Embodiment
Here will be described exemplary embodiment in detail, its sample table is shown in
in accompanying drawing.Description below relates to
accompanying drawingtime, unless otherwise indicated, different
in accompanying drawingsame numbers represent same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
The technical scheme that disclosure embodiment provides, relates to the terminal can carrying out recording.Terminal, by automatically identifying the scene of current recording, helps end-user's mind to select the recording mode corresponding to scene of current recording, and processes accordingly the sound signal obtained of recording on backstage.Like this, save user's trouble of manual selection modes before recording starts, this process not only runs on recording at the beginning simultaneously, but runs through the whole process of recording and real-time switching according to current environment.Secondly, real-time background process descriptive information can be provided at the User Interface of Recording Process, and provide real-time with design interface that is user interactions, this is to can better allow user understand the pattern of background process, simultaneously for part professional user provides personalized setting, also in order to increase the robustness of backstage scene Recognition, erroneous judgement is reduced.
fig. 1it is the flow process of a kind of way of recording according to an exemplary embodiment
figure,
as Fig. 1shown in, the way of recording is used for, in terminal, comprising the following steps.
In step s 11, to record under obtaining the first recording mode the recorded audio signals obtained;
In step s 12, the signal characteristic of recorded audio signals is identified;
In step s 13, be switched to the second recording mode corresponding to signal characteristic and proceed recording.
In the present embodiment, by carrying out signature analysis to the recorded audio signals under current recording pattern, to determine current recording scene, thus automatically for user selects the recording mode corresponding with current recording scene.Like this, make recording mode and the actual scene matching Du Genggao that records, improve recording effect.In addition, because user seldom really can understand the essential difference of different pattern background process in actual use, therefore define in the environment directly conformed to scene and be difficult to make correct selection, therefore, automatically for user selects suitable recording mode, manually carry out the selection of recording mode without the need to user, not only increase recording effect, also reduce the complexity of user operation, improve Consumer's Experience.Meanwhile, this process not only runs on recording at the beginning, but runs through the whole process of recording, and carries out the switching of recording mode according to current recording signal in real time.
Optionally, step S11 comprises:
The recorded audio signals that first preset time period of recording under obtaining the first recording mode obtains.
Or
According to the recorded audio signals that prefixed time interval collection obtains with the default section of described first recording mode recording second.
Such as, when user has just started to record, the first recording mode A that one can be adopted to give tacit consent to, a period of time in recording, after 1 minute, this 1 minute the recorded message obtained is carried out to the identification of signal characteristic, determine the recording mode B that this signal characteristic is corresponding, be switched to recording mode B afterwards and proceed recording.
Again such as, adopt recording mode A to record after a period of time, playback environ-ment or recording object may change, and relatively increase or reduces as noise, or what start record is voice, occurs music afterwards.Such recorded audio signals also changes accordingly.By periodically gathering recorded audio signals, the recorded audio signals as gathered 30 seconds every 3 minutes carries out signature analysis, in real time according to current recording signal behavior recording mode.
In possibility, by carrying out signature analysis to recorded audio signals, to determine current recording scene, thus automatically for user selects the recording mode corresponding with current recording scene.Like this, make recording mode and the actual scene matching Du Genggao that records, improve recording effect.In addition, carry out the switching of recording mode in real time according to current recording signal, further increase recording effect.Further, recording is omnidistance can without the need to the manual operation of user, and simplify the degree of load of Recording Process, user experience is better.
fig. 2it is the flow process of a kind of way of recording according to another exemplary embodiment
figure,
as Fig. 2shown in, optionally, step S13 comprises:
In the step s 21, according to signal characteristic, recorded audio signals is divided into voice signal or music signal;
In step S22, be switched to voice signal or the second recording mode corresponding to music signal proceeds recording.
According to the feature of the recorded audio signals object under current recording pattern, recorded audio signals can be divided into voice signal and music signal.Because voice signal and music signal have obvious difference in the characteristic such as frequency spectrum, bandwidth, the negative effect size that noise cancelling alorithm brings for unlike signal simultaneously has obvious difference, and therefore voice signal is different with the recording mode corresponding to music signal.
