Abstract: PURPOSE: A sound zoom apparatus coupled with image zoom control and a method thereof are provided to produce a sound source naturally coupled with the image zoom of a digital device by masking a noise removal signal, a remote sound source control signal, and a volume control signal with a front directivity-emphasized signal. CONSTITUTION: A first signal generator(110) generates a first signal for controlling peripheral noise removal from a sound source signal through a plurality of microphones by the coupling with an image zoom control function. A second signal generator(120) generates a second signal for controlling a remote sound source by the coupling with the image zoom control function. A sound zoom processor(130) generates a sound zoom signal according to the image zoom control with the reflection of the first and second signals and a third signal for volume control.

Abstract: A speech feature vector extracting apparatus and a method, and a speech recognition system and a method are provided to suppress pitch harmonic components for a speech spectrum to obtain a speech spectrum emphasizing formant, and to extract an exact feature vector based on the obtained speech spectrum, thereby improving speech recognition performance. A speech feature vector extracting apparatus includes a preprocessing unit(210), an FET processing unit(230), a formant emphasizing unit(250), a filter bank processing unit(270), and a DCT processing unit(290). The preprocessing unit constitutes a speech signal in units of frames. The FET processing unit converts the speech signal into a frequency signal. The formant emphasizing unit suppresses pitch harmonic components included in component components of the frequency signal to emphasize formant. The filter bank processing unit band-pass-filters the frequency signal using a mel-scale filter bank. The DCT processing unit performs a DCT process for each filter bank signal from the filter bank processing unit to extract a final MFCC feature vector.

Abstract: A method and device for automatically noting down telephone call contents, a call list display method, and a device therefor are provided to display stored memo information for a user in case a call list is inquired about after a call is terminated, thus the user can confirm call contents together with call details through displayed core word text memos. Call zones for interpreting a voice signal are set(102-110). The voice signal transceived in the set call zones is interpreted to extract core words included in the transceived voice signal(112). The extracted core words are set to memos, so that the set memos are stored(114). When a call is terminated, the stored memos are displayed(116,118). It is determined whether the displayed memos are tagged(120). The displayed memos are modified by a user(122).
