Detailed Description
The scheme provided by the specification is described below with reference to the accompanying drawings.
Fig. 1 is a schematic view of an implementation scenario of an embodiment disclosed in this specification. The implementation scenario relates to volume adjustment of a voice broadcast device. It is understood that the voice broadcasting device may be any device having a voice broadcasting function, and in addition to the voice broadcasting function, the device may have, but not limited to, additional functions such as communication, video playing or payment, for example, a mobile phone, a television, a radio, a payment device, and the like. Due to the usage habits of the user, the voice broadcasting device may be set to mute or adjust the volume to a very small volume value so that the user cannot hear the broadcasting of important voice. Fig. 1 shows a typical payment scenario in which a user completes a transaction by using a merchant-side device 11 and a user-side device 12, where the merchant-side device 11 is an internet of things (IoT) related device with a payment function, called payment device for short, and the payment device can guide the user to quickly complete a payment operation by accessing a voice broadcast function, such as prompting to scan a code, swiping a face, confirming a password, confirming a payment result with a cashier, and the like; under the mute condition of the payment equipment, the loss of voice prompt ensures that a cashier and a user cannot perceive the payment condition, the communication cost is easily increased, the cash registering efficiency is reduced, and even the money loss caused by bill missing appears. And if the payment device is forced to be silent, the cash register is inconvenient to use and even daily life is affected.
According to the embodiment of the specification, the volume of the voice broadcasting equipment is adjusted according to the importance of the audio content to be broadcasted, the use habits of users can be considered, and important voice broadcasting is achieved.
Fig. 2 is a flowchart illustrating a volume adjustment method of a voice broadcasting device according to an embodiment, which may be based on the implementation scenario illustrated in fig. 1. As shown in fig. 2, the volume adjusting method of the voice broadcasting device in this embodiment includes the following steps: step 21, the voice broadcasting equipment determines that a first voice prompt tone needs to be broadcasted; step 22, the voice broadcasting equipment judges whether a first condition and a second condition are met; the first condition is that the importance of the first voice prompt tone is higher than a preset level, and the second condition is that the current volume is in a mute state or the current volume is smaller than a preset threshold; step 23, if the voice broadcasting device judges that the first condition and the second condition are met, adjusting the volume to be a target volume based on the current environmental noise; and step 24, the voice broadcasting equipment broadcasts the first voice prompt tone according to the target volume. Specific execution modes of the above steps are described below.
First, in step 21, the voice broadcasting device determines that a first voice prompt tone needs to be broadcasted. It can be understood that, if the voice broadcast device is a payment device, step 21 may specifically occur when a transaction is started, or during a transaction, or after a transaction is completed.
If the voice broadcast equipment is payment equipment, wherein, the concrete broadcast content of above-mentioned first voice prompt tone may be strongly relevant with payment, also may not be strongly relevant with payment, for example, first voice prompt tone may be for scanning code prompt tone, input password prompt tone after sweeping the code by a large amount, pay failure prompt tone etc. and pay strongly relevant broadcast content, first voice prompt tone may also be for greeting, finish, advertisement etc. and pay non-strongly relevant broadcast content.
In one example, the payment device executes a first transaction associated with a target user, and when the first transaction is not completed, determines that a first voice prompt tone needs to be broadcast; alternatively, the first and second electrodes may be,
the payment device executes a first transaction associated with a target user, and determines that a first voice prompt tone needs to be broadcast after the first transaction is completed.
After the transaction is completed, voice prompt tones can be broadcasted for prompting the amount of the account, or reminding the merchant of successful payment.
It should be noted that the voice broadcasting device may be, but is not limited to, a payment device, and accordingly, the time for broadcasting the first voice prompt tone and the content of the first voice prompt tone are widely covered, for example, the voice broadcasting device is a navigation device, and can determine that the first voice prompt tone needs to be broadcast in the navigation process, and the first voice prompt tone is used for reminding a traffic jam ahead; or the voice broadcasting equipment is a television, and a first voice prompt tone can be determined to be broadcasted in a starting or standby state, wherein the first voice prompt tone is used for reminding a tsunami or an emergency such as an earthquake.
