It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.

In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of an apparatus configuration method according to an embodiment of the present invention, where the present embodiment is applicable to a case of performing equalizer parameter configuration on an intelligent apparatus, and the method may be executed by an apparatus configuration device, where the apparatus may be implemented in a software and/or hardware manner, and is preferably configured in an intelligent apparatus having audio playing and voice recognition functions, such as an intelligent sound box. The method specifically comprises the following steps:
s110, determining a target equalizer parameter range according to a target use distance of the equipment to be configured and a mapping relation between the candidate use distance and the candidate equalizer parameter range; wherein, the candidate equalizer parameter range is determined according to the voice response rate under the candidate use distance.
In the specific embodiment of the present invention, the device to be configured refers to an intelligent device having both audio playing and voice recognition functions, such as an intelligent sound box and a smart phone. The use distance of the device to be configured is a distance between a user and the device to be configured when the user uses the device to be configured, for example, the user sits on one side of a writing desk with a width of 1m, and fixes and sets the smart sound box on the other side of the writing desk, so that the use distance of the smart sound box is about 1m currently. The target use distance refers to a use distance of the device to be configured in different use scenes, for example, 1m in the above-mentioned scenes. And the candidate use distance refers to an available distance of the device to be configured, for example, at least one of 0-5 m.
In this embodiment, the equalizer is a module for adjusting the amplification amount of each frequency component electrical signal in the intelligent device, and the equalizer realizes the effects of compensating the curves of the speaker and the sound field, compensating and modifying various sound sources, and the like by adjusting the electrical signals with different frequencies. In this embodiment, devices with the same model as various devices to be configured may be adopted as devices to be tested in advance, and by testing the values of the equalizer parameter ranges of the devices to be tested at different candidate use distances, the establishment of the mapping relationship between the candidate use distances and the candidate equalizer parameter ranges is realized, so that when the devices to be configured perform the configuration of the equalizer parameters, the target equalizer parameter ranges are determined directly according to the target use distances of the devices to be configured and the mapping relationship between the candidate use distances and the candidate equalizer parameter ranges.
Specifically, under each candidate use distance, the present embodiment determines the candidate equalizer parameter range according to the voice response rate of the device under test to the voice control instruction. The voice response rate is the ratio of the number of successful responses of the equipment to the total number of voice commands under the control of a certain number of voice commands. For example, the number of successful awakenings of the device under test on 100 voice awakening words is the awakening rate. The equalizer parameter range refers to the range of equalizer parameters that can be adjusted under the condition that the tested device meets a certain voice response rate, and the equalizer parameter range is different under different use distances. Before configuring the equalizer parameters of the device, the embodiment may use the voice response rate as a precondition, and construct a mapping relationship between the use distance and the equalizer parameter range by testing the equalizer parameter range of the device under test at different use distances.
Exemplarily, in a test scene, a dummy and the like can be selected in advance as a voice simulation sound source, an intelligent device with the same model as that of the device to be configured is selected as the device to be tested for testing, and the equalizer curve is burned into the device to be tested. In the available distance range of the equipment, a plurality of distances can be selected in advance to serve as candidate using distances respectively, and the distance between the equipment to be tested and the voice simulation sound source is fixed to serve as the candidate using distance.
In the testing process, the tested device is controlled to play white noise with the maximum volume, the voice simulation sound source is controlled to play voice commands with certain frequency and times, and the sound pressure level of the voice simulation sound source is adjusted to be standard sound pressure, such as 94 dB. And determining the response result of the tested device to each voice instruction, and calculating the voice response rate of the tested device at the current candidate using distance. The reverberation time of the device under test at the current candidate use distance may be recorded, and if the reverberation time exceeds the standard reverberation time range, for example, 0.3 to 0.6s, the test of the equalizer parameter at the candidate use distance is ended. And finally, determining the candidate equalizer parameter range of the tested device under the candidate use distance according to the voice response rate of the tested device.
