Next, the operation of the above-mentioned portable terminal device will be described. This mobile terminal device differs from the conventional mobile terminal device in the ring tone, and is the same as the conventional mobile terminal device except for the ring tone. Therefore, the mechanism of generating the ringing tone will be described in detail below. When a mail arrives, this portable terminal device pronounces, as a ringing tone, a sound "Eueaao" which is obtained by converting each word of the voice "Mail" into a vowel with high and low pitches. Also, for example, when a call comes in from a friend "Aoki", each voice of "Aoki calls" is converted into a vowel, and the voice "Aoi Ana Aa En Aa Ao" is added to the pitch. Pronounce. The details of the mechanism are as follows.

First, before using the portable terminal device, the user inputs a voice for a ring tone. That is, when the user performs a key operation for instructing general-purpose voice input with the input key 4, the system CPU 1 detects it and outputs the voice CO
It outputs a vowel ringing tone generation instruction to the DEC 8. Voice COD
Upon receiving the instruction, the EC 8 switches the switch 8b (FIG. 3) to the bus line BU side. Next, when the user pronounces "It is a mail" into the microphone 10, the pronounced voice is converted into digital voice data by the A / D converter 8a (FIG. 3) and is transmitted through the bus line BU (FIG. 1). It is supplied to the system CPU 1 via. System CPU1
Causes the voice data to be temporarily stored in the system RAM 3.

Next, the system CPU 1 determines the system RA
"M" voice data and system ROM stored in M3
The vowel "e" of "M" is detected by comparing with the data showing the characteristics of each vowel in the vowel database DB1 (FIG. 2) in 2 and the program # "PC # 4" is preset in the system RAM3. Write in the designated area.
In the same manner, vowels are detected for each word "mail" and the program # is sequentially written in the system RAM 3. As a result, the next program #
Written to AM3. PC # 4 PC # 4 PC # 3 PC # 1 PC #
5

Next, the system CPU 1 uses the program #
To create MIDI data (MIDI standard data). FIG. 5 shows the structure of the created MIDI data. Here, the note may be, for example, a pitch when actually speaking, or a pitch of a favorite song may be used. Further, by changing the time data indicating the sounding timing included in the MIDI data, it is possible to give the sound to be sounded a rhythmic feeling. Next, the system CPU 1 writes the created MIDI data in the general-purpose sample table (see FIG. 6) in the system RAM 3.

Next, when the user pronounces "it is a phone call" into the microphone 10, in the same manner as described above, "it is a phone call" in the general-purpose sample table of the system RAM 3.
MIDI data is written and pronounced "sansan", the MIDI data of "sankara" is written to the general-purpose sample table of the system RAM3. Next, when the user performs a key operation for instructing the personal name voice input with the input key 4, the switch 8b of the voice CODEC 8 is switched to the bus line BU side as described above. Next, when the user pronounces, for example, "Aoki" toward the microphone 10, "Aoki" is MID by the same process as above.
It is converted to I data, and the telephone directory of the system RAM 3 (see FIG.
Reference). Next, the user is "Inoue" ...
・ If you pronounce "Wada" in sequence, those individual names will change to M.
It is converted to IDI data and written in the telephone directory.

Next, the operation of the portable terminal device shown in FIG. 1 when an incoming call is received will be described with reference to the flow chart shown in FIG. First, when the communication unit 6 receives an incoming call,
Data indicating the phone / mail distinction and the telephone number or mail address of the sender are output to the system CPU 1.
The system CPU 1 temporarily stores those data in the system RA.
Store in M3. Next, it is judged whether the incoming call is a telephone call or an incoming mail (step S1). Next, it is determined whether or not the caller's telephone number is registered in the telephone directory in the system RAM 3 (step S3). Then, if registered, the MIDI data corresponding to the registered name is transferred to the music reproducing unit 12 (step S4).

The MIDI data sent to the music reproducing section 12 is sent to the sequencer 16 via the interface 15 and is temporarily stored. The sequencer 16 uses the MIDI
The note data of the data is converted into a sound generation parameter and sequentially output to the WT sound source 17 together with the program #. The WT sound source 17 selects waveform data in the tone color ROM 19 based on the program #, reads the waveform data at a speed corresponding to the tone generation parameter, and outputs the waveform data to the D / A converter 20. The D / A converter 20 converts the output of the WT sound source 17 into an analog signal and outputs it to the speaker 13. This allows
A melody based on the Note data is added to the vowel voice of the sender's name and pronounced. For example, if the sender's name is "Aoki", the voice "Aoi" is pronounced from the speaker 13 with a melody.

