  FIG. 4 is a diagram showing an operation display state (part 1) associated with the dictionary search process of the portable device (electronic dictionary) 10.

  FIG. 5 is a diagram showing an operation display state (part 2) associated with the dictionary search process of the portable device (electronic dictionary) 10.

  For example, as shown in FIG. 4A, a search target character string (for example, “record”) is input and displayed in response to a user operation on the keyboard 14 on a search character string input screen G in which an English-Japanese dictionary is specified. And (step S1), the search word string “record” inputted based on the English-Japanese dictionary data stored in the database ROM 12b or the memory card 16 and a headword (word) having a spelling partially matching the character string ) Is searched, a search word list screen G1 for displaying a list of searched words (words) is displayed on the display unit 17 and the head search word “record” is highlighted. Designated and displayed by the cursor k (step S2).

  At this time, the explanation information corresponding to the headword (word) designated and displayed by the reverse cursor k is read and displayed on the preview screen Gp.

  Regarding the explanation information corresponding to the designated headword (word) read out from the dictionary data 12b1, the speaker mark M described at the head of the explanation mark indicates that the headword (word) is the pronunciation sound of native recording. It shows that the voice dictionary data 12b2 is included.

  Here, when the initial search word list screen G1 of the dictionary search process is displayed, the normal dictionary search mode is set (step S3).

  When the search term list screen G1 is displayed in the normal dictionary search mode and the “switch” key 14a of the keyboard 14 is operated and input (step S4), the current setting mode is the normal dictionary search mode. Since it is judged that there is (step S5 (Yes)), it is set to switch to the speech lemma dictionary search mode for displaying only the vocabulary with real speech as a search vocabulary list screen with speech G2. (Step S6).

  Then, among the plurality of headwords searched in the normal dictionary search mode and stored in the search headword memory 12c2, the headword in which actual voice data by native recording is stored as the voice dictionary data 12b2. Are extracted (step S7).

  Each of the search headwords with real voice data extracted in step S7 has a plurality of utterances such as different pronunciations depending on the part of speech or tense, even if the same word is spelled. Whether or not it is a headword is determined based on the explanation information in the dictionary data 12b1 corresponding to the headword (step S8).

  For example, if it is determined that the headword “record” searched according to the current search character string “record” is a headword having a plurality of pronunciation sounds with different pronunciations in nouns and verbs (step S8 ( Yes)), the noun and the verb are replaced with a plurality of different speech-specific words “record [noun]...” “Record [verb].

  Then, as shown in FIG. 4 (B), only the headword with actual speech extracted from each headword having a spelling that matches the input search character string “record” has another voice. In the case of the headwords having, it is displayed as a search word list screen with speech G2 replaced with voice-specific headwords “record [noun]...” “Record [verb]. The search headword “record [noun]...” Is designated and displayed by the reverse cursor k (step S10).

  If the search keyword list with voice G2 in the voice vocabulary dictionary search mode is displayed and the “switch” key 14a on the keyboard 14 is operated again, the normal dictionary search mode is set. Switching is set (steps S4 → S5 → S21), and as shown in FIG. 4A, the input search character string “record” and a headword (word that has a spelling partially matching the character string) ) Is searched again, and the search headword list screen G1 for displaying the searched headwords (words) as a list is displayed again on the display unit 17 and the head search headword “record” is displayed. Is displayed with the reverse cursor k (step S22).

  The up / down cursor on the keyboard 14 in the display state of the search word list screen G1 in the normal dictionary search mode or the display state of the search word list screen with speech in the voice word dictionary search mode G2 When the key 14c is operated (step S11), the designated headword position by the reverse cursor k on each headword list screen G1 or G2 is changed and displayed according to the direction indicated by the cursor (step S12). .

  Then, for example, in the display state of the search word list with speech search screen G2 in the voice word dictionary search mode as shown in FIG. 4B, the word-by-voice word “record [noun]. When the “speech” key on the keyboard 14 is operated in a state where is designated and displayed by the reverse cursor k (step S13), the headword “record [noun]...” Currently designated and displayed is the speech dictionary data 12b2. Is recorded as speech dictionary data 12b2 associated with the designated headword “record [noun]...”. Is read out and output from the speaker 18 (step S15).

  In this case, among the headwords displayed in the search list according to the search character string, only important headwords having real voice data can be displayed as the search headword list screen with speech G2. Even if any headword on the attached search headword list screen G2 is designated and displayed and the “voice” key is operated, a correct pronunciation voice by native recording can be heard.

  Moreover, in the case of a headword having the same headword but having different voices, for example, the headwords for each voice are replaced with “record [noun]…” “record [verb]…” separately. Since it is displayed, it is possible to easily listen to correctly different pronunciation sounds by the native recording by separately specifying and displaying the head words for each sound.

