Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides a method for playing audio data, where the method is applied to a client, and as shown in fig. 1, the method includes:
101. the client acquires an operation instruction for adjusting the playing speed of the target audio.
It should be noted that the client according to the embodiment of the present invention may include, but is not limited to, the following contents, for example: the system comprises a book listening client, a video client, a music client and the like, wherein the clients need to be installed in terminal equipment, and the terminal equipment comprises a smart phone, a tablet computer, a personal computer and the like. The following description will be given by taking the client as a listening book client and the terminal device as a mobile phone, but it should be clear that the description is not intended to limit the specific types of the client and the terminal device.
When a user listens to audio through a book listening Application (APP) installed in a touch screen mobile phone and performs fast forward or slow down of the audio through operation on the touch screen, the user operates through a preset operation gesture on the user plane to realize fast play or slow down play of target audio. From the machine perspective, the client receives an operation instruction for adjusting the playing speed of the target audio sent to the client by a user through the touch screen, wherein the operation instruction comprises a to-be-adjusted interval of the target audio and the speed grade of the playing speed.
It should be noted that, in the embodiment of the present invention, when performing fast-forward playing or slow-down playing of a target audio, a to-be-adjusted interval included in an operation instruction may be only a part of the target audio, or may also be all the target audio, where the part is determined according to an actual requirement of a user, and a specific embodiment of the present invention is not limited. Whether the section to be adjusted of the adjustment target audio is partially adjusted or fully adjusted, the section to be adjusted comprises an adjustment starting point and an adjustment end point, and is a continuous section; for example, assuming that the total duration of the target audio is 60:00, when the target audio is played to 25:00, the speech rate is accelerated to play, and when the target audio is played to 31:00, the normal playing of the target audio is resumed, then the interval to be adjusted is: 25:00-31:00, wherein 25:00 of the target audio time length is an adjustment starting point, and 31:00 is an adjustment end point.
It should be noted that, when the to-be-adjusted interval in the operation instruction is acquired, an important point is to convert the operation of the user in the touch screen into the to-be-adjusted interval. Taking an operation instruction as a sliding operation as an example, when the user slides horizontally in the touch screen for a distance of M centimeters and turns into a section to be adjusted, the corresponding fast forward/slow playback time length is N minutes, and the like, the above description does not limit the type of the operation instruction and the operation limitation for adjusting the fast forward/slow playback of audio playing, but gives a description of the conversion relationship between the operation instruction and the section to be adjusted.
In the specific implementation process, the operation instruction and the speech rate level need to be configured in advance. The operation instruction may include, but is not limited to, a drag operation, a rotation operation, a multi-touch operation, a click operation, and the like; different operation instructions are different in the mode of converting the operation instructions into the intervals to be adjusted, and under the normal condition, the larger the relative displacement of the operation instructions in the touch screen is, the larger the corresponding interval to be adjusted is, the smaller the relative displacement of the operation instructions in the touch screen is, and the smaller the corresponding interval to be adjusted is; the speech rate level also comprises a plurality of levels, such as a first level, a second level and a third level; or, the lower the level value is, the lower the corresponding playing speed is; the larger the grade value is, the larger the playing speed is. Specifically, the embodiment of the present invention does not specifically limit the preset operation finger, the interval to be adjusted, and the speed level.
102. And the client adjusts the playing speed of speech of the target audio in the interval to be adjusted according to the speed of speech grade.
The audio playback speech rate is the number of words or the speed of the words played in a unit time, and for example, it is assumed that the number of broadcast words in normal audio playback is 300. The types of target audio are different, and the corresponding speech rates are also different.
In the embodiment of the invention, when the client plays the target audio quickly or slowly, the client is related to the speech speed grade information in the operation instruction. In a specific implementation process, the speech rate level may be a specific numerical value corresponding to a speech rate level, or may be a numerical range corresponding to a speech rate level. If the operation command is a drag operation command, the speech rate level can be determined by the speed of the drag, for example, if the drag speed is S1, the corresponding speech rate level is low, and if the drag speed is S2, the corresponding speech rate level is medium. If the operation instruction is a rotation operation instruction, the speech rate grade can be determined through the number of turns of rotation, and if the number of turns of rotation to the right is 2 turns, the quick-playing speech rate grade is a middle grade; if the left turn is 1 turn, the slow playback rate level is low. Specifically, the embodiment of the present invention does not limit the speed level.
