`depicted in different drawings, will be designated by the
`Same reference numeral or character. Also, in the following
`description of the present invention, a detailed description of
`known functions and configurations incorporated herein will
`be omitted when it may make the Subject matter of the
`present invention rather unclear.
`0023 FIG. 1 shows the construction of a mobile terminal
`according to the present invention.
`0024) Referring to FIG. 1, an RF section 123 performs a
`wireleSS communication function of the mobile terminal.
`The RF section 123 comprises a RF transmitter for perform
`ing upward conversion and amplification of the frequency of
`a transmitted Signal and an RF receiver for amplifying a
`received signal with low noise and performing a downward
`conversion of the frequency of the Signal.
`0025. A modem 120 comprises a transmitter for coding
`and modulating a transmitted Signal and a receiver for
`demodulating and decoding a received signal. An audio
`
`8
`
`

`

`US 2005/0288063 A1
`
`Dec. 29, 2005
`
`processor 125 may compose a codec which comprises a data
`codec for processing packet data and an audio codec for
`processing an audio Signal Such as a speech Signal. The
`audio processor 125 converts a digital audio signal outputted
`from the modem 120 into an analog signal through the audio
`codec and reproduces the analog signal. Also, the audio
`processor 125 converts an analog audio signal generated
`from a microphone into a digital audio signal and transmits
`the digital audio signal to the modem 120. The codec can be
`provided as an independent element or included in a control
`Section 110.
`0026. A memory 130 may be composed of a program
`memory and a data memory. The program memory includes
`programs for controlling general operations of the mobile
`terminal and those for performing a function corresponding
`to a key input through Voice recognition according to the
`present invention. The data memory temporarily Stores data
`generated during implementation of the above programs.
`0027. The control section 110 controls the overall opera
`tions of the mobile terminal. The control section 110 may
`include the modem 120 and the codec. In the preferred
`embodiments of the present invention, the control Section
`110 controls implementation of a function or shift into a
`mode for voice recognition according to the length of time
`during which a specific key is pressed. When a specific
`function key is pressed, the control Section 110 controls
`implementation of a corresponding function or shift into a
`mode for performing the function through Voice recognition
`according to the current mode of the mobile terminal. If a
`Voice recognition key has been pressed before any other key
`input, the control section 110 activates a mode for perform
`ing a function corresponding to the other key through Voice
`recognition.
`0028. A camera module 140 is used to take pictures of an
`object on which its lens focuses. The camera module 140
`comprises a camera Sensor for converting a photographed
`optical Signal into an electric Signal and a Signal processor
`for converting an analog image signal photographed by the
`camera Sensor into digital data. Supposing that the camera
`Sensor is a CCD (charge coupled device) sensor, the signal
`processor can be a DSP (digital signal processor). The
`camera Sensor and the Signal processor can be either inte
`grated into a single element or Separated as independent
`elements.
`0029. An image processor 150 generates picture data for
`displaying an image Signal outputted from the camera mod
`ule 140. The image processor 150 processes image Signals
`outputted from the camera module 140 in frames. Also, the
`image processing Section 150 adjusts the frame image data
`to conform to the size and other features of a display Section
`160 and outputs the adjusted frame image data. The image
`processor 150 comprising an image codec compresses the
`frame image data displayed on the display Section 160 in a
`preset manner or restore the compressed frame image data to
`the original frame image data. The image codec is Selected
`from a variety of Still or moving picture codecs, Such as
`JPEG codec, MPEG4 codec or Wavelet codec. Supposing
`that the image processor 150 has an OSD (on screen display)
`function, it can output OSD data according to the displayed
`picture size under the control of the control section 110.
`0030 The display section 160 displays image data out
`putted from the image processor 150 or user data outputted
`
`from the control section 110. When using an LCD, the
`display section 160 may comprise an LCD controller, a
`memory for Storing image data and an LCD device. When
`the LCD is a touch Screen, it can Serve as an input Section.
`The display Section 160 can display a voice dialing Section
`consisting of first to third input Sections in a voice dialing
`mode according to the present invention.
`0031. A key input section 127 is provided with keys for
`inputting numbers and characters and function keys for
`Setting up various functions. The key input Section 127 may
`also include keys for performing predetermined functions or
`initiating modes for voice recognition according to the
`present invention. The key input Section 127 may include
`first to third keys for performing predetermined functions or
`initiating modes for voice recognition according to the
`present invention. The first key can be used to perform a
`predetermined function or to enter a voice name dialing
`mode or a voice telephone number dialing mode. The Second
`key can be used to perform a predetermined function or to
`enter a voice menu Search mode. The third key can be used
`to perform a predetermined function or to enter a voice
`phonebook Search mode.
`0032) A voice recognizer 170 detects the start and end
`points of a Sound made by the user and inputted through a
`microphone. Upon extracting characteristic data in a speech
`Section excluding muteS preceding and following the
`Speech, the Voice recognizer 170 performs vector quantiza
`tion on the data in realtime. The voice recognizer 170 detects
`a word most Similar to the characteristic data from the words
`recorded in a database. The voice recognizer 170 converts
`the detected word into a character Signal which is then
`displayed on the Voice dialing Section of the display Section
`160.
`0033. The process of activating a mode for performing a
`function through Voice recognition on a mobile terminal
`having the above structure will be explained in detail with
`reference to FIGS. 2 to 5.
`0034 FIG. 2 is a flow chart showing a process of
`activating a mode for performing a function through Voice
`recognition on a mobile terminal according to the first
`embodiment of the present invention. In the first embodi
`ment, it is Supposed that the first, Second and third keys
`provided on the key input Section 127 are a Send key, a menu
`key and a phonebook key, respectively.
`0035. The process according to the first embodiment will
`be explained in more detail with reference to FIG. 1.
`0036 When a user presses the send key in a standby
`mode of step 201, the control section 110 detects the key
`input at Step 202 and measures the length of time during
`which the send key is pressed. When the control section 110
`detects that the Send key is pressed over a predetermined
`period of time at step 203, it proceeds with step 204 to enter
`a Voice dialing mode for making a call through Voice
`recognition. At step 204, the control section 110 also deter
`mines the type of Voice dialing mode. If a voice name dialing
`mode has been Set to be activated when the Send key is
`pressed over the predetermined period of time, the control
`section 110 will activate the voice name dialing mode in
`which the user can Say a recipient's name to initiate an
`outgoing call to a stored telephone number of the recipient
`through voice recognition. If a voice telephone number
`

