对节日单元选择语音合成系统[1]中使用的目标代价进行了研究。我们的最终目标是自动学习一个感知上最优的目标成本函数。在本研究中，我们调查了一种细分类型的目标成本行为。目标成本是基于计算几个上下文特征中的不匹配。使用了/n ei/和/ei m/的所有147820种可能的组合，合成了一个载体句（“我的名字是罗杰”）。选出92个有代表性的版本作为460个两两比较呈现给听众。听众的偏好投票被用来分析目标成本的行为，相对于其组成语言语境特征的价值。
We describe an investigation of the target cost used in the Festival unit selection speech synthesis system [1]. Our ultimate goal is to automatically learn a perceptually optimal target cost function. In this study, we investigated the behaviour of the target cost for one segment type. The target cost is based on counting the mismatches in several context features. A carrier sentence (“My name is Roger”) was synthesised using all 147,820 possible combinations of the diphones /n ei/ and /ei m/. 92 representative versions were selected and presented to listeners as 460 pairwise comparisons. The listeners’ preference votes were used to analyse the behaviour of the target cost, with respect to the values of its component linguistic context features.
