Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is purged, is complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, those skilled in the art's every other embodiment obtained without creative efforts,
It shall fall within the protection scope of the present invention.
Embodiment one
Adjustment singing songs difficulty method provided in an embodiment of the present invention sings system, the intelligence such as mobile phone, PAD suitable for the K of KTV
The K song software installed in energy terminal and other voice systems and software.For ease of description, system is sung with the K of KTV below
For be illustrated, it should be appreciated that following proposal be equally applicable to the K installed on the intelligent terminals such as mobile phone, PAD song it is soft
Part.
Referring to attached drawing 1, a kind of flow chart adjusting singing songs difficulty method provided in an embodiment of the present invention is specifically included
Following steps:
S101, accompaniment signal to be given song recitals is received；
S102, user voluntarily select to be that the tonality of accompanying song is carried out rising tune or falling tone；
In existing musical instrument system, according to the difference of vibration frequency, tone can be divided into different sound level, in the world generally
Use division mode for 12 equal temperances.12 equal temperances, which refer to, is divided into 12 impartial frequency contents for a pure octave, i.e., and 12
A semitone: A, A#, B, C, C#, D, D#, E, F, F#, G, G#, the vibration frequency difference 2 of each adjacent semitone1/12, in a pure octave
Vibration frequency maximum between each semitone differs 2 times.If the vibration frequency of each frequency content is increased 21/12, then it is equivalent to sound
Tune increases a semitone, whereas if the vibration frequency of each frequency content is reduced by 21/12, then being equivalent to reduces tone
One semitone.
Assuming that the frequency of former audio signal is f, the frequency after modulation is f ', then should meet between them: f '=f*2d /12, modulation factor alpha=2d/12, wherein d=± 1, ± 2, ± 3,.As d > 0, rising tune, falling tone on the contrary are realized.
The user voluntarily selects to be that the tonality of accompanying song is carried out rising tune or falling tone, and specifically include: user is voluntarily
Selection needs the semitone number gone up and down, to adapt to the range of user.That is the tone of the most comfortable that can be sung according to oneself of user, choosing
It selects and accompanying song is subjected to modulation processing, for example, the tone of the most comfortable that user can sing is C tune, the tone of accompanying song
For E tune, at this point, accompanying song is carried out falling tone processing by user's selection, and three chromatic scales are reduced.Otherwise principle is identical.
S103, modulation processing is carried out by the demand of user to the accompaniment of song, the accompanying song after obtaining modulation；
About the algorithm of audio modulation, the algorithm of comparative maturity has Time-Domain algorithm, frequency domain interpolation and phase acoustic code at present
Device method.Preferably, it in the present embodiment, is handled with the rising-falling tone that phase vocoder method is accompanied.The processing step of the algorithm are as follows:
One, duration is regular, for the primary sound sound signal to be carried out duration adjustment by phase adjustment；The wherein phase
Adjustment can specifically be divided into three phases:
(1) decomposition of signal: short term Fourier transform is carried out to the voice signal of input frame, time-domain signal is converted
The amplitude and phase information of frame signal are inputted with acquisition to separating the amplitude of signal and phase for frequency-region signal.
(2) synthesis phase is calculated: according to modulation factor alpha, adjustment phase place information, specific algorithm are as follows:
Delta_phi=omega+princarg (phi-phi0-omega)；
Phi0=phi；
Psi=princarg (psi+delta_phi* α)；
Delta_phi- phase increment；Phi- present frame phase；Phi0- previous frame phase；Omega- initial phase；Psi- is closed
At phase；Princarg operation is for adjusting phase increment to (- π-π).
(3) signal recombines: remaining unchanged, is only adjusted to phase, synthetic frame in the amplitude of synthesis phase, every frame
Frequency spectrum by Fourier inversion to time-domain signal.
Two, sampling rate conversion, after having carried out phase adjustment, obtained voice signal becomes primary sound sound signal duration
α times, i.e. the signal duration of rising tune is elongated, and the signal duration of falling tone shortens.It needs to carry out scaling to voice signal, is restored to original
The duration come is to realize modulation not speed change.Method particularly includes: modulation factor alpha=f '/f first asks f ', the greatest common divisor of f, abbreviation
Score f '/f is fraction in lowest term M/N, and the voice signal after modulation is carried out M times of interpolation, after after low-pass filter filters,
Carry out N times of extraction.So far, voice is identical as raw tone length after modulation.
Accompanying song after S104, output modulation；
It preferably, is that the accompanying song after modulation is exported by loudspeaker or earphone in the embodiment of the present invention.
S105, acquisition receive the human voice signal issued when user gives song recitals；
Herein, it is important to note that, the accompaniment after modulation is received by human ear, and user is drilled based on the accompaniment after modulation
It sings.
