Second analytic unit is used to analyze the mode of described accompanying song, determines the melody descant of described accompanying song;
The mode regulon is used to calculate the difference between the frequency of described highest frequency and described melody descant, regulates the mode of described accompanying song according to described difference;
Output unit, the mode that obtains after being used for regulating according to described mode regulon is play described accompanying song.
Preferably, in the said apparatus, described voice signal is the voice signal of the highest frequency that can sing of described singer.
Preferably, in the said apparatus, described mode regulon comprises:
Computation subunit is used to calculate the difference between the frequency of described highest frequency and described melody descant;
Mutual subelement is used for after described computing unit calculates described difference, and output one is used to inquire whether described accompanying song is carried out the message that mode is regulated, and receives the affirmation indication of described singer's input;
Regulate subelement, be used for after described interactive unit receives described affirmation indication, regulating the mode of described accompanying song according to described difference.
Preferably, in the said apparatus, described adjusting processing unit is further used for the mode of described accompanying song is carried out falling tone or rising tune processing, to reduce described difference.
Preferably, in the said apparatus, also comprise:
Preserve the unit, be used to preserve described highest frequency.
From the above as can be seen, the method and the device of the mode of the adjusting accompanying song that the embodiment of the invention provides, can come accompanying song is automatically adjusted according to singer's individual range characteristics, make accompanying song and singer's individual range characteristics more mate, thereby the singer can give song recitals preferably.And the embodiment of the invention can also determine whether that accompanying song is carried out mode to be regulated, and makes singer's performance have more initiative according to singer's selection.
Description of drawings
Fig. 1 is the process flow diagram of method of the mode of the described adjusting accompanying song of the embodiment of the invention;
Fig. 2 is the structural representation of device of the mode of the described adjusting accompanying song of the embodiment of the invention;
Fig. 3 is the structural representation of the described mode regulon of the embodiment of the invention.
Embodiment
The embodiment of the invention is arranged to accompanying song automatically be fit to the mode that this singer sings, thereby is made the singer can sing corresponding song preferably according to the range scope of singer's voice.The present invention will be further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the method for the mode of the described adjusting accompanying song of the embodiment of the invention may further comprise the steps:
Here, described voice signal is the voice signal of the highest frequency that can sing of described singer.The singer can sing out two continuous pitches, sing arbitrarily mode all can, to obtain the descant that singer oneself can sing out.Singer's voice signal can be gathered by the input media of microphone, microphone and so on.
Here, by described voice signal being analyzed the highest frequency that finds the singer to sing.
Here, utilize the mode analytical algorithm, analyze the mode obtain accompanying song, determine the melody descant of this accompanying song,, the highlyest be meant that frequency is the highest here.
Here, mode by the described accompanying song of automatic adjusting, make that described difference is reduced, make described accompanying song more mate singer's range scope, for example, the highest frequency that can sing the singer can carry out falling tone to described accompanying song and handle during less than the frequency of described melody descant; When the highest frequency that can sing the singer is higher than the frequency of described melody descant, can carries out rising tune to described accompanying song and handle.
Certainly, sometimes the singer may wish mode not to be carried out any adjusting.In order to make the singer can obtain more initiative, can select voluntarily whether mode to be automatically adjusted, the described method of present embodiment calculates in step 14 after the described difference, can also further export one is used to inquire whether the singer needs described accompanying song is carried out the apply for information that mode is regulated: after the affirmation indication that receives described singer's input, regulate the mode of described accompanying song again according to described difference; After the rejection indication that receives described singer's input, described accompanying song is not carried out mode and regulate, and directly play described accompanying song with former mode.
In the said method, can also preserve in the step 12 highest frequency that the specific singer that obtains can sing.Before this singer sings next time, just can not need above-mentioned steps 11～12, directly utilize the above-mentioned highest frequency of preserving in advance, and enter mode analysis and the adjusting that step 13 and 14 is carried out corresponding accompanying song, thereby make singer's performance reach more desirable automatic adaption function.
From the above as can be seen, said method comes accompanying song is automatically adjusted according to singer's individual range characteristics, make accompanying song and singer's individual range characteristics more mate, thereby the singer can give song recitals preferably.
Based on the method for the mode of above-mentioned adjusting accompanying song, the embodiment of the invention also provides a kind of device of regulating the mode of accompanying song, and this device can be arranged in the portable handheld devices such as mobile phone.As shown in Figure 2, this device specifically comprises:
Collecting unit 21 is used to gather the voice signal that the singer sings;
First analytic unit 22 is used to analyze described voice signal, determines the highest frequency of described voice signal;
Second analytic unit 23 is used to analyze the mode of described accompanying song, determine described accompanying song the melody descant;
In the said apparatus, the voice signal that described collecting unit 21 is gathered is the voice signal of the highest frequency that can sing of described singer.Can also comprise in the said apparatus that one preserves the unit, be used to preserve described highest frequency.
Preferably, as shown in Figure 3, above-mentioned mode regulon 24 specifically can comprise:
Computation subunit 241 is used to calculate the difference between the frequency of described highest frequency and described melody descant;
Mutual subelement 242 is used for after described computing unit calculates described difference, and output one is used to inquire whether described accompanying song is carried out the message that mode is regulated, and receives the affirmation indication of described singer's input;
Regulate subelement 243, be used for after described interactive unit receives described affirmation indication, regulating the mode of described accompanying song according to described difference.Here, this regulates processing unit, can also be further used for the mode of described accompanying song is carried out falling tone or rising tune processing, to reduce described difference.
In sum, the method and the device of the mode of the adjusting accompanying song that the embodiment of the invention provides, individual range characteristics according to the singer come accompanying song is automatically adjusted, make accompanying song and singer's individual range characteristics more mate, thereby the singer can give song recitals preferably.