For example, if the voice response rate of the device under test is less than the first response rate threshold, that is, the voice response rate condition is not satisfied, the gain of the equalizer parameter in the device under test at the low frequency component is reduced, for example, the gain of the frequency component of 50-300Hz is reduced, so as to reduce the THD of the loudspeaker at the low frequency band, and improve the echo cancellation processing effect of AEC, until the obtained voice response rate is equal to the first response rate threshold, that is, the voice response rate condition is satisfied, the current equalizer parameter is used as the lower limit value in the candidate equalizer parameter range. Similarly, if the voice response rate of the tested device is greater than the second response rate threshold, that is, the voice response rate condition is met, the gain of the equalizer parameter in the tested device at the low-frequency component is increased, so as to improve the THD of the loudspeaker at the low-frequency band, and reduce the echo cancellation processing effect of the AEC, until the obtained voice response is equal to the second response rate threshold, that is, when the voice response rate condition is about to be met and the voice response rate condition is not met, the current equalizer parameter is used as the upper limit value in the candidate equalizer parameter range. The first response rate threshold and the second response rate threshold may be the same, for example, both are 98%, in addition, the first response rate threshold and the second response rate threshold may also be different, and the first response rate threshold may be greater than the second response rate threshold. The lower and upper limits, in turn, constitute candidate equalizer parameter ranges and are associated with current candidate use distances.
In this embodiment, on the basis of the mapping relationship between the candidate use distance and the candidate equalizer parameter range, the target use distance of the device to be configured is compared with the candidate use distance, and the candidate equalizer parameter range associated with the candidate use distance closest to the target use distance is used as the target equalizer parameter range of the device to be configured. And then through choosing the parameter range of the goal equalizer from the mapping relation, can be under the prerequisite in order to meet the speech response rate of the intellectual device, namely guarantee the intellectual device can succeed the prerequisite of responding to user's speech control order, lock the adjustable range of the equalizer parameter in the parameter range of the goal equalizer, has reduced the adjustable range of the equalizer parameter in the intellectual device by a wide margin, raise parameter configuration efficiency and accuracy.
And S120, determining a target equalizer parameter value of the equipment to be configured in the target equalizer parameter range according to the audio playing characteristics of the equipment to be configured.
In an embodiment of the present invention, the audio playing feature is used to describe an audio playing effect of the device to be configured. The audio playing characteristics may include subjective indicators of sound quality such as volume, pitch, and timbre, and objective indicators of sound quality such as Frequency Response (FR) and harmonic distortion (THD) curves. The frequency response curve is used for describing the difference of the processing capacity of the equipment for signals with different frequencies electronically, and is a curve of the variation of gain along with frequency; the harmonic distortion curve refers to the harmonic cost of the output signal more than the input signal, and the harmonic distortion is caused by the fact that the system is not completely linear. The sum of all the additional harmonic levels is called total harmonic distortion, the total harmonic distortion is related to frequency, and further, a total harmonic distortion curve refers to a curve of the total harmonic distortion changing along with the frequency. The present implementation preferably uses objective features such as FR and THD to measure the audio playing characteristics of the device to be configured.
In this embodiment, the device to be configured is adjusted within the range of the target equalizer parameter, so as to obtain the audio playing characteristics of the device to be configured under each equalizer parameter, and according to the audio playing characteristics under each equalizer parameter, the equalizer parameter value with the best audio playing effect is selected as the target equalizer parameter value of the device to be configured.
Exemplarily, a frequency response curve and a harmonic distortion curve of a device to be configured when the device to be configured plays audio are obtained within a parameter range of a target equalizer; and determining the target equalizer parameter value of the equipment to be configured from the target equalizer parameter range according to the frequency response curve and the harmonic distortion curve. For example, the frequency response range of the frequency response curve at least covers the sound range which can be heard by human ears from 20Hz to 20KHz, and the flatter the frequency response curve is, the better the frequency response curve is; harmonic distortion is difficult to inhibit, the damage to tone quality is large, particularly odd harmonics are not musical, the damage to tone quality is great, and therefore the smaller the THD value is, the better the THD value is.
According to the technical scheme of the embodiment, the candidate equalizer parameter range associated with each candidate use distance is predetermined according to the voice response rate of the equipment, so that when the equalizer parameter configuration is performed on the equipment to be configured, the target equalizer parameter range of the equipment to be configured is determined according to the target use distance of the equipment to be configured and the mapping relation between the candidate use distance and the candidate equalizer parameter range, and the target equalizer parameter value of the equipment to be configured is determined in the target equalizer parameter range according to the audio playing characteristics of the equipment to be configured. According to the embodiment of the invention, by evaluating the voice response rate of the intelligent equipment, the audio playing effect of the equipment is improved on the premise of meeting the voice response rate, the sound effect of the intelligent equipment is ensured, and the voice response rate and the audio playing effect under the condition of internal noise reach the optimal balance point.