The acquisition, which receives the human voice signal issued when user gives song recitals, to be obtained by acquiring receiving device, excellent
Selection of land receives the voice signal issued when user gives song recitals by microphone in the present embodiment.
S106, the modulation processing opposite with accompanying song is carried out to the received human voice signal of acquisition；
The modulation processing opposite with accompanying song is carried out to the received human voice signal of acquisition, is specifically included: being worked as song
Accompaniment is when carrying out rising tune processing, and human voice signal carries out falling tone processing；When accompanying song is to carry out falling tone processing, human voice signal
Carry out rising tune processing.
The modulation processing opposite with accompanying song is carried out to the received human voice signal of acquisition, is specifically included: the people
Acoustical signal is consistent with the accompanying song progress semitone number of modulation processing, so that the sound of human voice signal and former singer after modulation
It adjusts consistent.For example, when accompanying song is rise the rising tune processing of 5 semitones, then, human voice signal is to carry out drop 5 half
The falling tone of sound is handled.
Preferably, in the present embodiment, it is mediated with the lifting that SOLA-FS algorithm improved in time domain carries out human voice signal
Reason.The processing step of the algorithm are as follows:
One, duration is regular, for the primary sound sound signal to be carried out duration adjustment by the similar addition method of waveform；Wherein institute
The similar addition method of waveform is stated to be specifically as follows:
It is illustrated by taking rising tune as an example, framing is carried out to voice signal, each frame voice is regarded as a phoneme, according to language
Sound signal periodic regime determines that voice framing length L, rising tune coefficient replicate one section of n at every frame voice end in voiceless sound section for α
=L* (α -1) come achieve the purpose that elongate phoneme duration.In voiced segments, when to guarantee that copying voice is connected with former speech frame
The continuity of phase, the length of copying voice are the integral multiple in voiced segments voice fundamental period.
Determine the optimization length of duplication section voice method particularly includes: using correlation function algorithm find every frame voice last
The maximum correlation of section k point voice and its adjacent the last period k point voice, thereby determines that out the optimization length of duplication section voice
(when k takes different value, only when k is equal to pitch period, this two sections correlation just reaches maximum).The value range of k with
Centered on length n, it is moved forward and backward h point, then the maximum allowable displacement for finding correlation is (n-h)-(n+h).When every frame voice
The maximum value of the cross-correlation coefficient of final stage k point voice and its adjacent the last period k point voice (works as k=kmaxWhen) it is greater than one
When given threshold value, illustrates that the latter half of the voice of present frame is voiced sound, at this moment can pass through duplication current frame speech
The multiple of voiced sound pitch period elongates the frame voice, and pitch period is k at this timemax, until the frame voice length is greater than L '=L*
α stops splicing；When the maximum of every frame voice final stage k point voice and the cross-correlation coefficient of its adjacent the last period k point voice
When being worth less than a given threshold value, illustrates that the latter half of current frame speech does not have quasi periodic, be determined as voiceless sound section, at this moment
Replicate the last n point of current frame speech directly to realize elongation speech frame.
Voice falling tone process and rising tune process on the contrary, the waveform convertion process of voice falling tone and voice rising tune be it is the same,
Shorten the duration of each phoneme under crude sampling rate.After voice signal sub-frame processing, each frame is a phoneme, with
Voice rising tune it is different be exactly, falling tone be delete speech frame in one section achieve the purpose that shorten phoneme duration.It is identical
, in voiceless sound section, one section of n=L* (1- α) at every frame voice end is deleted, α is falling tone coefficient, when shortening phoneme duration to reach
Between purpose, in voiced segments, the length for deleting section voice should also be the integral multiple in voiced segments voice fundamental period, just can guarantee
Phase continuity when linking.
After replicating or deleting the multiple of pitch period, quarter window has been added to be filtered at the connecting points of every section of voice,
Part high-frequency noise is inhibited, is played a good role to phase continuity at connecting points is improved.Certainly, there are also other
Window, such as Hanning window, hamming window, rectangular window etc..
Two, sampling rate conversion, after having carried out sola algorithm, obtained voice signal becomes primary sound sound signal duration
α times, i.e. the signal duration of rising tune is elongated, and the signal duration of falling tone shortens.It needs to carry out scaling to voice signal, is restored to original
The duration come is to realize modulation not speed change.Method particularly includes: modulation factor alpha=L '/L first asks L ', the greatest common divisor of L, abbreviation
Score L '/L is fraction in lowest term M/N, and the voice signal after modulation is carried out M times of interpolation, after after low-pass filter filters,
Carry out N times of extraction.So far, voice is identical as raw tone length after modulation.
Wherein, in the present invention, the modulation processing method of human voice signal, which can be used, handles identical algorithm with accompaniment modulation,
Different algorithms can also be selected.
Further, the processing of other audio frequency effects can also be carried out to human voice signal in the present embodiment, such as reverberation is prolonged
When and other effects etc..
