METHOD AND SYSTEM FOR SPEECH SYNTHESIS
First Claim
1. A method for performing speech synthesis to a textual content at a client data processing system, the method comprising:
- performing speech synthesis to the textual content based on a current acoustical unit set Scurrent in a corpus at said client;
analyzing said textual content and generating a list of target units with corresponding context features;
selecting multiple acoustical unit candidates for each target unit according to said context features based on an acoustical unit set Stotal that is more plentiful than the current acoustical unit set Scurrent in the corpus at said client;
determining acoustical units suitable for speech synthesis for said textual content according to said multiple unit candidates; and
updating the current acoustical unit set Scurrent in the corpus at said client based on the determined acoustical units.

Abstract
A method for performing speech synthesis to a textual content at a client. The method includes the steps of: performing speech synthesis to the textual content based on a current acoustical unit set Scurrent in a corpus at the client; analyzing the textual content and generating a list of target units with corresponding context features, selecting multiple acoustical unit candidates for each target unit according to the context features based on an acoustical unit set Stotal that is more plentiful than the current acoustical unit set Scurrent in the corpus at the client, and determining acoustical units suitable for speech synthesis for the textual content according to the multiple unit candidates; and updating the current acoustical unit set Scurrent in the corpus at the client based on the determined acoustical units.

8. A system for enabling speech synthesis to a textual content at a client data processing system, the system comprising:
-
speech synthesis means configured to perform speech synthesis to the textual content based on a current acoustical unit set Scurrent in a corpus on said client; analysis means configured to analyze said textual content and generate a list of target units with corresponding context features; selection means configured to select multiple acoustical unit candidates for each target unit according to said context features based on an acoustical unit set Stotal that is more plentiful than the current acoustical unit set Scurrent in the corpus at said client; determining means configured to determine acoustical units suitable for speech synthesis for said textual content according to said multiple unit candidates; and update means configured to update the current acoustical unit set Scurrent in the corpus on said client based at the determined acoustical units. - View Dependent Claims (9, 10, 11, 12, 13, 14)
