We thank God that in this congregation we have many gifted musicians and singers, helping us to worship with joy. When we worship here, we use organ, piano, synthesizer, drums, timpani, and instruments I don't even know what they are.

感谢神，在我们的会众当中，很多人有音乐的天赋，领导我们一起欢乐地敬拜；我们的敬拜团队使用了风琴、钢琴、合成乐器、鼓、定音鼓、还有许多我甚至不知道名称的乐器。

Our synthesis is characteristic of ready availability of starting material (piperonal, ethyl oxalate, allyl bromide, ethyl 4-bromobutyrate), operationally simple reactions with cheap reagent chemicals, and atom economy.

第一、二条合成线路前人未见报导，从中得到了四个苯并呋喃类衍生物，并详细地探索了环化反应的条件。

The word-to-sound rule and the structure of a speech database are modified during the implementation of TTS system, and then a filter algorithm based on part-of-speech is proposed to solve the polyphone problem. Prosodic research on Chinese characters plays a great role in speech recognition and speech synthesis system. In order to improve the naturalness of a speech synthesis system, the relationship among the sentence structure, the length of a sentence and the breath boundaries is analyzed and a breath boundary assigning algorithm based on such relationship is put forward. In addition, the author analyzes the process of a speech synthesis system and builds a prosodic markup language suitable for Chinese speech synthesis.

呼吸群边界划分作为汉语韵律的一种表现方式，它在语音感知和文语转换系统的性能方面起着十分重要的作用，作者在对汉语句法结构、句子长度和和呼吸群划分之间关系的研究基础上，设计并实现了基于句子长度和句法结构的呼吸群边界划分算法；为更好地描述文语转换过程，作者提出了适合汉语语音合成的SSML韵律标注语言，该标注语言不仅从声学层上对语音的韵律进行描述，而且从语言学层上标注句法结构信息，最后本文对基于语言理解的韵律规则用SSML进行了描述并用实验验证了语言学层面的标注对系统自然度的影响。
