Abstract

An apparatus and method for speech recognition and character displaying in a mobile telecommunication system. In a speech recognition and character displaying apparatus for a mobile phone, an RF Module processes a signal received from a base station or to be transmitted to the base station by radio, a speech/character conversion table has conversion data for use in converting voice data to character data, a speech recognition and character conversion unit converts the voice signal received from the base station to voice data using speech recognition and the voice data to character data by referring to the speech/character conversion table, a display displays the converted character data, and a controller provides overall control to the mobile phone, transmits a speech recognition notification request message to the base station in a speech recognition and character display mode, and controls the speech recognition and character display operation.

Claims

1. An apparatus for speech recognition and character displaying in a mobile station of a communication network, comprising:

a memory for storing a speech/character conversion table having conversion data for converting voice data to character data;

a speech recognition and character conversion unit for converting a voice signal to the voice data using speech recognition and converting the voice data to the character data, utilizing the speech/character conversion table; and

a controller for controlling the speech recognition and character conversion unit, and for transmitting the character data to a called party terminal.

2. The apparatus of claim 1, wherein the character data is transmitted to the called party terminal based on a message format.

3. The apparatus of claim 1, further comprising a transmitter for transmitting a voice information message to a calling party terminal to notify the called party terminal'"'"'s status and to enable a user of the calling party terminal to record a message by voice.

4. The apparatus of claim 2, wherein the message format is a short message service (SMS).

5. A method for speech recognition and character displaying in a mobile station of a communication network, comprising the steps of:

transmitting a paging message for an incoming call to a called party terminal;

converting a voice signal from a calling party terminal to character data using speech recognition and character conversion, in response to a request of the called party terminal; and

transmitting the character data to the called party terminal.

6. The method of claim 5, wherein the character data is transmitted to the called party terminal based on a message format.

7. The method of claim 5, further comprising the step, transmitting a voice information message to the calling party terminal to notify the called party terminal'"'"'s status and to enable a user of the calling party terminal to record a message by voice.

8. The method of claim 6, wherein the message format is a short message service (SMS).
