[Embodiment] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings and the embodiments, so that the realization process of the present invention for solving the technical problems and achieving technical effects can be fully understood and implemented. First, the single-voiced singing system of the present invention will be described. Please also refer to "Figure 1" and the "Figure 1" is a block diagram of the single-voiced singing system of the present invention. The single person and sound song disclosed in the present invention includes: a parameter input module 10, a sound input module 20, a sound analysis module 3〇, a harmony module 4〇, a mixing module 50, and an output module. 60. The parameter input module 10 is configured to receive setting parameters. The foregoing setting parameters include a method of setting a compressed sound waveform, a stretched sound waveform, an increased overtone waveform, and a sound waveform distortion to change the sound waveform to correspond to different male and female harmony, female harmony, special harmony, single harmony, double Set items such as harmony and multi-person harmony. Specifically: when the male voice is singing and the female voice is selected, the output module 60 outputs the male singing voice and the female voice harmony; when the male voice 200923676 is singing and selecting the multi-person harmony, the output module 60 outputs The voice of male voices and the harmony of many people. Please refer to "Figure 2" and "Figure 2" for the audio signal waveform. The voice input module 20 is configured to receive the vocalist's voice signal 8 〇. The voice nickname 80 攸 indicates that the three main features are Pitch, Timbre, and Volume 83. As shown in Figure 2, the so-called pitch 81 refers to the level of the sound, which is determined by the frequency generated by the vibration of the sounding object. This frequency is the fundamental frequency of the sound signal. The higher the frequency, the higher the sound. The sharper it is. The tone 82 is determined by the different overtone variations scattered in the fundamental frequency spectrum. The sound signal is actually accompanied by many different frequencies of overtones in addition to the fundamental frequency, because these different overtones determine different timbres 82.曰83 refers to the amplitude of the sound signal, which represents the strength of the sound energy, which is the sound of the sound. Through the above description, the voice input module 2 transmits and receives the voice signal 80 of the singer to the sound analysis module 30, and the sound analysis module 3 analyzes the first spectrum information according to the sound signal, wherein the first spectrum information includes Pitch 81, tone 82, volume 83, or a combination thereof. The setting parameters and the first spectrum information are transmitted to the harmony module 40 according to the setting parameters received by the parameter input module 10 and the first spectrum information analyzed by the sound input module 20. The harmony module 40 adjusts the first spectrum information to at least one second spectrum information that matches the set parameter, and combines the second spectrum information into at least one of the first and 200923676 voice signals, wherein the second spectrum information includes the sound High, tone or volume and their combinations. The harmony module 40 adjusts the pitch of the first spectrum information 81, the tone 82, the volume 83 or the like by setting parameters to compress the sound waveform, stretch the sound waveform, increase the overtone waveform, and change the sound waveform of the sound waveform distortion. Combined into second spectrum information. For the second spectrum information after the adjustment, in order to avoid the waveform distortion effect in the second spectrum information, the effect of the waveform distortion in the second spectrum information is too obvious, so that the waveform with too much distortion can be calculated and compensated by the existing calculation means, which is a conventional technical means, and is not performed here. Narration. In short, the harmony module 40 is a function of changing the sound, and the male voice can be changed into a female voice according to the setting parameters received by the parameter input module 10, and the female voice can be changed into a male voice, and even the Donald Duck and the machine war can be changed. ...the sound of the special bead effect, in fact, the sound signal is used to change the pitch of the pitch 81 to create a variety of pitch 81, and also use a variety of overtones to change the tone color, and then achieve a special effect of the sound. The mixing module 50 is configured to mix the sound signal and the first sum sound signal into a second sum sound signal. Then, when the output module 60 plays the second sum audio signal, the sound signal and the first sum signal are simultaneously played, and the singer can hear the two sound signals appear at the same time. In addition, the system may further include a storage module 71 and a marking module 72.

