METHOD FOR SELECTIVELY EMBODYING A METRE WITH RESPECT TO A SPECIFIC FORM IN A KOREAN DIALOGUE TEXT-TO-SPEECH SYSTEM TO VARIOUSLY EMBODY THE METRE SUITABLE FOR DIALOGUE CONNECTION OR A SENTENCE TYPE

摘要

PURPOSE: A method for selectively embodying a metre with respect to a specific form in a Korean dialogue text-to-speech system is provided to variously embody the metre suitable for dialogue connection or a sentence type by selectively extracting a corresponding speech segment from a synthesis unit DB. CONSTITUTION: If a pre-processed Korean dialogue sentence is inputted, a speech act tagging work of the input sentence is performed(S20). It is discriminated whether a specific element to selectively embody a metre is included in the input sentence in which the speech act tagging work is completed(S30). If the specific element is included, a tagging work of the specific element is performed using a work tagging table to correspond to speech act information of a preceding sentence and a following sentence including the specific element(S40). If a specific element with the same form to selectively embody the metre is not included in the input sentence, it is discriminated whether a question-type ending to selectively embody the metre is included in the input sentence(S50). It is discriminated whether the question-type ending to selectively embody the metre is included in the input sentence. If the question-type ending is included, a tagging work of the question-type ending is performed using a question-type ending tagging table to correspond to the question type(S60). If the question-type ending is not included in the input sentence, a text tagged to the specific element is output(S70). If a tagging text for the specific element is output, a corresponding speech segment is extracted from a synthesis unit DB to be suitable for a tag with a tagged form(S80). The extracted speech segments are added to the other speech segments to generate a dialogue synthesis sound(S90).
