The following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting a code rate according to an embodiment of the present application, where the method for adjusting a code rate described in the embodiment is applied to an electronic device as shown in fig. 1, and the method for adjusting a code rate includes:
s201, in the process of carrying out Bluetooth voice call through the Bluetooth communication module, the electronic equipment acquires preset parameters of the electronic equipment, wherein the preset parameters comprise at least one of the following parameters: the change trend of the distance between the electronic equipment and the equipment at the opposite end of the call, the distance parameter and the signal quality.
The preset parameters may further include a signal-to-noise ratio, a channel quality, an output power, a total harmonic, and the like, which are not limited herein.
S202, the electronic equipment dynamically adjusts the code rate of the vocoder according to the preset parameters.
Wherein, the code rate of the vocoder is the coding code rate.
Wherein the dynamic adjustment may adjust a high code rate to a low code rate or a low code rate to a low code rate.
S203, the electronic equipment encodes the original voice data according to the adjusted code rate to obtain target voice data.
And S204, the electronic equipment sends the target voice data to opposite-end equipment through the Bluetooth communication module.
Optionally, detecting the target voice data; judging whether blank voice data exists in the target voice data or not; and if the blank voice data exists, readjusting the code rate of the vocoder.
It can be seen that the method for adjusting a code rate and the related product described in the embodiments of the present application are applied to an electronic device, where the electronic device includes a bluetooth communication module, and first, in a process of performing a bluetooth voice call through the bluetooth communication module, a preset parameter of the electronic device is obtained, where the preset parameter includes at least one of: the method comprises the steps of obtaining a target voice data, and sending the target voice data to an opposite terminal device through a Bluetooth communication module. Therefore, the electronic equipment monitors the preset parameters in real time in the process of carrying out the Bluetooth voice call, and adjusts the code rate of the vocoder in time, thereby effectively avoiding the conditions of delay, packet loss and the like in the Bluetooth voice call, ensuring that the best voice quality can be provided in any network scene, and being beneficial to improving the intelligence and the accuracy of the electronic equipment in the process of adjusting the code rate.
In one possible example, the preset parameter includes a trend of a change in a distance between the electronic device and a device at the opposite end of the call, and the dynamically adjusting the code rate of the vocoder according to the preset parameter includes: detecting the variation trend of the distance between the electronic equipment and the opposite-end equipment for communication; adjusting the step length according to the change trend; querying a preset database to obtain a target code rate corresponding to the adjusted step length, wherein the preset database comprises a mapping relation between the step length and the code rate; and updating the code rate of the vocoder according to the target code rate.
The mapping relationship between the step size and the code rate may include, but is not limited to, one-to-one, one-to-many, many-to-many, and the like, and is not limited herein.
For example, when the electronic device detects that the variation trend is increasing or decreasing in the first time period, the code rate starts to be adjusted, if the step size is reduced by one step size every 5 meters, the corresponding target code rate is found according to the step size, and the target code rate is updated. The step length can be obtained by analyzing and calculating historical data, that is, the relationship between the step length and the change trend of the distance can be obtained by analyzing and calculating the historical data.
Therefore, in this example, in the process of performing the bluetooth call, the step length is changed based on the change trend of the distance, and then the code rate of the vocoder is dynamically adjusted, thereby avoiding the occurrence of delay and packet loss caused by poor call quality in the bluetooth call process, and being beneficial to improving the intelligence and accuracy of the electronic device in adjusting the code rate.
In one possible example, the adjusting the step size according to the variation trend includes: analyzing the change stage of the change trend according to historical data; and determining the corresponding step length according to the change stage.
The change stage may be dynamically adjusted according to the location of the electronic device, for example, in a remote mountain area, one stage with five step lengths, in a busy urban area, one stage with three step lengths, and the like, which is not limited herein.
Therefore, in this example, the electronic device dynamically adjusts the step lengths under different transformation trends according to different variation trends, so as to flexibly adjust the code rate, ensure that good call quality can be provided under any circumstances, and be beneficial to improving the intelligence and flexibility of the electronic device in adjusting the code rate.
