And default corresponding relation between erasing time and voice data quantity can also according to demand before this step, or
Set before either step before this step, this embodiment of the present application is not also limited.
For example, it is assumed that Preset Time unit is one day, for example, preserve working as to target storage domain in the first voice data A
It only saves the first voice data A.Assuming that default ratio between erasing time and voice data quantity is 5:1, then this
When first voice data A default erasing time be at the end of the 5th day after it is stored in the domain of target storage；And
If also saving 4 audios, voice data now in addition on the day of the first voice data A is preserved to target storage domain
Quantity is 5, then now the default erasing time of first voice data A is after it is stored in the domain of target storage
At the end of 25th day.
In addition, default relation not necessarily proportional relation between erasing time and voice data quantity, or
Linear relationship etc. other proportionate relationships.For example, it is assumed that default erasing time is y, voice data quantity is x, then y can be
X*x, or 3x+1, etc..
Step 280, when default erasing time is reached, first voice data is deleted from the target storage domain
Remove.
In the embodiment of the present application, when the decoding to the target audio data for having cached is completed, the target sound is obtained
Frequency is according to corresponding decoding data；The decoding data is recompiled using default coded system, obtains the first sound
Frequency evidence；First voice data is preserved to the local target storage domain of the mobile terminal；When reaching default deletion