Then, in step 22, the voice broadcasting device judges whether a first condition and a second condition are satisfied; the first condition is that the importance of the first voice prompt tone is higher than a preset level, and the second condition is that the current volume is in a mute state or the current volume is smaller than a preset threshold. It can be understood that the voice broadcast device determines whether the first condition and the second condition are satisfied at the same time, and as long as one condition is not satisfied, the voice broadcast device is regarded as not satisfying the first condition and the second condition.
In one example, the voice broadcasting device may first determine whether a first condition is satisfied, and when the first condition is satisfied, then determine whether a second condition is satisfied; when the first condition is not satisfied, it is not necessary to judge whether the second condition is satisfied.
For the first condition, it can be understood that, according to different broadcast contents, various voice prompt tones can be divided into at least two levels in advance, and the voice prompt tones of different levels correspond to different importance.
In one example, the voice broadcast device is a payment device; the importance of the voice prompt tone strongly related to payment is preset to correspond to a first grade, the importance of the voice prompt tone not strongly related to payment is preset to correspond to a second grade, and the first grade is higher than the second grade. Based on this example, step 22 specifically includes: and the payment equipment judges whether the importance of the first voice prompt tone is higher than the second grade or not, and determines that the first condition is met when the importance of the first voice prompt tone is judged to be higher than the second grade. That is, it is determined whether the importance of the first voice prompt is the first level to determine whether a first condition is satisfied.
In the example, through the judgment of relevance between the voice prompt tone and the payment operation, the broadcasting of the important voice prompt tone under the condition of equipment silence or small volume is realized, the blockage of the payment link caused by no voice prompt or small volume is avoided, and the cash registering efficiency is improved.
In one example, if the voice broadcasting device determines that the first condition is not satisfied, the first voice prompt tone is broadcasted at the current volume.
For the second condition, it can be understood that if the current volume is in a mute state or the volume is small, it indicates that the subjective intention of the user may not wish to perform voice broadcast; if the current volume is not in a mute state or the volume is larger, the fact that the user's subjective intention may want to perform voice broadcasting is indicated.
In the embodiment of the present specification, the preset threshold may be set to a smaller volume value, and when the volume is lower than the preset threshold, effective broadcast of the voice prompt tone cannot be realized.
In one example, if the voice broadcasting device determines that the second condition is not satisfied, the first voice prompt tone is broadcasted at the current volume.
Next, in step 23, if the voice broadcast device determines that the first condition and the second condition are satisfied, the volume is adjusted to the target volume based on the current environmental noise. It is understood that the decibel value of the ambient noise is dynamically changing, and sometimes the decibel value of the ambient noise is high, such as when people crowd; sometimes the decibel value of the ambient noise is low, e.g., quiet. The volume is adjusted to be the target volume based on the current environmental noise, so that the target volume is more reasonable and meets the user requirements in different environments.
In one example, the adjusting the volume to a target volume based on the current ambient noise includes:
acquiring current environmental noise;
determining a target difference value according to a historical difference value of the historical volume and the historical environmental noise;
and adjusting the volume to be the target volume according to the current environmental noise and the target difference value.
It can be understood that the payment device may collect the current environmental noise through the microphone to obtain a decibel value of the current environmental noise. In the embodiments of the present specification, the decibel value of the current environmental noise is simply referred to as the current environmental noise.
Further, the determining a target difference value according to the historical difference value between the historical volume and the historical environmental noise includes:
acquiring various pre-stored historical differences of historical volume and historical environmental noise and service time corresponding to the historical differences respectively;
and selecting the history difference with the longest use time from the history differences as a target difference.
The following explains how to select the target difference value by way of example, referring to the table of correspondence between each history difference value and the usage time shown in table one.
Table one: corresponding relation table of each historical difference value and service time
| Historical difference | Time of use |
| D1 | Ten months old |
| D2 | One month |
| D3 | Three days |
As can be seen from table one, the usage time corresponding to the history difference D1 is ten months, the usage time corresponding to the history difference D2 is one month, and the usage time corresponding to the history difference D3 is three days, where the usage time corresponding to the history difference D1 is the longest, and therefore the history difference D1 is selected as the target difference.
Further, the history difference is stored when the user manually changes the volume, and the usage time may be determined according to a time interval between two changes of the volume. That is, when the user manually changes the volume, the difference D = X-Y (decibel) between the current system volume X (decibel) and the environmental noise Y (decibel) is saved.