Example two
In this embodiment, on the basis of the first embodiment, a preferred implementation of the device configuration method is provided, and the candidate equalizer parameter range corresponding to the candidate use distance can be determined according to the voice response rate of the device in the candidate use distance. Fig. 2 is a flowchart of an apparatus configuration method according to a second embodiment of the present invention, and as shown in fig. 2, the method specifically includes the following steps:
and S210, if the reverberation time of the tested device under any candidate use distance exceeds the standard reverberation time range, ending the test of the equalizer parameter under the candidate use distance.
In the specific embodiment of the present invention, devices with the same model as various devices to be configured may be adopted as devices to be tested in advance, and the establishment of the mapping relationship between the candidate use distance and the candidate equalizer parameter range is realized by testing the value of the equalizer parameter range of the devices to be tested at different candidate use distances.
In this embodiment, the reverberation time is the time required for the sound pressure level to be reduced by 60dB through the attenuation process in the room after the sound source stops sounding. The reverberation time is too short, the sound is dry, and the sound is dry, tasteless and not close to nature; the reverberation time is too long, so that the sound is unclear; when the reverberation time is proper, the sound is mellow and smooth. Furthermore, when the mapping relationship between the candidate use distance and the candidate equalizer parameter range is established, the embodiment may select a reverberation room or other reverberation field condition for testing, so as to use the reverberation time as one of the conditions for adjusting the sound quality of the device. The reverberation time is an important evaluation index for the quantitative estimation of acoustic energy in acoustic design, and standard reverberation times applicable to different reverberation conditions are different. For example, the reverberation time suitable for movie presentations is typically no more than 0.8 seconds, and the reverberation time suitable for concert halls is typically 1.5 seconds.
In the available distance range of the equipment, a plurality of distances can be selected in advance to serve as candidate use distances respectively, and the distance between the tested equipment and the voice simulation sound source is fixed to serve as the candidate use distance. At each candidate use distance, the reverberation time of the reverberation chamber is recorded. And comparing the reverberation time under each candidate use distance with the standard reverberation time under the current reverberation condition, if the reverberation time under any candidate use distance exceeds the standard reverberation time range, rejecting the candidate use distance, and finishing the test of the equalizer parameters under the candidate use distance.
S220, in the process that the tested device plays the audio, determining the voice response rate of the tested device according to the response result of the tested device to the voice played by the voice simulation sound source and the voice playing times of the voice simulation sound source.
In the specific embodiment of the invention, the tested device is controlled to play white noise with the maximum volume, the voice simulation sound source is controlled to play voice commands with a certain frequency and times, the sound pressure level of the voice simulation sound source is adjusted to be standard sound pressure, such as 94dB, and the response result of the tested device to each voice command is determined. For example, assuming that a voice simulation sound source is controlled to play a voice control command 1000 times at a certain frequency, and the tested device is determined to successfully respond 980 times through detection of a response result, the voice response rate of the tested device under the current candidate use distance is calculated to be 98%.
And S230, determining the candidate equalizer parameter range of the tested device under the candidate using distance according to the voice response rate of the tested device.
In the specific embodiment of the invention, the candidate equalizer parameter range is determined according to the voice response rate of the tested device to the voice control instruction. The voice response rate is the ratio of the number of successful responses of the equipment to the total number of voice commands under the control of a certain number of voice commands. Based on the voice response rate condition, when the tested device crosses the critical point which meets and does not meet the voice response rate condition and the critical point which does not meet and meets the voice response rate condition, the upper and lower limit values of the equalizer parameter of the tested device are determined, so that the candidate equalizer parameter range of the tested device under the candidate use distance is obtained.
Optionally, if the voice response rate of the device under test is smaller than the first response rate threshold, the gain of the equalizer parameter in the low-frequency component is reduced until the obtained voice response rate is equal to the first response rate threshold, and the current equalizer parameter is used as a lower limit value in the candidate equalizer parameter range; if the voice response rate of the tested equipment is greater than the second response rate threshold value, the gain of the equalizer parameter in the low-frequency component is increased until the obtained voice response is equal to the second response rate threshold value, and the current equalizer parameter is used as an upper limit value in the candidate equalizer parameter range.
In this embodiment, the response rate threshold refers to a successful response rate condition required by the intelligent device of the tested device of the same type, for example, the response rate threshold of the intelligent sound box may be required to be 98%. The response rate may be a response success rate of the device for any voice control instruction, or may also be a response success rate of the device for a specific type or a certain voice control instruction, for example, an awakening rate of the device for a voice awakening word. In addition, the response rate threshold may be a single threshold, or may be a range of response rate thresholds, that is, the first response rate threshold and the second response rate threshold are included, and the first response rate threshold may be greater than the second response rate threshold.
