Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the method flow graph of a kind of music tuner of the present invention;
Fig. 2 is the device construction block diagram of a kind of music tuner of the present invention;
Fig. 3 is the structure block diagram of the equipment of a kind of music tuner of the present invention.
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 obtains under the creative work prerequisite.
See also Fig. 1, preferred embodiment of the present invention, a kind of method of music tuner comprises:
S1. gather environmental sound signal, carry out the A/D conversion, obtain speech digit amount and storage;
Step S1 also comprises: described voice signal is carried out denoising, real-time recording, end-point detection, pre-emphasis.
The method of described end-point detection comprises: the energy measuring method, namely be in one section voice signal, judge method sound, the cone of silence, because quiet portion of energy is necessarily low than sound part, therefore a threshold value can be set, energy value is sound zone greater than the part of this threshold value, and energy value is the cone of silence less than the part of this threshold value.
Described pre-emphasis refers to the deamplification in the voice signal is compensated, because after sound sends from people's lip, the part that sound frequency is higher can decay, so need to compensate with the part of pre-emphasis to decay, pre-emphasis is exactly enable voice compensates high frequency by a Hi-pass filter loss.
S2. extract described speech digit amount and compare with default speech samples, obtain comparison result;
Described comparison is to carry out according to the similarity that the speech digit amount is mated in default speech samples, described comparison method comprises: the dynamic time axis calibration, compare according to the speech digit amount of inputting and the characteristic parameter of the speech samples of presetting, draw the phonic signal character parameter similarity identical with the speech digit amount of each sample.
S3. described comparison result is fed back to the user.
Comparison result comprises percentage value and/or oscillogram and/or the animation image of comparing rear acquisition with default speech samples.
Wherein, comparison result comprises the accurate percentage value of pronunciation, and described percentage value obtains by the ratio of described real-time recording and Received Pronunciation, simultaneously, can playback sound recording and standard sounding originally, so that the user again practises according to comparison result or begins new exercise.
Also the form of available sounds oscillogram shows comparison result, as: default speech samples is corresponding to a segment standard oscillogram, the sound generation real-time waveform figure that the user sounds or plays, this real-time waveform figure and reference waveform figure waveform are more approaching, show that the sound of sounding or playing is more close to default speech samples, therefore, the user can relatively can intuitively learn comparison result by two oscillograms.
Vivider ground with animation image appearance comparison result, shows the animation image such as the comparison result shows zone at playback equipment, as: when the user sounds or the sound played when consistent with the speech samples of presetting, the viewing area presents animation smiling face's icon.
Further, also comprise step S0 before the step S1, the form of default speech samples with database is stored in the playing device.
Those skilled in the art will appreciate that the method realization of the method available software of above a kind of music tuner, this software can be stored in the storer of the computing machines such as USB flash disk, CD, hard disk, ROM, RAM.
