Abstract
A speech synthesis process can record concatenation costs of unit sequential pairs to a concatenation cost database for speech synthesis by synthesizing speech from a text, identifying an acoustic unit sequential pair in the speech, searching for a concatenation cost for the acoustic unit sequential pair in a database using a hash table for the database, and when the concatenation cost is not found in the database, assigning a default value as the concatenation cost for the acoustic unit sequential pair.
