Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
Various embodiments of the method of the present invention are proposed based on the above-mentioned mobile terminal hardware structure.
Fig. 2 is a flowchart of a method for implementing voice information processing according to an embodiment of the present invention, as shown in fig. 2, including:
step 200, judging whether the initial residual electric quantity of the terminal meets the playing of the voice information within the normal playing time length;
it should be noted that the normal playing duration of the voice information can be obtained from the attribute of the voice information, and can also be obtained by reading the parameters in the play list through the voice player; for example, the normal play time length of the voice information can be obtained from the detailed information in the attribute of the voice information. In addition, the first time rectangular method can be determined by adopting the power management function of the system according to the residual power of the terminal and the power consumption condition during the voice playing statistics; and the power consumption can be determined according to the residual power of the terminal and the power consumption condition during voice playing statistics according to the power management application. When compressing the voice information according to the first voice compression rate, in order to complete the playing of the compressed voice information within the first duration, the size of the first voice compression rate is generally adjusted appropriately to ensure that the compressed voice information completes the playing within the first duration.
Step 201, when the initial remaining capacity of the terminal cannot meet the playing of the voice information within the normal playing time, determining a first time length for which the initial remaining capacity can be used for the playing of the voice information;
step 202, determining a first voice compression rate according to the determined first time length, and compressing voice information according to the first voice compression rate;
the first voice compression rate is inversely proportional to the playing time length of the compressed voice information, and the playing time length of the compressed voice information is less than or equal to the first time length.
It should be noted that the playing duration of the compressed voice information is equal to the first duration, and the playing of the compressed voice information can be satisfied according to the current judgment; the playing duration of the compressed voice information is less than the first duration, so that the influence of other power consumption of the terminal on the playing of the compressed voice information can be avoided, for example, the user performs information sending operation on the terminal to cause extra power consumption of the terminal; or reserving a certain amount of electricity for the user to reply after listening to the compressed voice message.
Optionally, the playing the voice information compressed according to the first voice compression rate includes:
dividing the compressed voice information into preset number of voice fragments;
and playing all the divided voice segments one by one according to the time of the voice information of each voice segment after being compressed.
It should be noted that the method for dividing the voice segments may be a conventional method for dividing the audio information; for example, a timestamp of the compressed voice information is acquired, and the compressed voice information is divided according to the timestamp; when the voice time is divided, the compressed voice information can be divided into a preset number of voice segments according to the time stamp and in a time averaging mode; the preset number can be two or more, and the general preset number can be 2-8; the method can be properly adjusted according to the residual electric quantity of the terminal and the normal playing time of the voice information; generally, the preset number is in direct proportion to the residual electric quantity of the terminal and the normal playing time of the voice information; namely, when the residual electric quantity of the terminal is more, the numerical values of the preset number can be correspondingly larger; when the voice information is normally played for a long time, the preset number of values can be correspondingly larger. The number of the voice segments in the embodiment of the present invention may be determined by receiving information set by a user through an interactive interface, fig. 3 is a schematic diagram of a numerical value of a preset number of voice segments in the embodiment of the present invention, as shown in fig. 3, a corresponding numerical value may be selected by scrolling a scroll bar up and down, the scroll bar may be implemented by physical keys selected up and down, or the selection of a numerical value may be implemented by directly fluctuating numbers on a touch screen.
Step 203, playing the voice information compressed according to the first voice compression rate.
The method of the embodiment of the invention also comprises the following steps:
when the voice segments are played one by one, monitoring the real-time residual electric quantity of the terminal in real time;
determining a second time length which can be used for playing the voice clip according to the monitored real-time residual electric quantity;
when the playing of the voice segments which are not played can not be completed within the second time length, the voice compression rate of the voice segments which are not played at all is adjusted according to the determined second time length and a preset voice compression strategy;
and compressing the voice segments which are not played at all according to the adjusted voice compression rate.
It should be noted that adjusting the voice compression rate of the voice segment does not affect the playing process and playing rate of the voice segment, and the voice segment continues to be played according to the original sequence.