Next, the system CPU 1 operates the system RA.
MIDI data corresponding to "san" is read from the general-purpose sample table of M3 (FIG. 6) and transferred to the music reproducing unit 12 (step S5). MIDI transferred
The data is converted into vowel sounds in the music reproducing unit 12 in the same manner as above, and is output to the speaker 13. As a result, the voice "Ahhhh" is generated from the speaker 13. Next, the system CPU 1 sets the system RAM 3
The MIDI data corresponding to "Telephone" is read from the general-purpose sample table (FIG. 6) and transferred to the music reproducing unit 12 (step S6). This makes it a "phone"
The speaker 13 produces a sound "Enahao" which is a vowel of each word.

Next, the system CPU 1 determines whether or not the off-hook button of the input key 4 has been operated (step S7). If the result of the determination is "NO", steps S4 to S6 are repeated. On the other hand, if the determination result is “YES”, the incoming melody reproduction end process is performed (step S8), and then the call process is performed (step S9). Then, when the on-hook button of the input key 4 is pressed (step S10), the process ends.

As described above, in the portable terminal device, for example, when there is a call from Mr. Aoki, each word of the words "I'm calling from Mr. Aoki" is converted into a vowel "Aoi Anah Enahao. Is generated as a ringing melody from the speaker 13. In addition, step S3 in FIG.
If the determination is “NO”, that is, if there is an incoming call from a person who is not registered in the telephone directory, then steps S4 and S5 are skipped and the process proceeds to step S6. As a result, only the vowel sound of "it is a telephone" is produced.

Next, when the mail arrives, the determination result of step S1 becomes "NO", and the process proceeds to step S12. In step S12, it is determined whether or not a mail has arrived. If it is a mail, an incoming mail display is displayed on the liquid crystal display 5 (step S13). Next, the system CPU 1 determines whether or not the incoming call address is registered in the telephone directory (step S14). Then, if the determination result is “YES”, the MIDI data corresponding to the registered name is read from the telephone directory and transferred to the music reproducing unit 12. As a result, a vowel of the name of the mail sender is generated from the speaker 13.

Next, the system CPU 1 reads out MIDI data corresponding to "sankara" from the general-purpose sample table and transfers it to the music reproducing section 12 (step S1).
6). As a result, the vowel of each word "sankara" is generated from the speaker 13. Next, the system CPU 1 determines from the general-purpose sample table the MID corresponding to "it is mail".
The I data is read and transferred to the music reproducing unit 12 (step S17). As a result, the vowel of each word "mail" is generated from the speaker 13. In addition, step S14
If the result of the determination is "NO", steps S15 and S1
Jump 6 and go to step S17. This allows
Only the vowel pronunciation of "It's email" is done.

In the above-described embodiment, the user pronounces the microphone 10 and the pronounced word is converted into MIDI data. Instead of this, the system ROM 2 is stored in the system ROM 2. A vowel database DB2 (not shown) for converting text data into vowels is stored in advance, and as shown in FIG.
Text data is input, the input text data is converted into vowels by the system CPU 1 using the vowel database DB2, and the vowels are converted into MIDI data and registered in the system RAM 3 (in the case of real-time reproduction, the music reproducing unit is used. 12).

The vowel ringing melody described above may be played back in synchronization with music or another sound effect. Further, the WT sound source 17 may be a PCM system or an ADPCM system, and if sound of "A" to "O" and "N" can be synthesized, a sound source other than the WT sound source, for example, F
It may be M sound source.

[0026]

As described above, the ring tone according to the present invention merely conveys the mood of the words by the vowel sounds, and the third party does not know what he / she is saying, while the user does not say what. You can know if there is an incoming call. The fact that the words are not clear has the advantage that it is something new and interesting to listen to, and it does not bother others. In addition, there is an advantage that it is possible to notify what the incoming call is, without the data amount becoming particularly large.