And the client acquires a corresponding audio file from a path corresponding to the target audio, and adjusts the playing speed of the target audio in the interval to be adjusted according to the speed level. For example, assume that the normal playing speech rate of the target audio is 340 words/minute, and the playing time of the target audio is 00: in the interval to be adjusted of 00-15:00, when a user needs to slowly play the target audio, the client determines that the speech rate grade is high (220 characters/minute), and performs slow adjustment on the target audio in the interval to be adjusted according to the speech rate grade. The above description is only exemplary, and the embodiments of the present invention are not limited thereto.
103. And after the adjusted target audio is played, the client recovers the normal playing speed of the target audio.
Following the example of step 102, when the speech rate level is determined to be high (220 words/min), then the playback is slowed based on the adjusted target audio, i.e., the target audio is played at the playback speech rate of 220 words per minute from the adjustment start point in the interval to be adjusted of the target audio. It should be noted that, when the slow play of the target audio is performed, the embodiment of the present invention does not perform reverse play on the content that is originally played in the forward order, but refers to the slow play speed. When the target audio in the interval to be adjusted is played completely, the normal playing of the target audio is resumed, and when the user has a demand for fast forward or slow playback, the method shown in fig. 1 can be executed in a circulating manner until the target audio is played completely.
The audio data playing method provided by the embodiment of the invention obtains an operation instruction for adjusting the playing speed of the target audio, wherein the operation instruction comprises a to-be-adjusted interval of the target audio and the speed grade of the playing speed; adjusting the playing speed of the target audio in the interval to be adjusted according to the speed level; after the adjusted target audio is played, recovering the normal playing speed of the target audio; compared with the prior art, when the target audio is adjusted, the method and the device realize the adjustment by adjusting the playing speed in the interval to be adjusted instead of skipping the audio content in the fast forwarding or slow down process, so that the user can not only realize the fast forwarding or slow down of the target audio, but also know the brief description of the fast forwarding or slow down content.
At present, with the continuous development of terminal devices, terminals are more and more abundant, the embodiment of the present invention will be described by taking a terminal with a specific touch function and a terminal with a physical keyboard as examples, and for different operation objects, different identification methods need to be adopted when a client obtains an operation instruction for adjusting the playing speech rate of a target audio, and specifically include:
(1) and if the terminal is provided with a touch screen, acquiring an operation instruction for adjusting the playing speed of the target audio.
Firstly, a client displays a playing interface of a target audio based on the touch screen; monitoring the touch screen, and verifying whether an instruction triggered based on the touch screen is the operating instruction; and if the received instruction is an operation instruction, acquiring the operation instruction.
After the operation instruction is obtained, the displacement size and the displacement direction for triggering the operation instruction are obtained, wherein the displacement size is used for determining the length of the interval to be adjusted, and the displacement direction is used for indicating that the starting point of the interval to be determined is determined after the time length corresponding to the interval to be determined is determined.
It should be noted that, when determining the interval to be adjusted, the following manners may be adopted, but not limited to: calling a preset interface function, and determining the displacement size generated by the operation instruction, wherein the determined displacement size is a directed line segment from an initial position corresponding to the operation instruction to a final position corresponding to the operation instruction, and the length of the directed line segment is a numerical value, so that the displacement size needs to be converted into a time length related to the target audio. In the embodiment of the invention, when the interval to be adjusted is determined, firstly, the time length corresponding to the displacement size can be calculated according to the positive correlation between the displacement size and the length of the target audio progress bar; the length of the progress bar is used for representing the duration of the target audio; secondly, acquiring the current playing time of the target audio; and finally, determining the interval to be adjusted according to the current playing time of the target audio and the duration corresponding to the displacement.
In practical applications, the playing time lengths corresponding to different target audios may be different, but the length of the progress bar is kept constant, when the playing time length of the target audio is shorter, the percentage corresponding to the progress bar per minute is larger, and when the playing time length of the target audio is longer, the percentage corresponding to the progress bar per minute may be smaller. According to the embodiment of the invention, through the positive correlation between the displacement and the length of the target audio progress bar, the problem that the same interval to be adjusted occurs in different target audio durations on the premise of the same displacement in actual operation is ensured.
Before executing an operation instruction for adjusting the playing speed of the target audio, configuring the preset operation instruction, presetting a touch rule to map the operation instruction, and determining that the operation instruction triggered by a user is the operation instruction for fast playing or slow playing the target audio when the operation instruction received by the client is consistent with the preset operation instruction; and before the playing speed of the target audio is adjusted according to the speed grade, configuring the corresponding relation between the speed grade and the playing speed.
