Fig. 1 is a kind of flow chart of way of recording according to an exemplary embodiment, as shown in figure 1, the way of recording
For in terminal, comprising the following steps.
In step s 11, the recorded audio signals for recording to obtain under the first recording mode are obtained；
In step s 12, the signal characteristic of recorded audio signals is identified；
In step s 13, the second recording mode corresponding to signal characteristic is switched to continue to record.
In the present embodiment, by carrying out signature analysis to the recorded audio signals under current recording pattern, to determine current recording
Scene, so as to select recording mode corresponding with current recording scene automatically for user.So so that recording mode is recorded with actual
Sound field scape matching degree is higher, improves recording effect.Further, since user be less able to really to understand in actual use it is different
The essential difference of pattern background process, therefore it is difficult to make correct selection to be defined with scene in the environment being directly consistent, therefore,
Automatically suitable recording mode is selected for user, carries out the selection of recording mode manually without user, not only increase recording effect
Fruit, the complexity of user's operation is also reduced, improve Consumer's Experience.Meanwhile this process not only runs in recording at the beginning,
And the whole process of recording is through, and the switching of recording mode is carried out according to current recording signal in real time.
Optionally, step S11 includes：
Obtain the recorded audio signals that the first preset time period obtains of being recorded under the first recording mode.
Or
The recorded audio signals obtained with the second default section of first recording mode recording are gathered according to prefixed time interval.
For example, when user just starts recording, the first recording mode A of an acquiescence can be used, a period of time in recording,
As after 1 minute, the identification of signal characteristic is carried out to this obtained 1 minute recorded message, determines to record corresponding to the signal characteristic
Sound Mode B, recording mode B is switched to afterwards and continues to record.
In another example after using recording mode A recording a period of times, playback environ-ment or recording object may change, such as
The relative increase of noise reduces, or start record is voice, occurs music afterwards.So recorded audio signals also become accordingly
Change.Recorded audio signals are gathered by periodicity, such as carry out signature analysis every the recorded audio signals of collection 30 seconds in 3 minutes, in real time root
According to current recording signal behavior recording mode.
In alternative, by carrying out signature analysis to recorded audio signals, to determine current recording scene, so as to be automatically

In step S22, it is switched to the second recording mode corresponding to voice signal or music signal and continues to record.
According to the feature of the recorded audio signals object under current recording pattern, recorded audio signals can be divided into voice signal with
Music signal.Because voice signal and music signal have obvious difference in the characteristics such as frequency spectrum, bandwidth, while noise is eliminated and calculated
Method has an obvious difference for the negative effect size that unlike signal is brought, therefore voice signal and the record corresponding to music signal
Sound pattern is different.
The number of the hardware resource provided based on different hardware platforms and the support for whether having cloud service, for language
The identification of sound signal and music signal can have a variety of implementations.For example, the static statistics such as average, variance for signal
Feature is analyzed, or to the sensory features such as the tone of signal, brightness, and power spectrum, mel-frequency cepstrum coefficient (MFCC)
Etc. the index that can serve as making a distinction voice signal and music signal.It can also use and be based on when disposal ability is enough
Maximum-likelihood estimation or HMM (HMM) are used as decision rule grader, to enter to voice signal and music signal
Row is distinguished.In addition, known using neural network model by extensive voice and pattern obtained from music signal database training
Other algorithm, the identification to signal characteristic are more accurate.
Under the support in network and high in the clouds, actual scene can often be carried out more specifically dividing and carrying out more smart
True differentiation processing, for example, according to the alternative sounds feature of voice, e.g., the difference of speaker's sex, and physiology, tone color, sound
The difference of domain, style etc., different voice recording patterns is respectively adopted.
It is different according to the history sound recordings of user at the same time it can also be supplied to the more personalized services of user
User recommends different recording modes, and such as the user, using interviewing, recording mode is more, and user's occupation may be reporter, then often
It can give tacit consent to during secondary recording and be recorded using interview recording mode.
In alternative, by the way that the type of recorded audio signals is identified, voice signal and music signal are adopted respectively
Recorded with different recording modes, further increase recording mode and actual recording scene matching degree, recording effect is more

It is a very quiet environment that this is can consider during intensity.When playback environ-ment sound is more than default noise intensity, in order to improve
Recording effect so that the voice signal of recording is become apparent from, it is necessary to be carried out using noise reduction process algorithm to the voice signal of recording
Processing.It is for instance possible to use spectrum-subtraction or least mean-square error (LMS) filtering suppress for noise.
In alternative, by being detected to the ambient noise of playback environ-ment, determine corresponding to current recording scene
Recording mode, i.e., different recording modes, corresponding noise reduction process mode is also different.So, by entering to recording scene
The finer division of row so that recording mode is more preferable to the matching degree for scene of recording, and the voice signal for recording to obtain is more clear
It is clear, further increase recording effect.