The singer can choose the "option %" of "Male Voice Harmony", "Female Voice Harmony" or "Special Consonant", "Different - Option 91 Rhyme * _Set the parameters, you can also select the second = item 91 of ".. Harmony", "Double Harmony" or "Multiplayer" - the different second option 91 also corresponds to different settings. Parameter, parameter wheel = module ίο 'The setting parameters will be received (step 100). j In the embodiment, the singer selects the "Female Harmony" of the first option 91 and the "Double Harmony" of the first option 91. Therefore, the setting parameters corresponding to "Female Harmony" and "Single Harmony" It is the "Female Voice Harmony Parameter" and the "Single Harmony Parameter", and the "Female Voice Harmony Parameter" is the compressed sound waveform that causes the pitch value to increase, so that the pitch value is higher than the sound signal and becomes a different sound signal. The single-person harmony parameter is to increase the harmonic waveform to increase the tone waveform, so that the vertical waveform is different from the sound signal and converted into different sound signals. When you press "OK" (as shown in "Figure 4"), the parameter setting module 1〇 will receive the setting parameters as "Female Harmony Parameters" and "Single Harmony Parameters". 200923676, in the second picture 4, also shows the implementation of the 砰, that is, in order to make the f type ^ single way, in the first - pull-down menu 93, you can choose "male harmony", "female harmony" Or one of the "Special Consonants" drop-down menus, you can choose one of the "Single Harmony" people: People. In the embodiment, the singer selects "Female Harmony" in the first pull-down menu 93 and "Double Harmony" in the second drop-down menu %, because, and "female harmony" The setting parameters corresponding to "Single Harmony" are "Female Harmony Parameters" and "Single Harmony Parameters", and "Female Harmony Parameters" are the condensed sound waveforms that increase the pitch value and make the pitch The value is higher than the sound signal / converted to a different sound day A. The "single harmony parameter" is to increase the harmonic waveform so that the two-color waveform is increased, so that the sound waveform is different from the sound signal, and the sound is changed to different sounds = 峨. When you press "OK" (as shown in "Figure 4"), the parameter setting group 10 will receive the setting parameters as "Female Harmony Parameters" and "Single Harmony Parameters". In "Picture 4", only a set of menus and a set of drop-down menus are used as instructions. Of course, you can use multiple sets of menus and multiple sets of drop-down menus to perform the same. You can also achieve male and female harmony and female harmony. And a variety of harmony modes of special chorus. After the parameter setting module 1 is configured, the voice input module 2 receives the singer's voice signal 110 (step 200), as shown in the "5th drawing" and the voice input module 2 transmits and receives. The voice signal of the singer is n〇 to the sound analysis module 3〇, and the sound analysis module 3〇 analyzes the first-spectrum information according to the sound signal 11() 11 200923676, where the 'the first spectrum information includes the first pitch value 1U. The first timbre value 112 and the first volume value 113 (step 3 〇〇). Then, please refer to the "5B" diagram, and the setting parameters received according to the parameter input module 1 are "female harmony parameters" and "single harmony parameters", and are analyzed by the sound input module 20. The first spectrum information transmits the setting parameters and the first spectrum information to the harmony module 4〇. The harmony module 40 adjusts the first spectrum information to the second spectrum information in accordance with the setting parameter "female harmony parameter" and combines the second spectrum information into the first sum audio signal 120 (step 400). The second spectrum information includes a second pitch 121, a second timbre 122, a third volume 123, or a combination thereof. The harmony module 4 adjusts the first pitch value ill and the first tone of the first spectrum information by setting parameters to compress the sound waveform, stretch the sound waveform, and increase the overtone waveform and the sound waveform distortion to change the sound waveform. The value 112, the first volume value 113 or its blend is the second spectrum information. The sound mixing module 50 is configured to mix the sound signal 110 and the first sum sound signal 12 into the second sum sound signal 130 (step 500), as shown in the "5C figure", the solid line indicates the sound signal 11 〇, the dotted line The first sum signal 120 is indicated, and the two are mixed to represent the first and the audible signals 130. When the output module 60' outputs the second and audio signals 130, the audio signal 110 and the first harmony signal 120' are simultaneously played and the singer can hear both audio signals appear simultaneously (step 6). The first spectrum information is described in the embodiment as a combination of the first pitch value 1U, the first color value 112, and the first volume value 113. Therefore, when the adjustment is performed, the first pitch value m is simultaneously The tone value 112 and the first volume value 113 are adjusted 12 200923676 to be the second spectrum of the second pitch 12, the second tone 122, and the third volume 123; however, in practice, the first spectrum information does not necessarily need to be The first pitch value ill, the first timbre value 112, and the first volume value 113 are simultaneously adjusted, and the second pitch value m, the first timbre value 112, or the first volume value may be adjusted independently, or the first volume value may be adjusted. Any combination of the pitch value 11 and the first timbre value 112 and the first volume value. For example, the means for compressing the sound waveform is only a means for adjusting the first pitch value (1) 第 and the timbre value 112, and adding a harmonic waveform. The first timbre value 112 is tightly adjusted; it can be included in the adjustment process of the present invention, and the application of the present invention is not limited by the embodiment. In summary, it can be seen that the difference between the present invention and the prior art is that the first spectrum information obtained by analyzing the singer's voice signal is adjusted to different sound signals, and then the original sound signal and the adjusted sound signal are performed. Mixing, forming a new sound signal, and finally outputting the technical means of playing, by this technical means can solve the problems existing in the prior art, thereby achieving the technical effect that a single singer can achieve harmony singing through the invention. Although the embodiments of the present invention are as described above, the above description is not intended to directly limit the scope of the invention. Any changes in the form and details of the embodiments may be made without departing from the spirit and scope of the invention.
