Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, there is provided a bluetooth headset control method including the steps of:
s110, detecting that the Bluetooth headset is in an in-ear state, and acquiring sound information;
wherein, the in-ear state is the state that the Bluetooth headset is worn in the ear of a person.
Specifically, any technical means in the art can be adopted to detect the state of the bluetooth headset. For example: whether the Bluetooth headset is in an in-ear state or not can be judged according to electric signals transmitted by an infrared sensor arranged in the Bluetooth headset. The edge of bluetooth headset's sound outlet is located to infrared sensor. The sound information is acquired when the Bluetooth headset is detected to be in the in-ear state. In one specific example, the collection may be performed by a sound collection device, and the sound information may be acquired from the sound collection device. The sound information may be emitted by a human body.
S120, sequentially carrying out audio preprocessing and feature extraction processing on the sound information to obtain sound features; wherein the sound features comprise input content information, input voiceprints and voice frequency;
the voiceprint is a quantized value obtained by Fourier variation of a ripple of sound, and can be obtained by performing feature extraction on preprocessed sound information. The voice frequency of the user is the distance of each character voice, and the input content information is the character content contained in the voice and can be converted by any means in the field.
Specifically, the audio preprocessing method includes pre-emphasis, framing, windowing, and the like, and is used for eliminating the influence of aliasing, higher harmonic distortion, high frequency, and the like caused by the human vocal organs and the equipment for acquiring the voice signals on the quality of the voice signals. The signals obtained by subsequent voice processing are ensured to be more uniform and smooth as much as possible, high-quality parameters are provided for signal parameter extraction, and the voice processing quality is improved.
The feature extraction is to extract or reduce the influence of information irrelevant to recognition in the voice signal as much as possible, reduce the data amount to be processed in the subsequent recognition stage, and generate feature parameters representing speaker information carried in the voice signal. In this step, any technical means in the field may be adopted to perform feature extraction processing on the voice information after the audio preprocessing, so as to obtain voice features.
S130, receiving preset information; the preset information comprises preset content information, a preset voiceprint and a preset frequency value;
specifically, the preset content information, the preset voiceprint and the preset frequency value correspond to the input content information, the input voiceprint and the voiceprint frequency, respectively. The preset information may be stored in a certain memory in advance. When feature comparison is needed, preset information is directly extracted from the memory for comparison to obtain a comparison result
S140, acquiring a first comparison result of the input content information and the preset content information, a second comparison result of the input voiceprint and the preset voiceprint, and a third comparison result of the voice frequency and the preset frequency value;
specifically, any comparison method in the art may be adopted to perform comparison between the input content information and the preset content information, comparison between the input voiceprint and the preset voiceprint, and comparison between the voiceprint frequency and the preset frequency value, and obtain comparison results respectively. The "first, second and third" of the first, second and third alignments are used only as distinguishing alignments.
And S150, indicating the communication equipment of the Bluetooth headset to be connected or disconnected with the user terminal according to the first comparison result, the second comparison result and the third comparison result.
The alignment results may include alignment success and alignment failure. The sound feature may include a plurality of features, and may be specific depending on the features included in the preset information. In the case where the sound features include a plurality of features, the condition of successful comparison may be that the feature judgment of the preset number of terms is the same. For example, when the sound features are 3 features, the comparison is successful when the three features are all judged to be consistent with the preset information; or the comparison is successful only when the two characteristic judgments are consistent with the preset information. The above condition for determining consistency may be any one of the manners in the art, and is not limited herein. In one embodiment, the step of instructing the communication device of the bluetooth headset to connect or disconnect with the user terminal according to the first comparison result, the second comparison result, and the third comparison result includes: if the first comparison result, the second comparison result and the third comparison result are successful, indicating the communication equipment of the Bluetooth headset to be connected with the user terminal; and if any one of the first comparison result, the second comparison result and the third comparison result is a comparison failure, indicating the communication equipment of the Bluetooth headset to be disconnected from the user terminal.
