DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a technique for generating a pitch mode of synthesized sound. [Prior Art] The sound synthesizing device corresponding to the Chinese language is provided with a function of outputting the synthesized sound of the Chinese language according to the input pinyin (± the pronunciation of the Chinese word in Roman characters). >This day, Chinese language! The Chinese characters correspond to one syllable, and the syllables include: the foremost consonant called the consonant (the first consonant in the syllable), and the part called "the rhyme" that removes the "consonant" (vowel, double vowel, nasalization) Mother sound search). In order to be paid for the synthetic voice of the Chinese language, it is necessary to input the initials and the finals in Roman characters, but there are many Chinese characters with the same spell in Chinese. For example, if a certain syllable is "qi", there are "period", "odd", "start", ··· $ ' even if only the pinyin is lost, the conversion output candidate is not immediately available. ^^ Solve this problem' In combination with Pinyin, the input is used to indicate the syllable of the second syllable (the difference between the pitch and the pitch) (called the tone of the four sounds) (tune information). The tone is basically 匕3. Maintain the first sound of its pitch (the height of the sound), and increase the pitch _ 2. Temporarily lower the pitch and then increase the third sound and lower the pitch; ). When you turn in the sound of the sound of the field, you can add the first sound to the fourth sound, and then add the corresponding sound to the corresponding 4 to give the "period" (- the first suppression. List 1) "("一弟一荦", "奇奇" (= second voice), "起起" (= 95459.doc a^17〇2 in the case of an alternate, the system is divided. Thus, # is the first designation corresponding to the spell. Sound), "器" (== fourth sound) as the conversion output: the round is "qil", "qi2", rqi3", "qi4" 9 combined input tone information indicating the type of tone, in the Chinese characters of B [Patent Document 1] JP-A-61-27597 [Summary of the Invention] The pitch change of each syllable can be obtained according to the tone of the input, but 匡 ";: the relationship between the wide and the subsequent syllables ( For example, the sound of the syllable (4)::", and the subsequent syllable tone is "second sound", etc.), and the name of the g-direction changes unnaturally. To change the synonym of the sound... Bu's also need to freely change the pitch of the synthesized sound, etc. The situation of the death is described in the first purpose of the present invention. A kind of real frequency for two kinds of pitch pattern generation technology, the second item _. The pitch mode used by the cloth master changes to solve the above problems, too happy mouth ^ _ A #, 么月之曰The genre of the south mode generating device is based on the input character _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ From the above-mentioned texts 1 - Li - Ba Bei Cheng Yi Bei, the mother Lang obtains the reference pitch / fixed poor news, and the tone information indicating the type of tone; memory means, ,, the tone number, standard pitch Change mode, and change the standard pitch change kernel type ^ deformation ^ change mode corresponding to the memory; selection means, the eight-series self-received tone, that is, the tone information specifies the aforementioned tone number, and from the 95459.doc 1271702 syllable The tone information of the syllable or the tone information of the subsequent syllable, selecting any one of the aforementioned standard pitch change patterns or the aforementioned pitch pitch change patterns corresponding to the aforementioned tone number; and generating means, which are selected according to Any of the pitch change patterns and the pitch of the obtained syllables specify the information, and the pitch mode of the syllable is generated. "This structure is used as the tone information of the obtained syllables (such as "the first tone number, and The syllable information from the syllable before the syllable ❹ = (4) The syllable information of the syllable 'Select the Iraqi number corresponding to the tone number!; = MODE • The third pitch of the standard pitch change mode) or: Any of the modes of the deformation pitch change mode - Figure 8 and Figure 9). So because of the selection of the sound of the syllable, the pitch of the syllables before and after the syllable is changed. ^ U This is compared with the case of considering only the coffee type, and the more natural tree-like pitch pattern generating device is characterized by two texts: the poor news 'generates the pitch representing the temporal change of the synthesized sound corresponding to the text information.

