System and method for synthesis of speech from provided text
First Claim
1. A method for generating parameters in a speech synthesis system, wherein the system comprises a parameter generation module operatively coupled to a speech synthesis module, using a continuous feature stream, for provided text for use in speech synthesis, comprising the steps of:
- a) partitioning, by the parameter generation module, said provided text into a sequence of phrases;
b) generating, by the parameter generation module, parameters in a continuous approximation for said sequence of phrases using a speech model; and
c) processing, by the parameter generation module, the generated parameters to obtain an other set of parameters, wherein said other set of parameters comprise at least one clamped delta value and wherein said other set of parameters are utilized in speech synthesis for provided text by the speech synthesis module.

Abstract
A system and method are presented for the synthesis of speech from provided text. Particularly, the generation of parameters within the system is performed as a continuous approximation in order to mimic the natural flow of speech as opposed to a step-wise approximation of the feature stream. Provided text may be partitioned and parameters generated using a speech model. The generated parameters from the speech model may then be used in a post-processing step to obtain a new set of parameters for application in speech synthesis.