In one possible example, the preset parameter includes signal quality, and the dynamically adjusting the code rate of the vocoder according to the preset parameter includes: detecting the current signal quality; scoring according to the signal quality to obtain a target score; and adjusting the code rate of the vocoder according to the target score.
The scoring can be performed according to a preset scoring calculation strategy, and the preset scoring calculation strategy can be obtained by integrating semantic analysis, interruption times, noise ratio and the like of the call records, and is not limited uniquely here.
Optionally, the electronic device queries a preset score-code rate list according to the target score, obtains a corresponding code rate according to the preset score-code rate list, and adjusts the code rate.
For example, the electronic device scores the current signal quality according to the number of times of interruption of the bluetooth call, and if the bluetooth call is interrupted for 5 times within ten minutes, the score of the current signal quality is 50 minutes, the code rate of the vocoder is changed from the high code rate to the low code rate.
Therefore, in this example, the electronic device may score according to the quality of the signal, and dynamically adjust the code rate of the vocoder according to the score, that is, timely determine the network state of the current electronic device, and perform timely response, which is beneficial to improving the intelligence and flexibility of the electronic device in adjusting the code rate.
In one possible example, the preset parameter includes a distance parameter, and the dynamically adjusting the code rate of the vocoder according to the preset parameter includes: acquiring a target position of the current electronic equipment; determining a target range of the distance parameter according to the target position; acquiring a first distance from a first terminal to an opposite terminal; if the first distance exceeds the target range, inquiring a code rate-distance list to obtain a target code rate; and updating the code rate of the vocoder according to the target code rate.
The corresponding relation between the target position and the target range of the distance parameter can be preset, and the target range of the distance parameter is dynamically changed according to the specific situation of the current position.
The data in the code rate-distance list can be obtained through historical data statistics or can be customized according to a factory manufacturer at the time of factory shipment, and the data is not limited uniquely here.
Therefore, in this example, the electronic device dynamically adjusts according to different distance parameters to obtain different code rates, which is beneficial to more flexibly adjusting the code rates when the electronic device is in a motion state, and improves intelligence and flexibility of the electronic device in the process of adjusting the code rates.
In one possible example, after the dynamically adjusting the code rate of the vocoder according to the preset parameter, the method further comprises: continuously monitoring the adjusted code rate; if the adjusted code rate is not within the preset threshold range, performing secondary adjustment to obtain a reference code rate; and setting the reference code rate in a preset time length for updating.
The preset threshold range may be obtained according to historical data, obtained according to big data analysis, or determined by a manufacturer at the time of factory shipment, and is not limited uniquely here.
The preset duration can be obtained according to historical data, obtained according to big data analysis or determined by a manufacturer when leaving a factory, and is not limited uniquely here.
Therefore, in this example, the electronic device avoids the influence of frequent switching on the interruption of the voice call by monitoring the code rate and adjusting the switching time, that is, after the time length between two times of switching with different code rates is set to be longer than a certain time length, the switching is allowed, so that the intelligence and flexibility in the process of adjusting the code rate can be improved.
In a possible example, after the original speech data is encoded according to the adjusted code rate to obtain the target speech data, the method further includes: determining the type of the target voice data; acquiring a code rate corresponding to the data type of the target voice data as a target code rate according to the preset corresponding relation between the type of the voice data and the code rate; and acquiring a code rate range of the target code rate as a preset code rate threshold range.
The different types of voice data may correspond to different coding rates, and a correspondence between the types of the voice data and the coding rates is preset and stored in the electronic device, where the correspondence may be one-to-one, one-to-many, or many-to-many, and is not limited herein.
The coding rate corresponding to the type with higher requirement on the real-time performance can be lower than the coding rate of the type with higher requirement on the tone quality, and particularly, the coding rate corresponding to the different types can be obtained according to the big data.
Optionally, when the bluetooth voice call of the electronic device is started, the encoding rate corresponding to the type of the voice data is greater than a preset code rate threshold; and when the Bluetooth voice call is disconnected, the encoding rate corresponding to the type of the voice data is smaller than a preset code rate threshold value.
Therefore, in this example, the electronic device flexibly adjusts different code rates according to different voice data types, and further obtains a preset code rate threshold range during secondary adjustment, which is beneficial to intelligence and accuracy in the process of adjusting the code rate.
