Text-to-speech conversion system and method having function of providing additional information

A text-to-speech conversion system, comprising:

• a speech synthesis module for analyzing text data in accordance with morphemes and a syntactic structure, synthesizing the text data into speech by using obtained speech synthesis analysis data, and outputting synthesized sounds;
• an emphasis word selection module for selecting words belonging to specific parts of speech as emphasis words from the text data by using the speech synthesis analysis data obtained from the speech synthesis module;
• and
• an information type-determining module for determining information type of the text data by using the speech synthesis analysis data obtained from the speech synthesis module, and generating sentence pattern information;
• and
• a display module for rearranging the selected emphasis words in accordance with the generated sentence pattern information and displaying the rearranged emphasis words in synchronization with the synthesized sounds.

A text-to-speech conversion method, the method comprising the steps of:

• a speech synthesis step for analyzing text data in accordance with morphemes and a syntactic structure, synthesizing the text data into speech by using obtained speech synthesis analysis data, and outputting synthesized sounds;
• an emphasis word selection step for selecting words belonging to specific parts of speech as emphasis words from the text data by using the speech synthesis analysis data;
• and
• a display step for displaying the selected emphasis words in synchronization with the synthesized sounds.