For example, as shown in table 1, table 1 shows a mapping relationship list between a preset operation instruction and a speech rate level according to an embodiment of the present invention, where the table illustrates a relationship between the preset operation instruction and the speech rate level when a target audio is played slowly or played quickly. Table 2 shows a mapping list of the speech rate levels and the number of words played, where the number of words broadcast per minute in table 2 is only an exemplary example, and is not intended to limit the normal speech rate of the target audio and the number of words after adjusting the speech rate. It should be noted that tables 1 and 2 are only exemplary examples, and the description form between the preset operation instruction, the speech rate level, and the number of words played in the embodiment of the present invention is not limited.
TABLE 1
TABLE 2
| Normal speech rate | Speech rate level 1 | Speech rate level 2 | Speech rate level 3 | Speech rate level 3 |
| 300 words/minute | 200 words/minute | 260 words/minute | 350 word/minute | 400 words/minute |
It is emphasized again that tables 1 and 2 are merely exemplary distances, and the distances of the speech rate levels shown in the tables are not meant to be specific limitations of the embodiments of the present invention, and in practical applications, there may be more speech rate levels, or fewer speech rate levels, and there may also be more or less speech rates of the target audio than 300 words/minute, and in particular, the embodiments of the present invention are not limited.
The embodiment of the present invention aims to fast forward or slow down a target audio by increasing or decreasing the speech rate of the target audio, and further understand the summary of the content during fast forward or slow down of the target audio, so the following will describe in detail the playing of the target video in a section to be adjusted. As shown in fig. 2, fig. 2 is a schematic diagram illustrating a displacement direction generated by an operation instruction according to an embodiment of the present invention; taking an operation instruction as an example of dragging, point a is a starting point of a user operation, and in the first case: when the user performs the dragging from a to B (L3), the displacement direction generated by the corresponding operation instruction is rightward, in this case, the target audio in the interval to be adjusted is played according to the speech rate level with the second time point (the current playing time of the target audio) as the playing starting point. In the second case: when the user performs the drag operations a to E (L4), the generated displacement direction is not parallel to the progress bar, in which case the default is the user's right drag operation, i.e. as shown in fig. 2, a vertical line of the AB line segment is made, and the displacement direction pointing to the right side of the vertical line is determined as the displacement direction of the operation instruction being the right side.
Similarly, in the third case, when the user performs the dragging from a to C (L1), the line segment AC is located on the left side of the vertical line, and the direction of the displacement from a to C is determined to be left, in this case, after playing the audio of the plaque, the target audio in the interval to be adjusted is played according to the speech rate level with a first time point as a playing starting point, where the first time point is a time point obtained by subtracting a duration corresponding to the displacement from the current playing time. For convenience of understanding, it is assumed that, for example, the interval to be adjusted, which is determined by the above method according to the time length corresponding to the displacement size, is 10min at the point a (the current target audio playing time is 50:00), and then, when the target audio playing is performed, the target audio is played from 40:00 of the target audio in combination with the speech rate level of the playing speech rate determined by the above method. The above are merely exemplary, and specific numerical values are not limited.
The above embodiment is described by taking an example in which the operation instruction is triggered by a drag method, and the following description will be given by taking an example in which the operation instruction is triggered by a rotation operation. For example, as shown in fig. 3, fig. 3 shows an operation schematic diagram of a user in a terminal touch screen according to an embodiment of the present invention, when a playing interface of a target audio is displayed in a current screen, a client monitors an operation instruction, the client obtains a rotation direction included in the operation instruction by 2 turns, and the rotation direction is rightward, so that a speech rate level 2 for adjusting a playing speech rate of the target audio in a to-be-adjusted interval L can be determined, and the playing of the target audio can be executed from a current playing time.
The two-point touch operation is also briefly described. Illustratively, as shown in fig. 4, a user operates the touch screen by two fingers, wherein one finger is located at point a, point a is fixed, and from the point a adjacent to the other finger, the other finger slides to point B in parallel to the right, and the client acquires that the displacement between point a and point B corresponding to the operation instruction is L1, so that the interval to be adjusted T1 corresponding to L1 can be determined, and the sliding speed is V1, so that the target audio in the interval to be adjusted T1 is played according to the speech rate level corresponding to V1 from the current playing time point.