`recipient to initiate an outgoing call to the telephone number
`through voice recognition. When the control section 110
`detects that the Send key is pressed for a period shorter than
`the predetermined period of time at step 203, it proceeds
`with step 205 to control the display section 160 to display a
`list of recently dialed telephone numbers. When the user
`Selects one of the telephone numbers displayed on the
`display section 160, the control section 110 performs a
`function of initiating an outgoing call to the Selected tele
`phone number.
`0037. When the user presses the menu key in the standby
`mode of step 201, the control section 110 detects the key
`input at Step 206 and measures the length of time during
`which the menu key is pressed. When the control section 110
`detects that the menu key is pressed over a predetermined
`period of time at step 207, it proceeds with step 208 to enter
`a voice menu Search mode for Searching for a menu through
`voice recognition. When the control section 110 detects that
`the menu key is pressed for a period shorter than the
`predetermined period of time at step 201, it proceeds with
`step 209 to control the display section 160 to display all
`available menus of the mobile terminal.
`0.038. When the user presses the phonebook key in the
`standby mode of step 201, the control section 110 detects the
`key input at Step 210 and measures the length of time during
`which the phonebook key is pressed. When the control
`section 110 detects that the phonebook key is pressed over
`a predetermined period of time at Step 211, it proceeds with
`Step 212 to activate a voice phonebook Search mode for
`Searching for a name and a corresponding telephone number
`through voice recognition. When the control section 110
`detects that the menu key is pressed for a period shorter than
`the predetermined period of time at Step 211, it proceeds
`with Step 213 to activate a general phonebook Search in
`which the user can Search for a name or a telephone number
`in a phonebook Stored in the mobile terminal.
