Description

  The present invention relates to an information display control device with a voice output function having a function of outputting a reading voice corresponding to a headword displayed by dictionary search, for example, and a control program therefor.

  In the conventional electronic devices, various devices that output a read-out sound of the displayed text have been proposed.

  For example, one of them is a text-to-speech control program that is installed and functioning on a personal computer or the like, and synthesizes pre-stored speech corresponding to the characters of each word displayed in text and sequentially outputs them. There is.

  In this text-to-speech control process, if a synthesized speech corresponding to each character of a word to be read out is simply output, for example, in the case of Japanese “Haru”, words of different parts of speech are spelled even if the same character is spelled. The position of the accent is different between "Ha" and "Ru" between "Spring (noun)" and "Paste (verb)".

For this reason, a word accent determination method has been considered in which sentences before and after a speech output target word are grammatically analyzed to detect the part of speech, and can be output as a correct accent reading speech (for example, Patent Documents). 1).
Japanese Patent Application Laid-Open No. 07-140995

  In the conventional electronic device, the word accent determination method for properly functioning the text-to-speech voice output is based on the part-of-speech by detecting the part-of-speech by analyzing the sentences before and after the voice-output target word. Since different accent positions can be output correctly by voice, when speech is output for words that exist as phrases, command sentences, or words that exist alone, the correct part of speech cannot be detected and is correct. Sound output of pronunciation may not be performed.

  The present invention has been made in view of such a problem. When an arbitrary word is specified and its speech is output, it is possible to accurately output a word with different pronunciation due to a difference in part of speech.

  FIG. 5 is a flowchart showing the overall processing of dictionary search processing with voice output by the portable device (electronic dictionary) 10.

  FIG. 6 is a diagram showing a display operation corresponding to a key operation accompanying the dictionary search process with voice output of the portable device (electronic dictionary) 10.

  In the input unit 16, for example, as shown in FIG. 6A, when a “dictionary” key (for example, “English-Japanese” key 14a) of the type used for this dictionary search is input, the “dictionary” key is input. A search character input screen G1 corresponding to the corresponding type of “English-Japanese dictionary” is displayed on the display unit 17 (step S1).

  In this search character input screen G1, when a character string to be searched is input according to the operation of the character input key in the input unit 16, and stored in the input character memory 12c1 and displayed (step S1), this input character string The headword having the first character string that matches is searched from the “English-Japanese dictionary” dictionary data 12b1 and displayed on the display unit 17 as a headword list screen (not shown) (step S2).

  Then, in the display state of this headword list screen (not shown), the reverse cursor K is moved and displayed between the headwords according to the operation of the up and down cursor keys, and the headword desired by the user is selected. When the “translation / decision” key 14b is operated in the designated state (step S3), the explanation information corresponding to the selected entry word is read from the dictionary data 12b1 of the “English-Japanese dictionary”, As shown in FIG. 6A, it is displayed on the display unit 17 as an explanation information display screen G2 divided for each meaning classification (part of speech / meaning number) (step S4).

  In the explanation information display screen G2 for the headword (word) selected by the user, as shown in FIG. 6B, the “voice” key 14c is operated to learn the pronunciation of the selected word. At the same time (step S5), any word or idiom in the explanation information (sung phrase, idiom, idiomatic phrase, etc.) is designated by the moving display of the reverse cursor K in response to the operation of the cursor key 14d (in this case, search When the “translation / decision” key 14b is operated (step S6), the process shifts to word voice output processing described later in FIGS. 7 to 11 (step S6). In step S7 → SA), a speech synthesis command corresponding to the user-specified word (noun “record”) is generated and subjected to speech output processing by the speech synthesis engine 21.

  In addition, in the explanation information display screen G2 of the entry word (word) selected by the user, the “voice” key 14c is operated (step S5), and any idiom (spoken phrase, idiom, When the “translation / decision” key 14b is operated (step S6), the process proceeds to example sentence voice output processing described in FIGS. 12 to 16 (step S7 → SB). A voice synthesis command corresponding to the user-specified idiom is generated and voice output processing is performed by the voice synthesis engine 21.