As shown in Figure 2A, the text information r xianglgang3 (=Hong Kong) contains the text information of the 2 syllables with the sounds of "Sympic" and "Calling" (Hong Kong). Figure 2B shows the text information rcha 〇1(=^)__ren2(=仁)” is a two-syllable text containing the phonetic information “cha〇1(=super)_·” with the tone and long tone and the ninth syllable with the tone of the pinyin “ren2 (=ren)” News. In addition, the long note "_" means that the syllable in which the long note is present ("Bol" in Fig. 2) is only extended by a certain length, and the number of consecutive long notes is increased. The longer the pronunciation of the syllable is. In addition, the second type of text information contains text information of accent information. The accented poor news is attached to the corresponding syllables with information for suppressing, and includes accent marks such as "," "", or "3", "2", etc., which are added to the accent strength after the accent mark. Stress intensity (see Figure 3). As shown in Fig. 3A, the text information ye3 (second also) adds accent information 12 ye3" to the text information of a syllable with the tonal information "'2", 95459.doc -10- 1271702 The text information ", 3 ai - 2 · _, 4_" shown in B, is attached with accent information ", 3", "― 2" in the sound-changing and long-sounding pinyin "al (= Ah)..." The text of "4" is poor (see Figure 4). In the following, since the accent information will be described in detail later, the description is omitted here. The character analysis unit 220 analyzes the character information supplied from the input unit 21, and supplies the analysis result to the pitch generation unit 23() and the audio signal generation unit 240, respectively. When the character analysis unit (the acquisition means and the first acquisition means (10) from the input unit 2H) obtains the character information, the character information is divided into the syllables 2 to obtain the pitch indicating the syllable reference (for example). 2〇〇 (Hz), etc.) The pitch designation information, the rhythm information, and the prosody information indicating the size or length of the sound. Then, the character analysis unit 22() supplies the divided text information for each syllable to the character information type determination unit 231, and supplies the obtained pitch information specifying information for each syllable to the pitch pattern generation unit 236, and acquires each of the acquired The phonological information and the prosody information of the syllable are supplied to the audio signal generating unit "Ο. The text information type determining unit (detecting means) 2 3 丨 the text information of the phonological information supplied from the character analyzing unit 220 - the first type of text information or the first The second type of text information. The text information type determining unit 231 determines that the first type of text information is included when the text information does not include the accent information, and determines that it is the second when the text information includes the accent information. The character information type judging unit 231 supplies the first type of text tweet information tune information acquisition unit based on the determination result, and supplies the second type of character information to the weight: information acquisition unit 231b. Thus, the present embodiment (4) When accent stress is included in a syllable, the accent information is prioritized regardless of whether or not the syllable contains tone information, and the accent is based on the accent The processing is performed, but the accent information included in the syllable 95459.doc 1271702 is prioritized, or the tone information is prioritized, and can be appropriately changed according to the design of the voice synthesizing device 100. The tone information acquisition unit (acquisition means, second The acquisition means 231a obtains the tone information for each syllable from the first type of text, and supplies it to the tone/pitch change pattern generation unit 234a. The accent information acquisition unit 231b obtains the accent per tone from the second type of text information. The poor signal is supplied to the accent/pitch change pattern generation unit U. The tone/pitch change pattern generation unit 234a> the tone/pitch change pattern generation unit 234a includes the tone and the pitch change. Selection (selection means) 232a and tone/pitch change mode table (recording means) 233a. ~ Figure 5 shows the picture of the registration of the pitch/pitch change mode table 233a. In the table (memory means, second memory means) 233a, the tone number for each tone (the first to fourth sounds) is registered in correspondence with the pitch change mode tool. {High change mode The person who expresses the temporal pitch, the sub-inclusion: the standard sound meaning of the pitch change of the standard of each tone: the 杈 type (see the solid line part shown in Figure 8 and Figure 9), and the change of the corresponding private standard曰 夂 变形 变形 变形 变形 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( : 欠 曰〆, σ 凋 凋 讯 讯 凋 凋 凋 凋 凋 凋 凋 凋 凋 凋 凋 凋 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音 音2 and L «V + 曰 曰 — — — — 耳 耳 耳 — — — — 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 耳 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形 变形The pitch of the second sound of the sound of the sound is 95459.doc -12- 1271702 (details are described later). In addition, the following description will be based on the relationship between the tone of the previous syllable and the tone information of the syllable. The pitch change is called the morphological change mode, which will be based on the subsequent syllable information.

