Initially connected to the voice output control module providing server 400 via the 300, and proceeds a series of subscription procedures, the voice output control module of the present invention in the information processing area of the self-owned mobile communication terminal 10 ( Download and install 100). In this case, the user-owned mobile communication terminal 10 may be, for example, a cellular phone, a PCS (Personal Communications Services phone), a synchronous / asynchronous IMT-2000 (International Mobile Telecommunication-2000), a smart phone. (Smart phone), WAP phone (WAP phone: Wireless application protocol phone) and the like can be flexibly selected.

On the other hand, as shown in Figure 2, the mobile communication terminal 10 in which the present invention is implemented is largely a series of input and output gates, for example, the microphone 4, the key input unit 2, the speaker 6, the display unit (3), a main body 1 provided with a back, a terminal control unit 11 embedded in the main body 1, a duplexer 16 forming a series of signal connection relationships with the terminal control unit 11, and a signal The combination of the transmitter 15, the frequency synthesizer 14, the signal receiver 13, and the voice output control module 100 inherent in the present invention to form another signal connection relationship with the terminal control unit 11 above. Is done.

At this time, the duplexer 16 outputs a signal received by the antenna 5 to the signal receiver 13, or outputs a signal output from the signal transmitter 15 to the external radio base station 201 through the antenna 5. The signal receiver 13 synthesizes a signal output from the duplexer 16 and a signal output from the frequency synthesizer 14, and then outputs the synthesized signal to the speaker 6. To perform.

In addition, the aforementioned frequency synthesizer 14 generates a separate frequency for removing a carrier frequency of a signal received by the frequency synthesizer 14, and outputs the frequency to the signal receiver 13, or transmits a separate frequency. It generates a carrier frequency, and outputs this transmission carrier frequency to the signal transmitter 15, the signal transmitter 15 transmits an electrical voice signal output from the microphone 101 to the terminal controller (11) In addition to performing the role, the transmission carrier output from the electric voice signal processed by the terminal control unit 11 and the voice output control module 100 according to the present invention and the previous frequency synthesizer 14 are processed. By synthesizing the frequencies, the synthesized signals are output to the duplexer 16.

At this time, the above-described signal transmitter 15, frequency synthesizer 14, signal receiver 13, and the like are all controlled by the aforementioned terminal controller 11, and finally, the terminal controller 11 receives the signal transmitter. (15), it is possible to arbitrarily adjust the operating states of the frequency synthesizer 14, the signal receiver 13 and the like.

Here, as shown in the figure, the terminal control unit 11 is connected to the signal transmitter 15, the frequency synthesizer 14, the signal receiver 13, as well as the data memory unit 12 in a series of signal connection relationship To form more. In this case, the data memory unit 12, together with the program for performing the overall operation of the device, the data generated by the operation of the program, etc., setting information related to the voice output set by the user, for example, "user's voice modulation / Background sound synthesis execution selection related information, user-specified voice modulation type related information, user-specified background sound type related information ...

On the other hand, as shown in the drawings, the voice output control module 100 unique to the present invention mentioned above is largely in the combination of the voice processing controller 101, the voice modulator 102, the background sound synthesizer 105, etc. Is done.

At this time, the voice processing controller 101 operates a user original voice input to the microphone 4 of the mobile communication terminal 10 under the control of the terminal control unit 11, and thus a series of voices targeted to the user original voice. The voice modulator 102 analyzes a user's original voice according to the control of the voice processing controller 101 and then performs a series of voices predetermined by the user. According to the modulation parameter, it plays a role of converting the user original voice into a series of modulated voices, for example, "high tone voice, low tone voice, robot voice, monster voice, ghost voice, echo voice ..." and the like. The synthesizing unit 105 selectively extracts a series of background sounds predetermined by the user, for example, "song, classical, Korean music, pop song .....", etc. under the control of the audio processing controller 101, and then the background sound. Selectively adjusting the level according to the user level of the original speech sound level or modulation of, and serve to synthesize a background noise level adjustment is completed the user won a voice or speech modulation.

Here, as shown in the figure, the voice output control module 100 of the present invention, as well as the above components, voice modulation parameter storage unit 103, voice feature extraction unit 104, background sound storage unit 108 ), A background sound extracting unit 107, a background sound level control unit 106, and the like are further disposed.

