Description

Voice Synthesis Service System and Control Method Thereof}

The present invention relates to a voice synthesis service system and a control method thereof, in particular to improve the quality of service by increasing the performance of a synthesis engine so that it is possible to more accurately understand a specific vocabulary in a sentence, such as when it is desired to hear a synthesized sentence again. A synthesis service system and a control method thereof.

Recently, many information service companies are introducing voice synthesis engines to make service systems intelligent, diversified and efficient.

1 is an exemplary view showing a configuration of a conventional speech synthesis service system, and as shown in FIG. 1, a speech synthesis engine generally used is previously used to synthesize a speech synthesized sound if it is not clear and wants to listen again. Synthesize speech using the same sentences.

However, this method has a problem of repeatedly listening to the same unclear synthesized sound as the previously synthesized synthesized sound, and high quality is maintained when synthesizing a frequently used vocabulary or sentence, but the intelligibility is significantly reduced in various fields. There are drawbacks, especially in the case of proper nouns such as trade names, person names, addresses and the like. In other words, there is no way to clarify the core specific vocabulary in the sentence more clearly, it is difficult to apply in a service that is used a lot of proper nouns.

Therefore, the present invention was devised to solve the above problems of the prior art, and when a compound sentence is sent to a synthesis engine, a method of expressing a method for reading a specific vocabulary in speech units can be expressed in the speech synthesis engine. The purpose of the present invention is to provide a system and method that allows the synthesized engine to pronounce the syllables only one syllable, making it easier to understand, and the synthesized engine to generate natural synthesized sounds in sentence units and syllable units.

The speech synthesis service system of the present invention for achieving the above object is a condition for requesting synthesis in syllable or sentence units according to the selection of the synthesis requirements by receiving a sentence to be synthesized with the speech synthesis service request and the A service scenario controller for outputting an input sentence; A sentence unit synthesizing unit that reads the speech data of the sentence unit stored in the sentence unit synthesis database and synthesizes the unit of sentence in case of synthesis in units of sentences according to the reading result of the synthesis requirement condition; And a syllable unit synthesis unit for synthesizing the syllable unit based on the result of the synthesis requirement and reading the syllable unit speech data stored in the syllable unit synthesis database and synthesizing the syllable unit to output the syllable unit synthesis unit. .

The control method includes: a synthesis selection step of selecting a synthesis requirement in syllable or sentence units when a sentence to be synthesized together with a voice synthesis service request is input as a service command; A synthesis request step of outputting condition data corresponding to the synthesis requirement condition and the input sentence according to the selection of the synthesis selection step; A synthesizing step of reading a synthesis requirement condition of the synthesis request step and performing a synthesis operation according thereto; Characterized in that the synthesized sound output step of outputting the synthesized sound synthesized in the synthesis performing step to the outside.

Hereinafter, with reference to the accompanying drawings an embodiment according to the present invention will be described in detail.

Figure 2 is an exemplary view showing the configuration of a speech synthesis system for applying the present invention. Referring to FIG. 2, a service scenario controller for receiving a sentence to be synthesized together with a voice synthesis service request, and outputting the input sentence and a condition for synthesizing the syllable or sentence unit according to the selection of the synthesis requirement; A service control unit (100) including a voice output unit (120) for outputting the synthesized sound synthesized finally according to the synthesis condition of the service scenario control unit (110); In the case of synthesizing in sentence units according to the reading result of the synthesis requirements, the sentence unit synthesizing unit 210 reads the speech data of the corresponding sentence units stored in the sentence unit synthesis database 220 and performs sentence unit synthesis to output the sentence unit synthesis unit 210. Wow; The syllable unit synthesizing unit 230 reads the speech data of the syllable unit stored in the syllable unit synthesis database 240 and synthesizes the syllable unit and outputs the syllable unit synthesized in syllable units according to the result of the synthesis requirement. It consists of a speech synthesis engine 200 comprising a.

Referring to the operation of the embodiment configured as described above are as follows.

First, Figure 3 is an exemplary view showing the operation of the service control unit according to the present invention, as shown in the service control unit 100 is a voice synthesis service in the service scenario control unit 110 when a service command is input from the outside Determine (S100 ~ S101).

If it is determined that the first step is not a voice synthesis service, a corresponding service process is performed (S012). In the case of a voice synthesis service, a synthesis request condition is selected after inputting a sentence (S103 to S104).

Condition data indicating syllable unit synthesis unit or sentence unit synthesis is generated according to the selection of the synthesis requirement condition, and output to the speech synthesis engine 200 (S105 to 107).

Subsequently, when condition data is input together with sentence input as shown in FIG. 4, the speech synthesis engine 200 determines whether the sentence unit is synthesized through reading (S200 to S202).

If the result of the determination in step S202 is not a sentence unit synthesis, the syllable unit synthesis unit performs a syllable unit synthesis process in the syllable unit synthesis unit 230 (S203). In the case of synthesis, the sentence unit synthesis unit 210 performs a sentence unit synthesis process (S204).

When the synthesis operation is performed, syllable unit or sentence unit synthesis is performed using syllable unit synthesis data and sentence unit voice data previously stored in the databases 220 and 240.

Then, after the execution of the step (S203) or step (S204) is completed, the speech synthesis engine 200 determines whether to continue the synthesis after connecting the synthesized sound (S205 ~ S206), this determination result According to it is performed repeatedly from the beginning or after the synthesis execution process and output to the service control unit 100 (S207).

Thereafter, as shown in FIG. 3, the service control unit 100 receives the synthesized sound and outputs it to the outside through the voice output unit 120, and then determines whether the service is terminated, and repeats the service from the beginning or terminates the service ( S108-S111).

As described above, the speech synthesis service system of the present invention and the method of controlling the same are described so that a method of reading a synthesized sentence with respect to a specific vocabulary is synthesized in syllable units so that the syllable is pronounced one syllable only for the marked vocabulary. In addition, it is possible to generate natural synthesized sounds in sentence units and syllable units using pre-stored voice data, thereby increasing the efficiency of the system.