In this embodiment, if the voice response rate of the device under test is less than the first response rate threshold, that is, the voice response rate condition is not satisfied, the gain of the equalizer parameter in the device under test at the low frequency component is reduced, for example, the gain of the frequency component of 50-300Hz is reduced, so as to reduce the THD of the loudspeaker at the low frequency band, and improve the echo cancellation processing effect of AEC, until the obtained voice response rate is equal to the first response rate threshold, that is, when the voice response rate condition is satisfied, the current equalizer parameter is used as the lower limit value in the candidate equalizer parameter range. Similarly, if the voice response rate of the tested device is greater than the second response rate threshold, that is, the voice response rate condition is met, the gain of the equalizer parameter in the tested device at the low-frequency component is increased, so as to improve the THD of the loudspeaker at the low-frequency band, and reduce the echo cancellation processing effect of the AEC, until the obtained voice response is equal to the second response rate threshold, that is, when the voice response rate condition is about to be met and the voice response rate condition is not met, the current equalizer parameter is used as the upper limit value in the candidate equalizer parameter range.
By way of example, FIG. 3 is an exemplary diagram of a parametric test system. As shown in fig. 3, under the condition of the reverberation field of the reverberation chamber, a human simulator and the like can be selected in advance as a voice simulation sound source, an intelligent device with the same model as that of the device to be configured is selected as a device to be tested for testing, and the distance between the device to be tested and the voice simulation sound source is fixedly set as a candidate use distance L. The sound pressure level of the voice analog sound source is tested by the PC and external test equipment such as a sound card, a power amplifier, an adapter and the like through a standard microphone, the adapter, the sound card and the PC, and the sound pressure level at the voice analog sound source is determined to be 94 dB. The equalizer curve is burned into the tested equipment through the PC, and the voice simulation sound source is controlled through the PC, the sound card and the power amplifier to play the voice command at a certain frequency and times, for example, 1000 times. And in the testing process, determining the response result of the tested device to each voice instruction, and calculating the voice response rate of the tested device under the current candidate using distance. And respectively determining the upper limit value and the lower limit value of the parameter under the current candidate use distance according to the voice response rate of the tested device under the current candidate use distance and the threshold value of the response rate as critical points, so as to obtain the parameter range of the candidate equalizer under the current candidate use distance.
S240, determining a target equalizer parameter range according to the target use distance of the equipment to be configured and the mapping relation between the candidate use distance and the candidate equalizer parameter range.
In the embodiment of the present invention, the target use distance of the device to be configured is compared with the candidate use distance, and the candidate equalizer parameter range associated with the candidate use distance closest to the target use distance may be used as the target equalizer parameter range of the device to be configured according to the comparison result.
And S250, acquiring a frequency response curve and a harmonic distortion curve when the equipment to be configured plays audio within the parameter range of the target equalizer.
In the specific embodiment of the invention, the device to be configured is adjusted within the parameter range of the target equalizer, and the device to be configured is controlled to play audio. FR and THD of the equipment to be configured during audio playing can be acquired through equipment such as an oscilloscope.
And S260, determining a target equalizer parameter value of the equipment to be configured from the target equalizer parameter range according to the frequency response curve and the harmonic distortion curve.
In the specific embodiment of the invention, the frequency response range of the frequency response curve at least covers the sound range which can be heard by human ears from 20Hz to 20KHz, and the flatter and straighter the frequency response curve is, the better; harmonic distortion is difficult to inhibit and has great harm to tone quality, particularly odd harmonics are non-musical and have great harm to tone quality, so that the smaller the value of THD is, the better the value is. Therefore, the target equalizer parameter value of the device to be configured can be determined from the target equalizer parameter range according to the shape of the curve based on FR and THD collected during the adjustment of the equalizer parameter of the device to be configured within the target equalizer parameter range. In addition, the tone quality of the voice signal heard manually can be obtained through artificial subjective listening, the person hearing the audio can input the heard tone quality into the PC, and the PC integrates objective indexes and subjective indexes to determine the target equalizer parameter value of the equipment to be configured from the target equalizer parameter range. Therefore, the best tone quality playing effect is obtained on the premise of ensuring the voice response rate.