At this time, the voice modulation parameter storage unit 103 is used for various types of voice modulation reference parameters for guiding the voice modulation function performance of the voice modulation unit 102, for example, " reference parameters required for high tone voice modulation, low tone voice modulation. It stores the necessary reference parameters, reference parameters for robot voice modulation, reference parameters for monster voice modulation, reference parameters for ghost voice modulation, reference parameters required for echo voice modulation, and so on. The unit 104 performs the function of extracting the characteristics of the original user voice, for example, "user original voice amplitude, user original voice frequency ...", etc. under the control of the voice modulator 102 described above.

Further, the background sound storage unit 108 stores substantial background sound files necessary for the background sound synthesis of the background sound synthesis unit 105, for example, "song sound file, classic sound file, Korean music sound file, pop song sound file .." The background sound extractor 107 selectively extracts the background sound sound files stored in the background sound storage 108 under the control of the background sound synthesizer 105 described above. The background sound level control unit 106 controls the background sound sound level recorded in the background sound sound file, for example, the background sound sound frequency level, to the " level of the original user voice " or " level of the modulated voice " Substantially dedicated to the role of selective adjustment.

Hereinafter, the voice output control method unique to the present invention using the voice output control module 100 having the above-described configuration will be described in detail.

First, as shown in FIG. 3, at the start of a series of calls, the terminal controller 11 checks the data output from the signal transmitter 15 to determine whether or not a series of voice input events have occurred ( Step S1).

At this time, if the user using the mobile communication terminal 10 has not yet spoken and it is determined that no separate voice input event has occurred, the terminal control unit 11 proceeds to the flow to step S2, a series of standby Maintain state.

However, if the user using the mobile communication terminal 10 speaks through the microphone 4 and judges that a series of voice input events have occurred, the terminal control unit 11 immediately returns the data memory unit 12. Check the information related to the user's voice modulation / background sound synthesis execution selection, the user's pre-designated voice modulation type information, the user's pre-designated background sound type ........., and the like. It is determined whether the mode is the voice modulation / background sound synthesis combined execution mode (step S3).

At this time, if it is determined that the current terminal setting mode is not the voice modulation / background sound synthesis combined execution mode, the terminal control unit 11 proceeds to step S9 to describe the flow later.

However, if it is determined that the current terminal setting mode is the voice modulation / background sound combining / combining execution mode, the terminal control section 11 immediately returns "user original voice information", "user-specified voice modulation type related information", " Along with a user-specified background sound type related information ", etc., and transmits an instruction message" modulate the user's original voice and synthesize a background sound to the modulated voice "to the voice processing controller 101 of the voice output control module 100. (Step S5).

In this state, as illustrated in FIG. 4, the voice processing controller 101 continuously checks the instruction status of the terminal controller 11 to determine whether a series of voice modulation / background sound synthesis / coordination execution instruction events have occurred. (Step S101).

At this time, when it is determined from the terminal control section 11 that a series of voice modulation / background sound combining execution instruction events have occurred, the voice processing controller 101 immediately sends the " user original voice information " Information related to a voice modulation type designated by the user ", and the like, thereby instructing the progress of the predetermined voice modulation process.

In this instructional situation, the voice modulator 102 first controls the voice feature extractor 104 to proceed to extract the feature of the user's original voice (step S102). In this case, the voice feature extracting unit 104 extracts the characteristics of the user original voice, for example, "user original voice amplitude, user original voice frequency ..." etc. according to a predetermined extraction routine as shown in FIG. .

Next, the voice modulator 102 checks the " information related to the voice modulation type designated by the user " and, accordingly, checks the voice modulator parameter storage unit and selects, for example, ghosts among the voice modulator reference parameters previously stored therein. By selectively extracting the reference parameters required for voice modulation and processing the original user voice having the characteristics as shown in Fig. 5 to the frequency and amplitude as shown in Fig. 6 according to the reference parameters required for the ghost voice modulation. Then, the final modulated voice is generated (steps S103, S104, S105).

In general, the frequency, amplitude, and the like of the voice are the main variables for determining the tone, height, and the like of the voice. When the frequency and amplitude are changed, the finally generated modulated speech can stably retain its characteristics as, for example, a ghost speech.