  On the other hand, when the “voice” key on the keyboard 14 is operated in the display state of the search word list screen G1 in the normal dictionary search mode as shown in FIG. 4A (step S13), the current If it is determined that the designated displayed headword is not a headword having actual voice data as the voice dictionary data 12b2 (step S14 (No)), the character string or pronunciation of the designated headword A synthesized speech based on each phoneme stored as synthesized speech data 12b3 is generated according to the symbol and is output from the speaker 18 (step S16).

  Also, for example, in the display state of the search word list with speech search screen G2 in the voice word dictionary search mode as shown in FIG. 4B, the word-specific word “record [noun]... When the “translation / decision” key 14b on the keyboard 14 is operated in a state in which it is designated and displayed by the reverse cursor k (step S17), the currently designated and displayed word “record [noun]... Since it is determined that the headword is replaced as another headword (step S18), as shown in FIG. 4C, the explanation information corresponding to the specified headword “record” is dictionary data. While being read from 12b1, this explanation information is displayed on the display unit 17 as an explanation information display screen G3 from the explanation portion which is designated by voice (in this case [noun]) (step S19).

  That is, as shown in FIG. 5 (D), by the operation of the cursor “↓” key 14c, the speech-specific headword “record [verb]... If the “translation / decision” key 14b on the keyboard 14 is operated in the changed display state (step S17), the currently specified headword “record [verb]... Since it is determined that the headword has been replaced as a word (step S18), as shown in FIG. 5E, the explanation information corresponding to the designated headword “record” is read from the dictionary data 12b1. At the same time, this explanation information is displayed on the display unit 17 as an explanation information display screen G3 from the explanation portion which is designated by voice (in this case [verb]) (step S19).

  In this case, in the search word list with sound search screen G2 in the sound word dictionary search mode, even if the word is the same word, the head words having different pronunciation sounds depending on the part of speech, tense, etc. In the explanation information display screen G3 that displays not only the replacement information but also the explanation information, for example, the meaning information in the case of [noun] reading and the meaning contents in the case of [verb] reading have different explanation information for each pronunciation. Since the portion can be described and displayed at the top, it is possible to clearly and easily learn explanatory information such as different meaning contents depending on the pronunciation.

  On the other hand, when the “translation / decision” key 14b on the keyboard 14 is operated (step S17), the headword currently designated and displayed is a headword that does not have different pronunciation depending on the part of speech, tense, etc. When it is determined (step S18 (No)), the explanation information read from the dictionary data 12b1 corresponding to the designated entry word is used as the explanation information display screen G3 from the top part as it is as the display unit 17. (Step S20).

  Therefore, according to the dictionary search voice output function of the mobile device (electronic dictionary) 10 having the above-described configuration, it is important for learning that has been carefully selected from a huge number of headwords (words) stored as the dictionary data 12b1. The speech dictionary data 12b2 of the pronunciation voice by native recording is stored in association with the headword (word), and a plurality of headwords corresponding to the search target character string input on the search character string input screen G are searched. When the “switch” key 14a is operated in the state where the search word list screen G1 in the normal dictionary search mode is displayed, the voice dictionary data 12b2 of the searched plural words is actually used. Only headwords having pronunciation voice data are extracted and displayed as a search headword list screen G2 with voice in the voice headword dictionary search mode, and a desired headword is designated and displayed by a reverse cursor k. When the “speech” key is operated, even if any headword is specified, the actual pronunciation voice data corresponding to the specified headword is read out and output as voice. Like a dictionary device, real speech is output for certain headwords, and voice is not output for certain headwords. Effective language learning is possible.

  In addition, according to the dictionary search voice output function of the mobile device (electronic dictionary) 10 having the above-described configuration, the search term list with speech in the search term dictionary search mode G2 has the same headword ( In the case of headwords that have different pronunciation sounds due to different parts of speech or tenses, the headwords are displayed by replacing them in parallel positions for each pronunciation. Can be specified and displayed separately, and the correct pronunciation difference due to the actual voice can be easily heard and learned.

  In addition, according to the dictionary search voice output function of the mobile device (electronic dictionary) 10 having the above-described configuration, the list is displayed by being replaced separately in the search word list with voice search screen G2 in the voice word dictionary search mode. For each of the same headwords with different pronunciations, each headword is designated and displayed, and the explanation information is displayed. The explanation information of the headword describes the meaning content for each pronunciation, such as the phonetic symbol. Since it is displayed from the explanation information part, it is possible to clearly and easily learn explanation information such as different meaning contents for each pronunciation of the same headword.