  On the other hand, in the explanation information display screen G2 of the entry word (word) selected by the user, as shown in FIG. 6C, an “example sentence” key 14e is used to learn an example sentence using the selected word. Is operated (step S8), a list of example sentences of the desired meaning classification selected in accordance with the operation of the cursor key 14d is displayed (step S9).

  Then, in the example sentence list display state of the desired meaning classification, the “speech” key 14c is operated to learn the pronunciation of any example sentence (step S10), and any example sentence (in this case, the example sentence in the meaning 2) When "I-ed the show on tape.") Is designated and displayed by the reverse cursor K in response to the operation of the cursor key 14d (step S11), the processing proceeds to example sentence voice output processing described in FIGS. Then, a speech synthesis command corresponding to the example sentence “I to ed the show on tape.” Using the user-specified verb “record” is generated, and the speech synthesis engine 21 performs speech output processing.

  FIG. 7 is a flowchart showing word speech output processing (step SA) accompanying the dictionary search processing with speech output of the portable device (electronic dictionary) 10.

  FIG. 8 is a flowchart showing a word: part-of-speech correspondence process (step AC) for generating a speech synthesis command from the part-of-speech information of the designated word in accordance with the word speech output process (step SA) of the portable device (electronic dictionary) 10. is there.

  FIG. 9 is an explanatory information display screen on which a part-of-speech symbol of a designated word exists when a word: part-of-speech correspondence process (step AC) is started in association with the word voice output process (step SA) of the portable device (electronic dictionary) 10. It is a figure explaining the example of concrete production | generation of G2 and the word speech synthesis command based on this.

For example, as shown in FIG. 9, the English word “lead” is searched, and as shown in FIG. 9A, the verb “lead ¹ ” in the explanation information display screen G2 is used as the voice output target word. When the word voice output process in FIG. 7 is started by being designated (steps S1 to S7 → SA), first, the designated word “lead ¹ ” is the headword on the explanation information display screen G2. (Step A1).

  Here, when it is determined that the designated word that is the voice output target is the headword on the explanation information display screen G2, the explanation information that is behind the position of the designated word is searched (step A1). → A2) If it is determined that the designated word is not a headword on the explanation information display screen G2, explanation information ahead from the position of the designated word is searched (step A1 → A3). Then, it is determined whether or not the part of speech information of the designated word exists (step A4).

In this case, as shown in FIG. 9A, since the designated word “lead ¹ ” is determined to be a headword on the explanation information display screen G2 (step A1 (Yes)), the designated word The explanation information behind the position is searched (step A2), and the verb part-of-speech symbol “movement” M stored in the dictionary name / part of speech / command table 12b3 (see FIG. 3) exists. Judgment is made (step A4 (Yes)). Then, the process proceeds to the word: part of speech correspondence process (step AC) in FIG.

When this word: part of speech correspondence processing is started, the dictionary name / part of speech / command table is used in accordance with the verb “part of speech” M obtained from the explanation information (G2) of the designated word “lead ¹ ”. An additional command code [<pron> verb] for speech synthesis is determined from 12b3 (see FIG. 3) (step C1), and is added before the designated word text “lead ¹ ”, which is a speech output target, so that the word speech synthesis is performed. The command “[<pron> verb] lead ¹ ” is generated (step C2).

Then, the word speech synthesis command “[<pron> verb] lead ¹ ” of the verb “lead ¹ ”, which is the designated word generated according to the part of speech symbol “movement” M, is sent to the speech synthesis engine 21. (Step C3), the speech synthesis engine 21 generates a word speech signal of pronunciation “lead” corresponding to the verb “lead ¹ ” and outputs it from the speaker 18 (steps AC → A7, A8).

On the other hand, as shown in FIG. 9B, when the “lead ² ” noun in the explanation information display screen G2 for “lead” is designated as a word to be output, the dictionary name / part of speech / command table It is determined that “name” N which is a part of speech symbol stored in 12b3 (see FIG. 3) is present (step A4 (Yes)), and the word: part of speech correspondence processing (step AC) in FIG. To be migrated.

