Written language parser system
First Claim
1. A converter for synthesizing a speech signal comprising:
- a word detector responsive to a freely generated text signal for detecting individual words in said text signal and developing thereby a string of words to be synthesized;
categorizing means for analyzing each word in the string of words with reference to N neighboring words in the string of words, where N is an integer, to determine the category to which each of the analyzed words belongs; and
syntax augmenting means responsive to said categorizing means for considering each word in the string and, in the process of considering each word, for inserting a pause generation signal in the string of words, before or after the considered word, when appropriate, based on the category of the considered word.

Abstract
An enhanced text-to-speech synthesizer accepts freely generated text sequences of words and synthesizes the received sequences with proper emphasis and with properly placed pauses. In combination with other elements, the synthesizer provides for an enhanced Dual Party Relay Service where the text generated by the sound-impaired party is synthesized without an attendant'"'"'s intervention. The text generated by users is made more intelligible by interpreting abbreviations, correcting errors (misspellings and "noise"), translating special terms that are used by the community of users, de-emphasizing words based on syntactic considerations and inserting pauses to enhance intelligibility.

26. A converter for synthesizing a speech signal comprising:
-
a word detector responsive to a freely generated text signal for detecting individual words in said text signal and developing thereby a string of words to be synthesized, said string of words forming a set; word modification means for transforming, in accordance with pre-established rules, said set formed by the detected string of words into a different set having another string of words; categorizing means, responsive to the other string of words from said different set, for analyzing each word in said other string of words with reference to N neighboring words in said other string of words, where N is an integer, and for determining thereby the categories to which each of the analyzed words belongs, syntax augmenting means responsive to said categorizing means for identifying pause-accepting words in said other string of words based on said categories and for inserting pause generation signals, in association with the identified words, into said other string of words to be synthesized. - View Dependent Claims (27)
