Embodiment
Fig. 1 is the process flow diagram of the first embodiment of a kind of method of filtering call noise of the present invention.In the first embodiment, the user need to be introduced in advance call mode and select the interface before conversing, and call mode is chosen as " noise filtering pattern ", and selects the first filtered model or the second filtered model in the subpattern option.The first filtered model is " all sound outside the filtering owner ", and the second filtered model is " filtering except people's sound all sound ".When the user selected the first filtered model, man-machine interface can point out the user to enter the voice recording pattern, to obtain the voice messaging of pre-recording.The input method of this voice messaging of pre-recording will describe in detail below.
Certainly, the user also can select " common call mode ", or in the situation that the user does not select, system default is " common call mode ".
After the user sets call mode, can in communication process, implement the present embodiment with following step.
Step S101: enter call mode, obtain call voice information.Wherein, described voice messaging, i.e. user's sound, the expression of language such as " feeding ", " hello ".
Step S102: judge whether call mode is the noise filtering pattern.Be set to common call mode if judge call mode, rather than the noise filtering pattern, carry out so step S103: enter common call mode.That is, the voice messaging of input is not done any processing.Be set in advance the noise filtering pattern if judge call mode, continue to judge whether predefined subpattern is the first filtered model or the second filtered model so, thereby determine to carry out step S105 or step S108.
Step S105: when predefined subpattern is the first filtered model, judged whether the voice messaging of pre-recording, if do not pre-record voice messaging, then forwarded step S103 to: enter common call mode.If pre-record voice messaging, then carry out step S106: compare the frequency in the call voice information and the frequency range of voice messaging of pre-recording, and proceed step S107: filter the voice messaging that has the frequency outside the frequency range of the described voice messaging of pre-recording in the described call voice information.
Step S108: when predefined subpattern is the second filtered model, compare the frequency in the call voice information and the frequency range that prestores.Then, carry out step S109: filter the voice messaging that has the frequency outside the frequency range of pre-stored voice information in the described call voice information.The frequency range of described pre-stored voice information is set in advance before product export by manufacturer, is people's voice frequency range, and for example the described frequency range that prestores is 80Hz～12kHz.
By said method, namely can reach noise in the voice messaging of in communication process filtering input and the purpose of noise.If the user is owner itself, it can select the first filtered model, only keeps owner's sound itself, if the user is other people, then can select the second filtered model, the sound beyond the filtering people.No matter select any filtered model, all can realize noise filter function.Certainly, when the user wished that the other side can hear the sound of own environment of living in, perhaps own environment of living in was quiet and when need not filter out noise, the user can select " common call mode ".
Fig. 2 is the process flow diagram of the second embodiment of a kind of method of filtering call noise of the present invention.The second embodiment is similar to the first embodiment, and difference is, in a second embodiment, the user can be after entering talking state, select again whether to need to open the noise filtering pattern, and and then the chooser pattern, thereby offer the larger flexibility of operation of user.Before entering call mode, similarly, need to carry out the language recording, to obtain the language message of pre-recording.The method of this filtration call noise below will be described in detail in detail.
Step S101: enter call mode, obtain call voice information.
Step S102: judge whether to open the noise filtering pattern.In this step, can provide information in man-machine interface, the prompting user makes one's options to call mode.If the user selects not open the noise filtering pattern, then enter step S203: enter common call mode.If the user selects to open the noise filtering pattern, then enter step S204: judge whether subpattern is set as the first filtered model or the second filtered model.Here, same, can pass through man-machine interface, make one's options for the user.
Step S205: when being set as the first filtered model, compare the frequency in the call voice information and the frequency range of voice messaging of pre-recording, and then carry out step S206: filter the voice messaging that has the frequency outside the frequency range of the described voice messaging of pre-recording in the described call voice information.
Step S207: when being set as the second filtered model, comparing the frequency in the call voice information and the frequency range that prestores, and then carry out step S207: filter the voice messaging that has the frequency outside the described frequency range that prestores in the described call voice information.
By said method, can reach equally noise in the voice messaging of in communication process filtering input and the effect of noise.Judgement to call mode in the method for the filtration call noise among the present invention also can be finished before obtaining voice messaging, and both also can carry out simultaneously, and the present invention is not restricted this.
Fig. 3 is the process flow diagram of the preferred embodiment of the voice messaging input method of pre-recording in a kind of method of filtering call noise of the present invention.
Before the user converses, can carry out in advance by method shown in Figure 3 the recording of language message.Be understandable that, the user implements this method under quiet environment will obtain preferably effect.Step S301: open the noise filtering pattern; Step S302: open the first filtered model; Step S303: open sound-recording function; Step S304: receive user's voice messaging; Step S305: described user's voice messaging is stored as the voice messaging of pre-recording; Step S307: finish.After step S301, also can carry out step S306: open the second filtered model.Because therefore the front setting of dispatching from the factory of the frequency range of the language message that prestores of required use, after carrying out step S306, can directly go to step S307 in the second filtered model.
Certainly, in other embodiments, also can directly carry out step S303: open sound-recording function, and save step S301 and S302.The present invention is not restricted this.
Fig. 4 is the calcspar of the preferred embodiment of a kind of device that filters call noise of the present invention.As shown in Figure 4, the device of described filtration call noise comprises communication module 101, pattern setting module 102, voice module 103, comparison module 104, filtering module 105, recording module 106 and memory module 107.
Preferably, pre-stored voice information also is stored in the memory module 107, under the noise filtering pattern, comparison module 104 receives the call voice information that voice module 103 transmits, after itself and pre-record voice messaging or pre-stored voice information compared, filtered by 105 pairs of call voice information of filtering module, and be sent to communication module 101.Under common call mode, voice module 104 directly is sent to communication module 101 with call voice information.
In sum, even the method for filtration call noise of the present invention and device can also can keep speaking volume at ordinary times so that the user is in the noisy environment, converse swimmingly with other people, improve communication quality and efficient, also improved user experience.
The above only is preferred embodiment of the present invention, and the ordinary technical staff in the technical field of the invention is not within breaking away from spirit of the present invention and essence, when making various corresponding changes and distortion.Therefore, protection scope of the present invention is as the criterion when looking claims person of defining.
