    摘要: Disclosed is a method of generating a search network for voice recognition, the method including: generating a pronunciation transduction weighted finite state transducer by implementing a pronunciation transduction rule representing a phenomenon of pronunciation transduction between recognition units as a weighted finite state transducer; and composing the pronunciation transduction weighted finite state transducer and one or more weighted finite state transducers.

    摘要: The present invention allows a man to recognize a location of a sound source in a three-dimensional space using two ears and applies a method of separating a sound source in a certain orientation to improve the performance of an application technology using a speech in a noisy environment. The present invention acquires a speech signal using two sensors and determines an orientation angle of a sound source in a zero-crossing point step with respect to a frequency separated signal with a band pass filter bank. An object of the present invention is to obtain excellent sound source orientation detection and division performance which is difficult to be obtained in an existing crossing correlation method calculated in units of time frames in a noisy environment with a plurality of sound sources.
