer in advance, and the script can modify the configuration items in the configuration file.

It can be understood that there is one corresponding automation script for each far-field speech adaptation scheme, so that a target automation script corresponding to an instruction needs to be selected from preconfigured automation scripts according to a far-field speech adaptation scheme switching instruction. For example: when the far-field voice adaptation scheme switching instruction is to switch to an upper-layer application scheme, selecting a script related to an upper-layer application from the pre-configured automatic scripts; when the far-field voice adaptation scheme switching instruction is to switch to the lower-layer service scheme, a script related to the lower-layer service needs to be selected from the pre-configured automation scripts.

Step S102: and modifying each far-field voice configuration item in the initial configuration file through the target automation script to obtain a target configuration file.

It can be understood that, since the present embodiment is modified for the far-field speech adaptation scheme, only the configuration items related to the far-field speech need to be modified to implement the scheme of the present embodiment.

In a specific implementation, the target automation script may modify a value corresponding to the configuration item, for example: the target configuration file may be obtained by modifying values corresponding to the built-in microphone, the algorithm type, the company name, the microphone number, the performance function attribute, the hotword function, and the voiceprint function, and may include other types.

In the embodiment, when a far-field voice adaptation scheme switching instruction is detected, a target automation script is selected from pre-configured automation scripts according to the far-field voice adaptation scheme switching instruction, and then each far-field voice configuration item in an initial configuration file is modified through the target automation script to obtain a target configuration file. In the embodiment, each far-field voice configuration item in the initial configuration file is modified through the target automation script, so that the far-field voice configuration item can be modified more quickly and conveniently, and a far-field voice adaptation scheme can be automatically switched.

Referring to fig. 4, fig. 4 is a flowchart illustrating a far-field speech adaptation method according to a third embodiment of the present invention.

Based on the above embodiments, in the present embodiment, the step S30 includes:

step S301: and determining the configuration type of the attribute configuration item according to the identification information in the attribute configuration item.

It should be noted that the identification information refers to information that can be identified for each configuration type carried in the attribute configuration item.

In a specific implementation, the configuration types are mainly divided into two types, one is an upper layer application type, and the other is a bottom layer service type, the upper layer application type refers to that the upper layer acquires original data to perform awakening and front-end processing, and the bottom layer service type refers to that the bottom layer awakens and the front-end processing of the recorded data. Both types have advantages and disadvantages, and for the upper application type, the workload of the underlying migration is small, and the workload of the application is large, and for the upper application type, the opposite is true.

Step S302: and switching the current far-field voice adaptation scheme according to the configuration type.

Further, the step S302 includes: when the configuration type is an upper application type, switching the current far-field voice adaptation scheme to an upper application adaptation scheme; and when the configuration type is the bottom-layer service type, switching the current far-field voice adaptation scheme to the bottom-layer service adaptation scheme.

In concrete implementation, after the far-field voice adaptation scheme is switched, developers can test whether the scheme is perfect or not, and compare, verify and mutually reference, so that the far-field voice adaptation efficiency of equipment is improved, and the product can be rapidly landed.

In the embodiment, the far-field speech adaptation schemes are switched through the configuration types, and each configuration type has a corresponding switching scheme, so that the schemes can be switched more conveniently and automatically.

It is understood that the far-field speech adaptation scheme may not have only the two schemes, but for other far-field speech adaptation schemes, two or more far-field speech schemes may be adapted on the same hardware and software platform by the above-described embodiment of the present invention, and the switching of the far-field speech adaptation scheme is performed.

In this embodiment, the configuration type of the attribute configuration item is determined according to the identification information in the attribute configuration item, and then the current far-field speech adaptation scheme is switched according to the configuration type. The embodiment determines the configuration type through the identification information, and not only determines the configuration type through the attribute configuration item, so that the embodiment can more accurately determine the configuration type, and can automatically switch the far-field voice adaptation scheme by switching the current far-field voice adaptation scheme according to the configuration type.

Furthermore, an embodiment of the present invention further provides a storage medium, where the storage medium stores a far-field speech adaptation program, and the far-field speech adaptation program, when executed by a processor, implements the far-field speech adaptation method as described above.