Then, according to “name” N which is the part of speech symbol of the noun obtained from the explanation information (G2) of the designated word “lead ² ”, the dictionary name / part of speech / command table 12b3 (see FIG. 3) is used for speech synthesis. The additional command code [<pron> noun] is determined (step C1), and is added before the designated word text “lead ² ” which is the speech output target to be added to the word speech synthesis command “[<pron> noun] lead ^2”. Is generated (step C2).

Then, the word speech synthesis command “[<pron> noun] lead ² ” of the noun “lead ² ” which is the designated word generated according to the part of speech symbol “name” N is sent to the speech synthesis engine 21. (Step C3) The speech synthesis engine 21 generates a word speech signal of pronunciation “red” corresponding to the noun “lead ² ” and outputs it from the speaker 18 (steps AC → A7, A8).

For example, in the case of the designated word “lead ¹ ”, the noun may be pronounced as “lead”. In this case, the part of speech symbol “name” of the noun is preceded by the designated word text “lead ¹ ”. Since the additional command code [<pron> noun] determined according to N is added and the word speech synthesis command “[<pron> noun] lead ¹ ” is generated, the synthesized speech engine 21 provides the given word speech synthesis. additional description of the command is a noun command code [<pron> noun] word text also have a "lead ^1" noun by detecting a ^"1" added the number to the end of the corresponding to "lead ^1" Generate and output an audio signal of the pronunciation “Lead”.

  FIG. 10 is a flowchart showing a word: phonetic symbol correspondence process (step AD) for generating a speech synthesis command from a phonetic symbol of a designated word in accordance with the word voice output process (step SA) of the portable device (electronic dictionary) 10. It is.

  FIG. 11 is an explanatory information display in which a phonetic symbol of a designated word exists when a word: phonetic symbol correspondence processing (step AD) is started in accordance with the word voice output processing (step SA) of the portable device (electronic dictionary) 10. It is a figure explaining the specific production | generation example of the screen G2 and the word speech synthesis command based on this.

For example, as shown in FIG. 11 (A), even when searching the explanation information (G2) of the designated word “lead ¹ ”, the part of speech information does not exist (steps A1 to A4 (No)), If it is determined that the symbol “li: d” exists (step A5 (Yes)), the process proceeds to the word: phonetic symbol correspondence process (step AD) in FIG.

When this word: phonetic symbol correspondence process is activated, the phonetic symbol conversion table 12b4 (corresponding to the phonetic symbol “li: d” obtained from the explanation information (G2) of the designated word “lead ¹ ”. The phonetic symbol command [liyd] for the speech synthesis engine 21 is determined (see FIG. 4) (step D1), and the designated word text “lead ¹ ”, which is the target of speech output, is determined in advance before the phonetic symbol command [liyd]. The phonetic symbol use command [<phoneme> ON] is added to the phonetic phonetic symbol command [<phoneme> ON] [liyd] (step D2).

Then, the word phonetic phonetic command [<phoneme> ON] [liyd] of the verb “lead ¹ ”, which is the designated word generated according to the phonetic symbol “li: d” in the explanation information, is sent to the speech synthesis engine 21. By being transmitted (step D3), the speech synthesis engine 21 generates a word speech signal of pronunciation “lead” corresponding to the verb “lead ¹ ” and outputs it from the speaker 18 (steps AD → A7, A8). ).

On the other hand, for example, as shown in FIG. 11B, the part of speech information does not exist even if the description information (G2) of the designated word “lead ² ” is searched (steps A1 to A4 (No)). ), It is determined that the phonetic symbol “led” exists (step A5 (Yes)), and when the processing proceeds to the word: phonetic symbol correspondence processing (step AD) in FIG. 10, the designated word “lead ² ” Corresponding to the phonetic symbol “led” obtained from the explanation information (G2), the phonetic symbol command [lehd] for the speech synthesis engine 21 is determined from the phonetic symbol conversion table 12b4 (see FIG. 4) (step D1). .

Then, the specified word text “lead ² ”, which is a voice output target, has a word phonetic symbol command [<phoneme> with a predetermined phonetic symbol use command [<phoneme> ON] added before the phonetic symbol command [lehd]. ON] [lehd] is generated (step D2).

