Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Data traffic when saving voice communication, as shown in Figure 1, the embodiment of the invention provides a kind of implementation method of voice communication, comprising:
101, obtain the speech data of transmitting terminal;
Described transmitting terminal can be a user terminal, for example: mobile phone.
In addition, when carrying out between the user in the process of voice communication, user's sound is converted into audio data stream in described transmitting terminal, and this audio data stream is a string speech data.
102, judge whether described speech data is valid data;
Carry out between the user in the process of voice communication, if both sides' normal dialog, then the speech data of sound through being converted to that sends by both party this moment is valid data; The speech data of other sound (as ambient noise etc.) through being converted to is invalid data, and in addition, if under the situation that the user does not sound, then the speech data that is obtained also is invalid data.
At the speech data that gets access to is under the situation of valid data, carry out step 103.
103, send described speech data to receiving terminal.
Described speech data is valid data.
The executive agent of above steps can be an independent community, also can be a functional part in the transmitting terminal.
The implementation method of the voice communication that the embodiment of the invention provides, whether the speech data by judging transmitting terminal is valid data, and according to judged result shielding invalid data, only send valid data to receiving terminal, the data traffic in the time that thereby voice communication can being saved, and then reduce a part of network traffics expense.
Embodiment one:
The three elements of sound are tone, loudness and tone color, and its medium pitch is by the frequency decision of sound wave, and loudness is by the amplitude decision of sound wave, and tone color is the characteristic of sounding body.The embodiment of the invention provides a kind of specific implementation method of voice communication in conjunction with the decisive factor of frequency and these two sound of amplitude, as shown in Figure 2, specifically may further comprise the steps:
201, the recording literal that prestores in the transmitting terminal one section and be used to record;
Described transmitting terminal can be a portable terminal.Higher word and the lower word of audible frequency of audible frequency contained in described recording literal.The user reads aloud described recording literal according to the sound that carries out voice communication at ordinary times, imports in the portable terminal and record by microphone to obtain data flow, the data flow of promptly recording.
202, obtain the recording data flow of transmitting terminal;
Be specifically as follows, a functional part of transmitting terminal obtains the recording data flow that is obtained by this transmitting terminal recording, and described recording data flow is a string recording data.
203, analyze described recording data flow, obtain the frequency range and the amplitude range of described recording data flow;
Because the frequency of sound wave and two decisive factors that amplitude is sound, so all comprise frequency and amplitude information in each recording data.Analyze in this recording data flow each recording data frequency and amplitude, note the maximum of recording data frequency and the maximum and the minimum value of minimum value and amplitude respectively, the frequency range and the amplitude range of the data flow that finally obtains recording.