Therefore, the synthesized sound according to the pitch mode generated as described above is output to the outside via a speaker (omitted pattern) or the like. - as described above, the sound synthesizing device of the present embodiment selects the pitch change pattern of the pitch of the preceding and lower syllables in addition to the tone of the syllable, and compares it with the tone change mode in which only the pitch of the syllable is considered. I Get a synthetic sound that shows a more natural pitch change. In addition, in the case where the input text information contains accent information, an accent mark that does not show the stress of the accent and a pitch change pattern that reflects the intensity of the accent are generated. Thereby, it is possible to obtain a synthesized sound in which the pitch of the mode can not be expressed and the pitch of the user's desired pitch changes. MODIFICATION MODIFICATION <Modification 1> The above-described embodiment describes the case where the syllables of each syllable are classified into four sounds having four characteristic pitch changes, but the syllables of the Chinese (Mandarin) are used. There are also those in the tone that are called "soft" when they are not pronounced with a certain pitch change. These soft voices are only marked by the pinyin without the tone information ("xie4xie (=thank you)", etc.), and the soft voice can still maintain the pitch change mode of the previous syllable. In addition, this embodiment assumes Chinese, but it can also be applied to all languages having a tone such as Thai and Vietnamese. In addition, the above embodiment describes the case where the character is input by pinyin, but the character information can also be input by the Chinese character. At this time, the tone can be input using the tone information or the like in the same manner as the present embodiment. In addition, it is also prepared in advance to prepare a Chinese character and a tone table corresponding to each of the Chinese characters and the tones by reference. The Chinese character tone table specifies the tone of the input Chinese character. <Modification 2> Fig. 15 is a structural diagram showing the tone/pitch change pattern generation unit 234a' of the second modification. The tone/pitch change pattern generation unit 234a' includes a distortion pitch change pattern generation unit (generation means) 232a and a tone/pitch change pattern table (memory means) 233a. The tone/pitch change pattern table 233a shown in FIG. 5 is different in the tone/pitch change pattern table 233a, and the tone numbers and the respective tone numbers (first to fourth sounds) for each tone are specified. The standard pitch change mode of the standard pitch change of the tone is registered correspondingly, and is not registered corresponding to the modified pitch change mode. Further, the 'deformation pitch change pattern generation unit (generation means) 232a generates a deformation pitch change pattern by changing and passing from the tone/pitch change pattern table 233a and extracting the standard pitch change pattern ' (refer to Figure 8 and Figure 9 are the dotted lines). Specifically, the transformed pitch change pattern generation unit 232a first specifies the tone number based on the tone information supplied from the tone-of-mouth acquisition unit 231a. Then, the k-shaped two-change pattern generation unit 232a extracts a standard pitch change pattern corresponding to the designated tone number from the tone/pitch change pattern table 233a'. The transformed pitch change pattern generating unit 232a extracts the standard pitch change pattern 牯苓, the tone information of the syllable before the 5 hai lang (or the subsequent syllable tone) to determine whether or not the morphing change mode is generated. In addition, in order to make this decision, it is only necessary to refer to the memory of the principle (the shape principle) when the deformation pitch change mode is registered in advance. Deformation pitch change mode production 95459.doc 19 1271702 When the Ministry of Health 2 determines the deformation pitch change mode, refer to the deformation principle in the memory (omitted pattern) to change the standard tone. Change mode. In this manner, the transformed pitch change pattern generating unit 232a generates the 'k-shaped pitch change pattern shown in Fig. 8 and Fig. 9 and supplies it to the pitch mode, and produces a change of the pitch pitch. The operation of the mode generation unit 232aj, the deformation and the subsequent operation, can be described in the same manner as in the present embodiment, and thus the description thereof is omitted. <Modification 3> Further, the functions of the above-described voice synthesizing device i (10) are realized by a CPU (or DSP) executing a program stored in a memory such as R〇M or the like, so that the program can be recorded in It is distributed on recording media such as CD_R0M, and can also be distributed via a communication network such as the Internet.
