Abstract
Abstract Improved automated synthesis of human audible speech from text is disclosed. Performance enhancement of the underlying text comprehensibility is obtained through prosodic treatment of the synthesized material, improved speaking rate treatment, and improved methods of spelling words or terms for the sysstem user. Prosodic shaping of text sequences appropriate for the discourse in large groupings of text segments, with prosodic boundaries developed to indicate conceptual units within the text groupings, is implemented in a preferred embodiment.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
194 words
A method of synthesizing human audible speech from a multi-word string of text, the method comprising the steps of: treating the multi-word string as a single prosodic paragraph by performing the steps of: assigning a pitch to the beginning of the multi-word string that is higher than at the end of the multi-word string; and assigning a pitch to a final end point of the string that is lower than the pitch at any point within the string; including, in the multi-word string, following at least one of the individual words in the multi-word string, the corresponding spelling of the individual word; treating each individual word in the multi-word string as a single word declarative sentence; treating the spelling of each individual word included in the multi-word string as a single word declarative sentence; grouping each individual word and the corresponding spelling of the individual word into a prosodic group within the single prosodic paragraph, the prosodic group having a higher pitch at the beginning of the prosodic group than at the end of said prosodic group; and generating speech from the multi-word string as a function of the prosodic groupings and assigned pitch.
Claim 2
Independent Claim
194 words
A method of synthesizing human audible speech from a multi-word string of text, the method comprising the steps of: treating the multi-word string as a single prosodic paragraph by performing the steps of: assigning a pitch to the beginning of the multi-word string that is higher than at the end of the multi-word string; and assigning a pitch to a final end point of the string that is lower than the pitch at any point within the string; including, in the multi-word string, following at least one of the individual words in the multi-word string, the corresponding spelling of the individual word; treating each individual word in the multi-word string as a single word declarative sentence; treating the spelling of each individual word included in the multi-word string as a single word declarative sentence; grouping each individual word and the corresponding spelling of the individual word into a prosodic group within the single prosodic paragraph, the prosodic group having a higher pitch at the beginning of the prosodic group than at the end of said prosodic group; and generating speech from the multi-word string as a function of the prosodic groupings and assigned pitch.
Claim 3
Dependent Claim
42 words

Claim 5
Dependent Claim
