In order to decrease the error rate of speech recognition, speaker adaptation techniques are often used to adjust speaker-dependent acoustic models. MLLR (Maximum Likelihood Linear Regression) and MAP are two of the most popular techniques in recent years. MLLR uses the technique of regression trees. It calculates the transform matrix for each leaf node of the tree. This makes it possible to use fewer sentences to decrease the error rate of HMM-based speech recognition. However, while we examined the recognition result, we found that although the overall error rate decreased, but the error rate of certain confusable phones was higher. In order to solve this problem, we propose the use MPE (Minimum Phone Error Discriminative Training) to solve this problem.

在语音辨识技术的实际应用上，语者调适技术常被用做调整语者无关之声学模型，使其对於特定语者之辨识率有所提升，常见的语者调适技术有最大化相似度线性回归（Maximum Likelihood Linear Regression），其精神在於透过对语音辨识模型相近的mixture做群聚，再对各个群聚做调整，以期能达到利用少量语料，提升辨识率的目的，但其缺点为，在发音上相近的模型，其mixture原本就极为近似，若再分类为同一群聚做调整，容易因为使用者的发音习惯，而使模型偏向ㄓ或ㄗ，因此虽然整体的辨识率获得提升，但却造成混淆音的错误率上升。

The experimental results indicated that the longer the po uring intervallic time of the two kinds of molten metal and the higher the heigh t of the molten iron to pour into the tip of dipper teeth , the narrower its tran sitional zone will be, on the contrary, the wider its transitional zone will be.

用不同粘度的流体通过水力模拟的方法近似地描述了双金属斗齿过渡区的混合状态。试验结果表明：两种液体浇注的间隔时间越长，先浇入的铁液液面越高，过渡区越窄；反之，过渡区越宽。生产中为了保证过渡区双金属的结合质量，应控制较高的铁液液面高度及一定的双液间隔时间