In practical applications, when the preset operation instruction is a shake terminal operation, the preset condition of shake needs to be limited, which is used for distinguishing accidental shake from shake motion intended by the user, or can also be used for distinguishing shake motion for other operation functions from shake motion for data acquisition in the embodiment. The preset operation instruction condition may be set by the user through shaking of the mobile phone in the setting stage, for example, the preset condition may be set to "shake once", "shake twice" or "shake three times" or the like.
In practical application, when the terminal shakes, the terminal can monitor shaking actions through the motion sensor, the motion sensor can be but is not limited to a gravity acceleration sensor, and when the mobile phone shakes, the sensor can detect the generation of acceleration and can obtain the direction of the acceleration. When the preset conditions are set, the mobile phone can set the preset conditions according to shaking data (whether acceleration is generated, the magnitude and direction of the acceleration and the like) returned by the sensor. In a feasible scheme of this embodiment, since the gravitational acceleration sensor can detect not only whether the gravitational acceleration is generated, but also the magnitude of the gravitational acceleration, the mobile phone can also distinguish the intensity of the shaking of the user according to the obtained specific shaking data, thereby enriching the number of shaking instructions. Generally, the gravity acceleration generated by a user shaking the mobile phone lightly is smaller than that generated by shaking the mobile phone vigorously, when a preset operation instruction is set, the mobile phone can divide the magnitude of the gravity acceleration into intervals, the user is allowed to set the shaking action of the preset operation instruction to be stronger, and the shaking action of the other function is set to be weaker, so that two different operations are distinguished. Along with the continuous increase of the functions of the mobile phone, limited shaking operation types cannot meet the increasing functions, in the scheme, the mobile phone can develop a new method in the dimension of the gravity acceleration (the strength of shaking in the user using layer) and combines the existing shaking operation to expand the quantity of the shaking operation in multiples, so that the operation mode of the mobile phone is enriched.
In practical application, when a user selects a terminal or an application program, consideration of selection also depends on the use experience and convenience of the user, and the application program can be operated by presetting an operation instruction (an operation instruction triggered by a gesture instruction) in the embodiment, so that the diversity of operation can be enhanced, and the use experience of the user is enhanced.
(2) And the specific physical keyboard of the terminal acquires an operation instruction for adjusting the playing speed of the target audio.
When the target audio is played in the terminal, monitoring a physical keyboard in the terminal, and receiving an operation instruction for adjusting the playing speed triggered based on the physical key; matching the operation instruction with a preset operation instruction; and if the operation instruction is consistent with the preset operation instruction, acquiring the operation instruction.
Before executing the operation instruction for adjusting the playing speech rate of the target audio, one or more physical keys may be preset as the triggered operation instruction, and taking preset one physical key as an example, a power key, a confirmation key or an external key may be preset as the preset operation instruction. The speech rate grade corresponding to the preset operation instruction can also be determined by the duration of triggering the physical key. For example, the duration of triggering the physical key may be set to 2 seconds corresponding to the speech rate level 1, the duration of triggering the physical key may be set to 4 seconds corresponding to the speech rate level 2, the duration of triggering the physical key may be set to 5 seconds corresponding to the speech rate level 3, and the like.
In addition, the client may also obtain the operation instruction based on various sensors built in or external to the terminal, for example, a microphone, and the like.
In an implementation manner of this embodiment, the terminal may collect an acoustic signal sent by the user through the microphone, and when the user sends a preset voice instruction (for example, some keywords), the terminal obtains the operation instruction and sends the operation instruction to the client. The preset voice command can be set by the user according to the preference of the user, and for example, the user can set the voice command to be "fast forward one level", "slow down one level", and the like. The present embodiment does not limit the carrying form and the obtaining manner of the operation instruction.
In another embodiment of the present invention, the client may further monitor a light sensor built in the terminal, and a light sensor is generally disposed on the front of the terminal near the earpiece, and is used to detect the intensity of ambient light outside the terminal, so as to adjust the screen brightness. In this embodiment, the mobile phone may recognize the operation gesture of the user by using the light sensor, and when the user slides across the terminal screen with a palm or covers the mobile phone screen, the terminal recognizes that the external light intensity is smaller than the preset brightness threshold, so as to obtain the operation instruction, and sends the operation instruction to the client.
Further, as an implementation of the method shown in fig. 1, another embodiment of the present invention further provides an apparatus for playing audio data. The embodiment of the apparatus corresponds to the embodiment of the method, and for convenience of reading, details in the embodiment of the apparatus are not repeated one by one, but it should be clear that the apparatus in the embodiment can correspondingly implement all the contents in the embodiment of the method.
