SPEECH SYNTHESIS FROM ACOUSTIC UNITS WITH DEFAULT VALUES OF CONCATENATION COST

摘要

A speech synthesis system can select recorded speech fragments, or acoustic units, from a very large database of acoustic units to produce artificial speech. When a pair of acoustic units in the database does not have an associated concatenation cost, the system assigns a default concatenation cost. The system then synthesizes speech, identifies the acoustic unit sequential pairs generated and their respective concatenation costs, and stores those concatenation costs likely to occur.

1. A method comprising:
synthesizing speech from a text; identifying a most common acoustic unit sequential pair in the speech; assigning a concatenation cost to the most common acoustic sequential pair; and recording the concatenation cost of the most common acoustic sequential pair to a concatenation cost database.