The bluetooth headset control method can be applied to the situation that the bluetooth headset is lost, when the traditional bluetooth headset transmits data between the mobile phone terminal and the bluetooth headset, the traditional bluetooth headset is generally connected with the mobile phone end through the left headset, and when the mobile phone end transmits the data to the left headset, the right headset monitors the data, so that the communication between the headset and the mobile phone end is realized (as shown in fig. 2). The bluetooth headset control method of the present application is applied to a bluetooth headset, so that the bluetooth headset needs to pass the verification of the sound information after being worn in the ear of a person (as shown in fig. 3). Before this, even through being connected with left earphone bluetooth through the cell-phone end, also can't carry out normal bluetooth communication.
According to the Bluetooth headset control method, when the Bluetooth headset is detected to be in an in-ear state, sound information is acquired, sound characteristics in the sound information are compared with preset characteristics, when the comparison is successful, communication equipment in the Bluetooth headset is connected with a user terminal, and when the comparison is failed, the Bluetooth headset cannot be connected with the user terminal. By the Bluetooth headset control method, a user of a non-original Bluetooth headset cannot use the Bluetooth headset when the Bluetooth headset is lost, so that a pick-up person does not take away the Bluetooth headset, the safety of the Bluetooth headset is improved, and the Bluetooth headset can be conveniently found.
In one embodiment, as shown in fig. 4, the step of obtaining the second comparison result between the input voiceprint and the preset voiceprint includes:
s410, acquiring the coincidence degree of the input voiceprint and a preset voiceprint;
the voiceprint is a quantized value obtained by Fourier variation of a ripple of sound, and can be obtained by performing feature extraction on preprocessed sound information.
Specifically, the goodness of fit of the two voiceprints can be obtained by any technical means in the field.
S420, if the goodness of fit is larger than or equal to a set value, the comparison is successful;
and S420, if the goodness of fit is smaller than a set value, the comparison fails.
The set value can be set according to specific conditions. For example: the set value may be 90%.
The process of comparing the sound characteristics with the preset information is mainly used for judging whether the obtained sound information is the sound of the original user.
In one embodiment, the preset frequency value comprises a preset interval range and a preset frequency difference value;
as shown in fig. 5, the step of obtaining a third comparison result between the sound frequency and the preset frequency value includes:
s510, if each sound frequency falls into a preset interval range or the difference value of adjacent sound frequencies is smaller than a preset difference value, the comparison is successful;
s520, if each sound frequency does not fall within the preset interval range and the difference between adjacent sound frequencies is greater than or equal to the preset difference, the comparison fails.
Specifically, whether the comparison is successful or not is judged through a set rule, if each sound frequency falls into a preset interval range or the difference value of adjacent sound frequencies is smaller than a preset difference value, the comparison is successful, and if not, the comparison is failed. In one specific example, the rule may be: the difference between every two sound insulation of the 1 st sound insulation and the 2 nd sound insulation of the nth sound insulation cannot be smaller than 0.05s, or a fixed range value is set for every sound insulation, for example, every sound insulation is 0.1s (upper and lower floating 0.01s), and the comparison is successful when the condition in the rule is met.
In another example, the step of comparing the sound characteristic with the preset information to obtain the comparison result includes: if the sound frequencies fall into the preset interval range, the comparison is successful; if the sound frequencies do not fall into the preset interval range, the comparison fails.
In another example, the step of comparing the sound characteristic with the preset information to obtain the comparison result includes: if the difference value of the adjacent sound frequencies is smaller than the preset difference value, the comparison is successful; and if the difference value of the adjacent sound frequencies is greater than or equal to the preset difference value, the comparison fails.
The method is used for further accurately locking the pronunciation habit of the original user by judging through the sound frequency, and the accuracy of the voice verification is improved.
In one embodiment, as shown in fig. 6, the step of obtaining the first comparison result between the input content information and the preset content information includes:
s610, if the input content information is consistent with the preset content information, the comparison is successful;
s620, if the input content information is different from the preset content information, the comparison fails.
Through the setting of the preset content information, the voice password can be set, and only under the condition that the voice passwords are consistent, the comparison is successful, namely, the password verification is passed.
In one embodiment, as shown in fig. 7, there is provided a bluetooth headset control method including the steps of:
