Text to speech conversion system and method that distinguishes geographical names based upon the present position
First Claim
1. A text to speech conversion system that distinguishes geographical names based upon a present position, comprising:
- a text input unit for inputting text data;
a position coordinator input unit for inputting present location information of the text to speech conversion system; and
a text normalizer connected to said text input unit and said position coordinator input unit capable of generating a plurality of pronunciation signals indicative of a plurality, of pronunciations for a common portion of the text data, said text normalizer selecting one of the pronunciation signals based upon the present location information.

11. A text to speech conversion system that distinguishes geographical names based upon the present position comprising:
-
a text input unit for inputting text data; a phonetic rules synthesizer connected to said text input unit for converting phonetic symbols to phonetic signals; a voice generator connected to said phonetic rules synthesizer generating a voice output on the basis of the phonetic signals; a position coordinator input unit for inputting present location information of the text to speech conversion system and operationally connected to a geographical dictionary storing text having plural pronunciations with the same notation and coordinate data corresponding to the text data; a text normalizer connected to said text input unit and said phonetic rules synthesizer for converting the text data to the phonetic symbols based upon a morpheme analysis as well as a phoneme and prosody rules operation, said text normalizer selecting a pronunciation according to the present location information; and a present position update device connected to said text normalizer and said position coordinator input unit for renewing the location information corresponding to the text data which is outputted from the text input unit when the text input unit inputs the text data including geographical names.

22. A text to speech conversion apparatus that distinguishes geographical names based upon the present position comprising:
-
text input means for inputting text data; phonetic rules synthesizing means for converting phonetic symbols to phonetic signals; voice generating means for generating a voice output on the basis of the phonetic signals; position coordinator input means for inputting present location information of the text to speech conversion system; text normalizing means for converting the text data to phonetic symbols based upon a morpheme analysis as well as a phoneme and prosody rules operation, said text normalizing means selecting a pronunciation according to the present situation; and present position update means for renewing the coordinates data corresponding to the text data which is outputted from the text input means when the text input means inputs the text data including georaphical names.

23. A method of converting text to speech, comprising the steps of:
-
inputting text data; inputting a present location information; converting a common portion of the text data to multiple pronunciations; selecting one of the multiple pronunciations based upon the present location information; converting the text data to phonetic symbols on the basis of a morpheme analysis operation and a phoneme and prosody rules operation; inputting a present coordinates of the text to speech conversion system; and outputting a phonetic symbol that matches the inputted present coordinates of the text to speech conversion system and one of the coordinates data of plural pronunciations with the same notation, in the case that plural pronunciations are extracted with the same notation in a geographical dictionary, when the inputted text data have plural pronunciations as the consulting result of the geographical dictionary during morpheme analysis. - View Dependent Claims (24, 25, 26, 27, 28)