Further, in another example, the determining a target difference value according to a historical difference value of the historical volume and the historical environmental noise includes:
acquiring various pre-stored historical differences of historical volume and historical environmental noise and updating moments corresponding to the historical differences respectively;
and selecting the history difference value which is closest to the current time at the updating time as a target difference value from the history difference values.
How to select the target difference is described below by way of example, see the table of correspondence between the history differences and the update time shown in table two.
Table two: corresponding relation table of each historical difference value and updating time
| Historical difference | Update time of day |
| D1 | 35 points on 1/10/2019 |
| D2 | 13 o 20 points in 12, 15 and 2019 |
| D3 | 8 o' clock 18 points on 1 month and 1 day of 2020 |
As can be seen from table two, the update time corresponding to the historical difference D1 is 35 points at 9 points on 1/10/15/2019, the update time corresponding to the historical difference D2 is 20 points at 13 points on 15/12/2019, and the update time corresponding to the historical difference D3 is 18 points at 8 points on 1/2020, wherein the update time corresponding to the historical difference D3 is closest to the current time, and therefore the historical difference D3 is selected as the target difference.
Further, the history difference is stored when the user manually changes the volume, and the update time may be determined according to the stored time.
Further, the adjusting the volume to a target volume according to the current environmental noise and the target difference value includes:
summing the current environmental noise and the target difference value to obtain initial volume;
if the initial volume is between the preset volume minimum value and volume maximum value, determining the initial volume as the target volume;
if the initial volume is smaller than the minimum volume, determining the minimum volume as the target volume;
if the initial volume is larger than the maximum volume, determining the maximum volume as the target volume;
and adjusting the volume to the target volume.
For example, the adjustable volume range is preset to [ D _ min, D _ max ] db. And obtaining the current environmental noise E decibel, wherein the target volume is E + D1 decibels. If D _ min < = E + D1< = D _ max, adjusting the volume to E + D1 decibels; if E + D1< D _ min, adjusting the volume to D _ min decibel; if E + D1> D _ max, the volume is adjusted to D _ max decibels.
In the embodiment of the specification, the range of the adjustable volume is preset, so that the damage of the adjusted volume to human ears can be avoided. Moreover, when the volume is adjusted, the habit of the user and the environmental noise are comprehensively considered, the volume is adjusted more reasonably, the negative emotion brought to the user by too large volume in a quiet environment is avoided, and the problem that the too small volume does not play a role in prompting in a noisy environment is solved.
And finally, in step 24, the voice broadcasting equipment broadcasts the first voice prompt tone according to the target volume. It will be appreciated that different voice prompts may be broadcast at different volumes.
In one example, if the voice broadcasting device determines that the first condition and the second condition are met, recording a first volume value of a current volume, and then adjusting the volume to a target volume based on a current environmental noise; after the voice broadcast equipment broadcasts the first voice prompt tone with the target volume, the voice broadcast equipment resets the volume to the first volume value.
It will be appreciated that when in a mute state, a first volume value of 0 may be recorded to mark the mute state.
This example gives the volume control right to the user of the voice broadcast device (e.g., a cashier using the payment device), and in a silent state or at a small volume, ensures the broadcast of important prompt tones, for example, improves the fluency of the payment link in the payment scene, and after the broadcast is completed, resets the volume to the silent state, thereby ensuring the volume control right of the user.
According to the method provided by the embodiment of the specification, firstly, the voice broadcasting equipment determines that a first voice prompt tone needs to be broadcasted; then, the voice broadcasting equipment does not directly broadcast the first voice prompt tone at the current volume, but firstly judges whether a first condition and a second condition are met; the first condition is that the importance of the first voice prompt tone is higher than a preset level, and the second condition is that the current volume is in a mute state or the current volume is smaller than a preset threshold; if the voice broadcasting equipment judges that the first condition and the second condition are met, adjusting the volume to be a target volume based on the current environmental noise; and finally, the voice broadcasting equipment broadcasts the first voice prompt tone according to the target volume. It is thus clear that this specification embodiment, based on the importance and the current volume of first voice prompt tone, the volume of intelligent regulation voice broadcast equipment to can compromise user's use habit, and realize the report of important pronunciation.
