A method of searching music using speech recognition in a mobile device, the method including: recognizing a speech signal uttered by a user as a phoneme sequence; and searching music information by performing partial symbol matching between the recognized phoneme sequence and a standard pronunciation sequence.

Method and apparatus for searching multimedia data using speech recognition in mobile device

An apparatus for reducing a noise signal of a speech signal in a speech recognizer, the apparatus estimating a signal to noise ratio for each frequency band of the speech signal, applying a noise suppression rate based on the estimated signal to noise ratio, and reducing the noise signal of the speech signal.

Apparatus and method of reducing noise by controlling signal to noise ratio-dependent suppression rate

A speech recognition method including: layering a central lexicon in a tree structure with respect to recognition-subject vocabularies; performing multi-pass symbol matching between a recognized phoneme sequence and a phonetic sequence of the central lexicon layered in the tree structure; and selecting a final speech recognition result via a Viterbi search process using a detailed acoustic model with respect to candidate vocabularies selected by the multi-pass symbol matching.
