查询词典 in recent years

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。

In recent years, there has occurred many natural and artificial disasters domestic and outside continuously, not only cause the loss of all the people, but also threaten the safety of life. However when the disaster occurs, the urgent matter must the mobilization disaster relief personnel, rescue the equipment and fall as far as possible the disaster to lightly. The fast set out, effectiveness and disciplinal disaster relief unit, must be the military army. Depend on the army join to support disaster relief in several international serious disasters, then lets the entire disaster relief motion complete smoothly, and reduce damage and disaster to the smallest. Therefore, it takes the thorough research to improve the response capability of disaster relief in army.

中文摘要在近几年中，国内、外接连不断发生了许多天然、人为的灾害，不仅造成人民财产的损失，生命安全亦受到威胁，然而当灾害发生时，当务之急应当快速的动员救灾人员、装备抢救，尽可能将灾害降到最轻，而能够快速出动、有效率、有纪律支援的救灾单位，非军事部队莫属，且在国际上几次严重的大灾害中，都藉由军队加入支援紧急救灾，才让整个救灾的行动顺利完成，并将损伤、灾害减到最小，因此在本文中对於如何提升国军紧急救灾的应变能力作深入的研究。