Of course, since the voice modulator 102 of the present invention modulates only the tone and frequency of the voice and the frequency and amplitude of the voice, the modulated voice is not changed even if the original voice is converted to the modulated voice by the implementation of the present invention. It retains the pronunciation characteristics originally possessed by the user's original voice.

Thereafter, the voice modulator 102 transmits the generated modulated voice to the voice processing controller 101 through the above-described process.

On the other hand, when a series of modulated voices are returned from the voice modulator 102 through the above-described process, the voice processing controller 101 immediately returns the corresponding "modulated voices" and "users" to the background sound synthesizer 105. Pre-designated background sound type related information ”and the like, thereby instructing the progress of the predetermined background sound synthesis process.

Under such an instructional condition, the background sound synthesis unit 105 first checks the "background sound type related information predetermined by the user", and then controls the background sound extraction unit 107 to control the background sound previously stored in the background sound storage unit 108. Among the sound files, a process of selectively extracting a background sound sound file designated by the user is performed (step S106).

Subsequently, the background sound synthesis unit 105 transmits the background sound sound file and the modulated voice secured through the above process to the background sound level control unit 106, thereby instructing the progress of a series of "background sound level adjustment routines". In this case, the background sound level control unit 106 checks and confirms the level of the "modulated voice" transmitted from the background sound synthesis unit 105, for example, the frequency level of the modulated voice, and then adjusts the background sound sound frequency level recorded in the background sound sound file. Adjustment is appropriately made in accordance with the frequency level of the modulated voice (steps S107, S108).

According to the background sound sound frequency level adjustment process, for example, the background sound that forms the background of the modulated voice has a frequency level that does not interfere with the transmission of the modulated voice.

Through the above process, when the frequency level adjustment of the background sound is completed, the background sound synthesis unit 105 immediately synthesizes the previous modulated voice and the background sound whose frequency level adjustment is completed, and generates the final processed voice. The process of transferring to the voice processing controller 101 is performed (step S109).

Through the above-described process, when a series of processed voices is returned from the background sound synthesis unit 105, the voice processing controller 101 immediately proceeds to return the corresponding processed voices to the terminal control unit 11 (step S110). ).

On the other hand, corresponding to the aforementioned staff, as shown in Fig. 3, the terminal controller 11 determines whether or not a series of processed voices is returned from the voice processing controller 101 (step S6).

At this time, if the voice processing controller 101 does not finish each of the aforementioned steps, and it is determined from the voice processing controller 101 that the processing voice has not been returned yet, the terminal controller 11 proceeds to the flow at step S7. To maintain a series of standby states.

However, when the voice processing controller 101 finishes each of the above-mentioned steps and determines that a series of processed voices are returned from the voice processing controller 101, the terminal controller 11 immediately returns the processed voices. The signal transmitter 15 synthesizes the processed voice with the transmission carrier frequency output from the frequency synthesizer 14 as soon as the processed voice is transmitted from the terminal controller 11. This synthesized signal is output to the tuplexer 16, and the tuplexer 16 transmits the synthesized signal to an external mobile communication terminal 500 through the antenna 5 and the wireless base station 201 ( Step S8). As a result, the mobile communication terminal 500 allows the other party to talk with the user, for example, to hear the user's voice modulated by a series of ghost voice with the background sound.

As described above, in the case of the present invention, the information processing area of the mobile communication terminal 10 is, for example, "a series of modules capable of selectively modulating the voice of the user output to the other side according to the user's preset contents", " Software installed on the user's voice output to the other party, and a series of modules capable of selectively synthesizing the background sound selected by the user. By allowing the background sound to be inserted into the user's voice output to the other party, the user modulates his / her voice to the other party for entertainment purposes without installing a separate hardware device. Desire to make "," modulate your voice for the purpose of hiding your identity The synthesis of a series of jingles in his speech to call the process the purpose and desire, "" improve call the atmosphere you want to continue to be able to encourage easily be met such as the desire to push forward a series of calls the process ".

On the other hand, in step S4 mentioned above, if it is determined that the current terminal setting mode is not the voice modulation / background sound synthesis associated execution mode, the terminal control unit 11 once more whether the current terminal setting mode is the voice modulation alone execution mode. It judges (step S9).

