摘要:
Disclosed is a method for speech speaker recognition of a speech speaker recognition apparatus, the method including detecting effective speech data from input speech; extracting an acoustic feature from the speech data; generating an acoustic feature transformation matrix from the speech data according to each of Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA), mixing each of the acoustic feature transformation matrixes to construct a hybrid acoustic feature transformation matrix, and multiplying the matrix representing the acoustic feature with the hybrid acoustic feature transformation matrix to generate a final feature vector; and generating a speaker model from the final feature vector, comparing a pre-stored universal speaker model with the generated speaker model to identify the speaker, and verifying the identified speaker.

Provided are an apparatus and method for reporting speech recognition failures. The method includes detecting pure speech data from input speech data and outputting the detected pure speech data; checking at least one speech recognition failure for the pure speech data; and ascertaining speech recognition failure reasons from a check-result for the speech recognition failures and outputting the ascertained speech recognition failure reasons.

An apparatus and a method for providing an interworking service with a peripheral device in a Mobile Station (MS) supporting one or more wireless connectivity protocols are provided. Information on an execution environment of an application program for the interworking service is checked when the application program for performing the interworking service with the peripheral device is executed. A wireless connectivity protocol is selected from among the one or more wireless connectivity protocols for performing the interworking service with the peripheral device using the information on the execution environment of the application program.

An apparatus and method for localizing a sound source in a robot are provided. The apparatus includes a microphone unit implemented by one or more microphones, which picks up a sound from a three-dimensional space. The apparatus also includes a sound source localizer for determining a position of the sound source in accordance with Time-Difference of Arrivals (TDOAs) and a highest power of the sound picked up by the microphone unit. Thus, the robot can rapidly and accurately localize the sound source in the three-dimensional space with minimum dead space, using a minimum number of microphones.

A system and method for evaluating performance of a microphone for long-distance speech recognition, which enables a robot to receive and respond to voices. A robot, which includes a network robot, must correctly recognize speech in order to recognize the user and to perceive its surroundings, objective evaluation criteria are required for choosing a microphone to be used in the robot. The methods include measuring a degree of attenuation of the voice, measuring a degree of distortion of the voice, and simultaneously measuring the degree of attenuation of the voice and the degree of distortion of the voice. A standard for the choice of a microphone, which can be digitalized, for a speech recognition function of a robot, permits choice of a microphone which has good sensitivity and can pick up voices without distortion when used at a large distance.
摘要:
An apparatus and method for estimating audio signal spectrum information. The method including the steps of performing a morphological operation on a received audio signal, extracting peaks by using various peak extraction methods and extracting a remainder signal region from the extracted peaks, selecting a high-order peaks spectrum from the extracted remainder signal region. In addition, spectral envelopes are detected by performing an interpolation operation on the high-order peaks spectrum.

A method is provided for automatically adjusting a size of characters using a camera. The method includes receiving an image with characters; adjusting a focus of the image with characters and detecting a region and a size of characters in the image; determining whether the size of the characters in the image falls within a preset range; recognizing the characters in the image and displaying the recognition results, if the size of characters falls within the preset range; and automatically adjusting a zoom ratio of the image and recognizing the characters in the resized image, if the size of the characters does not fall within the preset range.

Disclosed is a method and an apparatus for recognizing characters using an image. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

Disclosed are a user input device and a method for rapidly selecting an operation mode in a mobile terminal having a touch screen input panel and a fingerprint recognition sensor. The user input method includes setting operation modes for at least one fingerprint data and input pattern, each comprised of keys necessary to implement a corresponding operation mode; detecting fingerprint data inputted from the fingerprint recognition sensor, and confirming an operation mode set for the inputted fingerprint data; and displaying an input pattern corresponding to the confirmed operation mode on the touch screen input panel.