Then, the phonetic symbol command [<phoneme> ON] [lehd] of the noun “lead ² ”, which is the designated word generated according to the phonetic symbol “led” in the explanation information, is sent to the speech synthesis engine 21. Thus (step D3), the speech synthesis engine 21 generates a word speech signal of pronunciation “red” corresponding to the noun “lead ² ” and outputs it from the speaker 18 (steps AD → A7, A8).

  As a result, even if the designated word to be output is a verb and a noun, the speech synthesis engine 21 according to the part-of-speech symbol or phonetic symbol present in the explanation information of the designated word. Therefore, it is possible to generate a voice output command corresponding to each of the voices, so that different pronunciation sounds depending on the part of speech can be output accurately and the user can learn without error.

  On the other hand, when it is determined that neither the part-of-speech information of the word nor the phonetic symbol is present in the explanation information of the designated word to be output (steps A1 to A5 (No)), The word text is sent to the speech synthesis engine 21 as it is, and synthesized speech corresponding to each character of the word text is generated and output from the speaker 18 as a pronunciation sound of one word (steps A6 to A8).

  FIG. 12 is a flowchart showing an example sentence voice output process (step SB) accompanying the dictionary search process with voice output of the portable device (electronic dictionary) 10.

  FIG. 13 shows an example sentence: part-of-speech correspondence process (step BE) for generating a speech synthesis command from the part-of-speech information of the meaning classification of the specified example sentence accompanying the example sentence voice output process (step SB) of the portable device (electronic dictionary) 10. It is a flowchart to show.

  FIG. 14 shows a part-of-speech symbol of a headword in a specified example sentence when an example sentence: part-of-speech correspondence process (step BE) is started in accordance with the example sentence voice output process (step SB) of the portable device (electronic dictionary) 10. It is a figure explaining the specific production | generation example of the description information display screen G2 and the example sentence speech synthesis command based on this.

For example, as shown in FIG. 14, the English word “lead” is searched, and as shown in FIG. 14 (A2), the example sentence “lead a horse by” of the verb “lead ¹ ” in the explanation information display screen G2 is searched. When the example sentence speech output process in FIG. 12 is started by designating “the bridle” as a speech output target example sentence (steps S1 to S4, S8 to S11 → SB), first, the designated example sentence “lead a A part-of-speech symbol is detected from the meaning classification in the explanation information of “horse by the bridle” (step B1), and the presence / absence of the part-of-speech symbol of the headword being searched is determined (step B2).

  Here, as shown in FIG. 14A, when it is determined that the part-of-speech symbol “movement” M is detected from the meaning classification in the explanation information having the designated example sentence “lead a horse by the bridle” (step B2 ( Yes)), the process proceeds to the example sentence in FIG. 13: part-of-speech correspondence process (step BE).

This example: When the part-of-speech correspondence processing is activated, the dictionary name is determined according to the verb part-of-speech symbol “movement” M obtained from the description information (G2) of the specified example sentence “lead a horse by the bridle”. -An additional command code [<pron> verb] for speech synthesis is determined from the part-of-speech / command table 12b3 (see FIG. 3) (step E1), and the designated example sentence text "lead a horse by the bridle" that is the target of speech output An example sentence speech synthesis command "[<pron> verb] lead ¹ a horse by the bridle" is added before the headword "lead" (or "~" mark) written in emphasis or italic letters Is generated (step E2).

Then, the example sentence speech synthesis command “[<pron> verb] lead ¹ a” corresponding to the example sentence “lead a horse by the bridle” including the verb headword “lead ¹ ” generated according to the part of speech symbol “movement” M. By sending “horse by the bridle” to the speech synthesis engine 21 (step E3), the speech synthesis engine 21 generates a speech signal of a specified example sentence including the pronunciation “lead” corresponding to the verb “lead ¹ ”. Generated and output from the speaker 18 (steps BE → B6, B7).