At this time, if it is determined that the current terminal setting mode is the voice modulation single execution mode, the terminal control section 11 immediately returns the user with the "user original voice information", "user-specified voice modulation type related information", and the like. Modulate the original voice " to the voice processing controller 101 of the voice output control module 100 (step S10).

In response to the above-mentioned staff, as shown in FIG. 4, the voice processing controller 101 continuously checks the instruction status of the terminal controller 11 to determine whether a series of voice modulation single execution instruction events have occurred. It is judged whether or not (step S111).

At this time, when it is determined that the series of voice modulation single execution instruction event has occurred from the terminal controller 11, the voice processing controller 101 immediately sends the " user original voice information " Information related to the designated voice modulation type ", and the like, thereby instructing the progress of the predetermined voice modulation process.

In this instructional situation, the voice modulator 102 first controls the voice feature extractor 104 to proceed to extract the feature of the user's original voice (step S112). In this case, the speech feature extracting section extracts the characteristics of the user original speech, for example, "user original speech amplitude, user original speech frequency ..." etc. according to a predetermined extraction routine as shown in FIG.

Next, the voice modulator 102 checks the "user-specified information related to the voice modulation type," and accordingly, checks the voice modulation parameter storage unit 103 and stores the voice modulation reference parameters previously stored therein. Among them, for example, the reference parameters required for the robot voice modulation are selectively extracted, and according to the reference parameters required for the robot voice modulation, the user original voice having the characteristics as shown in FIG. By processing the amplitude, the final modulated voice is generated (steps S113, S114, S115).

Of course, even in this case, since the voice modulator of the present invention modulates only the tone and frequency of the voice and the frequency and amplitude of the voice, even if the original voice is converted into the modulated voice by the implementation of the present invention, the modulated voice is It retains the pronunciation characteristics originally possessed by the user's original voice.

Thereafter, the voice modulator 102 transmits the generated modulated voice to the voice processing controller 101 through the above-described process.

Through the above-described process, when a series of modulated voices is returned from the voice modulator 102, the voice processing controller 101 immediately proceeds to return the modulated voices to the terminal controller 11 (step S116). ).

Meanwhile, in response to the above-mentioned step, as shown in FIG. 3, the terminal controller 11 determines whether a series of modulated voices are returned from the voice processing controller 101 (step S11).

At this time, if the voice processing controller 101 does not finish each of the above-mentioned steps, and it is determined from the voice processing controller 101 that no modulated voice is returned yet, the terminal controller 11 proceeds to the flow at step S12. To maintain a series of standby states.

However, when the voice processing controller 101 finishes all the above-mentioned steps and determines that a series of modulated voices are returned from the voice processing controller 101, the terminal control unit 11 immediately returns the modulated voices. The signal transmitter 15 transmits the modulated voice to the signal transmitter 15 immediately after the modulated voice is transmitted from the terminal controller 11, and synthesizes the modulated voice with the transmission carrier frequency output from the frequency synthesizer 14. This synthesized signal is output to the tuplexer 16, and the tuplexer 16 transmits the synthesized signal to an external mobile communication terminal 500 through the antenna 5 and the wireless base station 201 ( Step S13). As a result, through the mobile communication terminal 500, the other party talking to the user can hear the user's voice modulated by, for example, a series of robot voices.

On the other hand, in the aforementioned step S9, if it is determined that the current terminal setting mode is not the voice modulation single execution mode, the terminal controller 11 determines once more whether the current terminal setting mode is the background sound synthesis alone execution mode ( Step S14).

At this time, if the current terminal setting mode is not the background sound synthesis alone execution mode, the terminal control unit 11 proceeds with the normal " user original voice output process " (step S15).

However, if it is determined that the current terminal setting mode is the background sound synthesis alone execution mode, the terminal control unit 11 immediately returns the "user source" together with "user original voice information", "background tone type predetermined information specified by the user", and the like. Synthesize the background sound to the voice "is transmitted to the voice processing controller 101 of the voice output control module 100 side (step S16).

In response to the above-mentioned staff, as shown in FIG. 4, the voice processing controller 101 continuously checks the instruction status of the terminal controller 11 to determine whether a series of background sound synthesis solo execution instruction events have occurred. It is judged whether or not (step S117).

