Abstract: PURPOSE: A message service method using a voice recognition function is provided to offer a message by combining a voice recognition result and the real voice of a user. CONSTITUTION: A message server(20) recognizes a voice transmitted from a transmission terminal(10)(S14). The message server generates a recognized result from the voice and an N-best result based on a chaos network. The message server transmits the generated N-best result to the transmission terminal(S20). The message server receives the selected message from the transmission terminal and an evaluation result for the message accuracy(S26). The message server transmits the message and the evaluation result to a reception terminal(30)(S32). [Reference numerals] (10) Transmission terminal; (20) Message server; (30) Reception terminal; (S10) Inputting voice; (S12,S40) Transmitting the voice; (S14) Recognizing the voice; (S16) Generating a recognized result and an N-best result; (S18) Storing log data; (S20) Transmitting the recognized result and the N-best result; (S22) Displaying the recognized result and the N-best result; (S24) Determining a message and an evaluation result; (S26,S32) Transmitting the message and the evaluation result; (S28) Storing additional log data; (S30) Modifying errors of the recognized result; (S34) Displaying the message and the evaluation result; (S36) Requesting the voice; (S38) Extracting the voice; (S42) Outputting the voice

Abstract: PURPOSE: A voice signal pre-processing device and a method thereof are provided to interpolate and restore a voice signal whose size is abnormal under mobile environments, thereby increasing performance of recognizing a voice. CONSTITUTION: A voiced sound section detecting unit(120) detects a voiced sound section including a voiced sound signal from a voice section. A pre-processing method determining unit(140) detects a clipping signal which is generated during the voiced sound section. A clipping signal processing unit(160) extracts a signal sample close to the clipping signal. The clipping signal processing unit interpolates the clipping signal by using the signal sample.

Abstract: PURPOSE: A device for driving voice recognition system is provided to perform the voice recognition by vocalization of a pre-stored keyword without additional key operation, thereby increasing the user convenience. CONSTITUTION: When a user speaks a registration target keyword, a user registration unit(100) calculates a threshold value from the keyword. The user registration unit stores the threshold value in a storage unit(114). A voice recognition and driving unit(150) calculates a likelihood ratio for a vocalized data following the input of the vocalized data. The voice recognition and driving unit drives the system by comparing the likelihood ratio with the threshold value.
