Referring to fig. 4, another embodiment of the present application provides a device pairing connection method, which can be applied to a first device, and the method can include steps S210 to S250.

Step S210, in the pairing mode, acquiring identity information of the first device.

In an embodiment of the present application, a first device acquires identity information of the first device in a pairing mode.

In an embodiment of the present application, the identity information of the first device includes, but is not limited to, one or more of a physical address, a device identification, and a device type identification of the first device. Where the physical address is an identifier used to tag each device in the network. The physical address of each device in the network is different. The device identification may include a device ID (device ID), an IMEI (International Mobile Equipment Identity), and the like. The device type identifier may include a door type of the device, such as a smart speaker, a smart desk lamp, and the like.

In an embodiment of the present application, the identity information of the first device may be stored in a memory of the first device in advance, and in the pairing mode, the first device retrieves the identity information of the first device from the memory.

And S220, determining the target voiceprint characteristics according to the identity information of the first equipment.

In an embodiment of the application, the first device determines the target voiceprint feature according to the identity information of the first device.

In some embodiments, the first device may determine, according to the identity information of the first device and the first preset correspondence, a target voiceprint feature corresponding to the identity information of the first device. The first preset corresponding relation represents the corresponding relation between the identity information of the first device and the target voiceprint feature.

As an embodiment, the target voiceprint characteristics include one or more of a fundamental frequency parameter, a formant parameter, a harmonic parameter.

The fundamental frequency (fundamental frequency) parameter refers to the lowest oscillation frequency of the free oscillation system, and refers to the lowest frequency in the complex wave. Wherein the higher the fundamental frequency parameter, the sharper the emitted sound.

The formants refer to regions where energy is relatively concentrated in the frequency spectrum of sound, and the sound is filtered by the cavity when passing through the resonant cavity, so that energy of different frequencies in the frequency domain is redistributed, one part is strengthened due to the resonance of the resonant cavity, and the other part is attenuated. Since the energy distribution is not uniform, the strong portion is called a formant as if it were a mountain peak. Formants determine the quality of vowels, and are important parameters for determining timbre and tone quality. The formant parameters may include formant frequency, frequency bandwidth, amplitude, and the like.

Harmonic parameters refer to vibrations of other frequencies in the sound than the fundamental frequency, and the superposition or subtraction of these vibrations produces the appearance of vibrations of more frequencies, i.e. harmonics. The harmonic parameters include the frequency, the magnitude, the proportion of vibration and the like of other vibration besides the fundamental frequency in the sound.

Optionally, the first preset corresponding relationship may be that the device type identifier determines a fundamental frequency parameter. The device type may include different types such as a smart television, a smart lamp, a smart air conditioner, and the like, and illustratively, the device type identifier a may represent the smart television, the device type identifier B may represent the smart lamp, and the device type identifier C may represent the smart air conditioner; the first preset corresponding relationship may be that the fundamental frequency parameter of the device type identifier a is 100Hz, the fundamental frequency parameter of the device type identifier B is 150Hz, and the fundamental frequency parameter of the device type C is 200Hz. Therefore, the fundamental frequency parameter can be determined through the device type identifier and the first preset corresponding relationship, and it can be understood that the application is not limited thereto, and the first preset corresponding relationship can also be set according to actual use needs.

Optionally, the first preset correspondence may be that the identifier of the device determines a harmonic parameter. The identification of the devices is used to characterize the unique identification of each device for use in distinguishing each different device. The identity of the device may for example be an identification code for characterising the device. The first preset corresponding relationship may be set according to a difference in format of the identification code. For example in terms of the number of digits, type of identification code, etc. Illustratively, if the device identifier is a 3-bit digital code, the first predetermined relationship may be that a harmonic is set and its frequency value corresponds to the 3-bit digital code of the device identifier. Such as: if the identifier of the device 1 is "111", the corresponding harmonic parameter is 111Hz; device 2 is identified as "160" and its corresponding harmonic parameter is 160Hz. In some embodiments, due to different identification formats of the devices, the identifier of the device cannot be completely represented by only using the frequency of one harmonic, in this case, the first preset relationship may also be that the identifiers of the devices are represented by the frequencies of multiple harmonics together, and the order of the identifiers may be determined by the proportion of the harmonics, for example, the higher proportion of the harmonics may be ranked earlier. Illustratively, the device 3 is identified as "120230", the first preset relationship may be that the harmonic parameter of the first harmonic corresponding to the device 3 is 120Hz, the harmonic parameter of the second harmonic is 230Hz, and the proportion of the first harmonic is greater than that of the second harmonic. When the identification of the equipment is confirmed, the sequence can be determined by the harmonic parameter 120Hz of the first harmonic, the harmonic parameter 230Hz of the second harmonic and the proportion of the two, so that the identification of the equipment is '120230'. It can be understood that the present application is not limited thereto, and the first preset corresponding relationship may also be set according to actual use requirements.

Alternatively, the first preset correspondence may be that the physical address of the device determines the formant parameter. The physical address is an identifier used to mark each device in the network. The physical address of the target device is obtained, and then data can be transmitted and received to and from the target device. The first predetermined relationship may correspond the formant parameters to physical addresses. Illustratively, the physical address may be composed of 6 sub-addresses, each of which is a 16-ary number, such as: 00-0D-87-ED-5E-6F, each sub-address can be represented by 6 formants, and the amplitude of each formant represents the value of each sub-address, and for convenience of representation, a 16-system number of each sub-address can be converted into a 10-system number and represented by the amplitude of the formant. And the order of each sub-address may be sorted according to the frequency of the formants, for example, the order of the smaller frequency is first. Illustratively, the physical address of the device: 00-0D-87-ED-5E-6F includes the first sub-address "00" being converted to 10 to "00", i.e., the corresponding first formant has an amplitude of 0dB. The second sub-address "0D" is converted to 10 to be "13", that is, the amplitude of the corresponding second formant is 13dB. The third sub-address "87" is converted to 10 and then to "135", that is, the amplitude of the corresponding third formant is 135dB. The fourth sub-address "ED" is converted to 10 and then is "237", that is, the amplitude of the corresponding fourth formant is 237dB. The fifth sub-address "5E" is converted to 10 and then "94", that is, the amplitude of the corresponding fifth formant is 94dB. The sixth sub-address "6F" is converted to 10 and then becomes "111", that is, the amplitude of the corresponding sixth formant is 111dB. Wherein the frequency magnitude relation of each formant is as follows: and determining the order of the sub-addresses according to the frequency of the formants, and finally determining the physical address of the equipment. It is to be understood that the present application is not limited thereto, and the first preset corresponding relationship may also be set according to actual use requirements, for example, the order of the sub-addresses may also be determined by different amplitudes, the sub-addresses may also be determined by frequency values of formants, and the like.