The number of the hardware resource provided based on different hardware platforms and whether have the support of cloud service, the identification for voice signal and music signal can have multiple implementation.Such as, the static statistics feature such as average, variance for signal is analyzed, or the sensory features such as tone, brightness to signal, and power spectrum, mel-frequency cepstrum coefficient (MFCC) etc. can as the index distinguished voice signal and music signal.Can also to adopt when processing power is enough based on Maximum-likelihood estimation or Hidden Markov Model (HMM) (HMM) as decision rule sorter, voice signal and music signal are distinguished.In addition, utilize the algorithm for pattern recognition that neural network model obtains through extensive voice and music signal database training, more accurate to the identification of signal characteristic.
Under the support in network and high in the clouds, often actual scene can be divided more specifically and carry out more accurate differentiation process, such as, according to the alternative sounds feature of voice, as, the difference of speaker's sex, and the difference of physiology, tone color, range, style etc., adopt different voice recording patterns respectively.
Simultaneously, the service of the more property of user can also be supplied to, according to the history sound recordings of user, for different users recommends different recording modes, as this user adopts interview recording mode more, this user's occupation may be reporter, then can give tacit consent to when recording at every turn and adopt interview recording mode to record.
In possibility, by identifying the type of recorded audio signals, adopt different recording modes to record respectively to voice signal and music signal, further increase recording mode and actual scene matching degree of recording, recording effect is better.
fig. 3it is the flow process of a kind of way of recording according to another exemplary embodiment
figure,
as Fig. 3shown in, optionally, step S22 comprises:
In step S31, obtain the noise intensity of ambient noise present;

In possibility, short-time energy can be utilized to weigh the size of neighbourhood noise, can think that when neighbourhood noise is less than default noise intensity this is a very quiet environment.When playback environ-ment sound is more than default noise intensity, in order to improve recording effect, making the voice signal of recording more clear, needing to adopt noise reduction process algorithm to process the voice signal recorded.Such as, spectrum-subtraction or least mean-square error (LMS) filtering can be adopted to suppress for noise.
In possibility, by detecting the ground unrest of playback environ-ment, determine the recording mode corresponding to current recording scene, namely different recording modes, corresponding noise reduction process mode is also different.Like this, by carrying out meticulousr division to recording scene, make the matching degree of recording mode to recording scene better, the voice signal that recording obtains is more clear, further increases recording effect.

In step S43, when receiving the selected operation to session recording pattern or recording mode option corresponding to interview recording mode, being switched to recording mode corresponding to selected recording mode option and proceeding to record.
When playback environ-ment sound is below default noise intensity, an enough quietly environment can be thought, do not need to carry out relevant treatment for neighbourhood noise.For recorded speech, neighbourhood noise is less also several situation, as recording of attending class, session recording, interview recording, or simple at a quiet environment to the voice recording of someone, etc.Because under this several scene, neighbourhood noise is very little, signal to noise ratio (S/N ratio) is general higher, simultaneously record object can be very clear and definite for indivedual spokesman, source of sound generally can not be crossed and frequently, significantly shift one's position simultaneously, so adopt the mode of Beam synthesis, the sound picking up speaker with the recording of directive property will bring better effect, reduces the interference for recorded audio signals that excessive noise reduction brings on the one hand, removes the little sound talk of other participants or other room noises on the one hand as far as possible.
When general voice is recorded, only can retain amplitude control treatment to realize reducing for the amplitude peak of playback environ-ment, relevant treatment not carried out to neighbourhood noise.
For in the playback environ-ment such as general small-sized party, because words person's quantity is usually not unique, cutting sound source position may significantly change fast, and the mode of the directive property of inapplicable Beam synthesis recording.Therefore manually being determined by user when switching conference model can be more accurate.And Acquisition Model is due to its singularity, manually being determined by user also can be more accurate.
In possibility, when neighbourhood noise is lower, general voice recording pattern can be adopted when initial recording, noise reduction process not carried out to the voice signal recorded, simultaneously, the option of display conference recording mode or interview recording mode in terminal, user can, according to actual environment situation, select corresponding recording mode to proceed recording, like this, the selection of recording mode more accurately, more realistic scene, recording effect is also better.
Optionally, when recorded audio signals is music signal, step S22 comprises:
Adopt music recording pattern to proceed recording, music recording pattern does not do noise reduction process to the recorded audio signals that continuation recording obtains.
In possibility, in order to ensure that music class signal can be recorded and few distortion of trying one's best preferably, not using the algorithm of any noise reduction, only retaining amplitude control treatment.Like this, more true to nature to the recording of music, better effects if.