At this time, if it is determined that the separate background sound synthesis alone execution instruction event has not occurred from the terminal controller 11, the voice processing controller 101 returns, for example, the flow to the beginning.

However, if it is determined from the terminal controller 11 that a series of background sound synthesis alone execution instruction events have occurred, the voice processing controller 101 immediately sends the corresponding "user original voice" and "user" to the background sound synthesis unit 105 side. Information related to the designated background sound type ", and the like, thereby instructing the progress of the predetermined background sound synthesis process.

Under such an instructional condition, the background sound synthesis unit 105 first checks the "background sound type related information predetermined by the user", and then controls the background sound extraction unit 107 to control the background sound previously stored in the background sound storage unit 108. Among the sound files, a process of selectively extracting a background sound sound file designated by the user is performed (step S118).

Subsequently, the background sound synthesis unit 105 delivers the background sound sound file and the original user sound obtained through the above process to the background sound level control unit 106, thereby instructing the progress of a series of "background sound level adjustment routines". . In this case, the background sound level control unit 106 checks and confirms the level of the "user original voice" transmitted from the background sound synthesis unit 105, for example, the frequency level of the user original voice, and then the background sound sound frequency recorded in the background sound sound file. The level is appropriately adjusted in accordance with the frequency level of the user's original voice (steps S119 and S120).

According to this background sound sound frequency level adjustment process, for example, the background sound that forms the background of the user's original voice has a frequency level that does not interfere with the transmission of the user's original voice.

Through the above process, when the frequency level adjustment of the background sound is completed, the background sound synthesizing unit 105 immediately synthesizes the original original voice and the background sound whose frequency level adjustment is completed to generate the final synthesized voice, This is transmitted to the voice processing controller 101 (step S121).

Through the above-described process, when a series of synthesized voices are returned from the background sound synthesizer 105, the voice processing controller 101 immediately proceeds to return the synthesized voices to the terminal controller 11 (step S122). ).

Meanwhile, in response to the above-mentioned step, as shown in FIG. 3, the terminal controller 11 determines whether or not a series of synthesized voices are returned from the voice processing controller 101 (step S17).

At this time, if the voice processing controller 101 does not finish each of the above-mentioned steps, and it is determined from the voice processing controller 101 that the synthesized voice has not been returned yet, the terminal controller 11 proceeds to the flow at step S18. To maintain a series of standby states.

However, when the voice processing controller 101 finishes all the above-mentioned steps and determines that a series of synthesized voices are returned from the voice processing controller 101, the terminal control unit 11 immediately returns the synthesized voices. When the synthesized voice is transmitted from the terminal controller 11, the signal transmitter 15 synthesizes the synthesized voice with the transmission carrier frequency output from the frequency synthesizer 14. This synthesized signal is output to the tuplexer 16, and the tuplexer 16 transmits the synthesized signal to an external mobile communication terminal 500 through the antenna 5 and the wireless base station 201 ( In step S19), through the mobile communication terminal 500, the other party talking to the user can, for example, hear the original voice of the user together with the background sound.

Thereafter, when the other party's voice signal is received by the antenna 5, the duplexer 16 transmits the signal to the signal receiver 13, and the signal receiver 13 transmits the voice signal from the frequency synthesizer 14. This synthesized signal is output to the speaker 6 in combination with the corrected frequency to be output. As a result, the user can quickly proceed with a smooth call process desired by the user.

As described in detail above, in the present invention, in the information processing area of the mobile communication terminal, for example, "a series of modules that can selectively modulate the user's voice output to the other side according to the user's preset contents", "the other party. Software installed on the user's voice output to the user side, and a series of modules capable of selectively synthesizing a series of background sounds selected by the user. Voices, low tone voices, robot voices, monster voices, ghost voices, echo voices, etc., or to the user's voices output to the other party, for example, "K-Pop, Classical, Korean Music, Pop Songs ..." By inserting the background sound of the user, without the need for the user to install a separate hardware device, "for entertainment purposes The desire to proceed with a series of call processes by modulating his / her voice to the other party, "The desire to proceed with a series of call processes by modulating his / her voice for the purpose of concealing his / her identity to the uncomfortable party", "Call atmosphere For the purpose of improvement, a series of background sounds can be synthesized with one's own voice so that it can be easily met.