On the other hand, as shown in FIG. 14 (B2), the example sentence “a lead pipe” of the noun “lead ² ” in the explanation information display screen G2 of the search headword “lead” is designated as an example sentence for voice output. Then, when the example sentence voice output process in FIG. 12 is activated (steps S1 to S4, S8 to S11 → SB), as shown in FIG. 14 (B1), there is explanatory information with the specified example sentence “a lead pipe”. If it is determined that the part-of-speech symbol “name” N is detected from the meaning classification in FIG. 13 (step B2 (Yes)), the process proceeds to the example sentence: part-of-speech correspondence process (step BE) in FIG.

This example sentence: When the part-of-speech correspondence processing is activated, the dictionary name, part-of-speech, An additional command code [<pron> noun] for speech synthesis is determined from the command table 12b3 (see FIG. 3) (step E1), and the emphasis and italic characters of the designated example sentence text “a lead pipe” that is the target of speech output The example sentence speech synthesis command “a [<pron> noun] lead ² pipe” is generated before the head word “lead” (or “˜” mark) described in the above (step E2).

Then, the example sentence speech synthesis command “a [<pron> noun] lead ² pipe” corresponding to the example sentence “a lead pipe” including the headword “lead ² ” of the noun generated according to the part of speech symbol “name” N is By being sent to the speech synthesis engine 21 (step E3), the speech synthesis engine 21 generates a speech signal of a specified example sentence including the pronunciation “red” corresponding to the noun “lead ² ” and outputs it from the speaker 18. (Steps BE → B6, B7).

  FIG. 15 shows an example sentence: phonetic symbol correspondence process (step BF) for generating a speech synthesis command from a headword pronunciation symbol of a specified example sentence accompanying the example sentence voice output process (step SB) of the portable device (electronic dictionary) 10. It is a flowchart which shows.

  FIG. 16 shows the pronunciation symbol of the headword in the specified example sentence when the example sentence: phonetic symbol correspondence process (step BF) is started in accordance with the example sentence voice output process (step SB) of the portable device (electronic dictionary) 10. It is a figure explaining the specific production | generation example of the explanatory information display screen G2 to be performed, and the example sentence speech synthesis command based on this.

For example, as shown in FIG. 16 (A2), the example sentence “lead a horse by the bridle” of the verb “lead ¹ ” in the explanation information display screen G2 of the search head word “lead” is designated as an example sentence for voice output. Thus, when the example sentence voice output process in FIG. 12 is started (steps S1 to S4, S8 to S11 → SB), the part of speech is determined from the meaning classification in the explanation information of the designated example sentence “lead a horse by the bridle”. When no symbol is detected (steps B1 and B2 (No)), as shown in FIG. 16A1, it is determined that the phonetic symbol “li: d” exists by a forward search of the explanation information ( Steps B3 and B4 (Yes)), the process proceeds to the example sentence: phonetic symbol correspondence process (Step BF) in FIG.

  This example: When the phonetic symbol handling process is activated, the phonetic pronunciation corresponding to the phonetic symbol “li: d” obtained from the explanation information (G2) of the specified example sentence “lead a horse by the bridle” The phonetic symbol command [liyd] for the speech synthesis engine 21 is determined from the symbol conversion table 12b4 (see FIG. 4) (step F1). Then, the designated example sentence text “lead a horse by the bridle”, which is a voice output target, uses a predetermined phonetic symbol use command [<phoneme> ON] + the phonetic symbol command [liyd] ] Is generated as an example phonetic phonetic symbol command “[<phoneme> ON] [liyd] a horse by the bridle” (step F2).

Then, the example speech synthesis command “[<phoneme>” corresponding to the example sentence “lead a horse by the bridle” including the verb headword “lead ¹ ” generated according to the phonetic symbol “li: d” in the explanation information "ON] [liyd] a horse by the bridle" is sent to the speech synthesis engine 21 (step F3), and the speech synthesis engine 21 includes the pronunciation "lead" corresponding to the verb "lead ¹ " Is generated and output from the speaker 18 (steps BF → B6, B7).

