Abstract
The invention relates to a method for judging whether a mobile terminal has call voices after call connection. The method comprises the following steps of: S1, starting voice recording and timing by a system when a call of the mobile terminal is connected; S2, taking waveform data of the call voices, and temporarily storing the waveform data in the memory of the mobile terminal; S3, filtering noises; and S4, if mute waveform data is acquired, determining that the two parties have no call, and when the time starting from the beginning of the call reaches M minutes, starting a prompting module, otherwise, ending the judging, and returning to the normal procedure. By implementing the method, an error dialing or a wrong call can be interrupted in time, thereby avoiding electric energy and telephone expense wastes, and providing convenience for use by users.
Description
Technical field
The present invention relates to moving communicating field, more particularly, relate to a kind of method that has or not call voice after mobile terminal call is connected of judging.
Background technology
In the last few years, development along with mobile communication technology, portable terminal has obtained popularizing widely, and especially touch-screen mobile phone has obtained consumer's favor especially, but no matter is dull and stereotyped mobile phone or touch-screen mobile phone, there is the problem that mistake is dialled in the capital, when the mobile phone mistake has been dialled phone, the especially phone of automatic answering machine system, if the user is ignorant, not only consume the electric weight of mobile phone but also the telephone expenses of user's waste, cause unnecessary loss to the user.
Summary of the invention
The technical problem to be solved in the present invention is, at the above-mentioned defective of prior art, provides a kind of method that has or not call voice after mobile terminal call is connected of judging.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method that has or not call voice after mobile terminal call is connected of judging is provided, and described method may further comprise the steps:
S1, mobile terminal call are connected, and system begins recording and timing;
S2, get the Wave data of call voice, be temporary in the portable terminal internal memory;
S3, filtered noise;
If S4 obtains quiet Wave data,, when reaching M minute, then start reminding module from the conversation timing then for both sides do not have conversation; Otherwise, then finish to judge, return normal flow.
More specifically, above-described a kind of method that has or not call voice after mobile terminal call is connected of judging, described reminding module shows as language and characters prompting, vibration prompt or cuts off phone by force.
More specifically, above-described a kind of method that has or not call voice after mobile terminal call is connected of judging judges that Wave data is that quiet method is, when the mean value of the amplitude of waveform during less than specific threshold values, does not then have the quiet of conversation for both sides.
More specifically, above-described a kind of method that has or not call voice after mobile terminal call is connected of judging judges that Wave data is that quiet method is, when the degree of approximation of waveform reaches specific threshold values, does not then have the quiet of conversation for both sides.
Implement a kind of method that has or not call voice after mobile terminal call is connected of judging of the present invention, have following beneficial effect:
Implement the present invention and can in time interrupt dialling or wrong conversation by mistake, avoid waste electric energy and telephone expenses, user-friendly.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
To be that the present invention is a kind of judge the method program process flow diagram that has or not call voice after mobile terminal call is connected to Fig. 1;
Fig. 2 is a kind of oscillogram of judging common conversation sound among the method embodiment that has or not call voice after mobile terminal call is connected of the present invention;
To be that the present invention is a kind of judge the oscillogram when quiet among the method embodiment that has or not call voice after mobile terminal call is connected to Fig. 3;
To be that the present invention is a kind of judge the embodiment wave test synoptic diagram that has or not the method for call voice after mobile terminal call is connected to Fig. 4.
Embodiment
As shown in Figure 1, in a kind of embodiment that judges the method that has or not call voice after mobile terminal call is connected of the present invention, described method may further comprise the steps:
S1, mobile terminal call are connected, and system begins recording and timing;
S2, get the Wave data of call voice, be temporary in the portable terminal internal memory;
S3, filtered noise;
If S4 obtains quiet Wave data,, when reaching M minute, then start reminding module from the conversation timing then for both sides do not have conversation; Reminding module shows as language and characters prompting, vibration prompt or cuts off phone by force.Otherwise, then finish to judge, return normal flow.Described time period M minute, can be by default.
Behind the filtered noise, as shown in Figures 2 and 3, transverse axis T express time among Fig. 3, longitudinal axis ∮ represents amplitude, in normal conversation, voice just differ, voice amplitude also height differs, and when quiet, the mean value of amplitude can reach certain amplitude, the mean value of amplitude can be less than a threshold values, so the mean value of available amplitude is done a judgement.When the mean value of the amplitude of waveform during less than specific threshold values, being both sides does not have the quiet of conversation.
The quiet method of another kind of judgement is, as Fig. 4, the transverse axis express time, the longitudinal axis is represented amplitude, behind the filtering noise, detect sound waveform, the time span of each detection waveform is T (being predefined for 60 seconds), S1-S2, S3-S4, the S5-S6 time period, duration is T, detects 1 time every T1 (setting 300 milliseconds).The time interval between the S1-S3 is T1, the time interval between the S3-S5 is T1, if detect once every T1, detect the T duration, S1-S2, S3-S4, the waveform degree of approximation of S5-S6 reaches certain threshold values X (being preset as 85%), and the total duration that detects reaches M minute of setting, and then can be judged as is that both sides do not have the quiet of conversation, otherwise is common conversation.
Analog digital conversion of the present invention is realized by mobile terminal chip, because at present a lot of mobile phone all has sound-recording function, for example records into amr file or wav file, so the present invention need not to increase hardware cost.
In sum, as those of ordinary skill is scrutable in the art, described in this instructions is a preferred embodiment of the present invention, and all changes of being made under this invention's idea or modification all should be in claim protection domains of the present invention.
