Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
The embodiment of the invention mainly is to consider the both sides that often converse under noisy environment the other side's sound of can not hear clearly, therefore the user in advance on the portable terminal with oneself sound by under the sound recordings, and analyze the audible frequency that obtains user voice, information such as tone color.In the communication process afterwards voice signal is carried out extraction and analysis, the audio signal close with previously stored portable terminal user's sound coupling then carried out suitable gain and amplified, other voice signal can be thought noise substantially, such audio frequency component signal is carried out gain controlling, turn down its volume and suppress, at last adjusted audio-frequency signal coding is sent, the sound voice heard of the other side is just very clear like this, and noise greatly reduces, the bigger communication effect that improves.
At first see also Fig. 1,, comprise the steps: for gathering the schematic flow sheet of user vocal feature data in the embodiment of the invention
S101: user's voice is gathered by portable terminal;
S102: the voice that collect are carried out the phonetic feature analysis;
S103: the voice feature data that analyzes is preserved.
Before implementing adjusting mobile terminal sound output of the present invention, need set in advance voice feature data, it mainly comes user's voice is gathered by portable terminal, this environment generally is the collection under the smaller or noise-free environment in noise circumstance, here can repeatedly collect same user's voice, also can gather different user's voice, the voice feature data that collects is preserved.Make the user voice data of having preserved a standard in the portable terminal in advance by this acquisition mode, i.e. user vocal feature data, this user vocal feature data owner will comprise the audible frequency of user voice and tone color information or the like.
Accordingly, Fig. 2 shows the method flow diagram of the adjusting mobile terminal sound output in the embodiment of the invention, comprises the steps:
S201: portable terminal receives the voice signal of user in communication process;
This voice signal has comprised the user's voice signal at least, if in the noise circumstance of complexity, also can mix a large amount of noise signals, here can provide a software interface for the user, this voice output mode is set for the user, as in the place of voice environment more complicated, the user opens this voice output function on portable terminal, as in muting environment, the user can close this voice output function.Here can realize also whether decision opens this voice output function by the mode of software detecting, such as comparing with storaged voice characteristic in advance, when if voice signal is purer, do not need to open this function,, then open this function if voice signal is relatively more chaotic complicated.
S202: according to the user vocal feature data of storage in advance voice signal is carried out voice match and handle;
In advance Cun Chu voice feature data in advance the flow process in Fig. 1 realize that the user vocal feature data here comprise user's sounding audio-frequency and tone color information.
Need to prove, here at first to obtain audible frequency and tone color information in the voice signal, according to audible frequency and tone color information similarity in audible frequency in the user vocal feature data and the tone color information analysis voice signal, last grade classification according to the voice similarity that sets in advance mates voice signal for being used for speech data and noise speech data again.Whether the similarity here relatively can be judged voice signal in the user's communication process pure or noise is excessive or the like.
S203: the result to the speech data coupling carries out the voice control and treatment, and obtains dateout;
Need to prove, mainly be to the described user voice data processing and amplifying that gains here; And/or described noise speech data is carried out gain controlling handle.
S204: send the voice output data.
The embodiment of the invention is by voice comparative analysis and gain controlling combination, and the efficient voice input comes out suitably to amplify in will conversing, and correspondence suppresses noise signal, thereby has improved the communication effect under the noisy environment preferably.
Accordingly, the embodiment of the invention also provides a kind of portable terminal, specifically as shown in Figure 3 in, comprising:
Sending module 304 is used to send the voice output data.
This portable terminal is by carrying out matching treatment to the voice signal and the user characteristic data that receive, and the result of matching treatment is carried out the voice control and treatment, can improve the speech quality of voice output data, the increase user experience.
Accordingly, Fig. 4 also shows another structural representation of portable terminal in the embodiment of the invention, comprising:
Receiver module 401 is used for receiving the voice signal that blurs at communication process;
