This article describes automatic evaluation of parameters for a connection model for speech synthesis units using DP (dynamic programming)- based matching. In speech synthesis by rule, choice of synthesis units (e.g., phonemes, syllables, mora, etc.) and their connections are very important for the quality of speech. Once synthesis units and the type of connecting method are given, then there comes the problem of optimizing the parameters for the connection model. The most widely used method for such a purpose is to use the human ear. Although the evaluation by human ear is the most desirable as the final evaluation, it is not only fairly listener-dependent but also time-consuming. In view of these points, a more efficient way is proposed for evaluating the connection without using the human ear.