In addition, the voice segments which are not played comprise voice segments which are not played at all and voice segments which are played with partial contents, namely, the voice segments which are played with partial contents do not need to be compressed according to the adjusted voice compression rate, and only the playing needs to be finished continuously.
Optionally, adjusting the voice compression rate of the voice segment that is not played at all includes:
determining the unplayed time length of the currently played voice clip, and subtracting the determined unplayed time length of the currently played voice clip from the second time length to obtain a third time length;
determining a second voice compression rate of all voice segments which are not played completely according to the determined third duration;
and the playing time length of all the voice fragments which are not played at all and compressed according to the second voice compression rate is less than or equal to the third time length.
It should be noted that, in the embodiment of the present invention, when a voice clip is being played, a voice clip that is not played at all is compressed, so that a pause caused by compression when a voice clip that is not played at all needs to be played is avoided, and uninterrupted connection of voice clips is realized.
Optionally, adjusting the voice compression rate of the voice segment that is not played at all includes:
determining the unplayed time length of the currently played voice clip, and subtracting the determined unplayed time length of the currently played voice clip from the second time length to obtain a third time length;
and determining the segment compression rate corresponding to each completely unplayed voice segment according to the determined third duration.
It should be noted that, after the third duration is determined, the compression rates of the voice segments that are not played at all may be determined one by one in the embodiment of the present invention; in order to realize natural connection of voice information, the compression rate can be determined according to a piecewise function; or, when there are many voice segments not played at all, for example, more than three, the segment compression rate of the piecewise function is adopted by a plurality of segments closest to the time of the voice segment currently being played; after the connection transition is completed, compressing the subsequent completely unplayed segments according to the same segment compression rate; the value of the segment compression rate may be set with reference to a second speech compression rate, for example, a first speech segment that is later than a currently playing speech segment, where the segment compression rate is greater than the second speech compression rate by a first preset percentage; the second voice segment which is backward from the voice segment currently being played has a segment compression rate which is greater than the second voice compression rate by a second preset percentage; the fourth voice segment which is played at present and is backward, the segment compression rate is the same as the second voice compression rate; the segment compression rate of the fourth voice segment which is backward from the voice segment currently being played is smaller than the second voice compression rate by a second preset percentage; the first preset percentage may be twice the second preset percentage; after the segment compression rate is determined, the time length for playing the segment which is not played at all can be calculated, and the time length is less than or equal to the third time length.
The embodiment of the invention can select the second voice compression rate to compress the voice segments which are not played completely according to the user setting, or select each voice segment which is not played completely to contain the corresponding segment compression rate according to the user setting, and when each voice segment which is not played completely contains the corresponding segment compression rate, a segment function of the default segment compression rate can be set; fig. 4 is an interaction diagram illustrating the selection and adjustment of the compression rate for the completely unplayed segment according to the embodiment of the present invention, and as shown in fig. 4, when the user determines the selection of the boolean key through the physical key or the touch key, it determines whether to compress the completely unplayed voice segment at the second voice compression rate or to select each completely unplayed voice segment to include a corresponding segment compression rate. Besides the segment function of the default segment compression rate, the embodiment of the invention can select the segment functions of other segment compression rates by means of a scroll bar or a confirmation option; fig. 5 is an interaction diagram of a piecewise function for selecting a segment compression rate according to an embodiment of the present invention, and as shown in fig. 5, a default piecewise function 1 that can be set by default according to an embodiment of the present invention is: according to the sequencing of voice fragments which are not played at all, setting fragment compression rates which are continuously reduced according to a third preset percentage one by one; the optional piecewise function 2 is: selecting the two voice fragments at the top according to the sequence of the voice fragments which are not played completely, setting the fragment compression rates of the two selected voice fragments one by one according to a fourth preset percentage, wherein the compression rates of other subsequent fragments are the same as the fragment compression rate of the second selected voice fragment; the optional piecewise function 3 is: and setting the segment compression rate of each completely unplayed voice segment according to user definition.
Fig. 6 is a flowchart of a method for implementing voice information processing according to an embodiment of the present invention, as shown in fig. 6, including:
