Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external view of a mobile phone according to an embodiment of the present invention. Mobile phone 1
Numeral 01 designates a key operation unit 106 including an off-hook button 102, an on-hook button 103, a ten-key button 104, and a mode switching button 105 on the front surface of the housing. The off-hook button 102 shifts to a call state by pressing the button at the time of incoming or outgoing call, and the on-hook button 103 shifts to a standby state by pressing the button in the call state.

A mode switching button 105 switches between two modes, a "sound effect sending mode" in which a sound effect is added to a call sound during a voice call, and a "normal mode" in which no sound effect is sent. Pressing the key of the mode switching button 105 is valid in both the call state and the standby state. A sound effect sending button 107 is arranged on the side of the housing.
If the user is in a call state and is in the sound effect sending mode, pressing the sound effect sending button 107 executes the sound effect sending unit.

The ten key buttons 104 are "0-9",
It consists of "#" and "*", and is used when inputting the telephone number of the connection destination or inputting the hiragana, katakana, and symbols assigned to each key. The contents input by the ten key buttons 104 are displayed on the display unit 108. The telephone number of the connection destination input by pressing the numeric key button 104 can be transmitted by pressing the off-hook button 102.

Similarly, when the sound effect sending button 107 is depressed and the sound effect sending means is executed, when the user is in a call state and in the sound effect sending mode, the ten key button 104 is depressed to set the sound effect. It is possible to execute the sending means. The sound effect sending button 107 may have a role of a shortcut key that can register the contents of the numeric keypad 104 corresponding to frequently transmitted sound effects.

The antenna 109 is mounted on the upper surface of the mobile phone, the receiver 110 is mounted on the upper side of the display unit 108, and the microphone 111 is mounted on the key operation unit 10.
6 attached to the lower side.

FIG. 2 is a block diagram showing a circuit configuration of a portable telephone according to an embodiment of the present invention. First, the ten-key input unit 210 includes a ten-key button 104, an off-hook button 102, an on-hook button 103, and a power button 1
12 and provides an interface with the user. The key signal input by the ten key input unit 210 is input to the control unit 205, and the input content is displayed on the display unit 2
09 is displayed.

The mode switching button 105 and the sound effect sending button 107 are interface units which play an important role for executing the sound effect sending means, and the key signals input by the mode switching button 105 and the sound effect sending button 107 Is input to the control unit 205.

The microphone 111 converts audio data input by the user into an analog signal, and inputs the converted analog audio data to the sound effect mixer 202. The sound effect mixer 202 creates synthesized sound data of the sound effect data stored at a predetermined address of the storage device 203 (the ROM 203a or the RAM 203b) and the analog sound data input from the microphone 111. Storage device 203
The sound effect data stored at a predetermined address of the (ROM 203a or RAM 203b) is stored in a digital signal data format. Therefore, when creating a synthesized voice with the sound effect mixer 202, the D / A
After the digital / analog converter converts the digital signal into an analog signal, the signal is synthesized with the analog audio data input from the microphone 201.

Here, the sound effect transmitting means will be described in detail with reference to FIG. First, the sound effect is transmitted when the ten key input unit 210 or the sound effect transmission button 107 is pressed in the voice communication state and the sound effect transmission mode. Therefore, in order to transmit the sound effect, it is necessary to first press the mode switching button 105 to switch the mode of the mobile phone to the “sound effect transmission mode”. If the mode of the mobile phone is the “normal mode”, the switch SW403 in FIG.
The path for the sound effect data from the storage device is disconnected.

When the mode is switched to the sound effect sending mode, the switch SW 403 is closed by the control unit 205, and a path for sound effect data from the storage device 203 is established. In the sound effect transmission mode in which the path from the storage device 203 is established, when the ten key 104 is pressed, the sound effect data corresponding to the pressed key is read from the storage device 203 by the control unit 205 at regular intervals, and the sound effect mixer The data is written to the D / A converter 404 of 202. The sound effect data written in the D / A converter 404 is converted into analog sound effect data, and is synthesized with the analog sound data in the mixer 202.

In synthesizing the sound effect data and the analog voice data, the synthesizing of the sound effect data and the analog voice data is started at the timing of pressing the ten-key button from the ten-key input unit 210. In the sound effect transmission mode, as shown in FIG. 5, each key of the numeric keypad 104 is associated with a stored sound effect and a storage address of the sound effect in the storage device 203. For example, when key 1 in FIG. 5 is pressed, sound effect 1 associated with key 1 is stored in storage device 203.
The sound effect 1 data is read from the upper address addr 1, and is read via the D / A converter 404.
Sent to Further, the sound effect name associated with the key 1 is displayed on the display unit 209 in a predetermined display format at the timing when the key 1 is pressed.

The sound effect mixer 202 is controlled by the control unit 205. If there is no predetermined sound effect transmission operation, the sound effect mixer 202 does not perform the processing for synthesizing the sound effect, and The obtained analog audio data is output to the audio processing unit 206 as it is. In the audio processing unit 206, the synthesized audio data created by the sound effect mixer 202 is converted from an analog signal to a digital signal by an A / D converter 206a in the audio processing unit 206. The synthesized speech data converted into a digital signal is subjected to codec processing by a speech codec 206c.

The radio section 207 performs modulation processing on the synthesized speech data that has been subjected to codec (encoding) processing by the speech processing section 208, and transmits the modulated speech data to the base station via the antenna section 208. The radio unit 207 is controlled by the control unit 205, and transmits the synthesized voice data modulated by the antenna unit 109 to the base station at the timing specified by the control unit 205.

On the other hand, the modulated voice data transmitted from the base station is received by the antenna
After the demodulation process by the radio unit 207 under the control of 5, the decoding process is performed by the audio codec 206c of the audio processing unit 206. The decoded received audio data is
The digital signal is converted into an analog signal by the D / A converter 206b.

The received sound data converted into the analog signal is controlled by the control unit 205 to receive the sound effect mixer 202.
Is input to When there is no predetermined sound effect sending operation described later in the sound effect mixer 202, the received sound data that is input is directly input to the receiver 110. The receiver 110 receives the received audio data output from the sound effect mixer 202, and reproduces the received audio from the receiver 110.

When a predetermined sound effect transmission operation described later is performed during a voice call, the sound effect mixer 202
The sound effect data and the received sound data stored in the RAM 203 a or the RAM 203 b are synthesized, and the synthesized sound data is output to the receiver 205. The synthesized voice data is
It is reproduced from the receiver 204. The display unit 209 displays an input from the numeric keypad input unit 210 and the mode switching button 105.
, And the change of the state of the mobile device by pressing the sound effect transmission button 107 is displayed. The mode switching button 105 plays a role of switching between a normal mode for performing a normal voice call and a sound effect transmission mode for transmitting a sound effect in a call state.

The operation of the sound effect transmitting method during a call will be described with reference to FIG. First, a determination 301 is made as to whether the power of the mobile phone 101 is ON. If the power is on, the process transits to the waiting state 302. If the power is not on, the determination 301 is repeated until the power is turned on.

When the power of the mobile phone 101 is turned on and the mobile phone 101 is in a state of transition to the standby state 302 and there is an outgoing call or an incoming call, the mobile phone 101 makes a determination 303 as to whether or not it is in a call state. If it is determined, the state shifts to a call state. If the mobile phone 101 is not in a call state, the process returns to the standby state 302. If the mobile phone 101 is in a call state, a determination 304 is made as to whether or not the mode of the call state is the sound effect transmission mode.

There are two types of communication modes, a normal mode and a sound effect transmission mode. If the mode of the call state is the normal mode, a normal voice call is performed without performing a process of adding a sound effect to the call voice. When the mode switch button 105 is pressed while the communication mode is the normal mode, the mode is switched to the sound effect transmission mode. Pressing the mode switching button 105 again switches the mode from the sound effect transmission mode to the normal mode.

If the communication mode is the sound effect transmission mode, it is determined at 305 whether the sound effect transmission button 107 or the numeric keypad button 104 has been pressed during the voice call, and the sound effect transmission button 107 or the numeric keypad is determined. If the button 104 is not pressed, a normal voice call is performed during that time. The call state mode is the sound effect transmission mode,
If the press of the sound effect transmission button 107 or the numeric keypad button 104 is detected during the voice call, the sound effect corresponding to the pressed button is transmitted at 306.

In the call state in the sound effect transmission mode or the call state in the normal mode, whether or not the call is ended is determined by 3
If it is determined in step 07 that the call is not terminated, the process is repeated from the determination 304 of the sound effect transmission mode. If the call is not terminated and the power is not turned off, the process returns to the standby state 302.

In the embodiment of the present invention, the mode switching button 105
By pressing the button and setting the voice communication mode to the sound effect transmission mode, by pressing the numeric key button 104, a means for adding a sound effect previously assigned to the numeric key button 104 to the call voice and providing a means for transmitting the voice sound. did. However, in this embodiment, the ten key button 1
In order to output a sound effect at the timing of pressing the keypad 04, when pressing the numeric key button 104, the user removes his / her ear from the main body of the mobile phone 101, particularly the receiver 110, and checks the numeric key button 104 on the front of the mobile phone 101, The ten key button 104 is pressed. Therefore, there is a problem in that the voice of the other party cannot be heard at the moment when the ear is away from the receiver because the ten-key button 104 is pressed.

Therefore, as another embodiment of the present invention,
Instead of the means for assigning the sound effect added to the call sound to the numeric keypad 104, a sound effect is assigned to a specific word (keyword) in the call sound, and when the keyword is uttered during the conversation, the keyword is corresponded ( Provide a means for sending out (assigned) sound effects. For example,
"This song" in the call voice saying "I have a band called xx now, do you know this song?"
Is registered in advance as a keyword, and when the user utters the keyword “this song” and recognizes the keyword spoken by the user on the mobile phone, a sound effect corresponding to the keyword is transmitted.

The keyword detection process is started at the timing of depressing a voice recognition button (not shown in FIG. 1, a button arranged on the side of the housing corresponding to the sound effect transmission button 107) during a voice call, and is fixed. The voice recognition processing is performed on the call voice of the time, and as a result of the voice recognition, it is determined whether or not there is an utterance (keyword) that matches the keyword registered in advance, and the sound effect data is transmitted.

The above embodiment will be described with reference to FIG. First, the mode switch button 211 is pressed in the standby state or the call state to set the sound effect transmission mode.
In the “sound effect sending mode”, the numeric keypad 10 as shown in FIG.
4 is associated with the stored sound effect name and the storage address of the sound effect in the storage device, but when the keyword is detected by using voice recognition, the sound effect name Instead, a keyword (recognized word) is registered in advance. In this case, the “key” number in FIG. 5 is replaced with the “keyword registration number”, and the “stored sound effect” is replaced with the “keyword”.

Here, in the speech recognition processing, it is assumed that a similarity between a keyword (recognized word) and an input speech is calculated using an encoded speech. Therefore, the keyword (recognized word) to be registered is stored in a predetermined address of the storage device 203 together with the registration number of the keyword in the same format as the data format encoded by the voice codec. The keyword (recognized word) to be registered is also stored in the voice recognition unit, used for comparison with the input voice at the time of voice recognition processing, and the recognition result is notified to the control unit 205.

In a call state, the analog sound input from the microphone 201 in FIG. 6 is amplified by the amplifier 401 and input to the sound effect mixer 202. Sound effect mixer 202
In the example, since the ten key button 104 is not pressed, the operation of synthesizing the sound effect is not performed, and the input analog voice is input to the voice processing unit 206 as it is. The audio processing unit 206 converts analog audio data input without any processing by the sound effect mixer 202 into an A /
The analog signal is converted into a digital signal by the D converter 206a, and a codec (encoding) process is performed by the audio codec 206c. Here, if the voice recognition button 405 is not pressed, the voice recognition unit does not perform the recognition processing.

When the voice recognition button 405 is pressed, voice recognition processing is performed on voice data that has been subjected to codec (encoding) processing for a predetermined time from the time when the button was pressed. As a result of the voice recognition, when the input voice data is determined to be a registered keyword (recognized word), the control unit 205 is notified of a registration number corresponding to the keyword (recognized word) registered in advance, and the notification is performed. The received control unit 205,
The sound effect data corresponding to the keyword (recognized word) is read from a predetermined address of the storage device 203, and the sound effect sending process is performed. If a keyword registered in advance is detected during a voice call, a sound effect corresponding to the keyword is added to the call voice and transmitted. If no keyword is detected, no sound effect is transmitted.

According to this embodiment, since the sound effect is transmitted using a specific word of the sound as a trigger for transmitting the sound effect, the sound effect can be transmitted more smoothly than pressing the ten-key button. In the description of this embodiment, the method of performing the recognition process on the voice uttered by the user has been described. However, the recognition process may be performed on the voice uttered by the other party, and the sound effect transmission process may be performed. .

[0040]

As described above, according to the first aspect of the present invention, the sound effect data read from the storage device and the sound data are synthesized by the sound effect mixer in accordance with the signal from the sound effect transmission button. Therefore, it is possible to add a sound effect to be appropriately inserted at an arbitrary timing of the user during the conversation, and it is possible to enhance the sensibility effect.

According to the second aspect of the present invention, a sound effect is assigned to a specific keyword in a call voice, and when it is determined that the voice data is a registered keyword, a sound effect corresponding to the keyword is transmitted. By providing the means for performing the communication, it is possible to transmit the sound effect without having to place the call in the middle.

According to the third aspect of the invention, since the sound effect data is read from the storage address in the storage device corresponding to the depressed numeric keypad, various sound effects can be transmitted by a simple operation.

According to the fourth aspect of the present invention, by providing a mode switching button for switching between a sound effect sending mode in which a sound effect is added to a call voice and transmitting it and a normal mode for operating the mobile phone, the sound effect is provided.
