of the HMM approach. The discriminant function approach achieves higher performance by using a criterion that minimizes directly the errors due to misclassification. In speech synthesis, articulatory models and automatic methods for determining their parameters offer the best hope of providing the needed flexibility and naturalness in synthesizing a wide range of speech materials.
