The Computer Vowel Trainer (CVT) uses linear prediction to estimate and display the shape of the speaker's vocal tract during an utterance. The assessment of the CVT was carried out over a period of three years with 14 profoundly deaf children divided into an experimental and a matched control group. Two main results were obtained: (a) children learning to articulate with the CVT achieve consistently higher articulation scores than those trained with conventional methods; (b) the younger the children, the greater their progress in vowel learning, retention and generalization.
计算机元音训练器（CVT）利用线性预测来估计并显示说话者发声时声道的形状。对CVT的评估持续了三年，14名重度失聪儿童被分为实验组和匹配的对照组。得到了两个主要结果：（a）使用CVT学习发音的儿童比使用传统方法训练的儿童在发音得分上始终更高；（b）儿童年龄越小，他们在元音学习、记忆和泛化方面的进步就越大。
