Abstract:
A system and a method for inputting characters with voice recognition are provided to enable a user to conveniently input the characters by completing entire character with the voice recognition after a part of the character is inputted through a general input device and user voice corresponding to the character is recognized. An input part(10) inputs a partial character. A voice input part(20) inputs the voice for entire character of the partial character. A voice recognition preprocessor(30) transfers the inputted partial character together with voice analysis information by analyzing the inputted voice. A voice recognizer(40) generates a candidate recognition list by using the partial character received from the voice recognition preprocessor and selects one of recognition candidates by performing a voice recognition process. A screen output part(50) outputs the finally recognized character and the candidate recognition list.

A system for controlling a sleeping atmosphere includes a receiver(122), a database(121), a sensing data analyzer(123), and a processor. The receiver receives a bio-signal from a user. The database stores sensing data analysis information for determining a sleeping state of the user based on the bio-signal. The sensing data analyzer browses the database based on the received bio-signals, analyzes the bio-signals, and generates a control signal for controlling a sleeping atmosphere of temperature user. The processor controls the sleeping atmosphere based on the control signal. The database stores the bio-signals corresponding to heart beats, blood pressures, and body temperatures.
