1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a method for constructing a semi-phoneme model in a speech recognition system, a method for verifying speech using the same, and a computer-readable recording medium having recorded thereon a program for realizing the methods.;2. The technical problem to be solved by the invention;In the present invention, the context-dependent (CD) phoneme in the speech recognition system is divided into training and test use, and a similar phoneme set composed of context-independent (CI) phonemes generated therefrom is recognized through training for each CD phoneme. By building a semi-phoneme model for speech verification used to perform the rejection function, a method to construct a semi-phoneme model to reduce training data and training time and to improve the performance of the system, and a method of verifying speech using the same, and to realize the above methods To provide a computer-readable recording medium that records a program for the purpose.;3. Summary of Solution to Invention;In the method for constructing a semi-phoneme model for speech verification applied to a speech recognition system, the present invention extracts features required for speech recognition from speech data input from the outside, and divides them into context-dependent (CD) phonemes. Collecting and classifying the classified phonemes into training context-dependent phonemes and test context-dependent phonemes; A second step of constructing a context-independent (CI) phoneme model through training by collecting the training context-dependent phonemes in a context-independent (CI) phoneme unit; And a similar phoneme set by performing a phoneme recognition test based on the test context-dependent (CD) phoneme and the context-independent (CI) phoneme model, and training through a similar phoneme set for each context-dependent phoneme (CD). Including the third step of building a phoneme model.;4. Important uses of the invention;The present invention is used in a voice recognition system.