On the other hand, as shown in FIG. 16 (B2), the example sentence “a lead pipe” of the noun “lead ² ” in the explanation information display screen G2 of the search headword “lead” is designated as an example sentence for voice output. Then, when the example sentence voice output process in FIG. 12 is activated (steps S1 to S4, S8 to S11 → SB), the part of speech symbol is detected from the meaning classification in the explanatory information with the designated example sentence “a lead pipe”. (Steps B1 and B2 (No)), as shown in FIG. 16 (B1), if it is determined that the phonetic symbol “led” exists by forward search of the explanation information (Steps B3 and B4 (Yes) )), The flow proceeds to the example sentence: phonetic symbol correspondence process (step BF) in FIG.

  This example: When the phonetic symbol correspondence process is started, the phonetic symbol conversion table 12b4 (in correspondence with the phonetic symbol “led” obtained from the explanation information (G2) of the specified example sentence “a lead pipe”. The phonetic symbol command [lehd] for the speech synthesis engine 21 is determined from (see FIG. 4) (step F1). Then, the specified example sentence text “a lead pipe”, which is a voice output target, converts the headword “lead” part into a predetermined phonetic symbol use command [<phoneme> ON] + the phonetic symbol command [lehd] An example sentence phonetic symbol command “a [<phoneme> ON] [lehd] pipe” is generated (step F2).

Then, the example sentence speech synthesis command “a [<phoneme> ON] [lehd” corresponding to the example sentence “a lead pipe” containing the noun “lead ² ” of the noun generated according to the phonetic symbol “led” in the explanation information ] pipe "is sent to the speech synthesis engine 21 (step F3), and the speech synthesis engine 21 generates a speech signal of a specified example sentence including the pronunciation" red "corresponding to the noun" lead ² ". Output from the speaker 18 (steps BF → B6, B7).

  As a result, even if the search headword included in the designated example sentence to be output is different in pronunciation from a verb and a noun, the headword that exists in the explanation information of the designated example sentence According to the part-of-speech symbol or the phonetic symbol of the word, the corresponding example sentence voice output command to the speech synthesis engine 21 can be generated. You can learn.

  On the other hand, if it is determined that neither the part-of-speech information of the entry word nor the phonetic symbol is present in the entry word explanation information corresponding to the designated example sentence to be output as a voice (steps B1 to B4 ( No)), the designated example sentence text is sent to the speech synthesis engine 21 as it is, and synthesized speech corresponding to each character of the example sentence text is generated and output from the speaker 18 as example sentence pronunciation speech (steps B5 to B7). ).

  Therefore, according to the dictionary search function and the voice output function by the mobile device (electronic dictionary) 10 having the above-described configuration, the pronunciation information is displayed on the explanation information display screen G2 of the desired headword (word) searched and displayed from the dictionary data 12b1. When an arbitrary word or example sentence is designated as a speech output target, “motion” M or “name” which are part-of-speech symbols existing in the dictionary explanation information of the headword included in the designated word or example sentence N is detected and a word is created by adding a speech synthesis command [<pron> verb] or [<pron> noun] set in advance according to this part-of-speech symbol immediately before the specified word or headword in the example sentence. Alternatively, a speech synthesis command for an example sentence is generated and given to the speech synthesis engine 21 for speech synthesis output processing, so that the specified word to be output or the headword in the specified example sentence has a different pronunciation depending on the part of speech. If there was Also, this can be without error learning accurately the user to pronounce the voice of a specified word or specified sentence to speech synthesis output.

  Further, in the dictionary search function and voice output function by the mobile device (electronic dictionary) 10 having the above-described configuration, if no part of speech symbol is detected from the dictionary explanation information of the specified word or the headword in the example sentence, the dictionary further includes A phonetic symbol in the description information is detected, and this phonetic symbol is converted into a phonetic symbol command for speech synthesis, and a predetermined phonetic symbol use command [<phoneme> ON] + phonetic symbol command is added to the specified word or example sentence. A speech synthesis command of a word or example sentence replaced with a headword is generated, and this is given to the speech synthesis engine 21 for speech synthesis output processing. In this case as well, as in the case where the part-of-speech symbol is detected, the speech synthesis command is used. Even if the specified word to be output or the headword in the specified example sentence has a different pronunciation depending on the part of speech, The user can learn the pronunciation sound of the specified example sentence without error.
