Abstract
Abstract A method, system and process to improve the formant composition in a speech synthesis system so that the formants are more intelligible. The system employs a process in the memory of a processor to change the starting and ending frequency of particular phonemes (210) from the frequency of the independent phonemes. The process examines (240) preceding and succeeding ending phoneme frequency values to detect similar phoneme frequency values. If a dissimilar value is detected, then the invention provides (250) for exchange of the formants to render the resulting speech more intelligible. <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
A speech synthesis apparatus, comprising: (a) memory means for receiving information; (b) means for identifying and parsing at least a first formant and a second formant in the information; (c) means for comparing the first formant and the second formant; (d) means for swapping the first formant and the second formant if the first formant and the second formant do not match; and (e) means for synthesizing the information into audio information.
Claim 2
Dependent Claim
16 words
An apparatus as recited in claim 1, including a digital signal processor for processing the information.
Claim 3
Dependent Claim
27 words
An apparatus as recited in claim 1, including analog to digital conversion means for receiving audio information and converting it to information that a computer can process.
Claim 4
Dependent Claim
27 words
An apparatus as recited in claim 1, including digital to analog conversion means for receiving information that a computer can process and converting it to analog information.
Claim 5
Dependent Claim
13 words
An apparatus as recited in claim 1, including means for storing the information.
Claim 6
Independent Claim
65 words
A method for speech synthesis, comprising the steps of: (a) receiving information; (b) identifying and parsing at least a first formant and a second formant in the information; (c) comparing the first formant and the second formant; (d) swapping the first formant and the second formant if the first formant and the second formant do not match; and (e) synthesizing the information into audio information.
Claim 7
Dependent Claim
19 words

Claim 8
Dependent Claim
21 words
A method as recited in claim 6, including the step of converting analog information to information that a computer can process.
Claim 9
Dependent Claim
24 words
A method as recited in claim 6, including the step of receiving information that a compute can process and converting it to analog information.
Claim 10
Dependent Claim
14 words
A method as recited in claim 6, including the step of storing the information.
